TextView is not selectable with ontouchListener

TextView is not selectable with ontouchListener - java

I have implemented ontouchListener in my activity to detect swipes left and right. However, enabling this feature stopped me from being able to make my text selectable and accordingly getting the default android text selection cursor, menu.
After many trials, now i can perfectly call the onLongClick() method when long clicking the textView. However, still the text is not selectable. also, whenever I disable the swipe detection, the Text selection works perfectly.
public class PreviewActivity extends AppCompatActivity
{
TextView question;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_preview);
question = (TextView)findViewById(R.id.question);
question.setTextSize(TextViewSize);
question.setTextIsSelectable(true);
question.setLongClickable(true);
question.setFocusableInTouchMode(true);
View prev_act = (View) findViewById(R.id.question);
prev_act.setOnTouchListener(new OnSwipeTouchListener(this) {
#Override public void onSwipeLeft() {
if(RowIndex>0){
Qtitle = ListItems.get(RowIndex-1);
Query();
//text = Query();
//question.setText(text);
questionSC.scrollTo(0,0);
RowIndex--;
}
}
#Override public void onSwipeRight() {
if(RowIndex<ListItems.size()-1){
Qtitle = ListItems.get(RowIndex+1);
Query();
//text = Query();
//question.setText(text);
questionSC.scrollTo(0,0);
RowIndex++;
}
}
#Override public void onLongClick() {
Log.v(this.toString(), "Long click.");
question.setCursorVisible(true);
question.performLongClick();
}
});
}
And the OnSwipeTouchListener class is as the following:
public class OnSwipeTouchListener implements OnTouchListener {
private final GestureDetector gestureDetector;
public OnSwipeTouchListener (Context ctx){
gestureDetector = new GestureDetector(ctx, new GestureListener());
}
#Override public boolean onTouch(View v, MotionEvent event) {
return gestureDetector.onTouchEvent(event);
}
private final class GestureListener extends SimpleOnGestureListener {
private static final int SWIPE_THRESHOLD = 250;
private static final int SWIPE_VELOCITY_THRESHOLD = 200;
#Override
public void onLongPress(MotionEvent e) {
onLongClick();
super.onLongPress(e);
}
#Override
public boolean onDown(MotionEvent e) {
return true;
}
#Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
boolean result = false;
try {
float diffY = e2.getY() - e1.getY();
float diffX = e2.getX() - e1.getX();
if (Math.abs(diffX) > Math.abs(diffY)) {
if (Math.abs(diffX) > SWIPE_THRESHOLD && Math.abs(velocityX) > SWIPE_VELOCITY_THRESHOLD) {
if (diffX > 0) {
onSwipeRight();
} else {
onSwipeLeft();
}
result = true;
}
}
} catch (Exception e) {
e.printStackTrace();
}
return result;
}
}
public void onSwipeRight() {
}
public void onSwipeLeft() {
}
public void onSwipeTop() {
}
public void onSwipeBottom() {
}
public void onLongClick() {
}
}
I want to be able to select a portion (text) from the TextView and having the swipe detector along it.

After trying for a while this is what worked highlighting and selecting text enabling copy,paste,selectall ... etc
you will need to add onTouch snippet in the prev_act.setOnTouchListener(new OnSwipeTouchListener(this) {
#Override
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
if (event.getAction() == MotionEvent.ACTION_DOWN) {
//do stuff here
Log.i("clicking", "onActionDown");
}else if(event.getAction() == MotionEvent.ACTION_UP) {
question.performLongClick();
}
return false;
}
#Override public void onLongClick() {
}

The answer was very simple:
#Override
public boolean onDown(MotionEvent e) {
return false;
}
I had to set the onDown() to return false.

Recorded file name is wrong

first of all, I'll explain the expected behavior of the App.
What does the App do?
When I run the App I see this view:
Now if you hit the "+" button you'll see this Dialog:
By clicking Add this entry will be added to a ListView. I added two items. This looks like this:
Expected Result
Now when I touch and hold the mic icon of the list items it should start recording audio through the device microphone and then save this recording with the name of the bold entry, that means e.g. the first recording will get the name A.3gp, the second one B.3gp and so on..
Actual Result (UPDATE 07.12.2017)
The current state is:
Every item in the list gets his "own" recording. That means if I touch and hold the microphone icon of the first item in the list, it is doing what it should do. The same goes for all other items on the list.
When I add the first item A, then touch its record icon, a file will be created with the name A.3gp (which is correct behavior).
When I add the second item B then do nothing and then add a third item C and touch the record icon for B, a file will be created with the name C.3gp (which is not a correct behavior, it should be B.3gp).
Now to the fun part.
Code (UPDATE 07.12.2017)
1. The Model
public class Word {
private String mForeignTranslation;
private String mDefaultTranslation;
private ImageView mRecordIconImageResourceId;
private MediaRecorder mMediaRecorder;
public Word(String foreignTranslation, String defaultTranslation, ImageView recordIconImageResourceId) {
this.mForeignTranslation = foreignTranslation;
this.mDefaultTranslation = defaultTranslation;
this.mRecordIconImageResourceId = recordIconImageResourceId;
}
public Word(String foreignTranslation, String defaultTranslation) {
this.mForeignTranslation = foreignTranslation;
this.mDefaultTranslation = defaultTranslation;
}
public String getDefaultTranslation() {
return mDefaultTranslation;
}
public String getForeignTranslation() {
return mForeignTranslation;
}
public ImageView getRecordIconImageResourceId() {
return mRecordIconImageResourceId;
}

2. The Adapter

});
return listItemView;

I would appreciate any help. Thanks in advance.

In the startAudioRecording() method of the Activity, you set the output filename from the foreignWord field. The problem is that the foreignWord field is set to the most recently added foreign word each time the user submits a word pair in the Add Word dialog. Thus each time the user starts a recording, the name of the output file will be set to the last foreign word added.
Instead of using fields for recordingImageView, foreignWord, defaultWord, foreignWord, audioSavePath, and mediaRecorder, you should make them local variables, and pass them as parameters to your record(), startAudioRecording(), stopAudioRecording() methods with the following steps:
Just delete those fields from the beginning of the class so that you see some compilation errors where the fields were used.
Where you see an undefined variable on the left side of an assignment, make the variable local (Ctrl+V in Android Studio).
Where you see an undefined variable elsewhere, make the variable a parameter of the method (Ctrl+P).
It should work after those changes.
`

Kindly move this snippet :
recordingImageView.setOnTouchListener(new View.OnTouchListener()
{
#Override public boolean onTouch(View view, MotionEvent motionEvent)
{
switch (motionEvent.getAction())
{
case MotionEvent.ACTION_DOWN:
{ recordingImageView.setImageResource(g startAudioRecording(position);
break;
}
case MotionEvent.ACTION_UP:
{
recordingImageView.setImageResource(R.drawable.mic_black);
stopAudioRecording();
break;
}
}
return true;
}
});
In Adapter , getView(...) Below accessing recordImageView.
And put startAudioRecording() , stopAudioRecording() in same adapter or all relevant method for recording is to be in Adapter.
So by this you will get click on in each individual image view. Previously when you are fetching it will only take instance of any one image view.
Now update code on "startAudioRecording()" as:
private void startAudioRecording()
{
if (checkPermission())
{
if (wordsArrayList != null)
{
audioSavePath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/" + wordsArrayList.get(position) + ".3gp";
getMediaRecorderReady();
}
}
}
Now your second point, saving its name by any name. Will cover by above code.
Thanks and happy coding

ListActivity not loading adapters style, loading white screen

I am working in android studio with GSON and Retrofit 1, which is stable. I am in need to find out why non of the information is showing, the GSON should be putting the JSON information in the model class of getters/setters.

How to hide part of layout when editText is selected

Is there a way how to hide some buttons when i click on EditText and keybord shows?
I have this layout
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/InnerRelativeLayout">
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:stretchColumns="1"
android:id="#+id/table">
<TableRow
android:id="#+id/tariffRow">
<TextView
android:layout_column="1"
android:text="Název"
android:padding="3dip" />
<EditText
android:id="#+id/tariffName"
android:gravity="right"
android:padding="3dip" />
</TableRow>
</TableLayout>
</ScrollView>
<LinearLayout android:id="#+id/InnerRelativeLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_alignParentBottom="true">
<Button android:id="#+id/okBtn"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:text="Ok"/>
<Button android:id="#+id/stornoBtn"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="center"
android:text="Storno" />
</LinearLayout>
Now when the editText is clicked to type some value i need to hide that linearLayout android:id="#+id/InnerRelativeLayout" because otherwise it is still visible above the keyboard.

Need to set a FocusChangeListener to the EditText which triggers whenever focus changes on that EditText as follow:
editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
// hide relative layout
} else {
// show relative layout
}
}
});

It is not actually that simple, here is my solution how I got it working.
First Need to create MyEditText.java
public class MyEditText extends EditText {
private KeyImeChange keyImeChangeListener;
public MyEditText(Context context, AttributeSet attributeSet) {
super(context, attributeSet);
}
public void setKeyImeChangeListener(KeyImeChange keyImeChange){
keyImeChangeListener = keyImeChange;
}
public interface KeyImeChange {
public boolean onKeyIme(int keyCode, KeyEvent keyEvent);
}
#Override
public boolean onKeyPreIme (int keyCode, KeyEvent keyEvent){
if(keyImeChangeListener != null){
return keyImeChangeListener.onKeyIme(keyCode, keyEvent);
}
return false;
}
}
Then layout.xml, change following
<EditText
android:id="#+id/tariffName"
android:gravity="right"
android:padding="3dip" />
Into
<!-- change yourapp -->
<com.yourapp.MyEditText
android:id="#+id/tariffName"
android:gravity="right"
android:padding="3dip" />
Add also android:focusable="true" to your LinearLayout
<LinearLayout android:id="#+id/InnerRelativeLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_alignParentBottom="true"
android:focusable="true">
Then put into your activity like MainActivity.java,
import fi.hgs.apps.MyEditText.KeyImeChange;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
removeFocus();
MyEditText myEditText = (MyEditText) findViewById(R.id.tariffName);
myEditText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
#Override
public void onFocusChange(View v, boolean hasFocus) {
if(!hasFocus) {
showLinearLayout();
} else {
hideLinearLayout();
}
}
});
myEditText.setKeyImeChangeListener(new KeyImeChange() {
#Override
public boolean onKeyIme(int keyCode, KeyEvent event) {
if (KeyEvent.KEYCODE_BACK == event.getKeyCode()) {
removeFocus();
}
return false;
}
});
}
Add also these to do the actual job.
public void removeFocus() {
LinearLayout linearLayout = (LinearLayout)findViewById(R.id.InnerRelativeLayout);
linearLayout.requestFocus();
}
public void showLinearLayout() {
LinearLayout linearLayout = (LinearLayout)findViewById(R.id.InnerRelativeLayout);
linearLayout.setVisibility(View.VISIBLE);
}
public void hideLinearLayout() {
LinearLayout linearLayout = (LinearLayout)findViewById(R.id.InnerRelativeLayout);
linearLayout.setVisibility(View.INVISIBLE);
}

I am executing this code on pre-honeycomb emulator. But when i move the center image it gets hides behind the left and right images respectively.
I want center image to shown on the rest of two images and also want to show that two images also.
Basically, the center image is a circle and rest two images are browser and lock images and i want that circle to overlaps that images.
I am working on a lock screen.
Please help in my layout problem and how i can solve this problem?????

You can try changing your layout as follows...
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<view
android:id="#+id/image"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.example.screenlock.MainActivity$IV"
android:scaleType="center" />
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom|fill_horizontal" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#60000000"
android:orientation="horizontal"
android:padding="7dp" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0"
android:scaleType="fitXY"
android:src="#drawable/ic_launcher" />
<View
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_weight="1" />
<ImageView
android:id="#+id/imageView3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right|fill_vertical"
android:layout_weight="0"
android:scaleType="fitXY"
android:src="#drawable/ic_launcher" />
</LinearLayout>
<ImageView
android:id="#+id/imageView2"

How to scroll an image horizontally?

I have a problem with horizontal scroll view.
This is my XML code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/relative_layout_id"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/bg"
tools:context=".MainActivity" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/home_title_id"
android:text="#string/home_title"
android:layout_marginTop="#dimen/forty_text_size"
android:textColor="#android:color/white"
android:layout_centerHorizontal="true"
android:gravity="center"
android:textSize="#dimen/forty_text_size" />
<LinearLayout
android:id="#+id/linear_layout_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/home_title_id">
<HorizontalScrollView
android:id="#+id/horizontal_view_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<ImageView
android:id="#+id/home_image_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/abc" />
</HorizontalScrollView>
</LinearLayout>
</RelativeLayout>
In my Java class, extending activity I have declared all the widgets, then i created a class scrollview, extending horizontal scroll view.
The Java code is as follows:
class scrollview extends HorizontalScrollView
{
private static final int SWIPE_MIN_DISTANCE = 5;
private static final int SWIPE_THRESHOLD_VELOCITY = 300;
private ArrayList mItems = null;
private GestureDetector mGestureDetector;
private int mActiveFeature = 0;
public scrollview(Context context)
{
super(context);
}
public void setFeatureItems(ArrayList items)
{
LinearLayout internalWrapper = new LinearLayout(getContext());
internalWrapper.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
internalWrapper.setOrientation(LinearLayout.HORIZONTAL);
addView(internalWrapper);
this.mItems = items;
for(int i = 0; i< items.size();i++)
{
LinearLayout featureLayout = (LinearLayout) View.inflate(this.getContext(),R.layout.activity_main,null);
//...
//Create the view for each screen in the scroll view
//...
internalWrapper.addView(featureLayout);
}
setOnTouchListener(new View.OnTouchListener()
{
#Override
public boolean onTouch(View v, MotionEvent event)
{
//If the user swipes
if (mGestureDetector.onTouchEvent(event))
{
return true;
}
else if(event.getAction() == MotionEvent.ACTION_UP || event.getAction() == MotionEvent.ACTION_CANCEL )
{
int scrollX = getScrollX();
int featureWidth = v.getMeasuredWidth();
mActiveFeature = ((scrollX + (featureWidth/2))/featureWidth);
int scrollTo = mActiveFeature*featureWidth;
smoothScrollTo(scrollTo, 0);
return true;
}
else
{
return false;
}
}
});
mGestureDetector = new GestureDetector(new MyGestureDetector());
}
class MyGestureDetector extends SimpleOnGestureListener
{
#Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY)
{
try
{
//right to left
if(e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY)
{
int featureWidth = getMeasuredWidth();
mActiveFeature = (mActiveFeature < (mItems.size() - 1))? mActiveFeature + 1:mItems.size() -1;
smoothScrollTo(mActiveFeature*featureWidth, 0);
return true;
}
//left to right
else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY)
{
int featureWidth = getMeasuredWidth();
mActiveFeature = (mActiveFeature > 0)? mActiveFeature - 1:0;
smoothScrollTo(mActiveFeature*featureWidth, 0);
return true;
}
} catch (Exception e) {
Log.e("Fling", "There was an error processing the Fling event:" + e.getMessage());
}
return false;
}
}
}
But nothing happens, please help.
ORWILL IT BE BETTER TO HAVE THE SCROLL CLASS IN THE ONTOUCH LISTNER FUNCTION???

Wrong tag placement in your layout.xml file i think. Place LinearLayout having ImageView in HorizontalScrollView instead of HorizontalScrollView in LinearLayout as below:
<HorizontalScrollView
android:id="#+id/horizontal_view_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/home_title_id" >
<LinearLayout
android:id="#+id/linear_layout_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/home_image_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/abc" />
</LinearLayout>
</HorizontalScrollView>

there is no need for java coding here. this java coding is required only for SWIPE functionality
the XML coding alone is enough!!!but, in the following format
<HorizontalScrollView
android:id="#+id/horizontal_view_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/home_title_id" >
<LinearLayout
android:id="#+id/linear_layout_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/home_image_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/abc" />
</LinearLayout>
</HorizontalScrollView>
as horizontal scroll can hold only one child node.

We Keep Coding

Java is a programming language and computing platform first released by Sun Microsystems in 1995.

TextView is not selectable with ontouchListener - java

The answer was very simple: #Override public boolean onDown(MotionEvent e) { return false; } I had to set the onDown() to return false.
