"Swipe Detection" attached to textview is malfunctioning

"Swipe Detection" attached to textview is malfunctioning - java

I am trying to detect "Left Swipe", "Right Swipe" and "Down Swipe".

And the Gesture detection code,
OnSwipeTouchListener.java
This code is from here
package k.k;
import android.view.GestureDetector;
import android.view.GestureDetector.SimpleOnGestureListener;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnTouchListener;
public class OnSwipeTouchListener implements OnTouchListener {
private final GestureDetector gestureDetector = new GestureDetector(new GestureListener());
public boolean onTouch(final View v, final MotionEvent event) {
return gestureDetector.onTouchEvent(event);
}
private final class GestureListener extends SimpleOnGestureListener {
private static final int SWIPE_THRESHOLD = 100;
private static final int SWIPE_VELOCITY_THRESHOLD = 100;
#Override
public boolean onDown(MotionEvent e) {
return super.onDown(e);
}
#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) {
result = onSwipeRight();
} else {
result = onSwipeLeft();
}
}
} else {
if (Math.abs(diffY) > SWIPE_THRESHOLD && Math.abs(velocityY) > SWIPE_VELOCITY_THRESHOLD) {
if (diffY > 0) {
result = onSwipeBottom();
} else {
result = onSwipeTop();
}
}
}
} catch (Exception exception) {
exception.printStackTrace();
}
return result;
}
}
public boolean onSwipeRight() {
return false;
}
public boolean onSwipeLeft() {
return false;
}
public boolean onSwipeTop() {
return false;
}
public boolean onSwipeBottom() {
return false;
}
}
This code works fine as it should in Virtual Device, but to my surprise, it is not working on real device! I have Micromax Canvas2, and I tested with my phone and HP phone, in both this is not working.
Not working means, I think it do not identify any of the swipes properly. "Sometimes" it does swipe to left and right, but that is "sometimes" and for that also I had to drag it very hard 3-4 times.
What is wrong here? This is not working because I implemented the listener to a TextView?
PS: I posted the completed related classes here because last time it was impossible to get a suitable answer with code removed.

I found the answer. The case is, here what I have is a ScrollView which is by default responding to swipes and my text view was inside that. So, the only fix was taking the TextView out of the ScrollView.

Did you try to wrap the TextView in a container (Linear/RelativeLayout) and implement the listener to the container?
For example:
...
<LinearLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="#+id/paragraph_reader_txt"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="200dp"
android:ems="30"
android:singleLine="false"
android:clickable="true"
>
</TextView>
</LinearLayout>
...
and then:
LinearLayout parag = (LinearLayout)findViewById(R.id.container);
parag.setOnTouchListener(paraSwiped);
EDIT:
I used swipe like so:
parag.setOnTouchListener(new OnSwipeTouchListener(){
public boolean onSwipeRight(){
//your stuff
return true;
}
public boolean onSwipeLeft(){
//your stuff
return true;
}
...
});
It works for me

Audio stops after startBluetoothSco in Android 11

The moment I bind an Android 11 device using startBluetoothSco I loose audio. It works fine till Android 10
Sample code I tried with below.
Audio works as it should when i do not bind using startBluetoothSco.
I also added queries tag in AndroidManifest.xml

I was able to figure it out. I did try it once before, but didn't work then. Not sure why.
Document reference AudioManager#startBluetoothSco
public void TextToSpeechButton(View view) {
Bundle ttsBundle = new Bundle();
//Setting the stream to STREAM_VOICE_CALL was the key
ttsBundle.putInt(TextToSpeech.Engine.KEY_PARAM_STREAM, AudioManager.STREAM_VOICE_CALL);
textToSpeech.speak(editText.getText().toString(), TextToSpeech.QUEUE_FLUSH, ttsBundle, null);
}

My Problems that not solved are
The app is not working when I add an onItemclicklistener to the list view.
bluetooth search result is filling with the same device name.
I cannot access the buttons after viewing pairing devices and
scanned devices(it seems like that the same layout is popping to screen).
Anyone please help me to solve these issues.
Thanks in advance.

You can just do like this -
mListView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Toast.makeText(getApplicationContext(), " ITEM CLICKED POSITION = "+String.valueOf(position), Toast.LENGTH_SHORT).show();
}
});

You can add OnItemClickListener like this
mListView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) { {
Toast.makeText(getApplicationContext(),String.valueOf(arg2), Toast.LENGTH_LONG).show();
}
});`

look at this code it contain how you set the list view listener with detect the clicked row and getting sub view in that row
ListView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// TODO Auto-generated method stub
View row= adapter.getView(position, view, parent);
CheckBox box=(CheckBox) row.findViewById(R.id.checkBox1);
box.performClick();
}
});
adapter is your list view adapter
hope it help

FrameLayout doesn't handle touch request correct when having 2 layers

I'm trying to extend FrameLayout to be capable to decide for which view to pass the touch event:
myApp is like this:
The dots are in horizontal scrollview, and the rectangle is just a view.
When you touch the dots area it's scrolls. I would like the rectangle to be draggable.
I can do that one at a time(I mean - if the frame has only one child). but not both.
I've figured I need to override: onInterceptTouchEvent but didn't manage to pass the event to the rectange View. here is my code:
activity_main.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent"

</View>

mTable.addView(row[i]);
}//outer loop
long end = cal.getTimeInMillis();
Log.d(TAG, "time of operation=" + end + ", " + start + ", " + String.valueOf(end - start));
}

I resolved the issue by switching the order inside the FrameLayout.
apparently the framelayout set the layers in opposite order. i.e.:
<FrameLAyout>
<View1/>
<View2/>
</FrameLAyout>
View2 will be on the upper layer. View2 will first gets the touch callbacks, if it is not handling the touch, View1 will get a call.
I.e. It is the same as drawing. the bottom layer is View1, the upper is View2. make sense

If I remove the setContentView from the onCreate method, I get an error:
java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.CharSequence android.support.v7.widget.Toolbar.getTitle()' on a null object reference
Any ideas on what I can do to correct this?
Screenshot:

You need to add a android.supprt.v7.widget.Toolbar to your layout and then do this in the onCreate method of your ActionBarActivity
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActitionBar(toolbar);
Also, make sure your theme uses Theme.AppCompat.NoActionBar (or Theme.AppCompat.Light.NoActionBar)

FWIW - i just retrofitted some ABS stuff to the newer Toolbar stuff that you are on and had some issues with the Title not showing up in all Frgments, activities.... Some worked some did not. Very frustrating to have varied outcomes. Had to replicate the following code in places where i did not think it should be needed due to inheritance and due to calls to 'super.onCreate()'..
toolbar = (Toolbar) findViewById(R.id.toolbar);
if (toolbar != null) {
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowTitleEnabled(true);
After populated the above code everywhere in those activities/frags where it did NOT show up, the issue resolved.
Really odd that ur title flashes up then disappear.. something is repainting the view!

I found out that I needed to
<include layout="#layout/toolbar_layout"/>
in my activity's layout file since I had my toolbar layout defined in its own xml file.

"Swipe Detection" attached to textview is malfunctioning - java

I found the answer. The case is, here what I have is a ScrollView which is by default responding to swipes and my text view was inside that. So, the only fix was taking the TextView out of the ScrollView.
