I'm trying add a listener to a ImageButton that is on a widget but i can't.
My widget xml is:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#09C"
android:padding="#dimen/widget_margin"
>
<ImageButton
android:id="#+id/activityCheck"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="8dp"
android:background="#09C"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:text="Hecho"/>
</RelativeLayout>
The method that i need execute when the imageButton "activityCheck" is pressed is the next:
public void changeColor(View view) {
Log.d("changeColor", "PASE POR AQUÍ");
ImageButton button = view.findViewById(R.id.activityCheck);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
_changeColor(v);
}
});
}
How can I do it?
in layout add
android:clickable="true"
in ImageButton tag.
this will made your image clickable and then it will detect any click events.

I am trying to create a simple PopupWindow with a text entry field.
I know there are many questions of this type, but none seem to solve my problem. This is the XML of my popup layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:background="#color/white"

android:padding="15dp"
android:layout_gravity="center"
android:layout_height="wrap_content">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Dodaj produkt po identyfikatorze"
android:textSize="15sp"

/>
<EditText
android:layout_width="match_parent"
android:textSize="20sp"
android:hint="Identyfikator"
android:minWidth="250dp"
android:id="#+id/insert_edit"
android:gravity="center"
android:layout_height="match_parent" />
<LinearLayout
android:layout_width="match_parent"

android:gravity="center"
android:layout_height="wrap_content"
android:id="#+id/insert_cancel"
android:text="Anuluj"/>
</LinearLayout>
</LinearLayout>
Now, I want to create this layout in my main activity when a FAB is pressed. This is how I do it:
public class ScrollingActivity extends AppCompatActivity {
private ActivityScrollingBinding binding;
private int ACTIVITY_LOAD_DATABASE = 1;
AbstractDatabase database;
RowAdapter rowAdapter;
ListView listView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
database = Room.databaseBuilder(getApplicationContext(), AbstractDatabase.class, "magazyn_db")
.allowMainThreadQueries().build();
binding = ActivityScrollingBinding.inflate(getLayoutInflater());
setContentView(binding.getRoot());
FloatingActionButton fab = binding.addCode;
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Log.println(Log.INFO, "VIEWs", "Showing popup");
PopupWindow codePopup;
View popupView = getLayoutInflater().inflate(R.layout.insert_code, binding.getRoot());
codePopup = new PopupWindow(popupView);
codePopup.setFocusable(true);
codePopup.setOutsideTouchable(true);
View cancelButton = codePopup.getContentView().findViewById(R.id.insert_cancel);
cancelButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
codePopup.dismiss();
}
});
View acceptButton = codePopup.getContentView().findViewById(R.id.insert_ok);
acceptButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
View editView = codePopup.getContentView().findViewById(R.id.insert_edit);
String id = ((EditText)editView).getText().toString().trim();
insertNewElement(id);
codePopup.dismiss();
}
});
}
});
[...]
For an unknown reason my popup doesn't go dismissed, both when I click outside of it, or press the cancel button (when I tried to print some logs from the handler, they worked). I have tried many solutions, also inflating it with no root, but then 'showAtPosition' doesn't even show it, and no solutions here on stackoverflow seem to help me even though there are many of them.
Is anyone able to point the problem here?
public void dismiss () Disposes of the popup window. This method can be invoked only after showAsDropDown(android.view.View) has been executed. Failing that, calling this method will have no effect.
I have an ExpandableListView whose children are a RelativeLayout of four LinearLayouts that contain TextViews which will pull answers to a question and assign that question a score from 1-4 (bad, mediocre, good, and world class respectively), and finally an EditText for the user to leave comments on why they rated the question that score. When the user clicks a score box, the background changes colour to highlight the selected score, and sets the other score box colours back to their default colour to show that they are no longer selected. Below is my Java to show how this works:
// ChildView views
badScoreView = convertView.findViewById(R.id.qwedit_main_badView);
mediocreScoreView = convertView.findViewById(R.id.qwedit_main_mediocreView);
goodScoreView = convertView.findViewById(R.id.qwedit_main_goodView);
worldclassScoreView = convertView.findViewById(R.id.qwedit_main_wcView);
badScoreTextView = (TextView) convertView.findViewById(R.id.qwedit_main_badTextView);
mediocreScoreTextView = (TextView) convertView.findViewById(R.id.qwedit_main_mediumTextView);
goodScoreTextView = (TextView) convertView.findViewById(R.id.qwedit_main_goodTextView);
worldClassScoreTextView = (TextView) convertView.findViewById(R.id.qwedit_main_worldclassTextView);
questionCommentEditText = (EditText) convertView.findViewById(R.id.qwedit_main_commentEditText);
// TODO: TextView score subcategory setters
badScoreView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO: add logic to change score
subCategoryScore = 1;
badScoreView.setBackgroundColor(Color.parseColor("#eca9a7"));
mediocreScoreView.setBackgroundColor(Color.parseColor("#f0ad4e"));
goodScoreView.setBackgroundColor(Color.parseColor("#5cb85c"));
worldclassScoreView.setBackgroundColor(Color.parseColor("#0275d8"));
questionCommentEditText.clearFocus();
}
});
mediocreScoreView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO: add logic to change score
subCategoryScore = 2;
badScoreView.setBackgroundColor(Color.parseColor("#d9534f"));
mediocreScoreView.setBackgroundColor(Color.parseColor("#f7d6a6"));
goodScoreView.setBackgroundColor(Color.parseColor("#5cb85c"));
worldclassScoreView.setBackgroundColor(Color.parseColor("#0275d8"));
questionCommentEditText.clearFocus();
}
});
goodScoreView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO: add logic to change score
subCategoryScore = 3;
badScoreView.setBackgroundColor(Color.parseColor("#d9534f"));
mediocreScoreView.setBackgroundColor(Color.parseColor("#f0ad4e"));
goodScoreView.setBackgroundColor(Color.parseColor("#addbad"));
worldclassScoreView.setBackgroundColor(Color.parseColor("#0275d8"));
questionCommentEditText.clearFocus();
}
});
worldclassScoreView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO: add logic to change score
subCategoryScore = 4;
badScoreView.setBackgroundColor(Color.parseColor("#d9534f"));
mediocreScoreView.setBackgroundColor(Color.parseColor("#f0ad4e"));
goodScoreView.setBackgroundColor(Color.parseColor("#5cb85c"));
worldclassScoreView.setBackgroundColor(Color.parseColor("#80baeb"));
questionCommentEditText.clearFocus();
}
});
And the layout, just in case that is relevant:
<?xml version="1.0" encoding="utf-8"?>

For some reason, when the user presses the EditText and either adds text or clicks out of it, the button onClick() functions no longer work (i.e., they no longer change colour).
Is this due to something with focus? the javacode onClick functions are in a CustomListViewAdapterin order to be able to inflate the same ExpandableListView for as many Questions as I will have (somewhere around 200 or so).
As far as I understood the problem is with the focus of the View. You might need to use an OnFocusChangeListener and then check if the focus event happened when the screen was in touch mode.
Or you could try to add these lines inside each onClick(View view) method:
view.setFocusableInTouchMode(true);
view.requestFocus();
view.setFocusableInTouchMode(false);
This way, view will get focus and you could do something inside the onClick() method after these lines of code, after the view was again set into setFocusableInTouchMode(false);
I wonder how to click a Button inside of AlertDialog in Android and this is my code
activity_float_info.xml
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Button"
android:id="#+id/button" />
MainActivity.java
QR_ = LayoutInflater.from(MainActivity.this).inflate(R.layout.activity_float_info, null);
MAIN_QR_SCAN = (LinearLayout) findViewById(R.id.MAIN_QR_SCAN);
MAIN_QR_SCAN.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
new AlertDialog.Builder(MainActivity.this)
.setCancelable(Boolean.TRUE)
.setNegativeButton(getString(R.string.CANCEL), new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int i) {
dialogInterface.dismiss();
}
})
.setView(R.layout.activity_float_info)
.show();
button = (Button)QR_.findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
button.setText("TEst");
}
});
}
});
I have inflate the layout..
I think the main problem is on
button = (Button)QR_.findViewById(R.id.button);
try this create a layout for dialog box
<TextView android:id="#+id/dialogtitle"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:textColor="#android:color/black"
android:text="Please enter the email address you used for the account"
/>
<EditText
android:id="#+id/emailedittext"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:ems="10"
android:padding="5dp"
android:cursorVisible="true"
android:singleLine="true"
android:background="#android:color/white"
android:textColor="#android:color/black"
android:hint="Enter Mail id"
android:textSize="20dp" >
<requestFocus />
</EditText>
<LinearLayout android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:weightSum="2"
android:orientation="horizontal">
<Button
android:id="#+id/cancelbtn"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="CANCEL"/>
<Button
android:id="#+id/okbtn"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="Ok"/>
</LinearLayout>
Then create a dialog box using this layout and handle button clicks
final Dialog dialog = new Dialog(MainActivity.this);
// Include dialog.xml file
dialog.setContentView(R.layout.forgotpassword);
// Set dialog title
dialog.setTitle("ALERT!!");
// set values for custom dialog components - text, image and button
Button okbtn = (Button) dialog.findViewById(R.id.okbtn);
Button cancelbtn = (Button) dialog.findViewById(R.id.cancelbtn);
final EditText emailedittext = (EditText) dialog.findViewById(R.id.emailedittext);
dialog.show();
dialog.getWindow().setSoftInputMode(
WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
// if decline button is clicked, close the custom dialog
cancelbtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Close dialog
dialog.dismiss();
}
});
okbtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String email=emailedittext.getText().toString();
//do something more here
}
});

Here is a hack to use AlertDialog:
public class CustomDialog extends AlertDialog {
protected CustomDialog(Context context) {
super(context);
}
}
And then in your Activity:
CustomDialog dialog = new CustomDialog(this);
View view = getLayoutInflater().inflate(R.layout.custom_dialog_layout,null);
dialog.setView(view);
Button button = (Button)view.findViewById(R.id.custom_button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(YourActivity.this,"Your message", Toast.LENGTH_LONG).show();
}
});
dialog.show();
And the layout of the dialog (which has nothing in it barring the Button):
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:id="#+id/custom_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="New Button" />
</RelativeLayout>
And you should be able to see a Toast when you click on the button. Hope this helps.
Dialog is like a popup window to show some options to users(options like accept/decline).
Using class android.app.Dialog to create dialog.
Using dialog.xml file to create custom dialog layout.
Example:
res/layout/dialog.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ImageView
android:id="#+id/imageDialog"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="6dp" />
<TextView
android:id="#+id/textDialog"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textColor="#FFF"
android:layout_toRightOf="#+id/imageDialog"/>
<Button
android:id="#+id/declineButton"
android:layout_width="100px"
android:layout_height="wrap_content"
android:text=" Submit "
android:layout_marginTop="5dp"
android:layout_marginRight="5dp"
android:layout_below="#+id/textDialog"
android:layout_toRightOf="#+id/imageDialog"
/>
</RelativeLayout>
Java Code
// Create custom dialog object
final Dialog dialog = new Dialog(CustomDialog.this);
// Include dialog.xml file
dialog.setContentView(R.layout.dialog);
// Set dialog title
dialog.setTitle("Custom Dialog");
// set values for custom dialog components - text, image and button
TextView text = (TextView) dialog.findViewById(R.id.textDialog);
text.setText("Custom dialog Android example.");
ImageView image = (ImageView) dialog.findViewById(R.id.imageDialog);
image.setImageResource(R.drawable.image0);
dialog.show();
Button declineButton = (Button) dialog.findViewById(R.id.declineButton);
// if decline button is clicked, close the custom dialog
declineButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// Close dialog
dialog.dismiss();
}
});
So my layout is still visible, maybe someone sees mistake? I want to dispear it when infoButton(imagebutton) is clicked.
FrameLayout infolayout;
infolayout = (FrameLayout) findViewById(R.id.infoLayout);
public void infoPressed(View v){//info button is pressed by user
//infoLayout.setVisibility(View.GONE);
infolayout.setVisibility(View.INVISIBLE);
}
<FrameLayout
android:layout_width="193dp"
android:layout_height="200dp"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignBottom="#+id/serviceLayout"
android:id="#+id/infoLayout">
I wacthed: How to change visibility of layout programaticly
EDITED:
wrong code part, still not working for me
*Try this**
<RelativeLayout

MainActivity.java
public class MainActivity extends Activity
{
FrameLayout infolayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
infolayout = (FrameLayout) findViewById(R.id.serviceLayout);
}
public void infoPressed(View v){ //info button is pressed by user
//infoLayout.setVisibility(View.GONE);
infolayout.setVisibility(View.INVISIBLE);
}
}
if your ID declaration is correct I guess you have to change the line
infolayout.setVisibility(View.INVISIBLE);
to
infolayout.setVisibility(FrameLayout.INVISIBLE);
I am making a game that requires multiple views within an Activity, and i decided to use Viewflipper to do.
The thing is. I need to have 3 views in in the viewflipper, and the LAST view will transfer back to the first one.
My problem is that the buttons are acting weird, and they are either not going to the next, or skipping the third view. I tried to put vf.setDisplayedChild(R.Id.gamescreen1); at the last view but then the whole thing breaks down.
Thanks for all answers in advance, i have been stuck with this problem for DAYS! and yes, i know that i am a noob :(

try this
flipper.setDisplayedChild(1);
.
.to
.
flipper.setDisplayedChild(3);
if(flipper.getCurrentView() == 3)
{
flipper.setDisplayedChild(1);
}
setDisplayChild takes an integer parameter that is the zero based index of the child to display NOT the id of the child to display. A bit confusing I know.
