I am trying to display a dialog box when a particular item is clicked, but I can only see a little box in place of the layout I have set. here is the onbindview holder.
#Override
public void onBindViewHolder(ListEventAdapter.ListEventViewHolder holder, int position) {
EventResponse event = eventList.get(position);
view to be clicked
holder.home_view.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
showAlertDialog(view);
}
});
private void showAlertDialog(View view) {
Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.alert_dialog);
home_t = dialog.findViewById(R.id.home_t);
place_btn = (CircularProgressButton) dialog.findViewById(R.id.place_bet_btn);
close = dialog.findViewById(R.id.close);
close.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dialog.cancel();
}
});
place_btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
dialog.dismiss();
}
});
dialog.show();
}
on R.layout.alert_dialog just use match_parent in layout_width

I want to create a Bottom Sheet Dialog. It looks like the image below
enter image description here
public class MainActivity extends AppCompatActivity {
//this is Button that open dialog
private Button button;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button = findViewById(R.id.nextBtn);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
BottomSheetDialog bottomSheetDialog = new BottomSheetDialog(
MainActivity.this, R.style.BottomSheetDialogTheme);
View bottomSheetView = LayoutInflater.from(getApplicationContext())
.inflate(R.layout.layout_bottom_sheet, (LinearLayout) findViewById(R.id.bottomSheetContainer));
bottomSheetDialog.setContentView(bottomSheetView);
bottomSheetView.findViewById(R.id.doNotAgree).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
System.exit(0);
}
});
bottomSheetView.findViewById(R.id.agree).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
startActivity(new Intent(MainActivity.this, Activity2.class));
finish();
}
});
}
});
}
}
I have tried many methods such as SharedPreferences. But it not working
SharedPreferences preference = getSharedPreferences("mPreference", MODE_PRIVATE);
boolean isUserAgreed = preference.getBoolean("isUserAgreed", false);
if (!isUserAgreed){
// show bottomSheetDialog
} else {
startActivity(new Intent(MainActivity.this, Activity2.class));
finish();
}
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
BottomSheetDialog bottomSheetDialog = new BottomSheetDialog(
MainActivity.this, R.style.BottomSheetDialogTheme);
View bottomSheetView = LayoutInflater.from(getApplicationContext())
.inflate(R.layout.layout_bottom_sheet, (LinearLayout) findViewById(R.id.bottomSheetContainer));
bottomSheetDialog.setContentView(bottomSheetView);
bottomSheetView.findViewById(R.id.doNotAgree).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
System.exit(0);
}
});
bottomSheetView.findViewById(R.id.agree).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
SharedPreferences.Editor editor = getSharedPreferences("mPreference", MODE_PRIVATE).edit();
editor.putBoolean("isUserAgreed", true);
editor.apply();
startActivity(new Intent(MainActivity.this, Activity2.class));
finish();
}
});
}
});
I am trying to change the text of button inside onClick() but it's not changing. I have tried the following -
viewHoder.btn_select_qq.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
viewHoder.btn_select.setText("xxxxx");
notifyDataSetChanged();
}
});
How to set it?
Try this -
viewHoder.btn_select_qq.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Button b = (Button) v;
b.setText("xxxxx");
}
});
I would like to display images that are stored in an arraylist to an imageview.I am using picasso library to store the links.When i press the button next i want the picture to change to the next image.I am using a for loop but i get only the last element.Here is the code:
ImageView image1;
Button bNext,
ArrayList<String>ll=new ArrayList<>();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_fwtografies);
image1=(ImageView)findViewById(R.id.image1);
bNext=(Button)findViewById(R.id.bNext);
ll.add("http://i.imgur.com/QoUeA2I.jpg");
ll.add("http://i.imgur.com/21szRz9.jpg");
ll.add("https://upload.wikimedia.org/wikipedia/en/e/ec/Clip_Poster.jpg");
bBack.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Intent fwtografiesActivityIntent = new Intent(Fwtografies.this,MainActivity.class);
Fwtografies.this.startActivity(fwtografiesActivityIntent);
}
});
bNext.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
for(int i=0;i<ll.size();i++){
sp(ll.get(i),image1);
}
}
});
bPrevius.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
viewFlipper.showPrevious();
}
});
sp("http://i.imgur.com/gijIKJO.jpg",image1);
//sp("http://i.imgur.com/QoUeA2I.jpg",image2);
//sp("http://i.imgur.com/21szRz9.jpg",image3);
}
public void sp(String a,ImageView b){
Picasso
.with(getApplicationContext())
.load(a)
.into(b);
}}
Everytime you click on Button "bnext" you are going through your whole for-loop and therefore only the last element of your list gets shown. Try:
int i = 0;
bNext.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if(i<ll.size()){
sp(ll.get(i),image1);
i++;
}
}
});
My mistake is that i used for loop where i should use if statment.
This code works for my case:
int i=0; bNext.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//viewFlipper.showNext();
if(i<ll.size()){
sp(ll.get(i),image1);
i++;
}`
Im a Beginner in Java and Android Studio. With this Code I try to change the layout in this activity. The current layout is "marcelscorpion_1".
Only the Buttons "weiter_1" and "zurück_1" are working and I don't know why...
public void SwitchLayout()
{
Button weiter_1 = (Button) findViewById(R.id.marcelscorpion_weiter1);
Button zurück_1 = (Button) findViewById(R.id.marcelscorpion_zurück1);
View marcelscorpion_2 = LayoutInflater.from(getApplication()).inflate(R.layout.marcelscorpion_2, null);
Button weiter_2 = (Button) marcelscorpion_2.findViewById(R.id.marcelscorpion_weiter2);
Button zurück_2 = (Button) marcelscorpion_2.findViewById(R.id.marcelscorpion_zurück2);
View marcelscorpion_3 = LayoutInflater.from(getApplication()).inflate(R.layout.marcelscorpion_3, null);
Button weiter_3 = (Button) marcelscorpion_3.findViewById(R.id.marcelscorpion_weiter3);
Button zurück_3 = (Button) marcelscorpion_3.findViewById(R.id.marcelscorpion_zurück3);
weiter_1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
setContentView(R.layout.marcelscorpion_2);
}
});
weiter_2.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
setContentView(R.layout.marcelscorpion_3);
}
});
weiter_3.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
setContentView(R.layout.marcelscorpion_1);
}
});
zurück_1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
setContentView(R.layout.marcelscorpion_3);
}
});
zurück_2.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
setContentView(R.layout.marcelscorpion_1);
}
});
zurück_3.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
setContentView(R.layout.marcelscorpion_2);
}
});
}
Need Help ;) Thank you!
Every time you call setContentView() you should find and setOnClickListener(..) again to all buttons contained in the new layout.
A better way is define onclick attribute in the layouts xml file.
For instance if you have this:
<Button
android:id="#+id/w2"
android:onClick="getms3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="w2" />
then you should define
public void getms3(View v)
{
setContentView(R.layout.ms3);
}
Just add your buttons of that layout when you are doing setContentView() in onClick() methods like this :
weiter_1.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
setContentView(R.layout.marcelscorpion_2);
Button weiter_2 = (Button) marcelscorpion_2.findViewById(R.id.marcelscorpion_weiter2);
Button zurück_2 = (Button) marcelscorpion_2.findViewById(R.id.marcelscorpion_zurück2);
}
});
I have a MainActivity like this one below:
My question is how to open a DialogFragment clicking on the TextView "click HERE to give a name to the task" placed next to "play" button.
Here is the code of my TextView:
TextView buttonView = new TextView(this);
buttonView.setHint("click HERE to give a name to the task");
buttonView.setX(50);
buttonView.setY(50);
and the code of the DialogFragent:
public class ButtonNameDialogFragment extends DialogFragment {
private IFragment iButNamFrag;
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder setButNameAlert = new AlertDialog.Builder(getActivity());
setButNameAlert.setTitle("Set Task name");
LayoutInflater inflater = getActivity().getLayoutInflater();
setButNameAlert.setView(inflater.inflate(R.layout.button_name_fragment, null))
.setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// TODO Implement dialogPositiveClick
}
})
.setNegativeButton(R.string.undo, new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
// TODO Implement dialogNegativeClick
}
});
return setButNameAlert.create();
}
#Override
public void onAttach(Activity activity) {
super.onAttach(activity);
iButNamFrag = (IFragment) activity;
}
}
and here is the interface:
public interface IFragment {
public void onDialogPositiveClick(DialogFragment dialog);
public void onDialogNegativeClick(DialogFragment dialog);
}
You can set an onClickListener to any view in Android and then perform any behavior you would like
buttonView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Create new DiaglogFragment and display it
}
};
This is the same method used for any kind of button pressing. There are plenty of other answers already out on StackOverflow with further examples of this. If you need more information on tap recognition or displaying fragments, a quick search will find it on Stack.
buttonView.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
DialogFragment frag = new ButtonNameDialogFragment();
frag.show(*context*, ButtonNameDialogFragment.class.getCanonicalName());
}
});
