I must cautiously doubt the previously accepted answer that using a DialogFragment is the best option. The intended (primary) purpose of the DialogFragment seems to be to display fragments that are dialogs themselves, not to display fragments that have dialogs to display. I believe that using the fragment’s activity to mediate between the dialog and … Read more
In order to have a dialog activity shown over another application, a few things must be done: The dialog activity must have a translucent theme, to allow the other application to show up behind it (see @android:style/Theme.Translucent.NoTitleBar) The dialog activity must not fill the screen, for the same reason (see Window.setLayout) The dialog activity must … Read more
Background The Activity behind an Acivity is drawn if the foreground activity’s theme according to its AndroidManifest.xml is a dialog; otherwise the android os will not draw the Activity behind it (probably to save memory since it usually won’t be seen anyway). To exploit this, we set the theme of our Acitvity to a dialog … Read more
Dialog creation: AlertDialog.Builder builder = new AlertDialog.Builder(YourActivity.this); builder.setCancelable(false) .setMessage(“Please Enter data”) .setView(edtLayout) //<– layout containing EditText .setPositiveButton(“Enter”, new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { //All of the fun happens inside the CustomListener now. //I had to move it to enable data validation. } }); AlertDialog alertDialog = builder.create(); alertDialog.show(); Button theButton = … Read more
When dialog.setCanceledOnTouchOutside(true); then you just override onCancel() like this: dialog.setOnCancelListener( new DialogInterface.OnCancelListener() { @Override public void onCancel(DialogInterface dialog) { //When you touch outside of dialog bounds, //the dialog gets canceled and this method executes. } } ); Type your code inside the onCancel() method so it runs when the dialog gets canceled.
Create an XML file in drawable, say dialog_bg.xml: <?xml version=”1.0″ encoding=”utf-8″?> <shape xmlns:android=”http://schemas.android.com/apk/res/android”> <solid android:color=”@color/white”/> <corners android:radius=”30dp” /> <padding android:left=”10dp” android:top=”10dp” android:right=”10dp” android:bottom=”10dp” /> </shape> set it as the background in your layout XML: android:background=”@drawable/dialog_bg” Set the background of the dialog’s root view to transparent, because Android puts your dialog layout within a root view … Read more
Calling findViewById() will search for views within your Activity’s layout and not your dialog’s view. You need to call findViewById() on the specific View that you set as your dialog’s layout. Try this private void initSearch() { AlertDialog.Builder searchDialog = new AlertDialog.Builder(this); LayoutInflater inflater = this.getLayoutInflater(); searchDialog.setTitle(“Search Photos”); searchDialog.setMessage(“Specify tag and value…”); // R.layout.search_dialog is … Read more
The comment of Aleks G (below the question) points in the right direction. The appearance of the dialog is defined by a separate style (android:alertDialogStyle). But one cannot apply the style directly to a ProgressDialog. Now, how do I get that yellow background? Step 1: Define a theme that inherits from Theme.Dialog: <style name=”MyTheme” parent=”@android:style/Theme.Dialog”> … Read more
I’m guessing – are you trying to create Dialog with an application context? Something like this: new Dialog(getApplicationContext()); This is wrong. You need to use an Activity context. You have to try like: new Dialog(YourActivity.this);
I have made a small demo of NumberPicker. This may not be perfect but you can use and modify the same. public class MainActivity extends Activity implements NumberPicker.OnValueChangeListener { private static TextView tv; static Dialog d ; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); tv = (TextView) findViewById(R.id.textView1); Button b = (Button) findViewById(R.id.button11); b.setOnClickListener(new … Read more
