You cannot do it with default Dialog. But obviously, you can start with your own layout on the dialog.
Custom AlertDialog
This full example includes passing data back to the Activity.
Create a custom layout
A layout with an EditText is used for this simple example, but you can replace it with anything you like.
custom_layout.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:paddingLeft="20dp" android:paddingRight="20dp" android:layout_width="match_parent" android:layout_height="match_parent"> <EditText android:id="@+id/editText" android:layout_width="match_parent" android:layout_height="wrap_content"/> </LinearLayout>
Use the dialog in code
The key parts are
- using
setView to assign the custom layout to the AlertDialog.Builder - sending any data back to the activity when a dialog button is clicked.
This is the full code from the example project shown in the image above:
MainActivity.java
public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); } public void showAlertDialogButtonClicked(View view) { // create an alert builder AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setTitle("Name"); // set the custom layout final View customLayout = getLayoutInflater().inflate(R.layout.custom_layout, null); builder.setView(customLayout); // add a button builder.setPositiveButton("OK", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, int which) { // send data from the AlertDialog to the Activity EditText editText = customLayout.findViewById(R.id.editText); sendDialogDataToActivity(editText.getText().toString()); } }); // create and show the alert dialog AlertDialog dialog = builder.create(); dialog.show(); } // do something with the data coming from the AlertDialog private void sendDialogDataToActivity(String data) { Toast.makeText(this, data, Toast.LENGTH_SHORT).show(); } }
Notes
- If you find yourself using this in multiple places, then consider making a
DialogFragment subclass as is described in the documentation.
