This example demonstrate about How to add custom view in alert dialog
Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.
Step 2 − Add the following code to res/layout/activity_main.xml.
<?xml version = "1.0" encoding = "utf-8"?> <LinearLayout xmlns:android = "https://schemas.android.com/apk/res/android" android:layout_width = "match_parent" android:gravity = "center" android:layout_height = "match_parent"> <TextView android:id = "@+id/click" android:layout_width = "wrap_content" android:textSize = "30sp" android:layout_height = "wrap_content" android:text = "Click"/> </LinearLayout>
In the above code, we have taken text view.
Step 3 − Add the following code to src/MainActivity.java
package com.example.myapplication; import android.annotation.TargetApi; import android.content.DialogInterface; import android.os.Build; import android.os.Bundle; import android.support.v7.app.AlertDialog; import android.support.v7.app.AppCompatActivity; import android.view.View; import android.widget.EditText; import android.widget.Switch; import android.widget.TextView; import android.widget.Toast; public class MainActivity extends AppCompatActivity { TextView text; @TargetApi(Build.VERSION_CODES.LOLLIPOP) @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); text = findViewById(R.id.click); text.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { showAlertDialog(); } }); } private void showAlertDialog() { AlertDialog.Builder alertDialog = new AlertDialog.Builder(MainActivity.this); final View customLayout = getLayoutInflater().inflate(R.layout.custom, null); alertDialog.setView(customLayout); alertDialog.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); Toast.makeText(MainActivity.this,editText.getText().toString(),Toast.LENGTH_LONG).show(); } }); AlertDialog alert = alertDialog.create(); alert.setCanceledOnTouchOutside(false); alert.show(); } }
