Display an image in AlertDialog
In this blog post, I would like to explain how to display an image in AlertDialog box in Android.
First, create a activity_main.xml XML file, and add the following code:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" > <Button android:id = "@+id/button" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:gravity="center"> </Button> </LinearLayout>
Then, create a dialog_main.xml, and add folowing code:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" > <TextView android:id="@+id/textView" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/hello_world" /> <ImageView android:id="@+id/imageView" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout>
Now, create a MainActivity.class Java file, and add following code:
package com.example.aletdialog; import android.app.Activity; import android.app.AlertDialog; import android.content.DialogInterface; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import android.view.View.OnClickListener; import android.view.ViewGroup; import android.widget.Button; import android.widget.ImageView; import android.widget.TextView; public class MainActivity extends Activity { AlertDialog alert; Button button; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); button = (Button) findViewById(R.id.button); button.setText("Click to get a DialogBox"); button.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub alert(); } }); } public void alert(){ // TODO Auto-generated method stub AlertDialog.Builder alertadd = new AlertDialog.Builder( MainActivity.this); alertadd.setTitle("Android"); LayoutInflater factory = LayoutInflater.from(MainActivity.this); final View view = factory.inflate(R.layout.dialog_main, null); ImageView image= (ImageView) view.findViewById(R.id.imageView); image.setImageResource(R.drawable.ic_launcher); TextView text= (TextView) view.findViewById(R.id.textView); text.setText("Android"); alertadd.setView(view); alertadd.setNeutralButton("ok", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dlg, int sumthin) { } }); alertadd.show(); } }
