Dialog Animation using windowAnimations

In this exercise, we are going to apply slide-in and slide-out animation on dialog, using windowAnimations.

Create/modify /res/values/styles.xml to add animation style of DialogAnimation, using build-in animation of slide_in_left and slide_out_right.

<resources>    <style name="AppTheme" parent="android:Theme.Light" />    <style name="DialogAnimation">        <item name="android:windowEnterAnimation">@android:anim/slide_in_left</item>        <item name="android:windowExitAnimation">@android:anim/slide_out_right</item>    </style></resources>

Implement our dialog layout, /res/layout/dialoglayout.xml.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="fill_parent"    android:layout_height="fill_parent"     android:orientation="vertical">    <ImageView        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:src="@drawable/ic_launcher"/>    <Button        android:id="@+id/dismiss"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="dismiss"/></LinearLayout>

MainActivity.java

package com.example.animationdialog;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.app.Activity;import android.app.Dialog;public class MainActivity extends Activity { Button btnOpenDialog;     @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        btnOpenDialog = (Button)findViewById(R.id.opendialog);        btnOpenDialog.setOnClickListener(new OnClickListener(){   @Override   public void onClick(View v) {    openDialog();   }});    }    private void openDialog(){     final Dialog dialog = new Dialog(MainActivity.this);     dialog.setTitle("Animation Dialog");     dialog.setContentView(R.layout.dialoglayout);     dialog.getWindow().getAttributes().windowAnimations = R.style.DialogAnimation;     Button btnDismiss = (Button)dialog.getWindow().findViewById(R.id.dismiss);          btnDismiss.setOnClickListener(new OnClickListener(){   @Override   public void onClick(View v) {    dialog.dismiss();   }});          dialog.show();    }    }

Main layout:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent" >    <Button        android:id="@+id/opendialog"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_centerHorizontal="true"        android:layout_centerVertical="true"        android:padding="@dimen/padding_medium"        android:text="Open Dialog"        tools:context=".MainActivity" /></RelativeLayout>
