0
03:57
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>
