Android中转场动画的使用

activity_main.xml

<LinearLayout 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"
android:orientation="vertical"
tools:context="${relativePackage}.${activityClass}" >

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Activity_ONE" />

<Button
android:onClick="btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="转到第二个Activity" />

</LinearLayout>

activity_two.xml

<LinearLayout 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"
android:orientation="vertical"
tools:context="${relativePackage}.${activityClass}" >

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Activity_TWO" />

<Button
android:onClick="btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="转到第一个Activity" />

</LinearLayout>

在\res\anim目录下写动画
left_in.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

<translate
android:duration="500"
android:fromXDelta="-100.0%p"
android:toXDelta="0" />

<alpha
android:duration="500"
android:fromAlpha="0"
android:toAlpha="1" />

</set>

left_out.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

<translate
android:duration="500"
android:fromXDelta="0.0"
android:toXDelta="-100.0%p" />

<alpha
android:duration="500"
android:fromAlpha="1"
android:toAlpha="0" />

</set>

right_in.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

<translate
android:duration="500"
android:fromXDelta="100.0%p"
android:toXDelta="0.0" />
<!-- 透明 0是完全透明 1是不透明 -->
<alpha
android:duration="500"
android:fromAlpha="0"
android:toAlpha="1" />

</set>

right_out.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >

<translate
android:duration="500"
android:fromXDelta="0.0"
android:toXDelta="100.0%p" />

<alpha
android:duration="500"
android:fromAlpha="1"
android:toAlpha="0" />

</set>

MainActivity.java

package cn.wuxiaocheng.anim;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

}
public void btn(View v) {
Intent intent = new Intent(MainActivity.this, TwoActivity.class);
startActivity(intent);
finish();
overridePendingTransition(R.anim.right_in, R.anim.left_out);
}
}

TwoActivity.java

package cn.wuxiaocheng.anim;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;

public class TwoActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_two);
}

public void btn(View v) {
Intent intent = new Intent(TwoActivity.this, MainActivity.class);
startActivity(intent);
overridePendingTransition(R.anim.left_in, R.anim.right_out);
finish();
}
}

别忘了在清单文件中添加activity

AndroidManifest.xml

<activity
android:name=".TwoActivity" >
</activity>
