【Android】Activity之间的动画切换

不多说，直接上代码，第一个Activity：

package com.example.activityanimation;

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

public class MainActivity extends Activity {
Button button;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

button = (Button)findViewById(R.id.button1);
button.setOnClickListener(new Button.OnClickListener(){
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent();
intent.setClass(MainActivity.this, TestActivity.class);
MainActivity.this.finish();
startActivity(intent);
overridePendingTransition(R.anim.push_left_in, R.anim.push_left_out);
}
});
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}

第二个Activity：

package com.example.activityanimation;

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

public class TestActivity extends Activity {
Button button;

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test);

button = (Button)findViewById(R.id.button2);
button.setOnClickListener(new Button.OnClickListener(){
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent intent = new Intent();
intent.setClass(TestActivity.this, MainActivity.class);
TestActivity.this.finish();
startActivity(intent);
overridePendingTransition(R.anim.push_right_in, R.anim.push_right_out);
}
});
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_test, menu);
return true;
}
}

两个界面分别如下：





四个动画文件，位于（res/anim）下面：

1)push_left_in.xml:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:fromXDelta="100%p"
android:toXDelta="0"
android:duration="1000" />
<alpha
android:fromAlpha="0.1"
android:toAlpha="1.0"
android:duration="1000" />

<scale
android:fromXScale="2.0"
android:toXScale="1.0"
android:fromYScale="2.0"
android:toYScale="1.0"
android:pivotX="50%p"
android:pivotY="50%p"
android:duration="1000"
/>
</set>

2)push_left_out.xml:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:fromXDelta="0"
android:toXDelta="-100%p"
android:duration="1000" />
<alpha
android:fromAlpha="1.0"
android:toAlpha="0.1"
android:duration="1000" />

<scale
android:fromXScale="1.0"
android:toXScale="2.0"
android:fromYScale="1.0"
android:toYScale="2.0"
android:pivotX="50%p"
android:pivotY="50%p"
android:duration="1000"
/>
</set>

3)push_right_in.xml:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:fromXDelta="-100%p"
android:toXDelta="0"
android:duration="1000" />
<alpha
android:fromAlpha="0.1"
android:toAlpha="1.0"
android:duration="1000" />

<scale
android:fromXScale="2.0"
android:toXScale="1.0"
android:fromYScale="2.0"
android:toYScale="1.0"
android:pivotX="50%p"
android:pivotY="50%p"
android:duration="1000"
/>
</set>

4)push_right_out.xml:

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:fromXDelta="0"
android:toXDelta="100%p"
android:duration="1000" />
<alpha
android:fromAlpha="1.0"
android:toAlpha="0.1"
android:duration="1000" />

<scale
android:fromXScale="1.0"
android:toXScale="2.0"
android:fromYScale="1.0"
android:toYScale="2.0"
android:pivotX="50%p"
android:pivotY="50%p"
android:duration="1000"
/>
</set>

注：调用通过以下一行代码实现：

overridePendingTransition(R.anim.push_left_in, R.anim.push_left_out);
