【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);
