Android实现应用过渡动画（附源码）

一、BaseActivity继承类

package com.favccxx.favdemo.base;

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

public class BaseActivity extends Activity {
	
	private static final String TAG = "BaseActivity";

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		android.util.Log.i(TAG, this.getClass().getSimpleName() + "onCreate Method is invoked!");
		super.onCreate(savedInstanceState);
		requestWindowFeature(Window.FEATURE_NO_TITLE);
	}

	@Override
	protected void onDestroy() {
		// TODO Auto-generated method stub
		super.onDestroy();
	}

	@Override
	protected void onPause() {
		// TODO Auto-generated method stub
		super.onPause();
	}

	@Override
	protected void onPostResume() {
		// TODO Auto-generated method stub
		super.onPostResume();
	}

	@Override
	protected void onRestart() {
		// TODO Auto-generated method stub
		super.onRestart();
	}

	@Override
	protected void onRestoreInstanceState(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onRestoreInstanceState(savedInstanceState);
	}

	@Override
	protected void onResume() {
		// TODO Auto-generated method stub
		super.onResume();
	}

	@Override
	protected void onStart() {
		// TODO Auto-generated method stub
		super.onStart();
	}

	@Override
	protected void onStop() {
		// TODO Auto-generated method stub
		super.onStop();
	}
	
	protected void openActivity(Class<?> pClass) {
		openActivity(pClass, null);
	}

	protected void openActivity(Class<?> pClass, Bundle pBundle) {
		Intent intent = new Intent(this, pClass);
		if (pBundle != null) {
			intent.putExtras(pBundle);
		}
		startActivity(intent);
	}

	protected void openActivity(String pAction) {
		openActivity(pAction, null);
	}

	protected void openActivity(String pAction, Bundle pBundle) {
		Intent intent = new Intent(pAction);
		if (pBundle != null) {
			intent.putExtras(pBundle);
		}
		startActivity(intent);
	}
	
	

}

二、SplashActivity

package com.favccxx.favdemo.ui;

import android.os.Bundle;
import android.os.Handler;
import android.view.View;
import android.view.animation.Animation;
import android.view.animation.Animation.AnimationListener;
import android.view.animation.AnimationUtils;

import com.favccxx.favdemo.MainActivity;
import com.favccxx.favdemo.R;
import com.favccxx.favdemo.base.BaseActivity;

public class SplashActivity extends BaseActivity {
	
	private Handler handler = new Handler();

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		View view = View.inflate(this, R.layout.activity_start, null);
		setContentView(view);
		Animation animation = AnimationUtils.loadAnimation(this, R.anim.alpha); 
		view.startAnimation(animation);
		animation.setAnimationListener(new AnimationListener() {
			
			@Override
			public void onAnimationStart(Animation arg0) {
				
			}
			
			@Override
			public void onAnimationRepeat(Animation arg0) {
				
			}
			
			@Override
			public void onAnimationEnd(Animation arg0) {
				handler.postDelayed(new Runnable() {
					
					@Override
					public void run() {
						goBack();
					}
				}, 500);
				
			}
		});
	}

	@Override
	protected void onResume() {
		super.onResume();
	}
	
	private void goBack(){
		openActivity(MainActivity.class);
		finish();
	}
	

}

三、activity_start.xml

<?xml version="1.0" encoding="UTF-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/splash_load">
</RelativeLayout>

四、AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.favccxx.favdemo"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="14"
        android:targetSdkVersion="19" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.favccxx.favdemo.ui.SplashActivity"
            android:label="@string/app_name"
			android:launchMode="singleTask"
			android:screenOrientation="portrait">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity 
            android:name="com.favccxx.favdemo.MainActivity"
            android:label="@string/app_name"
            android:launchMode="singleTask"
            android:screenOrientation="portrait"></activity>
    </application>

</manifest>
