Splash闪屏页的使用方法
方法一（静态）：使用Handler，在handleMessage中使用Intent实现跳转
MainActivity
package com.example.forherplayer;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
public class SplashActivity extends Activity {
private static final int START_ACTIVITY = 0x1;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
handler.sendEmptyMessageDelayed(START_ACTIVITY, 3000);
}
private Handler handler = new Handler(){
public void handleMessage(Message msg) {
switch(msg.what){
case START_ACTIVITY:
startActivity(new Intent(SplashActivity.this,MainActivity.class));
finish();
break;
}
};
};
}
其他代码与下文相同，详见方法二
方法二（动态）：使用AlphaAnimation，在监听最后结束动画后实现Intent跳转
MainActivity
package com.example.splashtestdemo;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.view.animation.AlphaAnimation;
import android.view.animation.Animation;
import android.view.animation.Animation.AnimationListener;
import android.widget.ImageView;
/*

*/
//public class SplashActivity extends Activity {
//
// private static final int START_ACTIVITY = 0x1;
// @Override
// protected void onCreate(Bundle savedInstanceState) {
// super.onCreate(savedInstanceState);
// setContentView(R.layout.activity_splash);
// handler.sendEmptyMessageDelayed(START_ACTIVITY, 3000);
// }
//
//
// private Handler handler = new Handler(){
// public void handleMessage(Message msg) {
// switch(msg.what){
// case START_ACTIVITY:
// startActivity(new Intent(SplashActivity.this,MainActivity.class));
// finish();
// break;
// }
// };
// };
//}
/*

*/
public class SplashActivity extends Activity {
private ImageView iv_splash;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//添加去标题和隐藏状态栏代码，测试时发现标题与状态栏瞬间状态可视，建议在清单文件SplashActivity的them添加为
//android:theme="@android:style/Theme.Translucent.NoTitleBar.Fullscreen"
// //去标题
// requestWindowFeature(Window.FEATURE_NO_TITLE);
// //隐藏状态栏
// getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_splash);
iv_splash = (ImageView) findViewById(R.id.iv_splash);
//设置透明度动画由10%到100%
AlphaAnimation alphaAnimation = new AlphaAnimation(0.1f, 1.0f);
//设置动画时长3秒
alphaAnimation.setDuration(3000);
//开始动画
iv_splash.startAnimation(alphaAnimation);
//为动画设置监听器
alphaAnimation.setAnimationListener(new AnimationListener() {
@Override
public void onAnimationStart(Animation animation) {
// TODO Auto-generated method stub
}
@Override
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub
}
@Override
public void onAnimationEnd(Animation animation) {
// TODO Auto-generated method stub
startActivity(new Intent(SplashActivity.this,MainActivity.class));
finish();
}
});
}
}

由于没有找到合适手机gif截屏app，所以不上传效果图了，然而闪屏页素材还是可以上传的
