2013-9-26 开机等待的Activity

第一步：Activity 类

public class AdvertActivity extends Activity{
private Handler myHandler = new Handler() {
public void handleMessage(android.os.Message msg) {
final Intent intent = new Intent(AdvertActivity.this,HomeActivity.class);
AdvertActivity.this.startActivity(intent);
AdvertActivity.this.finish();
};
};

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_welcome);
myHandler.sendEmptyMessageDelayed(0, 3000);  //时间3s后跳转到HomeActivity
}
}

第二步：layout 里面xml代码

<RelativeLayout 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"
    tools:context=".WelcomeActivity" 
    android:background="@drawable/advertisement">
</RelativeLayout>
