在应用程序中经常用到启动画面,会启动一个后台线程为主程序的运行准备资源。
Android要实现启动画面可以这样做:
这是splash.xml布局文件的代码
代码语言:javascript复制代码< LinearLayout
xmlns:android ="http://schemas.android.com/apk/res/android"
android:layout_height ="fill_parent" android:layout_width ="fill_parent" android:orientation ="vertical" >
< ImageView android:layout_height ="fill_parent" android:layout_width ="fill_parent" android:scaleType ="fitCenter" android:src ="@drawable/splash" ></ ImageView >
</ LinearLayout >
放一个ImageView加载启动画面图片
SplashActivity作为主视图启动
代码语言:javascript复制代码/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super .onCreate(savedInstanceState);
setContentView(R.layout.splash);
Handler x = new Handler();
x.postDelayed( new splashhandler(), 2000 );
}
class splashhandler implements Runnable{
public void run() {
startActivity( new Intent(getApplication(),MainActivity. class ));
SplashActivity. this .finish();
}

加载后使用Handler的postDelayed方法,2秒后执行跳转到主视图。
