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[code]<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>[/code]
放一个ImageView加载启动画面图片
SplashActivity作为主视图启动/** 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();
}
}
