Оле*_*дев -1 android image screen seconds android-layout
我正在制作一个应用程序,我正在使用sqlite数据库.在第一次启动我的应用程序和onUpdate时,我将从xml文件向sqlite db添加数据.因此,在我的应用程序的第一次启动时,它显示我白屏约15秒.我想要显示我的全屏幕,约15秒.我怎么能这样做?
您可以使用SplashActivity显示图像,用于Hander.postDelayed()在startActivity到主屏幕之前将此屏幕延迟15秒.
这是一个例子:
public class Splash extends Activity {
/** Duration of wait **/
private final int SPLASH_DISPLAY_LENGTH = 15000;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.splashscreen);
/* New Handler to start the Menu-Activity
* and close this Splash-Screen after some seconds.*/
//Load data
new Handler().postDelayed(new Runnable(){
@Override
public void run() {
/* Create an Intent that will start the Menu-Activity. */
Intent mainIntent = new Intent(Splash.this,MainActivity.class);
Splash.this.startActivity(mainIntent);
Splash.this.finish();
}
}, SPLASH_DISPLAY_LENGTH);
}
}
