推荐答案

您可以使用以下code吧。

You can use the following code for it.

public class Splash extends Activity {
/** Called when the activity is first created. */

private boolean mSplashActive = true, mPaused;
private long mSplashTime = 1000;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.splash);

    new Thread(){
        public void run(){
            try {
                long ms = 0;
                while(mSplashActive && ms < mSplashTime) {
                    sleep(100);
                    if(!mPaused) {
                        ms += 100;
                    }
                }
                if(Resources.getResources().isUserRegistered(Splash.this)) {
                    //user is registered so launch main screen
                } else {
                    //user is not registered launch welcome wizard.
                    Intent intent = new Intent(Splash.this, WelcomeScreen.class);
                    Splash.this.startActivity(intent);
                }
                finish();
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }.start();

}

@Override
public void onPause(){
    super.onPause();
    mPaused = true;
}

@Override
public void onResume(){
    super.onResume();
    mPaused = false;
}

@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
    super.onKeyDown(keyCode, event);

    if(keyCode == KeyEvent.KEYCODE_DPAD_CENTER) {
        mSplashActive = false;
    }
    return true;
}
}
