    };

    mSplashThread.start();        
  }

  /**
   * Processes splash screen touch events
   */
  @Override
  public boolean onTouchEvent(MotionEvent evt)
  {
    if(evt.getAction() == MotionEvent.ACTION_DOWN)
    {
        synchronized(mSplashThread){
            mSplashThread.notifyAll();
        }
    }
    return true;
  }    
} 

这段代码有什么问题?单击时,它崩溃了。此外,下一个活动不会在此活动结束后开始。这是用于显示闪屏的活动。

只需删除stop()方法即可

我更喜欢使用 Runnable 元素而不是 Thread。我的以下活动的启动代码运行良好。我希望它可以帮助你:

public class SplashScreenActivity extends Activity implements OnTouchListener {

    private int SPLASH_DISPLAY_LENGTH = 3000;

    private Handler splashHandler;
    private Runnable splashRunnable;

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

        findViewById(R.id.splash_img).setOnTouchListener(this);

        splashHandler = new Handler();
        splashRunnable = new Runnable()
        {
            @Override
            public void run()
            {
                SplashScreenActivity.this.finish();
                Intent mainIntent = new Intent(SplashScreenActivity.this, HomeActivity.class);
                startActivity(mainIntent);
            }
        };

        splashHandler.postDelayed(splashRunnable, SPLASH_DISPLAY_LENGTH);

    }

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_DOWN){
            splashHandler.removeCallbacks(splashRunnable);
            SplashScreenActivity.this.finish();
            Intent mainIntent = new Intent(SplashScreenActivity.this, HomeActivity.class);
            startActivity(mainIntent);
        }
        return true;
    }
}
