Question

public class tryAnimActivity extends Activity 
{

  /**
   * The thread to process splash screen events
   */
  private Thread mSplashThread;    

  /** Called when the activity is first created. */
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    // Splash screen view
    setContentView(R.layout.janman);

    final tryAnimActivity sPlashScreen = this;   

    // The thread to wait for splash screen events
    mSplashThread =  new Thread(){
        @Override
        public void run(){
            try {
                synchronized(this){
                    // Wait given period of time or exit on touch
                    wait(5000);
                }
            }
            catch(InterruptedException ex){                    
            }

            finish();

            // Run next activity
            Intent intent = new Intent();
            intent.setClass(sPlashScreen, TabsActivity.class);
            startActivity(intent);
            stop();                    
        }
    };

    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;
  }    
}

这段代码的问题是什么？点击后，它崩溃了。此外，在此活动结束后，下一个活动不会启动。这是用于显示启动画面的活动。

Answer 1

只需删除stop()方法即可使用

我更喜欢使用Runnable元素而不是Thread。我在下面的活动的启动代码运行良好。我希望它对你有所帮助：

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;
    }
}

启动画面不起作用
