Question

以下是代码，如果单击按钮，则应该开始结果活动：

 public class Tab19 extends Activity {

ImageButton button1;
SoundPool mSoundPool;
AssetManager assets;
int catSound;
int countLoadedSound;
Context mContext;
ProgressDialog dialog;
int count = 0;
TextView t;
boolean has_been_clicked = false;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_tab19);


    count = getIntent().getIntExtra("CountNum", 0); 
    mContext = this;        
    mSoundPool = new SoundPool(2, AudioManager.STREAM_MUSIC, 0);
    assets = getAssets();       
    catSound = loadSound("catSound.mp3");

    button1 = (ImageButton)findViewById(R.id.button2);
    button1.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            playSound(catSound);
            Intent firstIntent = new Intent(Tab19.this, Results.class);
            TextView t = (TextView)findViewById(R.id.t);
            t.setText("score: " + ++count +"/18");
            firstIntent.putExtra("CountNum", count);
            has_been_clicked = true;
            startActivity(firstIntent);                 
            finish();
        }
    }); 

    new Thread(
              new Runnable() { 
                public void run() { 
                  while (!has_been_clicked) {

                      try {
                            // Thread will sleep for 10 seconds
                            sleep(10*1000);

                      } catch (Exception e) {

                        }

                  }
                  Intent i=new Intent(getBaseContext(),Results.class);
                    i.putExtra("CountNum", count);
                  startActivity(i);
                  finish();
                  return;

                }

                private void sleep(int i) {
                    // TODO Auto-generated method stub

                }
              }
            ).start();   }  

    @Override
    protected void onDestroy() {

        super.onDestroy(); }

        protected void playSound(int sound) {
            if (sound > 0)
                mSoundPool.play(sound, 1, 1, 1, 0, 1);
        }

        private int loadSound(String fileName) {
            AssetFileDescriptor afd = null;
            try {
                afd = assets.openFd(fileName);
            } catch (IOException e) {
                e.printStackTrace();
                Toast.makeText(this, "Не могу загрузить файл " + fileName,
                        Toast.LENGTH_SHORT).show();
                return -1;
            }

            return mSoundPool.load(afd, 1);

} }

如果没有点击按钮，Thread应该在10秒内启动下一个Activity，但是没有发生，请帮我找错。提前致谢

进入你的线程，将while循环更改为if语句：

 if (!has_been_clicked) {
     try {
          // Thread will sleep for 10 seconds
          sleep(10*1000);
     } catch (Exception e) {
     }
}

我认为您应该将代码更改为

              boolean has_been_clicked = true;
              ...
              while (has_been_clicked) {
                  has_been_clicked = false;
                  try {
                        // Thread will sleep for 10 seconds
                        sleep(10*1000);

                  } catch (Exception e) {

                    }
              }
              Intent i=new Intent(getBaseContext(),Results.class);
                i.putExtra("CountNum", count);
              startActivity(i);
              finish();
              return;

我的代码中的线程不起作用
