android - 单击后退按钮时不会终止启动画面 Activity

Question

这是我的代码。很简单..但是当我点击后退按钮时，第二个 Activity 出现..

 public class MainActivity extends ActionBarActivity {

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

    Thread t = new Thread(){
        public void run(){
            try{
                sleep(3000);

            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }finally{
                Intent i = new Intent(MainActivity.this,SecondActivity.class);
                startActivity(i);
            }
        }
    };
    t.start();
 }

 @Override
 protected void onPause() {
    // TODO Auto-generated method stub
    super.onPause();
    this.finish();
  }

}

我也放入了 list 文件，但我还是遇到了同样的问题..

        android:noHistory="true"

} finally {
   Intent intent = new Intent();
   intent.setClass(SplashActivity.this, MainActivity.class);
   intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
   startActivityForResult(intent, 0);
   finish();
}
