Android中的TimerTask [英] TimerTask in Android

问题描述

大家好
我想在我的android设备上的imageviewer上显示欢迎图片，三秒钟后我想更改活动并将用户发送到程序的其他部分，但是TimerTask似乎不起作用！有人可以帮我吗?

Hi guys
i want to show a welcome picture on imageviewer in my android device and after 3seconds i want to change the activity and send user to some other part of program but my TimerTask seems not working! can any one help me?

public class TicketFinalActivity extends Activity {
    
	ImageView iv;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Timer t = new Timer();
        TimerTask welcome = new TimerTask(){
			
			@Override
			public void run() {
				// TODO Auto-generated method stub
				Intent intent = new   Intent(TicketFinalActivity.this,Caution.class);
				startActivity(intent);
			}
		};
		t.schedule(welcome, 300, 30000);
        iv = (ImageView)findViewById(R.id.GreetView);
        
    }
}

推荐答案

尝试一下:

Try this:

public class TicketFinalActivity extends Activity {

    private final int DELAY_TIME = 1000;

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

        new Timer().schedule(new TimerTask() {
            @Override
            public void run() {
                try {
                    Intent i= new Intent(TicketFinalActivity.this, Caution.class);
                    startActivity(i);
                }
                catch (Exception e) {
                    Log.i("TAG", "Error: " + e.getMessage());
                    finish();
                }
            }
        }, DELAY_TIME);
    }
