How to get the activity to wait before jumping to the next activity on its own in Android?

Question

I want to create an activity that opens when I start my app, wait some time and jumps to the next activity without the user pressing anything.

Here is my code:

public class MainActivity extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Thread thread = new Thread();
    thread.start();
}

public class waitSeconds extends Thread {

    public void run() {
        Log.i("MyActivity", "MyClass");
        try {
            wait(300);
            Intent intent = new Intent(MainActivity.this, main_window.class);
            startActivity(intent);

        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
}

As it seems that it is never going to the "run" method.

How can I do this?

Answer 1

include this in your Activity:

 public class MainActivity extends Activity{
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    SplashHandler handler=new SplashHandler();
    Message msg = new Message();
    msg.what = 0;
    handler.sendMessageDelayed(msg, 3000);

}

private class SplashHandler extends Handler {

            public void handleMessage(Message msg)
              {
                switch (msg.what)
                {
                default:
                case 0:
                  super.handleMessage(msg);

                  Intent intent = new Intent(MainActivity.this,main_window.class);
                  startActivity(intent);
                  MainActivity.this.finish();
                }
              }
        }
