Open an activity after a certain amount of time?

Question

I would like to implement a SplashScreen in my app. I found the best and easiest way is to launch an activity that shows a layout with an image view at the launch of the app and then adding android:noHistory="true" attribute to the manifest. Now, how do I set the splashscreen activity to launch the MainActivity class after a certain amount of time? Lets say 2 seconds?

This is my splashscreen activity

public class SplashActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.splashscreen);
}
}

just a warning about using the flag no history - the systen will finish the activity anytime after any other activity is launched. This is quite out of the control of the application code. So do not release anything in the destroy function of the no_history activity . This will lead to unexpected and difficult to debug exceptions — png, Jan 09 '12 at 08:05

use

handler.postDelayed(runnable, delayinmilliseconds(2000 in your case));

final Runnable runnable = new Runnable()
{
    public void run() 
    {
       //start the new activity here.
    }
};

Here is a complete sample.

package com.test.splash;

import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.os.Message;
import android.view.View;
import android.widget.ImageView;

public class splash extends Activity {

    private static final int STOPSPLASH = 0;
    //time in milliseconds
    private static final long SPLASHTIME = 3000;a

    private ImageView splash;

    //handler for splash screen
    private Handler splashHandler = new Handler() {
        /* (non-Javadoc)
         * @see android.os.Handler#handleMessage(android.os.Message)
         */
        @Override
        public void handleMessage(Message msg) {
            switch (msg.what) {
            case STOPSPLASH:
                //remove SplashScreen from view
                splash.setVisibility(View.GONE);
                break;
            }
            super.handleMessage(msg);
        }
    };

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle icicle) {
        super.onCreate(icicle);
        setContentView(R.layout.main);
            splash = (ImageView) findViewById(R.id.splashscreen);
            Message msg = new Message();
            msg.what = STOPSPLASH;
            splashHandler.sendMessageDelayed(msg, SPLASHTIME);
    }
}

public class TrackMyMoneyActivity extends Activity {
//member fields
private ProgressBar pbar = null;
private TextView counter_txt = null;
Thread splash_thread = null;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    pbar = (ProgressBar) findViewById(R.id.splashpbar);

    //define thread

        @Override

            // TODO Auto-generated method stub
            int i = 0;
              for( i=0;i<100;i++){

                  pbar.setProgress(i);

                 // counter_txt.setText(i+" %");
                  try {
                    splash_thread.sleep(100);
                } catch (InterruptedException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }
              }
              if(i==100){
                  Intent intent = new Intent(getBaseContext(), LoginApp.class);
                  startActivity(intent);
              }
        }
    });
    splash_thread.start();

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


}

}

I hope it will be solved your solution.

You can also use java.util.Timer in this way:

new Timer().schedule(new TimerTask(){
    public void run() { 
        startActivity(new Intent(SplashActivity.this, MainActivity.class));
    }
}, 2000 /*amount of time in milliseconds before execution*/ );
