try below code:-

getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

or

import android.os.PowerManager;

public class MyActivity extends Activity {

protected PowerManager.WakeLock mWakeLock;

/** Called when the activity is first created. */
@Override
public void onCreate(final Bundle icicle) {
    setContentView(R.layout.main);

    /* This code together with the one in onDestroy() 
     * will make the screen be always on until this Activity gets destroyed. */
    final PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
    this.mWakeLock = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK, "My Tag");
    this.mWakeLock.acquire();
}

@Override
public void onDestroy() {
    this.mWakeLock.release();
    super.onDestroy();
}
}

Do something like below,

protected PowerManager.WakeLock wakelock;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(final Bundle savedInstances) {
        setContentView(R.layout.main);

        final PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
        this.wakelock= pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK, "My Tag");
        this.wakelock.acquire();
    }

    @Override
    public void onDestroy() {
        this.wakelock.release();
        super.onDestroy();
    }

don't forget to add the following permission in manifest file :

<uses-permission android:name="android.permission.WAKE_LOCK" />
