    <p>First of all I want to Thank SO for being here for the don`t Know hows. Second, I am relative new to android programing and doing this for about 2 weeks now.</p> <p>ok My Question:</p> <p>I`m Writing an app where you have to ttake a picture when you tap on the screen. I managed to do that, but in a later stage of the app you can scroll through more then 1 canvas in the live camera view. So the picture must not be taking when you tap ones on the screen, but when you touch and hold the screen after an X amount of seconds it must take the pucture.</p> <p>so that if you are scrolling through the canvases you dont take the picture on the moment you hit the screen.</p> <p>if tried to register the current time on the <code>ACTION_DOWN</code> event and compare it with the current time + 5000 (miliseconds) are there any sugestions on how to achieve this ?</p> <p>Kind Regards</p> <p><code> public boolean onTouchEvent(MotionEvent event) { if(event.getAction() == MotionEvent.ACTION_DOWN) { long activateTime = System.currentTimeMillis();</p> <pre><code>if(event.getAction() == MotionEvent.ACTION_DOWN &amp;&amp; activateTime + 5000 == System.currentTimeMillis()) { takePicture(); } } return false; }; </code></pre> <p></code></p> <p>EDIT! this source code was the key for me.</p> <p><code></p> <pre>public class GestureDemo extends Activity implements OnGestureListener { private GestureDetector gestureDetector; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); gestureDetector = new GestureDetector(this); } @Override public boolean onTouchEvent(MotionEvent event) { return gestureDetector.onTouchEvent(event); } @Override public boolean onDown(MotionEvent e) { Toast.makeText(this,"oNDown called",Toast.LENGTH_SHORT).show(); return false; } @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { Toast.makeText(this,"oNFling called",Toast.LENGTH_SHORT).show(); return false; } @Override public void onLongPress(MotionEvent e) { Toast.makeText(this,"OnLongPress called",Toast.LENGTH_SHORT).show(); } @Override public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) { Toast.makeText(this,"onScroll called",Toast.LENGTH_SHORT).show(); return false; } @Override public void onShowPress(MotionEvent e) { Toast.makeText(this,"onShowPress called",Toast.LENGTH_SHORT).show(); } @Override public boolean onSingleTapUp(MotionEvent e) { Toast.makeText(this,"oNsingleTap called",Toast.LENGTH_SHORT).show(); return false; } &lt;/code&gt; </code></pre> <p>heres the link where I found the <a href="http://www.androidpeople.com/android-gesture-handling" rel="nofollow">code</a>!</p> <p>Thank you will for pointing me in the right deriction.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
