code which i am using
public class CustomViewPager extends ViewPager {
private final long SWITCH_TIME_INTERVAL = 5000;
public CustomViewPager(Context context) {
super(context);
// TODO Auto-generated constructor stub
}
public CustomViewPager(Context context, AttributeSet attributeSet) {
super(context, attributeSet);
postDelayed(mSwither, SWITCH_TIME_INTERVAL);
}
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int height = 0;
for (int i = 0; i < getChildCount(); i++) {
View child = getChildAt(i);
child.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
int h = child.getMeasuredHeight();
if (h > height)
height = h;
}
heightMeasureSpec = MeasureSpec.makeMeasureSpec(height, MeasureSpec.EXACTLY);
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
}
/**

}else
{
count++;
}
//Log.d(this.getClass().getName(), "Curent Page " + count + "");
CustomViewPager.this.setCurrentItem(count, true);
}
CustomViewPager.this.postDelayed(this, SWITCH_TIME_INTERVAL);
}
};

DoubleTap gesture on a Image View

I am a beginner in Android and trying to make a simple tic-tac-toe game . At any time in the game , When a user double tap on a ImageView , I want the images to change (i.e) X will change to O and O will change to X . How do i implement that ?
Here is my code

It's always good to read up on the original Google documents when u first start. http://developer.android.com/reference/android/support/v4/view/GestureDetectorCompat.html gesture detector lets u detect double click.

How to toggle touch event between nested Relative layouts?

I have a Relative layout holds a surface view and another Relative layout (Nested)..
1 ) I want to receive touch events separately for Surface view, if touch events are out of child relative layout. ??
2) if my touch events falls on child relative layout, then the current touch event should not go to surface view.
How to achieve this toggle ???
Thanks in advance..!
Below is my Activity:
public class DragAndDropBasicActivity extends Activity implements OnTouchListener {
private RelativeLayout letterView;
private RelativeLayout mainLayout;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mainLayout = (RelativeLayout) findViewById(R.id.mainLayout);
mainLayout.setOnTouchListener(this);
letterView = (RelativeLayout) findViewById(R.id.mlKnobView);
letterView.setOnTouchListener(this);
}
private boolean dragging = false;
#Override
public boolean onTouch(View v, MotionEvent event) {
boolean eventConsumed = true;
int x = (int)event.getX();
int y = (int)event.getY();
int action = event.getAction();
if (action == MotionEvent.ACTION_DOWN) {
if (v == letterView) {
dragging = true;
eventConsumed = false;
}
} else if (action == MotionEvent.ACTION_UP) {
dragging = false;
eventConsumed = false;
} else if (action == MotionEvent.ACTION_MOVE) {
if (v != letterView) {
if (dragging) {
setAbsoluteLocationCentered(letterView, x, y);
}
}
}
return eventConsumed;
}
private void setAbsoluteLocationCentered(View v, int x, int y) {
setAbsoluteLocation(v, x - v.getWidth() / 2, y - v.getHeight() / 2);
}
private void setAbsoluteLocation(View v, int x, int y) {
RelativeLayout.LayoutParams alp = (RelativeLayout.LayoutParams) v.getLayoutParams();
alp.leftMargin = x;
alp.topMargin = y;
v.setLayoutParams(alp);
}

I Have made it as a widget and Now finally to add this to your List View use
frame = (QuickReturnRelativeLayoutFooter) newProjectsView
.findViewById(R.id.frame);
frame.attach(projectsList);
where projectList is your List View
example
ListView projectList =(ListView)findViewById(R.id.projectList);
and Voila Cheers Completed Smooth as Heaven .......

Android custom TextView not intercepting OnClickListener of parent

I've made a custom TextView that draws lines for every line of text.
This custom TextView is placed in a LinearLayout along with other standard TextViews and ImageViews.
Whenever I click the normal TextViews, ImageViews or outside the custom TextView, the click is intercepted.
But, if I click on the custom TextView, the click is not intercepted.
Please help!!!
Images:
Normal state(minimized)
Maximized state
Click not detected here

try setting onFocusChanged listener to edittext.

Did you mean that, when you click on custom TextView, your convertView's OnClickListener didn't called onClick()?
If yes, you could try disable the custom TextView.
