android - how to catch touch event like game: World Search - matrix

Question

I have a game like WorldSearch on Store, I tried using this solution:
I created matrix by array of TextView and added TouchEvent on each TextView. Then I caught event by MOTION.UP, MOTION.DOWN. When I touched on a TextView and dragged it, although it went thought other TextViews but I just could get event of first TextView.
Here is code:
private void createMetrix(){
// amound of item in a row and column
int itemNum = 10;
// calculate size of item
ScreenDimension screenDimension = Utilities.getFinalScreenDimension(this);
int itemSize = screenDimension.screenWidth / 10;
// mContentLinear has VERTICAL orientation
// then adding children linear layouts, these layout has HORIZONTAL orientation
for(int i = 0; i < itemNum; i++) {
LinearLayout theItemLayout = createHorizontalLayout(itemNum, itemSize, i);
mContentLinear.addView(theItemLayout);
}
}
private LinearLayout createHorizontalLayout(int itemNum, int itemSize, int row) {
LinearLayout theLinear = new LinearLayout(this);
theLinear.setOrientation(LinearLayout.HORIZONTAL);
theLinear.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, itemSize));
for(int i = 0; i < itemNum; i++){
// add item metrix into linear layout having HORIZONTAL orientation
TextView itemTxt = createItemMatrix(itemSize, row, i);
theLinear.addView(itemTxt);
}
return theLinear;
}
private TextView createItemMatrix(int itemSize, int row, int column) {
TextView theItemTxt = new TextView(this);
theItemTxt.setWidth(itemSize);
theItemTxt.setHeight(itemSize);
theItemTxt.setTextSize(13);
theItemTxt.setGravity(Gravity.CENTER);
theItemTxt.setText("A" + row + "" + column);
String tag = row + "|" + column;
theItemTxt.setTag(tag);
theItemTxt.setOnTouchListener(mOnTouchListener);
return theItemTxt;
}
// Listener
private View.OnTouchListener mOnTouchListener = new View.OnTouchListener() {
private Rect rect;
#Override
public boolean onTouch(View v, MotionEvent event) {
if (v == null) return true;
TextView itemTxt = (TextView)v;
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
rect = new Rect(v.getLeft(), v.getTop(), v.getRight(), v.getBottom());
Log.d("TEXT", "MOVE DOWN: " + itemTxt.getText().toString());
return true;
case MotionEvent.ACTION_UP:
if (rect != null
&& !rect.contains(v.getLeft() + (int) event.getX(),
v.getTop() + (int) event.getY())) {
// The motion event was outside of the view, handle this as a non-click event
return true;
}
// The view was clicked.
Log.d("TEXT", "MOVE ON: " + itemTxt.getText().toString());
// TODO: do stuff
return true;
case MotionEvent.ACTION_MOVE:
Log.d("TEXT", "MOVE OUT: " + itemTxt.getText().toString());
return true;
default:
return true;
}
}
};
Does someone have any ideas on this case?
Thanks,
