onClick not triggered on LinearLayout with child

Question

I\'ve got a custom LinearLayout with a smaller TextView child. I\'d like to be able to click the area not covered by the TextView, so I set clickable=true and an onclicklist

Answer 1

I faced the same problem, and all the XML Attributes didn't work. I am not sure if this happens because i programmatically inflate and add the views, but this is how i worked around the problem.

I have a Class which extends LinearLayout, with a TextView and an ImageView. After inflating the layout and getting the views, I assigned the child views a OnClickListener, when pressed, executes the LineaLayout's onClickListner.

public class MyView extends LinearLayout {
private OnClickListener clickListener;
ImageView imageView;
TextView textView;

@Override
public void setOnClickListener(@Nullable OnClickListener l) {
    super.setOnClickListener(l);
    clickListener = l;
}

void afterViews() {
    imageView.setOnTouchListener(new OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            clickListener.onClick(MyView.this);
            return false;
        }
    });
    textView.setOnTouchListener(new OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            clickListener.onClick(MyView.this);
            return false;
        }
    });
}

I also tried overriding OnTouchListener, but then my child views didn't have the ripple effect, which I needed.

Answer 2

for every child

android:duplicateParentState="true"

Answer 3

This isn't your case, but I had similar problem with clickable ViewGroup. After a hour of looking for solution a found out that I set android:inputType to TextView inside my ViewGroup which was blocking onClick() listener (no idea why)

Don't use android:inputType with TextView

Answer 4

The problem may be from the textview that has android:layout_height="fill_parent" in its layout. If that doesn't fix the issue, the problem may be the onClick() event. The linear layout may not actually ever call onClick() since its a layout. Try overriding the onTouch() event listener instead.

Answer 5

I faced the same problem, and all the XML attributes didn't work. I think this happens because I programmatically inflate and add the views. The fix for me was to - also that programatically - set the inflated root view not clickable:

View view = layoutInflater.inflate(R.layout.some_layout, someLinearLayout, false);
view.setClickable(false);

(Yes, I tried to have the some_layout not clickable in XML.)

Answer 6

The android:duplicateParentState="true" made my TextView looks like it's disabled, and cannot receive click event.

All you need is set the TextView clickable="false". So the click event will dispatch to parent layout, and the TextView still can react to touch event (with ripple effect).
