Android Button Touch Strategy

To handle Android touch events for nested buttons, configure the outer container either as a touch proxy for accessibility or as a non-interactive layout placeholder to ensure interactions hit the correct element.

To make an Android container act as a larger touch target, use the Touch Proxy Strategy to route interactions from the surrounding transparent layout area directly to the inner button element.

To prevent accidental touch activations on transparent areas, use the Layout Placeholder Strategy by setting the outer container to clickable="false" and only the inner element to clickable="true".

For a circular Android button inside a square FrameLayout, either make the entire square frame clickable for a larger touch target or restrict hits to the circle by setting the outer frame to clickable="false".

Use a touch proxy strategy when you need a larger hit target for accessibility, and use a layout placeholder when you must prevent mis-taps in transparent container areas.

An outer FrameLayout intercepts touch events because its default configuration may act as a touch proxy, directing container taps to the inner button instead of ignoring transparent area interactions.
