有没有办法让 Android 按钮按下 state？

Question

The Android Button has only ACTION_UP , ACTION_DOWN , and ACTION_MOVE states, so I can't hold down the Button for a long time... As a simple example, I want to make a top, bottom, left and right Button and move the square box displayed on the screen ( drawRect drawn on Canvas ). I want to implement a state in which the box continues to rise when the upper button is pressed.

What listener should be attached to the Button ??

Answer 1

you can change the box position when you press down, and when the ACTION_UP event happened, stop box position change

Answer 2
