我开发了一个自定义组件，在其中实现了 onClick、onLongClick 和 onTouchListener。一切正常，除了 onLongClick 和 onClick 被调用两次，即使我只做了一次操作。有什么问题请指导解决方案。再次调用方法需要相当长的时间，即约 1 秒。
以下是代码：
自定义小部件：
@BindingMethods({
@BindingMethod(type = RecordingButton.class, attribute = "progress", method = "setProgress"),
})
public class RecordingButton extends RelativeLayout {
boolean isLongPressed;
boolean isPressed;
private Context mContext;
private int progressBackground, progressColor, progressBarWidth;
private int maxProgress, progress;
private LayoutRecordingBtnBinding itemViewBinding;
private OnRecordingButtonListener listener;
private ValueAnimator progressAnimator;
private View.OnTouchListener viewTouchListener = new View.OnTouchListener() {
@Override
public boolean onTouch(View pView, MotionEvent pEvent) {
pView.onTouchEvent(pEvent);
// We're only interested in when the button is released.
switch (pEvent.getAction()) {
case MotionEvent.ACTION_UP:
isPressed = false;
// We're only interested in anything if our speak button is currently pressed.
if (isLongPressed) {
AppLogger.d("usm_recording_button_2", "onTouch ACTION_UP is called to release longPress");
isLongPressed = false;
// Do something when the button is released.\
if (listener != null)
listener.onStopRecording();
} else {
setTintColor(R.color.fayvo_color);
}
break;
case MotionEvent.ACTION_DOWN:
isPressed = true;
setTintColor(R.color.trans_fayvo_color);
break;
}
return false;
}
};
public RecordingButton(Context context) {
super(context);
initializeView(context, null, 0);
