使用 ToggleButton 用来展现两种状态，使用 OnDebouncedClickListener 用来防止多次点击确实起了作用屏蔽了无效点击，但也存在1个问题，快速点击时，ToggleButton 的状态还在切换。如何解决？ #tags: android-view

state_list_toolbar_recording.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_checked="true"
          android:drawable="@drawable/ic_menu_stop_rec"/>
    <item android:drawable="@drawable/ic_menu_start_rec"/>
</selector>

ToggleButton.java

    protected void onCreate(@Nullable Bundle savedInstanceState) {
        mOperation1Btn = (ToggleButton) view.findViewById(R.id.operation1);
        mOperation1Btn.setOnClickListener(new OnDebouncedClickListener() {
            @Override
            public void onDebouncedClick(View v) {
                onToolbarOperation1Clicked(mOperation1Btn.isChecked());
            }
        });
    }
    
    protected abstract void onToolbarOperation1Clicked(boolean isChecked);
