问题

I used selector for checkbox it works, but it causes problems for pre lollipop version

<selector xmlns:android="...">
    <item android:state_checked="true"   
        android:drawable="@drawable/checked_icon" />
    <item android:drawable="@drawable/icon" />
</selector>




<CheckBox
 android:button="@drawable/terms_checkbox"/>

it causes resourcNotFoundexception, How to solve the problem, is there any solution?

回答1:

Try this.

    CheckBox checkBox = (CheckBox) findViewById(R.id.checkBox);
    Drawable d = AppCompatDrawableManager.get().getDrawable(this, R.drawable.terms_checkbox);
    checkBox.setButtonDrawable(d);

回答2:

1) In your build.gradle:

android {
    defaultConfig {
        vectorDrawables.useSupportLibrary = true 
    }
}

2) In your Application class:

static {
    AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
}

3) Use app:buttonCompat insted of android:button for CheckBox or buttonCompat insted of android:button your in style.xml

4) In my case I needed to add

android:focusable="true"
android:clickable="true"

parameters in my CheckBox for onClick reaction.

5) And in my case I needed to use androidx.appcompat.widget.AppCompatCheckBox instead of CheckBox in xml layout.

The article was helpfull.
