我尝试为 RadioButtons 设置自定义可绘制对象，但我遇到了一些问题。（这些drawables只是搞砸了，设计师和我试图找出生成和使用从Paint Code导出的图标的最佳方法）。这些是我的可绘制对象：对于选定的状态

public class SelectedRadioButtonDrawable extends Drawable {
private RectF rectF;

public SelectedRadioButtonDrawable(Context context) {
    final int size = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 48, context.getResources().getDisplayMetrics());
    rectF = new RectF(0, 0, size, size);
}

@Override
public void draw(@NonNull Canvas canvas) {
    StyleKitNameJava.drawSave(canvas, rectF, StyleKitNameJava.ResizingBehavior.AspectFill, true, false);
}

@Override
public void setAlpha(@IntRange(from = 0, to = 255) int alpha) {

}

@Override
public void setColorFilter(@Nullable ColorFilter colorFilter) {

}

@Override
public int getOpacity() {
    return PixelFormat.OPAQUE;
}

对于默认状态：

public class RadioButtonDrawable extends Drawable {
    private RectF rectF;

    public RadioButtonDrawable(Context context) {
        final int size = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 48, context.getResources().getDisplayMetrics());
        rectF = new RectF(0, 0, size, size);
    }

    @Override
    public void draw(@NonNull Canvas canvas) {
        StyleKitNameJava.drawSave(canvas, rectF, StyleKitNameJava.ResizingBehavior.Center, false, false);
    }

    @Override
    public void setAlpha(@IntRange(from = 0, to = 255) int alpha) {

    }

    @Override
    public void setColorFilter(@Nullable ColorFilter colorFilter) {

    }

    @Override
    public int getOpacity() {
        return PixelFormat.OPAQUE;
    }
}

这是我的 DrawableStateList

public class RadioButtonStateList {
private StateListDrawable stateListDrawable;

public StateListDrawable getStateListDrawable(Context context) {
    stateListDrawable = new StateListDrawable();
    Drawable radioButtonDrawable = new RadioButtonDrawable(context);
    Drawable selectedRadioButtonDrawable = new SelectedRadioButtonDrawable(context);
    stateListDrawable.addState(new int[]{android.R.attr.state_selected}, selectedRadioButtonDrawable);
    stateListDrawable.addState(StateSet.WILD_CARD, radioButtonDrawable);
    return stateListDrawable;
}
}

我在这里设置了单选按钮

            for (VoteMonsterOption option : options) {
            optionName = option.getOption();
            optionId = option.getId();
            RadioButton radioButton = new RadioButton(getContext());
            radioButton.setPadding(padding, padding, padding, padding);
            radioButton.setButtonDrawable(new RadioButtonStateList().getStateListDrawable(getContext()));
            if (optionName != null) radioButton.setText(optionName);
            if (optionId != null) radioButton.setTag(optionId);
            voteRadioGroup.addView(radioButton);
        }

我的第一个问题，RadioButton 的文本与 Drawable 重叠，我不知道如何解决它。我的第二个问题，状态列表不起作用。如果我单击其中一个按钮，它的可绘制不会更改为选定状态。
