專案中用到的一個小控制元件，自帶的控制元件滿足不了需求，只能自定義了。
直接看圖片：

<com.yjy.yijinyi.view.DrawableCenterRadioButton
                android:layout_marginTop="20dp"
                android:id="@+id/dd"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:checked="true"
 

                android:text="RadioButton"
                android:textColor="@color/text_color"
                android:button="@null"
                android:drawableLeft="@drawable/selector_high_evaluation_radiobutton"
                />
            <RadioButton
                android:layout_width="match_parent"
 

                android:layout_height="wrap_content"
                android:text="RadioButton"
                android:textColor="@color/text_color"
                android:gravity="center"
                android:button="@null"
                android:checked="true"
                android:drawableLeft="@drawable
 
/selector_high_evaluation_radiobutton"
                />
        </LinearLayout>

然後就是java程式碼：

package com.yjy.yijinyi.view;

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.widget.RadioButton;

/**

 */
public class DrawableCenterRadioButton extends RadioButton {
    public DrawableCenterRadioButton(Context context) {
        super(context);
    }

    public DrawableCenterRadioButton(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public DrawableCenterRadioButton(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    protected void onDraw(Canvas canvas) {
        Drawable[] drawables = getCompoundDrawables();
        if (drawables != null) {
            Drawable drawableLeft = drawables[0];
            if (drawableLeft != null) {
                float textWidth = getPaint().measureText(getText().toString());
                int drawablePadding = getCompoundDrawablePadding();
                int drawableWidth = 0;
                drawableWidth = drawableLeft.getIntrinsicWidth();
                float bodyWidth = textWidth + drawableWidth + drawablePadding;
                canvas.translate((getWidth() - bodyWidth) / 2, 0);
            }
        }
        super.onDraw(canvas);
    }

}

直接貼上複製就可以使用了，別忘了更換包名。
