如何製作圓形方形組圖標而不是圓形圖標

Question

你好我有一個啓動器，我一直在努力，我想使文件夾圖標像這樣一個圓角正方形：。

現在它是一個圓形的形狀是通過Java代碼再沒使用XML

下面的代碼：

package com.appname.viewutil; 

import android.graphics.Bitmap; 
import android.graphics.Canvas; 
import android.graphics.Color; 
import android.graphics.ColorFilter; 
import android.graphics.Paint; 
import android.graphics.Path; 
import android.graphics.PixelFormat; 
import android.graphics.RectF; 
import android.graphics.Region; 
import android.graphics.drawable.Drawable; 

import com.launchername.activity.Home; 
import com.launchername.util.Tool; 

public class GroupIconDrawable extends Drawable{ 

    private int outlinepad; 
    Bitmap[] icons; 
    public float iconSize; 
    Paint paint; 
    Paint paint2; 
    Paint paint4; 
    private int iconSizeDiv2; 
    private float padding; 

    private float scaleFactor = 1; 

    private boolean needAnimate, needAnimateScale; 

    private float sx = 1; 
    private float sy = 1 ; 

    public GroupIconDrawable(Bitmap[] icons,float size){ 
     init(icons,size); 
    } 

    private void init(Bitmap[] icons,float size){ 
     this.icons = icons; 
     this.iconSize = size; 
     iconSizeDiv2 = Math.round(iconSize/2f); 
     padding = iconSize /25f; 

     this.paint = new Paint(); 
     paint.setColor(Color.WHITE); 
     paint.setAlpha(150); 
     paint.setAntiAlias(true); 

     this.paint4 = new Paint(); 
     paint4.setColor(Color.WHITE); 
     paint4.setAntiAlias(true); 
     paint4.setFlags(Paint.ANTI_ALIAS_FLAG); 
     paint4.setStyle(Paint.Style.STROKE); 
     outlinepad = Tool.dp2px(2, Home.launcher); 
     paint4.setStrokeWidth(outlinepad); 

     this.paint2 = new Paint(); 
     paint2.setAntiAlias(true); 
     paint2.setFilterBitmap(true); 
    } 

    public void popUp(){ 
     sy = 1; 
     sx = 1; 
     needAnimate = true; 
     needAnimateScale = true; 
     invalidateSelf(); 
    } 

    public void popBack(){ 
     needAnimate = false; 
     needAnimateScale = false; 
     invalidateSelf(); 
    } 

    @Override 
    public void draw(Canvas canvas) { 
     canvas.save(); 

     if (needAnimateScale){ 
      scaleFactor = Tool.clampFloat(scaleFactor-0.09f,0.5f,1f); 
     }else { 
      scaleFactor = Tool.clampFloat(scaleFactor+0.09f,0.5f,1f); 
     } 

     canvas.scale(scaleFactor,scaleFactor,iconSize/2,iconSize/2); 

     Path clipp = new Path(); 

     clipp.addCircle(iconSize/2,iconSize/2,iconSize/2-outlinepad, Path.Direction.CW); 
     canvas.clipPath(clipp, Region.Op.REPLACE); 

     canvas.drawCircle(iconSize/2, iconSize/2, iconSize/2-outlinepad,paint); 

     canvas.drawBitmap(icons[0],null,new RectF(padding,padding, iconSizeDiv2-padding, iconSizeDiv2-padding),paint2); 
     canvas.drawBitmap(icons[1],null,new RectF(iconSizeDiv2+padding,padding,iconSize-padding, iconSizeDiv2-padding),paint2); 
     canvas.drawBitmap(icons[2],null,new RectF(padding, iconSizeDiv2+padding, iconSizeDiv2-padding,iconSize-padding),paint2); 
     canvas.drawBitmap(icons[3],null,new RectF(iconSizeDiv2+padding, iconSizeDiv2+padding,iconSize-padding,iconSize-padding),paint2); 

     canvas.clipRect(0,0,iconSize,iconSize, Region.Op.REPLACE); 

     canvas.drawCircle(iconSize/2, iconSize/2, iconSize/2-outlinepad,paint4); 
     canvas.restore(); 

     if (needAnimate){ 
      paint2.setAlpha(Tool.clampInt(paint2.getAlpha()-25,0,255)); 
      invalidateSelf(); 
     }else if (paint2.getAlpha() != 255){ 
      paint2.setAlpha(Tool.clampInt(paint2.getAlpha()+25,0,255)); 
      invalidateSelf(); 
     } 
    } 

    @Override 
    public void setAlpha(int i) {} 

    @Override 
    public void setColorFilter(ColorFilter colorFilter) {} 

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

如何使圓角正方形像圖片什麼想法？

任何幫助都會很棒！

在此先感謝:)

與適當的ROUNDRECT職能 - addRoundRect和drawRoundRect替換爲addCircle和畫圓的電話。
