带有圆角脑卒中位图图像 [英] Bitmap image with rounded corners with stroke

问题描述

我有锐利边缘的图像。

I have a image with sharp edges.

在tile_mode.xml

the tile_mode.xml

<?xml version="1.0" encoding="utf-8"?>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
    android:src="@drawable/background"
    android:tileMode="repeat">
</bitmap>

在back.xml

the back.xml

<?xml version="1.0" encoding="UTF-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">  
       <item android:drawable="@drawable/tile_mode" />
    <item>
        <shape>
            <solid/>
            <stroke android:width="1dip" android:color="#225786" />
            <corners android:radius="10dip"/>
            <padding android:left="0dip" android:top="0dip" android:right="0dip" android:bottom="0dip" />
        </shape>
    </item> 

layout.xml

layout.xml

<LinearLayout
                android:id="@+id/frame1"
                android:background="@drawable/back"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content">
            </LinearLayout>

我设置的图片作为背景，以这个布局，并绘制它的边界，但问题是图像是方形的有锐边和我在XML正在绘制边框圆角。因此，如何使图像还带有圆角？

I am setting the image as a background to this layout and drawing a border to it but the problem is the image is square with sharp edges and the border which I am drawing in the xml is rounded corners. So how to make the image also with rounded corners?

推荐答案

这是解决方案之一，你必须进行一轮主布局的背景并保持内部你的的ImageView与你的愿望图像：

This is one of solution in which you have to make round to your main layout background and inside keep your imageview with your desire image:

应该如下：

back.xml 的

这会使你的形象圆角的

<?xml version="1.0" encoding="UTF-8"?> 
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle"> 
     <stroke android:width="1dp" android:color="#dd7b7a"/>
     <corners android:bottomRightRadius="10dp" android:bottomLeftRadius="10dp" 
     android:topLeftRadius="10dp" android:topRightRadius="10dp"/> 
     <solid android:color="#dd7b7a"/>
 </shape>

* tile_mode.xml *

*tile_mode.xml*

<?xml version="1.0" encoding="utf-8"?>
<bitmap xmlns:android="http://schemas.android.com/apk/res/android"
android:src="@drawable/background"
android:tileMode="repeat" />

layout.xml 的

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="center"
    >
<LinearLayout 
     android:padding="4dip"
    android:orientation="vertical"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/back"
    android:gravity="center_horizontal"
    >
<LinearLayout  
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
   android:background="@drawable/tile_mode"
    />
</LinearLayout>  
</LinearLayout>

更新

挖地段后，我碰到对的解决方案，它已经张贴在计算器

After digging lots, I came across on of solution which already posted on stackoverflow

更改图像为圆角

<一个href="http://stackoverflow.com/questions/2459916/how-to-make-an-imageview-to-have-rounded-corners">How作出的ImageView有圆角

第一步@

的main.xml 的

 <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center"
        tools:context=".MainActivity" >

        <ImageView
            android:id="@+id/image"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerHorizontal="true"

          />

    </RelativeLayout>

Step2@

请一个函数使用的帆布这使得整到你的位图。

Make one function which make rounded to your bitmap using canvas.

public static Bitmap getRoundedCornerBitmap(Bitmap bitmap, int pixels) {
        Bitmap output = Bitmap.createBitmap(bitmap.getWidth(), bitmap
                .getHeight(), Config.ARGB_8888);
        Canvas canvas = new Canvas(output);

        final int color = 0xff424242;
        final Paint paint = new Paint();
        final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());
        final RectF rectF = new RectF(rect);
        final float roundPx = pixels;

        paint.setAntiAlias(true);
        canvas.drawARGB(0, 0, 0, 0);
        paint.setColor(color);
        canvas.drawRoundRect(rectF, roundPx, roundPx, paint);

        paint.setXfermode(new PorterDuffXfermode(Mode.SRC_IN));
        canvas.drawBitmap(bitmap, rect, rect, paint);

        return output;
    }

step3@

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        ImageView image=(ImageView)findViewById(R.id.image);


        Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.testing);


    image.setImageBitmap(getRoundedCornerBitmap(bitmap, 20));
