android 实现图片的边框

 

方案一：继承ImageView，在onDraw  重写画图函数，在图片边延画条灰色的线

方案二：在灰色背景下，内缩2个像索，再内嵌个图片。

 

package com.xmz.activity;import android.content.Context;import android.graphics.Canvas;import android.graphics.Color;import android.graphics.Paint;import android.graphics.Rect;import android.util.AttributeSet;import android.widget.ImageView;public class ImageViewBorder extends ImageView { private String namespace="http://xmz.com"; private int color; public ImageViewBorder(Context context, AttributeSet attrs) { super(context, attrs); color=Color.parseColor(attrs.getAttributeValue(namespace, "BorderColor"));} @Override protected void onDraw(Canvas canvas) { super.onDraw(canvas); //画边框 暂时去除小边框 Rect rec=canvas.getClipBounds(); rec.bottom--; rec.right--; Paint paint=new Paint(); paint.setColor(color); paint.setStyle(Paint.Style.STROKE); canvas.drawRect(rec, paint); }} 

 

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:xmz="http://xmz.com" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="wrap_content" ><TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="方案一：" /> <com.xmz.activity.ImageViewBorder android:layout_width="124px" android:layout_height="180px" android:background="@drawable/movie" xmz:BorderColor="GRAY" /> <TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="方案二：" /> <LinearLayout android:layout_width="124px" android:layout_height="180px" android:background="@drawable/image_bg" android:padding="2px"> <ImageViewandroid:layout_width="wrap_content" android:layout_height="wrap_content"android:background="@drawable/movie" /> </LinearLayout></LinearLayout>
