调用java在图像控件中显示网络图片

首先打开iapp,然后开始操作。

新建webpic.mjava

代码:

import android.graphics.drawable.BitmapDrawable;

import java.net.HttpURLConnection;

import java.net.URL;

import java.io.InputStream;

import android.graphics.Bitmap;

import android.graphics.BitmapFactory;

 

public static BitmapDrawable get(String url){

BitmapDrawable pic = null;

try{

URL u = new URL(url);

HttpURLConnection conn = (HttpURLConnection) u.openConnection();

conn.setRequestMethod(”GET”);

conn.setConnectTimeout(5000);

conn.setReadTimeout(5000);

InputStream is = conn.getInputStream();

Bitmap bmp = BitmapFactory.decodeStream(is);

pic = new BitmapDrawable(bmp);

is.close();

conn.disconnect();

}catch(Exception e){}

return pic;

}

iyu调用

代码:

t(){

s id=图像控件id

s img_url=”网络图片地址,双引号不能少”

call(img,”mjava”,”webpic.get”,img_url)

ufnsui(){

us(id, ”src”, img)

}

}
