你能帮助我吗？我尝试过：

 的ImageButton imgbt =（的ImageButton）findViewById（R.id.imgbutton）;
乌里imgUri = Uri.parse（/数据/数据​​/ MyFolder中/ myimage.png）;
imgbt.setImageUri（imgUri）;
 

但我没有看到任何东西，只是一个空白按钮。

解决方案

 私人位图getImageBitmap（字符串URL）{
        位图BM = NULL;
        尝试 {
            URL aURL =新的网址（URL）;
            URLConnection的康恩= aURL.openConnection（）;
            conn.connect（）;
            InputStream的是= conn.getInputStream（）;
            的BufferedInputStream双=新的BufferedInputStream（是）;
            BM = BitmapFactory.de codeStream（之二）;
            bis.close（）;
            is.close（）;
       }赶上（IOException异常E）{
           Log.e（TAG，错误获取位图，E）;
       }
       返回BM;
    }
 

Can you help me please? I've tried :

ImageButton imgbt=(ImageButton)findViewById(R.id.imgbutton);
Uri imgUri=Uri.parse("/data/data/MYFOLDER/myimage.png");
imgbt.setImageUri(imgUri);

but I didn't see anything, simply a void button.

解决方案

    private Bitmap getImageBitmap(String url) {
        Bitmap bm = null;
        try {
            URL aURL = new URL(url);
            URLConnection conn = aURL.openConnection();
            conn.connect();
            InputStream is = conn.getInputStream();
            BufferedInputStream bis = new BufferedInputStream(is);
            bm = BitmapFactory.decodeStream(bis);
            bis.close();
            is.close();
       } catch (IOException e) {
           Log.e(TAG, "Error getting bitmap", e);
       }
       return bm;
    }
