概述我有 ImageView,我想分享它的图像. 以下是我的代码, btshare.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { View content = findViewById(R.id.full_imag @H_403_4@ 我有 ImageVIEw,我想分享它的图像.

以下是我的代码,

btshare.setonClickListener(new OnClickListener() {        @OverrIDe        public voID onClick(VIEw v) {                 VIEw content = findVIEwByID(R.ID.full_image_vIEw);                 content.setDrawingCacheEnabled(true);                     Bitmap bitmap = content.getDrawingCache();                     file root = Environment.getExternalStorageDirectory();                     file cachePath = new file(root.getabsolutePath() + "/DCIM/Camera/image.jpg");                     try                      {                         root.createNewfile();                         fileOutputStream ostream = new fileOutputStream(root);                         bitmap.compress(CompressFormat.JPEG,100,ostream);                         ostream.close();                     }                      catch (Exception e)                      {                         e.printstacktrace();                     }                 Intent shareIntent = new Intent(Intent.ACTION_SEND);                 Uri phototUri = Uri.parse("/DCIM/Camera/image.jpg");                 shareIntent.setData(phototUri);                 shareIntent.setType("image/*");                 shareIntent.putExtra(Intent.EXTRA_STREAM,phototUri);                 startActivity(Intent.createChooser(shareIntent,"Share Via"));             }      });

当我按下按钮我得到这些错误？

我应该怎么做以及我的程序需要什么权限？我已经声明了以下权限,

<uses-permission androID:name="androID.permission.SET_WALLPAPER"/><uses-permission androID:name="androID.permission.WRITE_EXTERNAL_STORAGE"/>

@H_403_4@解决方法 尝试以下代码来分享您的图片：

Intent share = new Intent(Intent.ACTION_SEND);    share.setType("image/*");    share.putExtra(Intent.EXTRA_STREAM,Uri.fromfile(new file(root.getabsolutePath() + "/DCIM/Camera/image.jpg"));    startActivity(Intent.createChooser(share,"Share via"));

将这些权限添加到AndroIDMenifest.xml

<uses-permission androID:name="androID.permission.WRITE_EXTERNAL_STORAGE" /><uses-permission androID:name="androID.permission.INTERNET" /><uses-permission androID:name="androID.permission.READ_EXTERNAL_STORAGE" />
