来自file：//系统或文件的WebView图像源：//存储

我想从图库中显示图像WebView但有些东西不起作用。我的webview不想显示源代码如下：file：//storage/sdcard0/Download/obrazek.jpg或file：//system/media/Andy29WP.png。来自file：//系统或文件的WebView图像源：//存储

我的JavaScript桥：

private class MyJavaScriptInterface { 
     @SuppressWarnings("unused") 
     Context mContext; 
     @SuppressWarnings("unused") 
     private static final int SELECT_PICTURE = 1; 
      MyJavaScriptInterface(Context c) { 
       mContext = c; 
      } 
      @JavascriptInterface 
      public void imageChooser(final String id){ 
       Intent intent = new Intent(); 
       intent.setType("image/*"); 
       intent.setAction(Intent.ACTION_GET_CONTENT); 
       startActivityForResult(Intent.createChooser(intent, "Select Picture"),1); 
       String imagePath = ""; 
       String[] imgData = { MediaStore.Images.Media.DATA }; 

       Cursor imgCursor = getContentResolver().query(m_image_uri, imgData, null, null, null); 
       if(imgCursor!=null) { 
        int index = imgCursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA); 
        imgCursor.moveToFirst(); 
        imagePath = imgCursor.getString(index); 
       } 
       else 
        imagePath = m_image_uri.getPath(); 

       m_image_path = imagePath; 
       String test_image_path = "file:/" + m_image_path; 
       Log.i("url obrazka", "url obrazka" + test_image_path); 
       m_web_view.loadUrl("javascript:changeImage(\""+ id + "\",\"" + test_image_path +"\")"); 
      } 
     }

我onActivityResult：

@Override 
    public void onActivityResult(int requestCode, int resultCode, Intent data) { 
      if (resultCode == RESULT_OK) { 
        if (requestCode == 1) { 
          // currImageURI is the global variable I'm using to hold the content:// URI of the image 
          m_image_uri = data.getData(); 
        } 
      } 
    }

应用： Image not displaying in browser

使用file：///存储......不是文件：//存储.... – greenapps 2014-09-24 19:08:42

@greenapps感谢 – Volz 2014-09-24 19:18:52

图片路径应该有三个斜杠而不是两个。

老：

file://storage/sdcard0/Download/obrazek.jpg

新：

file:///storage/sdcard0/Download/obrazek.jpg
