调用系统内置的gallery查看图片

Intent intent = new Intent(Intent.ACTION_GET_CONTENT); 
// 告诉打开的内容

intent.setType("file:///sdcard/image/*");  
startActivityForResult(intent, 1); 

 

protected final void onActivityResult(final int requestCode, final int 
                     resultCode, final Intent i) { 
    super.onActivityResult(requestCode, resultCode, i); 
 
  // this matches the request code in the above call 
  if (requestCode == 1) { 
      Uri _uri = i.getData(); 
 
    // this will be null if no image was selected... 
    if (_uri != null) { 
      // now we get the path to the image file 
     cursor = getContentResolver().query(_uri, null, 
                                      null, null, null); 
     cursor.moveToFirst(); 
     String imageFilePath = cursor.getString(0); 
     cursor.close(); 
     } 
   }
