android 解决小米手机上选择照片路径为null情况

Posted 2020-10-23 再见理想

昨天测试帅哥说他手机选择图库崩溃了,这是一个上传头像的功能,相信很多应用都有这个功能,于是我就把手机拿过来打log看了下返回的路径 为null,在网上搜索了下解决方案,现在把解决方案记录下：

这是在onActivityResult方法中执行的,

 

[html] view plain copy

 

1. if (data == null) {  
2.                 return;  
3.             }  
4.             uri = data.getData();  
5.             uri = geturi(data);//解决方案  
6.             String[] proj = { MediaStore.Images.Media.DATA };  
7.             Cursor cursor = managedQuery(uri, proj, null, null, null);  
8.             if(cursor!=null){  
9.                 int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);  
10.                 cursor.moveToFirst();  
11.                 String path = cursor.getString(column_index);// 图片在的路径  
12.                 Intent intent3 = new Intent(this, SYClipActivity.class);  
13.                 intent3.putExtra("path", path);  
14.                 startActivityForResult(intent3, IMAGE_COMPLETE);  
15.             }
