android 解决小米手机上选择照片路径为null情况

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,

if (data == null) {
return;
}
uri = data.getData();
uri = geturi(data);//解决方案
String[] proj = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, proj, null, null, null);
if(cursor!=null){
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
String path = cursor.getString(column_index);// 图片在的路径
Intent intent3 = new Intent(this, SYClipActivity.class);
intent3.putExtra("path", path);
startActivityForResult(intent3, IMAGE_COMPLETE);
}

/**
* 解决小米手机上获取图片路径为null的情况
* @param intent
* @return
*/
public Uri geturi(android.content.Intent intent) {
Uri uri = intent.getData();
String type = intent.getType();
if (uri.getScheme().equals("file") && (type.contains("image/"))) {
String path = uri.getEncodedPath();
if (path != null) {
path = Uri.decode(path);
ContentResolver cr = this.getContentResolver();
StringBuffer buff = new StringBuffer();
buff.append("(").append(Images.ImageColumns.DATA).append("=")
.append("'" + path + "'").append(")");
Cursor cur = cr.query(Images.Media.EXTERNAL_CONTENT_URI,
new String[] { Images.ImageColumns._ID },
buff.toString(), null, null);
int index = 0;
for (cur.moveToFirst(); !cur.isAfterLast(); cur.moveToNext()) {
index = cur.getColumnIndex(Images.ImageColumns._ID);
// set _id value
index = cur.getInt(index);
}
if (index == 0) {
// do nothing
} else {
Uri uri_temp = Uri
.parse("content://media/external/images/media/"
+ index);
if (uri_temp != null) {
uri = uri_temp;
}
}
}
}
return uri;
}

在此记录下,
