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,

[html] view plain copy

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);

}

[html] view plain copy

/**

* 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,
