我一直试图获取在KitKat上选择的相册中的图片的绝对路径,但似乎并没有成功。无论我做什么,我的变量IMAGE_FILEPATH
始终为""。这是我的onActivityResult()
代码:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode != Activity.RESULT_OK) return;
if (null == data) return;
Uri originalUri = null;
if (requestCode == 1) {
//JB!!!
Uri uri = data.getData();
if (uri != null) {
try {
// User had pick an image.
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver()
.query(uri,
filePathColumn, null, null, null);
cursor.moveToFirst();
IMAGE_FILEPATH = cursor.getString(0);
cursor.close();
} catch (Exception e) {
Crouton.makeText(this, "Failed to get image", Style.ALERT).show();
}
}
} else if (requestCode == 2) {
//KK!!!
Uri uri = data.getData();
if (uri != null) {
try {
if( uri == null ) {
IMAGE_FILEPATH = uri.getPath();
} else {
String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);
if( cursor != null ){
int column_index = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
IMAGE_FILEPATH = cursor.getString(column_index);
} else {
IMAGE_FILEPATH = uri.getPath();
}
}
} catch (Exception e) {
Crouton.makeText(this, "Failed to get image", Style.ALERT).show();
}
}
}
Resource.toast(IMAGE_FILEPATH);
super.onActivityResult(requestCode, resultCode, data);
}
出了什么问题?我试过多种解决方案,但似乎都没有起作用。
