[英]Getting both Photos and Videos from the new Google Photos app on Android
[英]Not getting the image from android photos app
但是這些仍然不能解決我的問題,所以我要發布一個新問題。
這是我的代碼,用於獲取在“ 照片”應用中選擇的圖像的路徑。 但是我沒有得到cursor.getColumnIndexOrThrow(column); 值為0 ,cursor.getString(column_index)值為null 。
Cursor cursor = null;
final String column = "_data";
final String[] projection = {
column
};
try {
cursor = context.getContentResolver().query(uri, projection, selection, selectionArgs,
null);
if (cursor != null && cursor.moveToFirst()) {
final int column_index = cursor.getColumnIndexOrThrow(column);
return cursor.getString(column_index);
}
} finally {
if (cursor != null)
cursor.close();
}
誰能幫我解決這個問題。 如果我的問題太籠統,請告訴我。 我會更新我的問題。
更新:開始意圖:
Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
intent.setType("image/*");
startActivityForResult(Intent.createChooser(intent, getString(R.string.selectPhoto)), RESULT_LOAD_IMAGE);
在onActivityResult中:
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
String[] projection = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(contentURI, projection, null, null, null);
if (cursor == null) {
return contentURI.getPath();
} else {
cursor.moveToFirst();
int idx = cursor.getColumnIndex(projection[0]);
return cursor.getString(idx);
}
}
問候
用戶下面的代碼
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == RESULT_OK) {
switch (requestCode) {
case Common.Action_Gallery:
if (data != null) {
Uri selectedImage = data.getData();
String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = getContentResolver().query(selectedImage, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
}
break;
}
}
}
