在Android Studio中选择图像后,java应用程序退出(未调用OnActivityResult)
所以我用这个打开我的图片,点击按钮选择
//Open image chooser
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
photoPickerIntent.setType("image/*");
startActivityForResult(photoPickerIntent, SELECT_PHOTO);
并用于ActivityResult
private final static int SELECT_PHOTO = 12345;
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Log.e("CALLED", "OnActivity Result");
if (requestCode == SELECT_PHOTO && resultCode == RESULT_OK) {
// Let's read picked image data - its URI
Uri pickedImage = data.getData();
// Let's read picked image path using content resolver
String[] filePath = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(pickedImage, filePath, null, null, null);
cursor.moveToFirst();
String imagePath = cursor.getString(cursor.getColumnIndex(filePath[0]));
BitmapFactory.Options options = new BitmapFactory.Options();
options.inPreferredConfig = Bitmap.Config.ARGB_8888;
Bitmap bitmap = BitmapFactory.decodeFile(imagePath, options);
Log.e("img", "It worked");
// Do something with the bitmap
// At the end remember to close the cursor or you will end with the RuntimeException!
cursor.close();
}
}
在logcat中,OnactivityResult没有被调用,我不知道为什么。因此,当我点击按钮时,图像选择器弹出,我选择一个图像,然后它退出回到主屏幕。 我是否遗漏了什么,因为我遵循了其他人的代码,但我仍然得到同样的东西
