如何在android studio中位图我的画廊图像

Question

大家好，我正在尝试对我的图像进行位图处理，但是每次我从我的图库中选择任何图像时，它都会给我一个空位图。 请帮忙

public void start(View view) {
    Intent intent = new Intent(Intent.ACTION_PICK);
    intent.setType("image/*");
    startActivityForResult(intent, Gallery_Intent); 
}

protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    uri = data.getData();

    imageView.setImageURI(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);
    if (bitmap == null) 
        Toast.makeText(MainActivity.this, "failed1", Toast.LENGTH_SHORT).show();
}

您可以使用 Picasso 或 Glide 更轻松地获得图像位图，示例是使用 Picasso

Bitmap bitmap = Picasso.get().load(uri).get();
