安卓无法将图片从图库设置为ImageViews

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

// 打开图库
Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(intent, PICK_IMAGE_REQUEST);

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {
        Uri imageUri = data.getData();
        imageView.setImageURI(imageUri);
    }
}
