android - onClick() 後の ImageView の無効化

Question

アクティビティ内に onClick() メソッドがあり、その onClick() メソッドが ImageView の写真を変更します。ImageView を無効にして onClick() の後に再描画したいのですが、imageView.invalidate() も imageView.postInvalidate() も view.invalidate() も view.postInvalidate() も ImageView をリフレッシュさせていません。代わりに、次にクリックしたときに更新されます。メソッドは次のとおりです。

public void onImageViewProfileClick(View view) {
    Intent photoPickerIntent = new Intent(Intent.ACTION_PICK);
    photoPickerIntent.setType("image/*");
    // Use this to restrict items to those on the SD card:
    photoPickerIntent.putExtra(Intent.EXTRA_LOCAL_ONLY, true);
    startActivityForResult(photoPickerIntent, REQUEST_CODE);
    if (image != null) {
        imageViewProfile.setImageBitmap(image);
        view.postInvalidate();
    }
}

誰かが解決策を知っていますか?

完全な方法は次のとおりです。
