Android-如何执行回调函数以从图库中选择路径图像

Question

I need to call a function when the user select an image from gallery and get the path of the selected image. Following my code, activated by onclick:

protected Bitmap bitmap;
public void onclick(View v){
        Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);        
        startActivityForResult(i, STATUS);
}

I need a callback function because I want to store the selected image to the variable bitmap like following:

Bitmap bitmap = BitmapFactory.decodeFile(PATH_SELECTED_IMAGE);

How to do a callback function and get the path of selected image?

您可以通过重写onActivityResult（）方法来实现此目的，在该方法中，您需要检查调用画廊意图时给出的请求代码。
