让用户从drawable文件夹中选择图像

Question

我想从我的android studio drawable文件夹中选择image，现在我有两个名为example.jpg和sue.png的图像。我将数组定义为

int image[] = {R.drawable.example, R.drawable.sue};

我应该如何进一步开放他们作为一个画廊，并让用户从中挑选一个？（如下第二幅图所示）

试试这个。在按钮中单击

public void imageChooser() {
    // Gallery Intent
    Intent galleryIntent = new Intent();
    galleryIntent .setType("image/*");
    galleryIntent .setAction(Intent.ACTION_GET_CONTENT);
    startActivityForResult(Intent.createChooser(galleryIntent , "Select Picture"), 200);
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (resultCode == RESULT_OK) {
        if (requestCode == 200) {
            // Get the uri 
            Uri selectedImageUri = data.getData();
            if (null != selectedImageUri) {
                // update your imageview 
                yourimageview.setImageURI(selectedImageUri);
            }
        }
    }
}
