推荐答案

在点击图库按钮，开始startActivityForResult如下：

On click of the gallery button, start startActivityForResult as follows:

startActivityForResult(new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI), GET_FROM_GALLERY);

因此​​，检测GET_FROM_GALLERY（这是一个静态的INT，您所选择的任何请求数量，例如，公共静态最终诠释GET_FROM_GALLERY = 3; ）。里面onActivityResult

Consequently, detect GET_FROM_GALLERY (which is a static int, any request number of your choice e.g., public static final int GET_FROM_GALLERY = 3;) inside onActivityResult.

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);


    //Detects request codes
    if(requestCode==GET_FROM_GALLERY && resultCode == Activity.RESULT_OK) {
        Uri selectedImage = data.getData();
        Bitmap bitmap = null;
        try {
                bitmap = MediaStore.Images.Media.getBitmap(this.getContentResolver(), selectedImage);
        } catch (FileNotFoundException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
        } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
        }
    }
}
