关于#android#的问题：apk软件只有实时拍摄图片上传如何改成相册上传图片

public class MainActivity extends AppCompatActivity {

  private static final int PICK_IMAGE_REQUEST = 1;
  private Button selectImageButton;

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    selectImageButton = findViewById(R.id.select_image_button);
    selectImageButton.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
        openGallery();
      }
    });
  }

  private void openGallery() {
    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) {
      Uri selectedImageUri = data.getData();
      // 从选中的图片路径中获取图片并上传
      // ...
    }
  }
}
