我有一些问题，但我不知道是什么原因导致这个问题。一旦我点击设置为壁纸按钮对话框自动消失，甚至有时设置壁纸需要很长时间。我尝试设置包括其他解决方案，如包括方法progressDialog！=null但没有任何工作。
这是错误

基本活动

public class BasicActivity extends AppCompatActivity {
     protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_basic);
    ...
    Fragment frag = new Sample_Gallery();
        FragmentManager fragmentManager = getSupportFragmentManager();
        fragmentManager.beginTransaction().replace(R.id.basic_fragment,frag).commit();

Sample_Gallery.Java

FragmentTransaction ft = null;
                if (getFragmentManager() != null) {
                    ft = getFragmentManager().beginTransaction();
                    SlideshowDialogFragment newFragment = SlideshowDialogFragment.newInstance();
                    newFragment.setArguments(bundle);
                    newFragment.show(ft, "slideshow");
                }
