Activity com.example.BasicActivity 泄露了最初在此处添加的窗口 DecorView@ec0c7fa[BasicActivity]

Question

我有一些问题，但我不知道是什么导致了这个问题。一旦我单击“设置为壁纸”按钮，对话框就会自动消失，即使有时设置壁纸需要很长时间。我尝试设置包含其他解决方案，例如包含 ondrstroy 方法 ProgressDialog!=null 但没有任何效果。

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");
                }

滑动

  set_as_wal.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            if (getActivity() != null) {
                progressDialog = ProgressDialog.show(getActivity(), "Please wait...", "Set as your wallpaper...", false, true);

                Picasso.get().load(setImgLink).into(new Target() {
                    @Override

                        WallpaperManager wallpaperManager = WallpaperManager.getInstance(getActivity());
                        try {
                            wallpaperManager.setBitmap(bitmap);
                            
                            progressDialog.dismiss();
                            ct_popup.setText("Wallpaper was set");
                            final AlertDialog.Builder builder1 = new AlertDialog.Builder(getActivity());
                            builder1.setView(subView);
                            builder1.setPositiveButton("Close", new DialogInterface.OnClickListener() {

                                    dialog.cancel();
                                   
                                    ((ViewGroup) subView.getParent()).removeView(subView);

                        }
                    }

                    public void onBitmapFailed(Exception e, Drawable errorDrawable) {

                    }

    });

Answer 1

我猜问题是因为设置壁纸时 ProgressDialog 消失了。您可以在调用 Dismiss() 之前添加检查

progressDialog

是否仍然显示。 比如：

try {
wallpaperManager.setBitmap(bitmap);
if (progressDialog != null && progressDialog.isShowing()) {
    progressDialog.dismiss();
}
//...

这将确保 ProgressDialog 仅在仍在显示时才被关闭。
