.dismiss 后 Android Dialog 不会关闭

如何解决.dismiss 后 Android Dialog 不会关闭

我有一个对话框，它有一个包含多个项目的回收者视图，或者可以说“家庭”，当我点击其中一个时，我想关闭那个对话框并打开另一个带有“产品”的另一个回收者视图已单击的系列，在单击最新产品中的其中一个后，它应该关闭该对话框并打开最后一个对话框，您可以在其中编辑产品。 所以它是这样的：

视图中的按钮 --> 带有回收站的家庭对话框 -- 单击项目上的回收站 --> 带有回收站的该家族的产品 -- 单击项目上的回收站 --> 编辑该项目

当我打开 de Families Dialog，然后关闭它并打开 Products 时，它运行良好。 但是，当我从“产品”对话框中单击产品时，即使“编辑产品”顺利打开，该对话框也不会被关闭，我使用的方法与单击“家庭”中的一个项目时相同，但由于某种原因，它仍然不起作用。

我试过了：

dialogProducts.dismiss();

dialogProducts.cancel();

dialogProducts.hide();

dialogProducts.dismiss();在一个新线程上

dialogProducts.dismiss();在 runOnUiThread

....

这是我的代码草图：

addButton.setonClickListener(v -> {


            final Dialog dialogFamilias = new Dialog(getActivity());
             

            //shows families Dialog,lstItemsFamilia is the items in the recycler view
            mostraFamilias(dialogFamilias,lstItemsFamilia);


            RecyclerView recyclerFamilias = dialogFamilias.findViewById(R.id.recyclerAlert);
            

            recyclerFamilias.addOnItemTouchListener(new MyRecycleViewClickListener(getContext(),new MyRecycleViewClickListener.OnItemClickListener() {
                @Override
                public void onItemClick(View view,int position) {

                    //this one dismiss works
                    dialogFamilias.dismiss();

                    int idFamiliaClicada = lstItemsFamilia.get(position).getId();


                    final Dialog dialogProducts = new Dialog(getActivity());
                    mostraProdutos(dialogProducts,lstItemsProducts);
                    RecyclerView recyclerProducts = dialogProducts .findViewById(R.id.recyclerAlert);



                    recyclerProducts.addOnItemTouchListener(new MyRecycleViewClickListener(getContext(),new MyRecycleViewClickListener.OnItemClickListener() {
                        @Override
                        public void onItemClick(View view,int position) {
                            
                            // this one doesn't dismiss
                            dialogProducts.dismiss();


                            int idProdutoClicado = lstItemsProducts.get(position).getId();
                            final Dialog dialogSingleProduct = new Dialog(getActivity());
                            
                            //shows the final dialog to edit the product 
                            mostraEditarProduto(dialogSingleProduct,idProdutoClicado);

                        }


                    }));


                    }

            }));


        });

MyRecycleViewClickListener 看起来像这样： （它是从 How to click recyclerview items in Activity?)

public class MyRecycleViewClickListener implements RecyclerView.OnItemTouchListener {
    private OnItemClickListener mListener;

    public interface OnItemClickListener {
        public void onItemClick(View view,int position);
    }

    GestureDetector mGestureDetector;

    public MyRecycleViewClickListener(Context context,OnItemClickListener listener) {
        mListener = listener;
        mGestureDetector = new GestureDetector(context,new GestureDetector.SimpleOnGestureListener() {
            @Override
            public boolean onSingleTapUp(MotionEvent e) {
                return true;
            }
        });
    }

    @Override
    public boolean onInterceptTouchEvent(RecyclerView view,MotionEvent e) {
        View childView = view.findChildViewUnder(e.getX(),e.getY());
        if (childView != null && mListener != null && mGestureDetector.onTouchEvent(e)) {
            mListener.onItemClick(childView,view.getChildAdapterPosition(childView));
        }
        return false;
    }

    @Override
    public void onTouchEvent(RecyclerView view,MotionEvent motionEvent) {
    }

    @Override
    public void onRequestdisallowInterceptTouchEvent(boolean disallowIntercept) {

    }
}

显示对话框的方法如下所示：

   public void mostraFamilias (Dialog dialogFamilias,List<Itemmodel> lstItemsFamilia){


        dialogFamilias.requestwindowFeature(Window.FEATURE_NO_TITLE);
        dialogFamilias.setContentView(R.layout.selecionador);
        dialogFamilias.setCanceledOnTouchOutside(true);



        TextView text = (TextView) dialogFamilias.findViewById(R.id.tituloAlert);

        text.setText("Selecionar Família");

        int width = (int)(getResources().getdisplayMetrics().widthPixels*0.90);
        int height = (int)(getResources().getdisplayMetrics().heightPixels*0.90);

        dialogFamilias.getwindow().setLayout(width,height);



        RecyclerView recyclerFamilias = (RecyclerView) dialogFamilias.findViewById(R.id.recyclerAlert);
        RecyclerViewItemsAdapter adapterFamilias = new 
        RecyclerViewItemsAdapter(getContext(),lstItemsFamilia);

        GridLayoutManager manager = new GridLayoutManager(getContext(),3);
        recyclerFamilias.setLayoutManager(manager);

        recyclerFamilias.addItemdecoration(new SpacesItemdecoration(20));
        recyclerFamilias.getRecycledViewPool().setMaxRecycledViews(0,0);
        recyclerFamilias.setAdapter(adapterFamilias);

        dialogFamilias.show();


    }

mostraProdutos 方法类似。

解决方法

将这些线移到外面

final Dialog dialogFamilias = new Dialog(getActivity());
final Dialog dialogProducts = new Dialog(getActivity());
final Dialog dialogSingleProduct = new Dialog(getActivity());
addButton.setOnClickListener(v -> {
    ...
}
