Android用Dialog作遮照层组件-526互联

1Dialog作蒙版，多层遮罩，布局编写，背景点击，背景样式，，2EditText不可点击，隐藏光标，键盘隐藏，多行显示，3RecyclerView设置最大高度，滚动条显示，4.自定义单选框 5. dkVideoPlay 6. pdf

意义：Android里使用Dialog组件作为遮罩层

步骤：

　　1. 继承DialogFragment类

　　2. 重写onCreate()

　　　　设置样式setStyle(DialogFragment.STYLE_NORMAL, R.style.MyDialogFragmentStyle)，其中R.style.MyDialogFragmentStyle要在theme.xml里：　　　　

  @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //设置样式
        setStyle(DialogFragment.STYLE_NORMAL, R.style.MyDialogFragmentStyle);
    }

<style name="MyDialogFragmentStyle" parent="Theme.AppCompat.Light.Dialog">
    <!--  设置设置背景透明颜色      -->
    <item name="android:windowBackground"> #ffffff </item>
    <!--     设置蒙版颜色和不透明的度   -->
    <item name="android:backgroundDimAmount"> 0.2 </item>
</style>

　　3. 重写onCreateView()，编写布局。

@Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.item_dialog3,container,false);
        edtPointName = view.findViewById(R.id.edtPointName);
        edtPointImage = view.findViewById(R.id.edtPointImage);
        edtPointDes = view.findViewById(R.id.edtPointDes);
        edtPointVideo = view.findViewById(R.id.edtPointVideo);
        edtPointVoice = view.findViewById(R.id.edtPointVoice);

        txtCancel = view.findViewById(R.id.txtCancel);
        txtCertain = view.findViewById(R.id.txtCertain);

        cboxDes = view.findViewById(R.id.cboxDes);
        cboxVideo = view.findViewById(R.id.cboxVideo);
        cboxVoice = view.findViewById(R.id.cboxVoice);

        txtCboxDes = view.findViewById(R.id.txtCboxDes);
        txtCboxVideo = view.findViewById(R.id.txtCboxVideo);
        txtCboxVoice = view.findViewById(R.id.txtCboxVoice);

        layoutEdit = view.findViewById(R.id.layoutEdit);
        rvFiles = view.findViewById(R.id.rvFiles);
        rvFilesAdapter = new RvFilesAdapter(getContext(),rvFilesArray);
        rvFilesAdapter.setOnItemClickListener(this);
        rvFiles.setAdapter(rvFilesAdapter);
        rvFiles.setLayoutManager(new LinearLayoutManager(getContext()));

        rvPickImages = view.findViewById(R.id.rvPickImages);
        rvPickImageAdapter = new RvPickFilesAdapter(getContext(),rvPickImageArray);
        rvPickImages.setAdapter(rvPickImageAdapter);
        rvPickImages.setLayoutManager(new LinearLayoutManager(getContext()));

        rvPickDes = view.findViewById(R.id.rvPickDes);
        rvPickDesAdapter = new RvPickFilesAdapter(getContext(),rvPickDesArray);
        rvPickDes.setAdapter(rvPickDesAdapter);
        rvPickDes.setLayoutManager(new LinearLayoutManager(getContext()));

        rvPickVideo = view.findViewById(R.id.rvPickVideo);
        rvPickVideoAdapter = new RvPickFilesAdapter(getContext(),rvPickVideoArray);
        rvPickVideo.setAdapter(rvPickVideoAdapter);
        rvPickVideo.setLayoutManager(new LinearLayoutManager(getContext()));

        rvPickVoice = view.findViewById(R.id.rvPickVoice);
        rvPickVoiceAdapter = new RvPickFilesAdapter(getContext(),rvPickVoiceArray);
        rvPickVoice.setAdapter(rvPickVoiceAdapter);
        rvPickVoice.setLayoutManager(new LinearLayoutManager(getContext()));

        txtCertain.setOnClickListener(this);
        txtCancel.setOnClickListener(this);
        edtPointImage.setOnClickListener(this);
        edtPointDes.setOnClickListener(this);
        edtPointVideo.setOnClickListener(this);
        edtPointVoice.setOnClickListener(this);
        return view;
    }

　　　　4.编写布局文件

　　　　　　外层Layout会被忽视，还需要一个内部layout
