Question

我在我的应用程序中添加了导航抽屉。到目前为止其他一切工作都很顺利，但我遇到的问题是导航抽屉打开时键盘没有关闭。导航抽屉是主要活动，然后从抽屉打开的每个页面都是一个片段。

我尝试将以下内容添加到片段中的每个EditText区域。但是，这并没有结束任何事情。

InputMethodManager imm1 = (InputMethodManager)getActivity().getSystemService(
            Context.INPUT_METHOD_SERVICE);
        imm1.hideSoftInputFromWindow(input1.getWindowToken(), 0);

我也尝试将该代码放在主要活动中，但也没有成功。关于我可以采用哪些不同的方法来实现这一目标的任何想法？

Answer 1

要在打开或关闭导航栏时隐藏打开的键盘，请覆盖onDrawerSlide中的方法onDrawerListner并添加以下行

InputMethodManager inputMethodManager = (InputMethodManager) actionBarActivity
    .getSystemService(Activity.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(
    actionBarActivity.getCurrentFocus().getWindowToken(),
    0
);

Answer 2

final DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle  actionBarDrawerToggle = new ActionBarDrawerToggle(this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close) {
        @Override
        public void onDrawerClosed(View drawerView) {
            super.onDrawerClosed(drawerView);
       }

        @Override
        public void onDrawerOpened(View drawerView) {
            super.onDrawerOpened(drawerView);
            InputMethodManager inputMethodManager = (InputMethodManager)
                    getSystemService(Context.INPUT_METHOD_SERVICE);
            inputMethodManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
        }

        @Override
        public void onDrawerSlide(View drawerView, float slideOffset) {
            super.onDrawerSlide(drawerView, slideOffset);
            InputMethodManager inputMethodManager = (InputMethodManager)
                    getSystemService(Context.INPUT_METHOD_SERVICE);
            inputMethodManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
        }
    };
    drawer.setDrawerListener(actionBarDrawerToggle);
    actionBarDrawerToggle.syncState();

Answer 3

这对我很有用：

private ActionBarDrawerToggle aDrawerToggle;
private DrawerLayout aDrawerLayout;

我在创建类后在void中使用此代码：

        aDrawerToggle = new ActionBarDrawerToggle(getActivity(), 
        aDrawerLayout, 
        R.drawable.main_icon, 
        R.string.drawer_open, 
        R.string.drawer_close){

        @Override
        public void onDrawerClosed(View drawerView) {
            super.onDrawerClosed(drawerView);
            if (!isAdded()) {
                return;
            }

            InputMethodManager inputMethodManager = (InputMethodManager)getActivity().getSystemService(
                    Context.INPUT_METHOD_SERVICE);


            //inputSearch is my EditText
            inputMethodManager.hideSoftInputFromWindow(inputSearch.getWindowToken(), 0);

            getActivity().supportInvalidateOptionsMenu();
        }
}

Answer 4

在DrawerLayout中添加DrawerListener。然后，您可以使用上面的代码在onDrawerOpened（）方法中关闭键盘

Answer 5

on onCreate：

DrawerLayout drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        drawerLayout.setDrawerListener(new DrawerLayout.DrawerListener() {
            @Override
            public void onDrawerSlide(View drawerView, float slideOffset) {
            }

            @Override
            public void onDrawerOpened(View drawerView) {
            }

            @Override
            public void onDrawerClosed(View drawerView) {
            }

            @Override
            public void onDrawerStateChanged(int newState) {
                InputMethodManager imm = (InputMethodManager)getSystemService(Context.
                        INPUT_METHOD_SERVICE);
                imm.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
            }
        });

Answer 6

尝试此代码，我在我的应用程序中使用它，例如，如果我打开一个包含EditText的对话框我在create.Hope上设置了这个代码，这有助于

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

Answer 7

This does not solve issue.
Correct solution is: Override below method on your main activity:

      public boolean dispatchTouchEvent(MotionEvent ev)
    {

        View view = getCurrentFocus();
        boolean ret = super.dispatchTouchEvent(ev);
if(drawer_open) {

//如果滑块打开则不执行任何操作 } 其他 { if（查看instanceof EditText）{ 查看w = getCurrentFocus（）; int scrcoords [] = new int [2]; w.getLocationOnScreen（scrcoords）; float x = ev.getRawX（）+ w.getLeft（） - scrcoords [0]; float y = ev.getRawY（）+ w.getTop（） - scrcoords [1];

        if (ev.getAction() == MotionEvent.ACTION_UP && (x < w.getLeft() || x >= w.getRight() || y < w.getTop() || y > w.getBottom())) {
            InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(getWindow().getCurrentFocus().getWindowToken(), 0);
        }
    }

        return ret;

    }

自此以来，不赞成使用canvas.setDrawerListener（toggle）。如下所述使用抽屉.addDrawerListener（toggle）

private void initDrawerLayout（）{

    drawer = findViewById(R.id.drawer_layout);
    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle
            (this, drawer, toolbar,
                    R.string.navigation_drawer_open,
                    R.string.navigation_drawer_close)
    {
        @Override
        public void onDrawerClosed(View drawerView) {
            super.onDrawerClosed(drawerView);
            InputMethodManager inputMethodManager = (InputMethodManager)
                    getSystemService(Context.INPUT_METHOD_SERVICE);
            inputMethodManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
        }

        @Override
        public void onDrawerOpened(View drawerView) {
            super.onDrawerOpened(drawerView);
            InputMethodManager inputMethodManager = (InputMethodManager)
                    getSystemService(Context.INPUT_METHOD_SERVICE);
            inputMethodManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
        }
    };
    drawer.addDrawerListener(toggle);
    toggle.syncState();
    drawer.closeDrawer(GravityCompat.START);
}
