Question

我有一个带有edittext的片段。当我点击edittext时，键盘会显示出来。问题是当我打开抽屉时，抽屉不会隐藏键盘。即使我切换到另一个片段，键盘仍然显示。打开抽屉时，如何隐藏键盘。

我试着把

InputMethodManager imm = 
                        (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.hideSoftInputFromWindow(getWindowToken(), 0);

和

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

它们都不会隐藏键盘。

Answer 1

试试这个......

@Override
protected void onCreate(Bundle savedInstanceState) {
    ......

    //Initialize
    drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);

    //Setting the actionbarToggle to drawer layout
    drawerLayout.setDrawerListener(actionBarDrawerToggle);

    //calling sync state is necessay or else your hamburger icon wont show up
    actionBarDrawerToggle.syncState();

}

DrawerListerner：

 ActionBarDrawerToggle actionBarDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.app_name, R.string.app_name) {

        @Override
        public void onDrawerClosed(View drawerView) {
            // Code here will be triggered once the drawer closes as we dont want anything to happen so we leave this blank
            super.onDrawerClosed(drawerView);
            InputMethodManager inputMethodManager = (InputMethodManager)
                    getSystemService(Context.INPUT_METHOD_SERVICE);
            inputMethodManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
        }

        @Override
        public void onDrawerOpened(View drawerView) {
            // Code here will be triggered once the drawer open as we dont want anything to happen so we leave this blank
            super.onDrawerOpened(drawerView);
            InputMethodManager inputMethodManager = (InputMethodManager)
                    getSystemService(Context.INPUT_METHOD_SERVICE);
            inputMethodManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
        }
    };

快乐的编码......

请在打开/关闭幻灯片抽屉之前使用此行代码

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

已弃用抽屉侦听器，您可以使用 mDrawerLayout.addDrawerListener（）检测导航抽屉状态更改并关闭键盘onDrawerStateChange

mDrawerLayout.addDrawerListener(new DrawerLayout.DrawerListener() {

    @Override
    public void onDrawerSlide(View drawerView, float slideOffset) {
        //Called when a drawer's position changes.

    }

    @Override
    public void onDrawerOpened(View drawerView) {
        //Called when a drawer has settled in a completely open state.
        //The drawer is interactive at this point.
        // If you have 2 drawers (left and right) you can distinguish 
        // them by using id of the drawerView. int id = drawerView.getId(); 
        // id will be your layout's id: for example R.id.left_drawer            
    }

    @Override
    public void onDrawerClosed(View drawerView) {
        // Called when a drawer has settled in a completely closed state.
    }

    @Override
    public void onDrawerStateChanged(int newState) {
        // Called when the drawer motion state changes. The new state will be one of STATE_IDLE, STATE_DRAGGING or STATE_SETTLING.
        InputMethodManager inputMethodManager = (InputMethodManager)
                getSystemService(Context.INPUT_METHOD_SERVICE);
        inputMethodManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);

    }
});

问题是必须从当前“持有”键盘的View中调用getWindowToken()。这很烦人，我同意你的意见，但这就是它的工作方式。

例如，假设EditText mEditText是当前焦点接收键盘击键的对象。那么你的代码就是：

 InputMethodManager imm = 
                    (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(mEditText.getWindowToken(), 0);

希望它有所帮助。

Answer 5

我创建了自己的Helper类来显示或隐藏键盘。

这是...

public static class Helper {

    public static void showKeyboard(Activity activity) {
        InputMethodManager imm = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
        if (imm != null) {
            imm.showSoftInput(activity.getCurrentFocus(), InputMethodManager.SHOW_IMPLICIT);
        }
    }

    public static void hideKeyboard(Activity activity) {
        InputMethodManager imm = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
        if (imm != null && activity.getCurrentFocus() != null) {
            imm.hideSoftInputFromWindow(activity.getCurrentFocus().getWindowToken(), 0);
        }
    }

}

呼叫Helper.showKeyboard(this)以显示键盘。调用Helper.hideKeyboard(this)隐藏键盘。 this指的是活动。

Answer 6

这是到目前为止我提出的最简单的最佳解决方案。您要做的就是创建一个InputMethodManager对象。向DrawerLayout对象添加一个侦听器，最后在以下方法inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(),0);中添加代码行，这很高兴。

InputMethodManager inputMethodManager = (InputMethodManager) this.getSystemService(Activity.INPUT_METHOD_SERVICE);

    drawerLayout.addDrawerListener(new DrawerLayout.DrawerListener() {
        @Override
        public void onDrawerSlide(@NonNull View view, float v) {
            inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(),0);
        }
        @Override
        public void onDrawerOpened(@NonNull View view) {
            inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(),0);
        }

        @Override
        public void onDrawerClosed(@NonNull View view) {
            inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(),0);
        }

        @Override
        public void onDrawerStateChanged(int i) {
        }
    });

**如果您将切换开关与抽屉一起使用，则在onCreate方法中手动添加onDrawerStateChanged **

DrawerLayout抽屉= findViewById（R.id.drawer_layout）; // ActionBarDrawerToggle toggle = new ActionBarDrawerToggle（this，抽屉，appToolBar，R.string.Open_Drawer，R.string.Close_Drawer）;

    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawerLayout, appToolBar, R.string.app_name, R.string.app_name) {

        @Override
        public void onDrawerClosed(View drawerView) {
            // Code here will be triggered once the drawer closes as we dont want anything to happen so we leave this blank
            super.onDrawerClosed(drawerView);
           /* InputMethodManager inputMethodManager = (InputMethodManager)  getSystemService(Activity.INPUT_METHOD_SERVICE);
            inputMethodManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
    */    }

        @Override
        public void onDrawerOpened(View drawerView) {
            // Code here will be triggered once the drawer open as we dont want anything to happen so we leave this blank
            super.onDrawerOpened(drawerView);
          /*  InputMethodManager inputMethodManager = (InputMethodManager)  getSystemService(Activity.INPUT_METHOD_SERVICE);
            inputMethodManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
   */     }

        @Override
        public void onDrawerStateChanged(int newState) {
            // Called when the drawer motion state changes. The new state will be one of STATE_IDLE, STATE_DRAGGING or STATE_SETTLING.
            InputMethodManager inputMethodManager = (InputMethodManager)
                    getSystemService(Context.INPUT_METHOD_SERVICE);
            inputMethodManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);

        }
    };




    drawer.addDrawerListener(toggle);

    toggle.syncState();

导航抽屉在onDrawerOpened时隐藏键盘
