如何在导航切换点击上隐藏Android键盘

Question

当我点击导航按钮时，我想隐藏我的Android应用程序上的键盘。我找了一个解决方案，但没有一个对我有用。

NavigationDrawerActivity

public class NavigationDrawerActivity extends AppCompatActivity

implements NavigationView.OnNavigationItemSelectedListener {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_navigation_drawer);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);

        ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
                this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);

        drawer.setDrawerListener(toggle);
        toggle.syncState();

        NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
        navigationView.setNavigationItemSelectedListener(this);
    }

    @Override
    public void onBackPressed() {
        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        if (drawer.isDrawerOpen(GravityCompat.START)) {
            drawer.closeDrawer(GravityCompat.START);
        } else {
            super.onBackPressed();
        }
    }

    @SuppressWarnings("StatementWithEmptyBody")
    @Override
    public boolean onNavigationItemSelected(MenuItem item) {
        // Handle navigation view item clicks here.
        int id = item.getItemId();

        if (id == R.id.nav_home) {

        } else if (id == R.id.nav_doctor) {

        }  else if (id == R.id.nav_about_us) {

        }else if (id == R.id.nav_feedback) {

        }
            else if (id == R.id.nav_feedback) {

        }

        DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
        drawer.closeDrawer(GravityCompat.START);
        return true;
    }
}

Answer 1

试试这个：

ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(
    this,                 
    mDrawerLayout,        
    R.drawable.ic_drawer,  
    R.string.drawer_open,  
    R.string.drawer_close) {
    @Override
    public void onDrawerStateChanged(int newState) {
             View view = this.getCurrentFocus();
             if (view != null) {  
                 InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
                 imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
             }
    }
});
mDrawerLayout.setDrawerListener(mDrawerToggle);

Answer 2

方法1（如果输入方法已在窗口中显示，隐藏，反过来显示）

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.toggleSoftInput(0, InputMethodManager.HIDE_NOT_ALWAYS);

方法2（视图接受软键盘输入视图，SHOW_FORCED表示强制显示）

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(view,InputMethodManager.SHOW_FORCED);

imm.hideSoftInputFromWindow(view.getWindowToken(), 0);//Forced to hide the keyboard获取输入法打开状态

InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
boolean isOpen=imm.isActive();

Answer 3

当app运行键盘自动打开时，你正在使用编辑文本时出现问题，要停止它你可以添加到你的AndroidManifest.xml：使用编辑文本的Activity名称，就像你在mainActivity中使用edittext一样，然后你写这个： - android：windowSoftInputMode =其他活动的“stateHidden”可以像上面一样调用它。并按后退按钮后添加隐藏键盘代码：

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