android - 导航 View 在 Android 中始终可见

Question

我想通过单击底部应用栏打开导航 View 。但导航 View 始终可见。

我的布局 xml:

我的java代码:

package com.stawiz;

    Button btnLogOut,btnEditProfile;

    NavigationView navigationView;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main_menu);

        floatingActionButton = findViewById(R.id.bottom_float_button);

        bottomAppBar = findViewById(R.id.bottombar);

        coordinatorLayout=findViewById(R.id.coordinatorlayout);

        drawerLayout=findViewById(R.id.drawer_layout);

        navigationView  = findViewById(R.id.nav_view);


        setSupportActionBar(bottomAppBar);

       bottomAppBar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() { // It working when profile button pressed.
            @Override
            public boolean onMenuItemClick(MenuItem item) {

                Log.e("asdas","--asdasd");



                if(drawerLayout.isDrawerVisible(Gravity.RIGHT)){
                    Log.e("right","right");
                }
                if(drawerLayout.isDrawerVisible(Gravity.LEFT)){
                    Log.e("LEFT","LEFT");
                }
                if(drawerLayout.isDrawerVisible(GravityCompat.START)){
                    Log.e("START","START");
                }
                if(drawerLayout.isDrawerVisible(GravityCompat.END)){
                    Log.e("END","END");
                }


                return true;
            }
        });

     bottomAppBar.setNavigationOnClickListener(new View.OnClickListener() {//It working when menu button pressed.
         @Override
         public void onClick(View v) {

             BottomNavigationDrawer bottomNavigationDrawer = new BottomNavigationDrawer();

             bottomNavigationDrawer.show(getSupportFragmentManager(),bottomNavigationDrawer.getTag());
         }
     });



    }


    @Override
    public boolean onCreateOptionsMenu(Menu menu) {

        getMenuInflater().inflate(R.menu.bottom_app_bar_menu, menu);
        return super.onCreateOptionsMenu(menu);
    }



    @Override
    public boolean onOptionsItemSelected(MenuItem item) {

      /*  switch (item.getItemId()){

            case

        }*/


        return super.onOptionsItemSelected(item);
    }

    @Override
    public void onBackPressed() {

        if (getSupportFragmentManager().getBackStackEntryCount() == 1) {
            finish();
        } else {
            super.onBackPressed();
        }


    }


}

我想用 bottomAppBar.setOnMenuItemClickListener 显示导航 View 。应用程序在那里，但导航 View 始终显示。我只想用这个点击监听器显示导航 View 。我怎样才能做到这一点 ？提前致谢。

当您开始 Activity 时，您正在打开它。请删除 onCreate 方法中的行

drawerLayout.openDrawer(GravityCompat.START);

和改变

android:layout_gravity="end"

到

android:layout_gravity="start"
