Question

我有一个地图活动。它有一个导航抽屉。但是，当我单击任何导航项时，我无法进行其他活动。我在这里附加我的代码。没有错误。当我单击导航抽屉中的任何一项时，它不会移动到其他活动。

     nv = (NavigationView) findViewById(R.id.nv);
            nv.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
                @Override
                public boolean onNavigationItemSelected(@NonNull MenuItem item) {
                    int id = item.getItemId();
                    switch (id) {
                        case R.id.profile:

                            Intent i = new Intent(HomeActivity.this, ProfileActivity.class);
                            startActivity(i);
                            break;
                        case R.id.dona:
                            Intent j = new Intent(HomeActivity.this, DonateActivity.class);
                            startActivity(j);

Answer 1

您需要return true末尾的onNavigationItemSelected

  nv.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
                @Override
                public boolean onNavigationItemSelected(@NonNull MenuItem item) {
                    int id = item.getItemId();
                    switch (id) {
                        case R.id.profile:

                            Intent i = new Intent(HomeActivity.this, ProfileActivity.class);
                            startActivity(i);
                            break;

                        /*--your code--*/


                        case R.id.hist:
                            Intent m = new Intent(HomeActivity.this, HistoryActivity.class);
                            startActivity(m);
                            break;

                        case R.id.hel:
                            Intent n = new Intent(HomeActivity.this, HelpActivity.class);
                            startActivity(n);
                            break;



                    }

                yourDrawer.closeDrawer(GravityCompat.START);

                    return true;       //you need to return true here, not false

                }
            });

Answer 2

尝试

我正在使用像这样的直接选中项目的点击方法

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

if (id == R.id.nav_buildings) {
    startActivity(new Intent(SuperAdminHomeActivity.this,BuildingsActivity.class));

} else if (id == R.id.nav_companies) {
    startActivity(new Intent(SuperAdminHomeActivity.this,CompaniesActivity.class));

} else if (id == R.id.nav_reports) {
    startActivity(new Intent(SuperAdminHomeActivity.this,ReportsActivity.class));

} else if (id == R.id.nav_invoice) {
    startActivity(new Intent(SuperAdminHomeActivity.this,InvoiceActivity.class));

} else if (id == R.id.nav_notifications) {
    startActivity(new Intent(SuperAdminHomeActivity.this,NotificationsActivity.class));

} else if (id == R.id.nav_ticket) {
    startActivity(new Intent(SuperAdminHomeActivity.this,TicketActivity.class));

}
else if (id == R.id.nav_my_ticket) {
    startActivity(new Intent(SuperAdminHomeActivity.this,TicketsAddActivity.class));
}

else if(id==R.id.nav_logout){
    alertDialogue("Do you want to logout?");
}

drawer.closeDrawer(GravityCompat.START);
return true;
 }

我没有使用抽屉式点击侦听器。
这是我的抽屉布局

工作正常，请尝试

Answer 3

仔细检查了您的完整代码后，我意识到没有调用.setNavigationItemSelectedListener。即使抽屉正在显示，它也位于活动的后面。因此，您实际上并没有单击它。

所以简单的解决方法是：

nv.bringToFront();

在初始化nv之后将其放入

Answer 4

使您的导航视图成为全局变量

想要从导航抽屉移至另一个活动
