从 NavigationView 启动新活动

Question

I have tried to start new Activity from NavigationView with OnNavigationItemSelectedListener(), but it won't work. I also have a Bottom NavigationView which works fine. I also tried with if else statement. In my opinion the problem is somewhere adding the listener to the Navigatopnview,because, the BottomNavigationView gets me the log info.

This how I approach the problem. I dont get any logs clicking on anything.

navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {

        @Override
        public boolean onNavigationItemSelected(@NonNull MenuItem item) {
            Log.i(TAG, "onNavigationItemSelected: " + item.getItemId());
            switch (item.getItemId()) {

                case R.id.nav_recent:
                    startActivity(new Intent(DashboardActivity.this, RecentActivity.class));
                    return true;

                case R.id.nav_offline:
                    Intent intentoffline = new Intent(DashboardActivity.this, OfflineActivity.class);
                    startActivity(intentoffline);
                    return true;

                case R.id.nav_trash:
                    Intent intenttrash = new Intent(DashboardActivity.this, TrashActivity.class);
                    startActivity(intenttrash);
                    return true;

                case R.id.nav_settings:
                    Intent intentsettings = new Intent(DashboardActivity.this, SettingsActivity.class);
                    startActivity(intentsettings);
                    return true;

                case R.id.nav_help:
                    Intent intenthelp = new Intent(DashboardActivity.this, HelpActivity.class);
                    startActivity(intenthelp);
                    return true;
            }
            drawerLayout.closeDrawer(GravityCompat.START);
            Log.i(TAG, "onNavigationItemSelected: nothing clicked");
            return false;
        }
    });

I have this XML layout file.

Answer 1

Move the NavigationView under the ConstraintLayout

Try this,

<androidx.drawerlayout.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:windowActionBar="false"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:openDrawer="start"
    android:id="@+id/drawerlayout"
    tools:ignore="InvalidId">

    <androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">

        <androidx.appcompat.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="0dp"
            android:layout_height="50dp"
            android:background="#383838"
            android:elevation="4dp"
            android:theme="?attr/actionBarTheme"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent">

            <SearchView
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                tools:layout_editor_absoluteX="16dp" />

        </androidx.appcompat.widget.Toolbar>

        <!-- Fragments Container -->

        <com.google.android.material.bottomnavigation.BottomNavigationView
            android:id="@+id/bottomnavigationview"
            android:layout_width="0dp"
            android:layout_height="55dp"
            android:background="#383838"

            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintHorizontal_bias="0.0"
            app:layout_constraintStart_toStartOf="parent"
            app:menu="@menu/navigation_menu" />
    </androidx.constraintlayout.widget.ConstraintLayout>

    <com.google.android.material.navigation.NavigationView
        android:id="@+id/navigationview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        app:menu="@menu/navigation_menu" />
