Question

我正在使用Android默认导航抽屉，我想要在互联网上尝试搜索的所有活动的相同布局我有一些定制抽屉的想法，但没有在Android工作室默认抽屉。请帮助我。

navigation drawer.class：

JOIN joined_table ON (joined_table.column = table.column, joined_table.column2 = table.column2)
                                                        ^
                                             should be AND, not a comma

app_main.xml：

public class MainActivity extends AppCompatActivity
    implements NavigationView.OnNavigationItemSelectedListener {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main2);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    FloatingActionButton fab = (FloatingActionButton) 
    findViewById(R.id.fab);
    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Snackbar.make(view, "Replace with your own action", 
    Snackbar.LENGTH_LONG)
                    .setAction("Action", null).show();
        }
    });

    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);
}

app_bar_main.xml：

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout     
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">

<include
    layout="@layout/app_bar_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

<android.support.design.widget.NavigationView
    android:id="@+id/nav_view"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:fitsSystemWindows="true"
    app:headerLayout="@layout/nav_header_main"
    app:menu="@menu/activity_main_drawer" />

</android.support.v4.widget.DrawerLayout>

这里在app_bar_main布局中我想改变它包括layout =＆＃34; @ layout / content_main＆＃34;与我的活动或片段，以便我可以有相同的布局。

提前致谢。

创建一个仅包含NavigationDrawer的活动，然后OnItemSelected从NavigationDrawer调用您想要的每项活动。然后NavigationDrawer将在所有活动中可用。

另一个解决方案是使用MainActivity创建NavigationDrawer并创建其他Fragments而不是Activities。从Fragmnets拨打OnItemSelected NavigationDrawer。那里有很多例子。

修改

在您已定义navigationDrawer的活动中，执行以下操作。而不是为下一个布局创建新活动，创建片段并在navigationDrawer上的OnItemSelected上调用它们，如下所示：

navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() { // This method will trigger on item Click of navigation menu @Override public boolean onNavigationItemSelected(MenuItem menuItem) { //Checking if the item is in checked state or not, if not make it in checked state if (menuItem.isChecked()) menuItem.setChecked(false); else menuItem.setChecked(true); //Closing drawer on item click drawerLayout.closeDrawers(); //Check to see which item was being clicked and perform appropriate action switch (menuItem.getItemId()) { //Replacing the main content with ContentFragment Which is our Inbox View; case R.id.drawer_home: Intent intent=new Intent(HomeActivity.this, HomeActivity.class); startActivity(intent); overridePendingTransition(0, 0); finish(); return true; // For rest of the options we just show a toast on click case R.id.drawer_artist: android.support.v4.app.FragmentManager fragmentManager=getSupportFragmentManager(); android.support.v4.app.FragmentTransaction fragmentTransaction=fragmentManager.beginTransaction(); fragmentTransaction.replace(R.id.content_frame, new ArtistsFragment()); fragmentTransaction.addToBackStack(null); fragmentTransaction.commit(); return true; default: Toast.makeText(getApplicationContext(), "Somethings Wrong", Toast.LENGTH_SHORT).show(); return true; } } });

片段代码如下：

public class ArtistsFragment extends Fragment { public ArtistsFragment() { // Required empty public constructor } @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); } @Override public View onCreateView(final LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // Inflate the layout for this fragment View rootview= inflater.inflate(R.layout.fragment_artists, container, false); return rootview; }}

activity_main.xml中：

<android.support.v4.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:id="@+id/drawer_layout" android:layout_width="match_parent" android:elevation="4dp" android:layout_height="fill_parent" > <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <include android:id="@+id/tool_bar" layout="@layout/toolbar" android:layout_height="wrap_content" android:layout_width="match_parent" /> <FrameLayout android:id="@+id/content_frame" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@drawable/home"> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > </LinearLayout> </FrameLayout> </LinearLayout> <android.support.design.widget.NavigationView android:id="@+id/navigation" android:layout_width="wrap_content" android:layout_height="match_parent" android:layout_gravity="start" android:fitsSystemWindows="true" android:background="@drawable/bg_all" app:itemIconTint="@android:color/white" app:itemTextColor="@android:color/white" app:theme="@style/list_item_appearance" app:menu="@menu/drawer_menu" > </android.support.design.widget.NavigationView> </android.support.v4.widget.DrawerLayout>
