android - 工具栏从顶部切割。如何显示完整的工具栏？

Question

我正在添加 Material 抽屉Material Drawer并制作了一个方法 addNavigationDrawer 来添加抽屉导航并在我从 Firebase Firestore 数据库中获取用户详细信息后调用该方法(您可以在 OnCreate 方法下的 Auth Listener 中找到它)但是在第一次打开此 Activity 时，操作栏被切割为你可以在图像中看到但是当我将它最小化并再次打开它时，它工作得非常好。请建议该怎么做？

这里是Activity的完整代码

public class Main2Activity extends AppCompatActivity {

ProfileInformationDialog profileInformationDialog;

FirebaseAuth firebaseAuth;
FirebaseAuth.AuthStateListener authStateListener;
FirebaseFirestore db;
DocumentReference documentReference;

Button button;
GoogleApiClient googleApiClient;

/*@BindView(R.id.toolbar)
Toolbar toolbar;*/

ProgressDialog progressDialog;

String user_name,shop_name;
Toolbar toolbar;

Drawer result;

AccountHeader headerResult;


@Override
public void onStart()
{
    GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestEmail()
            .build();

    googleApiClient = new GoogleApiClient.Builder(this)
            .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
            .build();

    googleApiClient.connect();
    super.onStart();
    firebaseAuth.addAuthStateListener(authStateListener);
}

Answer 1

step 1 add this style to value/style

 <style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
 </style>

step 2 add this style to value/style-v21

<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="android:statusBarColor">@android:color/transparent</item>
</style>

step 3 and change your layout

<?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:layout_width="match_parent"
        android:id="@+id/drawer_layout"
        android:layout_height="match_parent"
        android:fitsSystemWindows="true"
        tools:openDrawer="start"> 

       <android.support.design.widget.CoordinatorLayout 
              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:layout_width="match_parent"
              android:layout_height="match_parent"
             tools:context="com.visky.railway.sec.ui.activity.MainActivity">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:popupTheme="@style/AppTheme.PopupOverlay" />

    </android.support.design.widget.AppBarLayout>

    <RelativeLayout
         android:layout_width="match_parent"
          android:layout_height="match_parent"
          app:layout_behavior="@string/appbar_scrolling_view_behavior">

       -----------here your layout content---------------

    </RelativeLayout>
 </android.support.design.widget.CoordinatorLayout>

 <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>

step 4 add theme to manifest.xml

   <activity
      android:name=".MainActivity"
      android:label="@string/app_name"
      android:theme="@style/AppTheme.NoActionBar"/>
