android - Activity 中未显示工具栏和操作栏

Question

我首先在我的应用程序中使用 Material 设计，我的问题是当我创建 Activity 时没有操作栏或工具栏但我有 Material 抽屉导航为什么它不像旧版本那样自动实现 Activity 布局:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">

     <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="New Text"
        android:id="@+id/textView4" />

</LinearLayout>

Activity : 包 fragment ；

import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.Menu;


  public class Noname1 extends ActionBarActivity{

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

   }
   @Override
   public boolean onCreateOptionsMenu(Menu menu) {

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

}`我的主题:

  <style name="AppTheme" parent="Theme.AppCompat.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/nliveo_green_colorPrimary</item>
    <item name="colorPrimaryDark">@color/nliveo_green_colorPrimaryDark</item>
    <item name="colorAccent">@color/nliveo_green_colorPrimary</item>
    <item name="android:textColorPrimary">@color/myTextPrimaryColor</item>
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>

    <item name="android:windowBackground">@color/myWindowBackground</item>
</style>

像这样创建一个 custom_toolbar.xml 文件:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:background="@color/nliveo_green_colorPrimary"
    android:layout_height="?android:attr/actionBarSize" />

将其包含在布局文件中的任意位置:

<include android:id="@+id/toolBar" layout="@layout/custom_toolbar"/>

在您的 onCreate 方法中:

public class Noname1 extends ActionBarActivity{

   @Override
    protected void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.test);
     Toolbar tb = (Toolbar)findViewById(R.id.toolBar);
     setSupportActionBar(tb);
   }
}

并保留您的 list 文件:

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/nliveo_green_colorPrimary</item>
    <item name="colorPrimaryDark">@color/nliveo_green_colorPrimaryDark</item>
    <item name="colorAccent">@color/nliveo_green_colorPrimary</item>
    <item name="android:textColorPrimary">@color/myTextPrimaryColor</item>
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>

    <item name="android:windowBackground">@color/myWindowBackground</item>
</style>

希望对您有所帮助!!!
