ActionBar简单使用

1. 引入v7的依赖库
2. Activity继承ActionBarActivity或者继承AppCompatActivity
3. 修改主题样式

Theme.Appcompat.Light

​

// 修改actionbar背景颜色

<item name="colorPrimary">@color/colorPrimary</item>

//修改状态栏颜色5.0以上

<item name="colorPrimaryDark">@color/colorPrimaryDark</item>

// 修改控件的主体颜色

<item name="colorAccent">@color/colorAccent</item>

1. 添加actionbar上的按钮

在res/menu/xxxxx.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"

     xmlns:yourapp="http://schemas.android.com/apk/res-auto" >

   <!-- Search, should appear as action button -->

   <item android:id="@+id/action_search"

         android:icon="@drawable/ic_action_search"

         android:title="@string/action_search"

         yourapp:showAsAction="ifRoom"  />

   ...

</menu>

1. 引入menu中的xml

@Override

public boolean onCreateOptionsMenu(Menu menu) {

   // Inflate the menu items for use in the action bar

   MenuInflater inflater = getMenuInflater();

   inflater.inflate(R.menu.main_activity_actions, menu);

   return super.onCreateOptionsMenu(menu);

}

1. Drawerlayout使用

<?xml version="1.0" encoding="utf-8"?>

<android.support.v4.widget.DrawerLayout

   xmlns:android="http://schemas.android.com/apk/res/android"

   xmlns:tools="http://schemas.android.com/tools"

   android:layout_width="match_parent"

   android:layout_height="match_parent"

   android:orientation="horizontal"

   >

​

   <!--内容-->

   <LinearLayout

       android:layout_width="match_parent"

       android:layout_height="match_parent">

​

       <TextView

           android:layout_width="wrap_content"

           android:layout_height="wrap_content"

           android:text="Hello World!"/>

   </LinearLayout>

​

   <!--菜单-->

   <FrameLayout

       android:layout_width="match_parent"

       android:layout_height="match_parent"

       android:layout_gravity="start"

       android:background="#f00"/>

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

1. ActionBar&DrawerLayout联动

   1. ActionBarDrawerToggle

   // 显示返回箭头 或者 home按钮

          ActionBar actionBar = getSupportActionBar();

          actionBar.setDisplayHomeAsUpEnabled(true);

          mDrawerLayout = (DrawerLayout) findViewById(R.id.drawerlayout);

          //ActionBarDrawerToggle

   ​

          mActionBarDrawerToggle = new ActionBarDrawerToggle(this,mDrawerLayout, R.string.open,R.string.close);

          mDrawerLayout.addDrawerListener(mActionBarDrawerToggle);

          //同步状态

          mActionBarDrawerToggle.syncState();

 

/actionbar上按钮的点击/

@Override
   public boolean onOptionsItemSelected(MenuItem item) {
       if (mActionBarDrawerToggle.onOptionsItemSelected(item)){
           return true;//消费
       }

  /*     int itemId = item.getItemId();
       if (itemId == android.R.id.home){
           Toast.makeText(MainActivity.this, "home按钮被点击了", Toast.LENGTH_SHORT).show();
       }*/

       return super.onOptionsItemSelected(item);
   }
