DrawerLayout和toolbar的使用

onPostCreate()是Activity完全启动后的调用:在完全启动后的回调设置toolbar 然后在使用

AppCompatActivity 时style要设置为何appCompat相关的样式,不然会报错:

You need to use a Theme.AppCompat theme (or descendant) with this activity解决方法

 然后在使用注解框架时,如果是继承关系:不能两个地方都调用:则会出错

@Nullable doesn't work if Butterknife binds view from supersuperclass #389

 然后遇到的错是DrawerLayout的布局是尽量是设置:

    android:layout_width="match_parent"    android:layout_height="match_parent"不然也会报错:DrawerLayout must be measured with MeasureSpec.EXACTLY.解释: http://stackoverflow.com/questions/25864323/drawerlayout-must-be-measured-with-measurespec-exactly

Toolbar 使用的style:

<style name="ToolbarThemem" parent="AppTheme.PopupOverlay">

    <item name="android:background">?attr/colorPrimary</item>  设置背景颜色    <item name="android:layout_width">match_parent</item>       <item name="android:layout_height">wrap_content</item>    <item name="android:fitsSystemWindows">true</item>         <item name="android:minHeight">?attr/actionBarSize</item>   设置最小高度

<!-- android:textColorPrimary is the  color of the title text               in the Toolbar, in the Theme.AppCompat theme:  --><item name="android:textColorPrimary">@color/white</item>

<!-- android:textColorPrimaryInverse is the  color of the title       text in the Toolbar, in the Theme.AppCompat.Light theme:  --><item name="android:textColorPrimaryInverse">@color/white</item>

<!-- android:actionMenuTextColor is the color of the text of        action (menu) items in the Toolbar, at least in the        Theme.AppCompat theme.        For some reason, they already get the textColorPrimary        when running on API 21, but not on older versions of        Android, so this is only necessary to support older        Android versions.--><item name="actionMenuTextColor">@color/white</item><!-- android:textColorSecondary is the color of the menu       overflow icon (three vertical dots) --><item name="android:textColorSecondary">@color/white</item>

<!-- This would set the toolbar's background color,        but setting this also changes the popup menu's background,        even if we define popupTheme for our <Toolbar> -->

<item name="android:colorBackground">?attr/colorPrimary</item>

</style>

 AppTheme.PopupOverlay  是系统提供的一个默认Toolbar 的主题:

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

<!--  android:minHeight="?attr/actionBarSize"/>系统的配置-->

<android.support.v4.widget.DrawerLayout    android:id="@+id/drawer_layout"    android:layout_width="match_parent"    android:layout_height="match_parent"    xmlns:app="http://schemas.android.com/apk/res-auto"    android:fitsSystemWindows="true"    xmlns:android="http://schemas.android.com/apk/res/android">

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"        android:layout_width="match_parent"        android:layout_height="match_parent">    <android.support.v7.widget.Toolbar        android:id="@+id/msc_toolbar"      android:layout_height="wrap_content"        android:layout_width="match_parent"        android:layout_alignParentTop="true"        android:minHeight="?attr/actionBarSize"        app:popupTheme="@style/ThemeToolbar"        app:theme="@style/ThemeToolbar"        />

        <LinearLayout            android:orientation="vertical"            android:layout_width="match_parent"            android:layout_height="match_parent"            android:layout_marginTop="5dp"            android:layout_below="@id/msc_toolbar"            android:background="@color/white">

            <TextView                android:id="@+id/noThingsMessage"                android:layout_width="match_parent"                android:layout_height="wrap_content"                android:layout_margin="30dp"                android:textSize="20dp"                android:gravity="center_horizontal"                android:visibility="gone"/>

<ListView android:layout_width="match_parent"    android:layout_height="match_parent"    android:id="@+id/frame"/>

        </LinearLayout>    </RelativeLayout><android.support.design.widget.NavigationView    android:id="@+id/navigation_view"    android:layout_width="wrap_content"    android:layout_height="match_parent"    android:layout_gravity="start"    app:headerLayout="@layout/drawer_header"    android:background="?attr/colorPrimary"    app:itemIconTint="@color/white"    app:itemTextColor="@color/white"    app:menu="@menu/menu_main"    /></android.support.v4.widget.DrawerLayout>

//可以在onCreate() 或者onPostCreate() 方法中去显示 Toolbar 效果  :@Overrideprotected void onPostCreate(Bundle savedInstanceState) {    super.onPostCreate(savedInstanceState);

    mscToolbar = (Toolbar) findViewById(R.id.msc_toolbar);    navigationView = (NavigationView) findViewById(R.id.navigation_view);    drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);

    //TODO eventually remove if everything has the bar    if (mscToolbar != null) {        setSupportActionBar(mscToolbar);        getSupportActionBar().setTitle(title);        getSupportActionBar().setHomeAsUpIndicator(getResources().getDrawable(R.drawable.ic_menu_white_24dp));        getSupportActionBar().setDisplayHomeAsUpEnabled(true);        getSupportActionBar().setHomeButtonEnabled(true);

    }}

然后就是使用到了

navigationView.setNavigationItemSelectedListener(      new NavigationView.OnNavigationItemSelectedListener() {         @Override         public boolean onNavigationItemSelected(MenuItem menuItem) {            menuItem.setChecked(true);            drawerLayout.closeDrawers();            Intent intent = null;            switch (menuItem.getItemId()) {               case R.id.drawer_about:                  if (BaseActivity.this.getClass().equals(AboutActivity.class))                     return true;                  intent = new Intent(BaseActivity.this, AboutActivity.class);                  break;.......

//Toolbar 实现DrawerLayout 和图标互动的效果: 

ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(        this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);drawer.setDrawerListener(toggle);toggle.syncState();
