Toolbar 是 Android 5.0 推出的一个 Material Design 风格的导航控件 ,用来取代之前的 Actionbar 。与 Actionbar 相比,Toolbar 明显要灵活的多。它不像 Actionbar 一样,一定要固定在Activity的顶部,而是可以放到界面的任意位置,看下官方文档介绍:
注意看着几部分:
- 1.设置导航栏图标;
- 2.设置App的logo;
- 3.支持设置标题和子标题;
- 4.支持添加一个或多个的自定义控件;
- 5.支持Action Menu;
首先,在布局文件 activity_normal_toolbar.xml.xml 中添加进 Toolbar 控件
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout 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.study.toolbardemo.NormalToolbarActivity"> <android.support.v7.widget.Toolbar android:id="@+id/toolbar_normal" android:layout_width="match_parent" android:layout_height="wrap_content" app:title="Title" app:titleTextColor="#ffffff" android:background="@color/colorPrimaryDark" app:subtitle="SubTitle" app:subtitleTextColor="#ffffff" app:logo="@mipmap/ic_launcher" app:navigationIcon="@mipmap/icon_back_32px"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:textColor="#ff0000" android:text="text"/> </android.support.v7.widget.Toolbar> </RelativeLayout>
然后新建一个menu文件夹,创建一个menu对应的xml文件
<?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto"> <item android:id="@+id/action_search" android:icon="@mipmap/ic_serach" android:title="@string/menu_search" app:showAsAction="ifRoom" /> <item android:id="@+id/action_notification" android:icon="@mipmap/notification" android:title="@string/menu_notification" app:showAsAction="ifRoom" /> <item android:id="@+id/action_item_one" android:title="@string/item_one" app:showAsAction="never" /> <item android:id="@+id/action_item_two" android:title="@string/item_two" app:showAsAction="never" /> </menu>
然后在Activity中设置几个属性即可,因为我们大部分设置都在xml中设置了,也可以动态设置
public class NormalToolbarActivity extends AppCompatActivity { private Toolbar mNormalToolbar; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_normal_toolbar); mNormalToolbar= (Toolbar) findViewById(R.id.toolbar_normal); initToolbar(); } private void initToolbar() { //设置menu mNormalToolbar.inflateMenu(R.menu.menu_normal); //设置menu的点击事件 mNormalToolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() { @Override public boolean onMenuItemClick(MenuItem item) { int menuItemId = item.getItemId(); if (menuItemId == R.id.action_search) { Toast.makeText(NormalToolbarActivity.this , R.string.menu_search , Toast.LENGTH_SHORT).show(); } else if (menuItemId == R.id.action_notification) { Toast.makeText(NormalToolbarActivity.this , R.string.menu_notification , Toast.LENGTH_SHORT).show(); } else if (menuItemId == R.id.action_item_one) { Toast.makeText(NormalToolbarActivity.this , R.string.item_one , Toast.LENGTH_SHORT).show(); } else if (menuItemId == R.id.action_item_two) { Toast.makeText(NormalToolbarActivity.this , R.string.item_two , Toast.LENGTH_SHORT).show(); } return true; } }); //设置左侧NavigationIcon点击事件 mNormalToolbar.setNavigationOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Toast.makeText(NormalToolbarActivity.this, "点击了左侧按钮", Toast.LENGTH_SHORT).show(); } }); } }
app:title="Title" app:titleTextColor="#ffffff" app:subtitle="SubTitle" app:subtitleTextColor="#ffffff" app:logo="@mipmap/ic_launcher" app:navigationIcon="@mipmap/icon_back_32px"
<!-- Base application theme. --> <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar"> <!-- Customize your theme here. --> <item name="colorPrimary">@color/colorPrimary</item> <item name="colorPrimaryDark">@color/colorPrimaryDark</item> <item name="colorAccent">@color/colorAccent</item> </style>
如果你不想改主题,可以在BaseActivity中添加这段代码,在onCreate中,setContentView之前
supportRequestWindowFeature(Window.FEATURE_NO_TITLE) 如果是继承Activity就应该调用requestWindowFeature(Window.FEATURE_NO_TITLE));
这里我只是简单的自定义了一下,起到一个抛砖引玉的作用吧。
贴出代码,有注释很详细的,基本上就是把Toolbar当成一个容器,往里面填充个布局
/** * Created by HFS on 2017/5/10. */ public class SimpleToolbar extends Toolbar { /** * 左侧Title */ private TextView mTxtLeftTitle; /** * 中间Title */ private TextView mTxtMiddleTitle; /** * 右侧Title */ private TextView mTxtRightTitle; public SimpleToolbar(Context context) { this(context,null); } public SimpleToolbar(Context context, AttributeSet attrs) { this(context, attrs,0); } public SimpleToolbar(Context context, AttributeSet attrs, int defStyleAttr) { super(context, attrs, defStyleAttr); } @Override protected void onFinishInflate() { super.onFinishInflate(); mTxtLeftTitle = (TextView) findViewById(R.id.txt_left_title); mTxtMiddleTitle = (TextView) findViewById(R.id.txt_main_title); mTxtRightTitle = (TextView) findViewById(R.id.txt_right_title); } //设置中间title的内容 public void setMainTitle(String text) { this.setTitle(" "); mTxtMiddleTitle.setVisibility(View.VISIBLE); mTxtMiddleTitle.setText(text); } //设置中间title的内容文字的颜色 public void setMainTitleColor(int color) { mTxtMiddleTitle.setTextColor(color); } //设置title左边文字 public void setLeftTitleText(String text) { mTxtLeftTitle.setVisibility(View.VISIBLE); mTxtLeftTitle.setText(text); } //设置title左边文字颜色 public void setLeftTitleColor(int color) { mTxtLeftTitle.setTextColor(color); } //设置title左边图标 public void setLeftTitleDrawable(int res) { Drawable dwLeft = ContextCompat.getDrawable(getContext(), res); dwLeft.setBounds(0, 0, dwLeft.getMinimumWidth(), dwLeft.getMinimumHeight()); mTxtLeftTitle.setCompoundDrawables(dwLeft, null, null, null); } //设置title左边点击事件 public void setLeftTitleClickListener(OnClickListener onClickListener){ mTxtLeftTitle.setOnClickListener(onClickListener); } //设置title右边文字 public void setRightTitleText(String text) { mTxtRightTitle.setVisibility(View.VISIBLE); mTxtRightTitle.setText(text); } //设置title右边文字颜色 public void setRightTitleColor(int color) { mTxtRightTitle.setTextColor(color); } //设置title右边图标 public void setRightTitleDrawable(int res) { Drawable dwRight = ContextCompat.getDrawable(getContext(), res); dwRight.setBounds(0, 0, dwRight.getMinimumWidth(), dwRight.getMinimumHeight()); mTxtRightTitle.setCompoundDrawables(null, null, dwRight, null); } //设置title右边点击事件 public void setRightTitleClickListener(OnClickListener onClickListener){ mTxtRightTitle.setOnClickListener(onClickListener); } }
贴下xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout 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" android:orientation="vertical" tools:context="com.study.toolbardemo.CustomToolbarActivity"> <com.study.toolbardemo.widget.SimpleToolbar android:id="@+id/simple_toolbar" android:layout_width="match_parent" android:layout_height="wrap_content" android:minHeight="?attr/actionBarSize" android:background="?attr/colorPrimaryDark" android:fitsSystemWindows="true" app:contentInsetLeft="0dp" app:contentInsetStart="0dp"> <TextView android:id="@+id/txt_left_title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="10dp" android:drawableLeft="@mipmap/icon_back_32px" android:gravity="center" android:singleLine="true" android:text="返回" android:textColor="#ffffff" android:textSize="16sp" android:visibility="visible"/> <TextView android:id="@+id/txt_main_title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:singleLine="true" android:text="标题" android:textColor="@android:color/white" android:textSize="20sp" android:visibility="visible"/> <TextView android:id="@+id/txt_right_title" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="right" android:layout_marginRight="10dp" android:drawableRight="@mipmap/icon_plus" android:gravity="center" android:textColor="#ffffff" android:textSize="16sp" android:visibility="visible"/> </com.study.toolbardemo.widget.SimpleToolbar> </LinearLayout>
这里面有几个地方注意下:
1.往Toolbar里面填充View的时候,外面最好不要有其他的ViewGroup,如LinearLayout,因为如果外面再包一层的话,Title就不会居中了,那样不太符合我们的设计;
2.app:contentInsetLeft=”0dp” app:contentInsetStart=”0dp”这两个是设置Toolbar左右间隔的,如果不设置的话,默认有个默认值
贴出来style
<!-- Base application theme. --> <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"> <!-- Customize your theme here. --> <item name="colorPrimary">@color/colorPrimary</item> <item name="colorPrimaryDark">@color/colorPrimaryDark</item> <item name="colorAccent">@color/colorAccent</item> <item name="windowActionBar">false</item> <item name="windowNoTitle">true</item> </style>
这里的style你可以这样写,也可以直接用NoActionBar那个主题,效果基本上一样。
