Android custom ToolBar and immersive

Keywords: Android xml encoding github

;


The ToolBar is Android Five A new navigation control is introduced to replace the previous ActionBar. Because of its high customizability, flexibility, Material Design style and other advantages, more and more apps also use toolbars.
Immersive status bar is from android Kitkat (Android Four point four )In the beginning, it can be set to the same color as the top of APP, which makes the whole interface switch to the same style as APP when switching APP.

Dependency package:

  Toolbar, implementation 'androidx.appcompat:appcompat:1.1.0'
Immersion, implementation ' com.gyf.immersionbar :imm ersionbar:3.0.0 '

1. Custom Toolbar step: s

1) , definitions / values/styles.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="TextAppearance_TitleBar_Title" parent="TextAppearance.AppCompat.Toolbar.Title">
    ...
    </style>

    <style name="TextAppearance_TitleBar_subTitle" parent="TextAppearance.AppCompat.Toolbar.Subtitle">
      ....
    </style>
</resources>

2) , custom toolbar inheritance androidx.appcompat.widget.Toolbar

2. Custom Toolbar usage

1) , res/layout create layout file

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

2) , use in layout

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:binding="http://schemas.android.com/tools">
    <data>
        <variable
            name="viewModel"
            type="com.android.playandroid.viewmodel.LoginViewModel" />
    </data>
    <androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@color/bkg"
        android:orientation="vertical">

        <include
            layout="@layout/title_layout"
            app:layout_constraintLeft_toLeftOf="parent"
            app:layout_constraintTop_toTopOf="parent" />
         ...
    </androidx.constraintlayout.widget.ConstraintLayout>

</layout>

3) , used in code

#####a. initialization:

    mBinding.root.toolbar.setNavigationIcon(R.mipmap.register_close)
    mBinding.root.toolbar.setMyCenterTitle(getString(R.string.register), true)
    mBinding.root.toolbar.setMySettingText(getString(R.string.login))

#####b. click event:

   mBinding.root.toolbar.setNavigationOnClickListener {
        ....
    }
    mBinding.root.toolbar.setSettingTextOnClickListener {
       ...
}

4) , immersive, set toolbar background color and text color, generally written in the base class

 protected open fun initImmersionBar() {
        //Initialize in BaseActivity
        mImmersionBar = ImmersionBar.with(this)
        if (toolbar != null) {
            mImmersionBar.titleBar(toolbar)
        }
        mImmersionBar.statusBarDarkFont(true)
    //    mImmersionBar.keyboardEnable(true).navigationBarWithKitkatEnable(false).init()
      //  mImmersionBar.init()
        
       ImmersionBar.with(this).init()
    }

Google's native effect, needless to say, can achieve such an effect

be careful:

1. Configure the toolbar style of the entire app at / value/styles.xml Document modification code

 <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
    
        <item name="colorPrimary">@android:color/white</item>
        <item name="colorPrimaryDark">@android:color/white</item>
        <item name="colorAccent">@android:color/white</item>

      ...

    </style>

####2. How to display navigationIcon in the center of the toolbar after modifying the height of the toolbar?
   just set as follows: android:minHeight="@dimen/toolbar_height"

3. toolbar layout file location

   if you create this file in the commonlibrary directory, you need to copy it under the app, because kotlin Android extensions cannot reference the layout file in the commonlibrary directory when using toolbar in the app.
