第Android自定義ToolBar并實現(xiàn)沉浸式的方法publicCustomToolBarsetCenterTitleWithImg(CharSequencetext,Drawabledrawable,booleancenter){

Contextcontext=this.getContext();

if(this.mCenterTitle==null){

this.mCenterTitle=newTextView(context);

if(this.mCenterTitle.getVisibility()!=VISIBLE){

mCenterTitle.setVisibility(VISIBLE);

if(this.mCenterIcon==null){

this.mCenterIcon=newImageView(context);

}else{

if(mCenterIcon.getVisibility()!=VISIBLE){

mCenterIcon.setVisibility(VISIBLE);

mCenterTitle.setTextSize(18);

mCenterTitle.setTextColor(getResources().getColor(R.color.black));

mCenterTitle.setText(text);

mCenterIcon.setImageDrawable(drawable);

returnthis;

publicvoidsetCenterTitleWithImgOnClickListener(OnClickListenerlistener){

if(mCenterTitle!=null){

((View)mCenterTitle.getParent()).setOnClickListener(listener);

}

2、自定義Toolbar使用

1）、res/layout創(chuàng)建布局文件

xmlversion="1.0"encoding="utf-8"

FrameLayoutxmlns:android="/apk/res/android"

xmlns:app="/apk/res-auto"

android:layout_width="match_parent"

android:layout_height="wrap_content"

com.ktx.view.CustomToolBar

android:id="@+id/toolbar"

android:layout_width="match_parent"

android:layout_height="actionBarSize"

android:background="@android:color/white"

app:popupTheme="@style/ThemeOverlay.AppCompat.Light"

app:titleTextColor="@android:color/black"/

/FrameLayout

2）、在布局中使用

xmlversion="1.0"encoding="utf-8"

layoutxmlns:android="/apk/res/android"

xmlns:app="/apk/res-auto"

xmlns:binding="/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）、代碼中使用

a、初始化：

mBinding.root.toolbar.setNavigationIcon(R.mipmap.register_close)

mBinding.root.toolbar.setMyCenterTitle(getString(R.string.register),true)

mBinding.root.toolbar
