java– 导航抽屉和android数据绑定

概述对不起我的英语不好.我需要使用Android数据绑定处理按钮单击.我在content_main.xml中包含了数据绑定.<data><variablename="temp"type="skubyev.anton.navigationdrawer.DataBindingClass.MainActivityData"/>

对不起我的英语不好.我需要使用Android数据绑定处理按钮单击.我在content_main.xml中包含了数据绑定.

    <data>            <variable                name="temp"                type="skubyev.anton.navigationdrawer.DataBindingClass.MainActivityData" />            <variable                name="presenter"                type="skubyev.anton.navigationdrawer.DataBindingClass.MainActivityPresenter"/>        </data>....     <androID.support.design.Widget.floatingActionbutton                androID:onClick="@{() -> presenter.onShowData(temp)}"

但是MainActivity.java

@OverrIDe    protected voID onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        ContentMainBinding binding = DataBindingUtil.setContentVIEw(this, R.layout.content_main);        MainActivityPresenter mainActivityPresenter = new MainActivityPresenter(this);        MainActivityData mainActivityData = new MainActivityData("Иди нахуй");        binding.setTemp(mainActivityData);        binding.setPresenter(mainActivityPresenter);        setContentVIEw(R.layout.activity_main);.... @OverrIDe    public voID showData(MainActivityData mainActivityData) {        String textForRecognition = mainActivityData.getTextForRecognition();        Toast.makeText(this, textForRecognition, Toast.LENGTH_SHORT).show();    }

我想要showData运行,然后点击content_main中的floatingActionbutton.但showData – 类MainActivity中的函数.因此,据我所知,当您单击content_main.xml上的按钮时,不会调用它.我该怎么办？创建一个单独的类ContentActivity.java whith函数showData.

我只想要MainActivity.java负责处理content_main上的点击.如何正确实现？

解决方法:

在Activity中添加此代码用于数据绑定

@OverrIDeprotected voID onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    ActivityMainBinding activityMainBinding = DataBindingUtil.setContentVIEw(this, R.layout.activity_main);    Mainviewmodel mainviewmodel = viewmodelProvIDers.of(this).get(Mainviewmodel.class);    activityMainBinding.setHandlers(handlers);    activityMainBinding.setviewmodel(mainviewmodel);    Toolbar toolbar = findVIEwByID(R.ID.toolbar);    toolbar.setTitle("HOME");    DrawerLayout drawer = activityMainBinding.drawerLayout;    ActionbarDrawerToggle toggle = new ActionbarDrawerToggle(            this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);    drawer.addDrawerListener(toggle);    toggle.syncState();    NavigationVIEw navigationVIEw = activityMainBinding.navVIEw;    NavheaderMainBinding navheaderMainBinding = DataBindingUtil.inflate(getLayoutInflater(), R.layout.nav_header_main, activityMainBinding.navVIEw, true);    navheaderMainBinding.navEmail.setText(session.getFacilityEmail());    navheaderMainBinding.navname.setText(session.getFacilityname());    navigationVIEw.setNavigationItemSelectedListener(this);}

在nav_hader_main.xml中你必须是这样的

<?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"><data>    <variable        name="navigationheader"        type="com.nudge.gurukul.vIEw.activitIEs.MainActivity" />    <import type="androID.vIEw.VIEw" /></data><linearLayout    androID:layout_wIDth="match_parent"    androID:layout_height="@dimen/nav_header_height"    androID:background="@drawable/sIDe_nav_bar"    androID:gravity="bottom"    androID:orIEntation="vertical"    androID:paddingleft="@dimen/activity_horizontal_margin"    androID:paddingtop="@dimen/activity_vertical_margin"    androID:paddingRight="@dimen/activity_horizontal_margin"    androID:paddingBottom="@dimen/activity_vertical_margin"    androID:theme="@style/themeOverlay.AppCompat.Dark">    <ImageVIEw        androID:ID="@+ID/imageVIEw"        androID:layout_wIDth="wrap_content"        androID:layout_height="wrap_content"        androID:contentDescription="@string/nav_header_desc"        androID:paddingtop="@dimen/nav_header_vertical_spacing"        app:srcCompat="@mipmap/app_logo_round" />    <TextVIEw        androID:ID="@+ID/nav_name"        androID:layout_wIDth="match_parent"        androID:layout_height="wrap_content"        androID:paddingtop="@dimen/nav_header_vertical_spacing"        androID:textAppearance="@style/TextAppearance.AppCompat.Body1" />    <TextVIEw        androID:ID="@+ID/nav_email"        androID:layout_wIDth="wrap_content"        androID:layout_height="wrap_content" /></linearLayout>

这应该按照您的例外情况,您可以将文本和图像绑定到导航抽屉
