使用android设计支持库将onClickListener添加到导航视图标题

Question

我想在导航视图标题的项目中添加onClickListener，例如更改TextView文本或为ImageView设置图像。

Answer 1

In your activity_main.xml layout add navigation drawer code.

<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:orientation="vertical">

<include layout="@layout/toolbar"/>

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

    <FrameLayout
        android:id="@+id/containerView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"></FrameLayout>

    <android.support.design.widget.NavigationView
        android:id="@+id/navigationView"
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:layout_marginTop="-24dp"
        app:headerLayout="@layout/drawer_header"
        app:itemTextColor="@color/black"
        app:menu="@menu/nav_menu"/>

</android.support.v4.widget.DrawerLayout>

and adder your drawer_header.xml in the layout directory

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">

<TextView
    android:clickable="true"
    android:paddingTop="20dp"
    android:id="@+id/textView5"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="My header"
    android:textAppearance="?android:attr/textAppearanceLarge"/>

add nav_menu.xml to your menu directory

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

<group
    android:id="@+id/main_features"
    android:checkableBehavior="single">
    <item
        android:id="@+id/idHome"
        android:title="Home" />

    <item
        android:id="@+id/favorite"
        android:title="Favorites" />


   <item
        android:id="@+id/idSettings"
        android:title="Settings" />


</group>

in your MainActivity.java listen to the clicks

 DrawerLayout mDrawerLayout;
 NavigationView mNavigationView;
 TextView header;

then initialize them in your onCreate():

 mDrawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
 mNavigationView = (NavigationView) findViewById(R.id.navigationView);
  header = (TextView) findViewById(R.id.textView5);
    header.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(getBaseContext(),"Calling Header", Toast.LENGTH_LONG).show();
        }
    });

Update: 27/10/2015

with the update on support library adding header to the navigation view in xml is not working, may be its a bug.

to add a header view inflate the view as navigation view header in java.

mNavigationView.inflateHeaderView(R.layout.layout_header_profile);

hope it will help. Happy Coding...

Answer 2

You can do this -

View header = navigationView.getHeaderView(0);
TextView text = (TextView) header.findViewById(R.id.textView);

or if you have multiple headers:

navigationView.getHeaderCount();

Set onClickListener in XML on your view like so:

android:onClick="onLabelClick"

Then in your activity

public void onLabelClick(View view) {
    // do stuff :)
}
