Customising NavigationView - Adding dynamic headerView, Android Support Design Library

Question

I tried the navigationView from the new android support design library. I want to have a dynamic headerview. Basically, my headerview will show something like quote of the day. I have like around 10 quotes and i want to randomly select a quote and display in a textview in the headerView. I also want to add onClick method for the headerView.

Right now, I don't see any possibilities of changing the headerview layout programmatically. Any suggestions to implement this?

Solution 1

first create header XML like lay_header.xml

<TextView
    android:id="@+id/tvThought"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

on your java file inflate this above header in a TextView. like

TextView headerView = (TextView) LayoutInflater.from(this).inflate(R.layout.lay_header, null);
headerView.setText("Your_thoght");

Now add it as a HeaderView

navView = (NavigationView) findViewById(R.id.navView);
navView.addHeaderView(headerView);

Thats it...

Solution 2

After the new support library update (23.1.1),

You could do this -

Add the headerview in the app:headerLayout="@layout/drawer_header" inside NavigationView.

Then, you can access it by,

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

or if you have multiple headers

navigationView.getHeaderCount()

Solution 3

TextView txt2;
txt2 = (TextView) navigationView.inflateHeaderView(R.layout.nav_header_main).findViewById(R.id.textView2);
txt2.setText("wow! It works like a charm");

Solution 4

create header layout take text view inside,

<TextView
                android:id="@+id/profile_email_text"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_alignLeft="@id/profile_image"
                android:layout_alignParentBottom="true"
                android:layout_toLeftOf="@id/expand_account_box_indicator"
                android:ellipsize="end"
                android:maxLines="1"
                android:paddingBottom="16dp"
                android:singleLine="true"
                android:clickable="true"
                android:onClick="onSelectText"
                android:text="[email protected]"
                android:textColor="@color/body_text_2_inverse"
                android:textSize="@dimen/text_size_medium" />

in onCreate,

((TextView) findViewById(R.id.profile_email_text)).setText("test");

create method onSelectText in your activity

public void onSelectText(View v){
        if(v.getId() == R.id.profile_email_text){
            Snackbar
                    .make(fab, "clicked on sub title", Snackbar.LENGTH_LONG)
                            //.setAction(R.string.snackbar_action, myOnClickListener)
                    .show();
            drawer_layout.closeDrawers();
        }
    }

Solution 5

You may add your custom header programmatically by calling addHeaderView on your navigationView, or define it in the layout file using app:headerLayout="@layout/myheader".
