java - How to implement ListFragment and NavigationDrawerFragment -
i want build android application fragment contains list of option , if click on 1 of option, can see, fragment other option.
so build this:
activity_main.xml
<?xml version="1.0" encoding="utf-8"?> <android.support.v4.widget.drawerlayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/drawer_layout" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".activity.mainactivity" tools:ignore="mergerootframe" > <framelayout android:id="@+id/container" android:layout_width="match_parent" android:layout_height="match_parent" /> <linearlayout android:layout_width="480dp" android:layout_height="match_parent" android:layout_gravity="start" tools:layout="@layout/fragment_navigation_drawer" > <listview android:id="@+id/left_list" android:layout_width="240dp" android:layout_height="match_parent" android:background="#6dc659" android:foreground="@color/white"> </listview> <fragment android:id="@+id/navigation_drawer" android:name="it.eresult.decipher.fragment.navigationdrawerfragment" android:layout_width="240dp" android:layout_height="match_parent" android:layout_gravity="start" tools:layout="@layout/fragment_navigation_drawer" /> </linearlayout> </android.support.v4.widget.drawerlayout> this mainactivity.java

instead, want see left menu, , if click on 1 items, see right menu
