1.注意：根据不同分辨率写Value,layout,drawable。从而做到适配
2.布局
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:custom="http://schemas.android.com/apk/res-auto" xmlns:app="http://schemas.android.com/tools" android:orientation="horizontal" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingTop="@dimen/basicPaddingSize"> <android.support.v7.widget.RecyclerView android:id="@+id/recyclerview_category" android:layout_width="@dimen/category_layout_width" android:layout_height="fill_parent" android:background="@color/white" > </android.support.v7.widget.RecyclerView> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" android:layout_marginLeft="2dp" > <com.daimajia.slider.library.SliderLayout android:id="@+id/slider" android:layout_width="match_parent" android:layout_height="180dp" custom:pager_animation="Accordion" custom:auto_cycle="true" custom:indicator_visibility="visible" custom:pager_animation_span="1100" /> <com.cjj.MaterialRefreshLayout android:id="@+id/refresh_layout" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_marginTop="10dp" app:overlay="false" app:wave_show="false" app:progress_colors="@array/material_colors" app:wave_height_type="higher" app:progress_show_circle_backgroud="false" > <android.support.v7.widget.RecyclerView android:id="@+id/recyclerview_wares" android:layout_width="match_parent" android:layout_height="match_parent"> </android.support.v7.widget.RecyclerView> </com.cjj.MaterialRefreshLayout> </LinearLayout></LinearLayout>
2.一级菜单Adapter
