Android Combat Simple Tutorial-the 14th gun (introduction swipemenulistview-simple implementation similar to the sliding deletion effect of QQ)

1. Implementing the Layout file Main.xml

<relativelayout xmlns:android= "http://schemas.android.com/apk/res/android"    xmlns:tools= "http// Schemas.android.com/tools "    android:layout_width=" match_parent "    android:layout_height=" Match_parent "    tools:context= "${relativepackage}.${activityclass}" >    < Com.baoyz.swipemenulistview.SwipeMenuListView        android:id= "@+id/listview"        android:layout_width= "Match_ Parent "        android:layout_height=" Match_parent "/></relativelayout>

Layout file for item in 2.listview:

<relativelayout xmlns:android= "http://schemas.android.com/apk/res/android"    xmlns:tools= "http// Schemas.android.com/tools "    android:layout_width=" match_parent "    android:layout_height=" Wrap_content "    android:padding= "8DP" >    <imageview        android:id= "@+id/iv_icon"        android:layout_width= "50DP"        android:layout_height= "50DP"        android:src= "@drawable/ic_launcher"/>    <textview        android: Id= "@+id/tv_name"        android:layout_width= "wrap_content"        android:layout_height= "Wrap_content        " Android:layout_centervertical= "true"        android:layout_marginleft= "10DP"        android:layout_torightof= "@+id /iv_icon "        android:text=" name "        android:textcolor=" @android: Color/black "        android:textsize=" 18SP "/ ></RelativeLayout>

3. Implement activity:

Getdisplaymetrics ());}}

4. Running the example:

Click Delete to delete the selected item.

Summary 1.

public void Create (Swipemenu menu)

Create a sliding menu
2.

Mlistview.setmenucreator (creator);
