Adding a ListView layout to a layout file

<?xml version= "1.0" encoding= "Utf-8"? ><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"    android:paddingbottom= "@dimen/activity_vertical_margin"    android: paddingleft= "@dimen/activity_horizontal_margin"    android:paddingright= "@dimen/activity_horizontal_margin"    android:paddingtop= "@dimen/activity_vertical_margin"    tools:context= " Com.example.e5.duanxin.MainActivity ">    <listview        android:layout_width=" Fill_parent "        android: layout_height= "Fill_parent"        android:id= "@+id/lv"        android:layout_alignparenttop= "true"        Android: Layout_centerhorizontal= "true"/></relativelayout>

Create a new item layout file that can be edited according to your specific needs
<?xml version= "1.0" encoding= "Utf-8"? ><linearlayout xmlns:android= "Http://schemas.android.com/apk/res/android"Android:layout_width= "Match_parent"Android:layout_height= "Match_parent"android:orientation= "Horizontal" > <TextView android:layout_width= "0DP"Android:layout_weight= "1"Android:layout_height= "Wrap_content"Android:text= "Large Text"Android:id= "@+id/textview2"Android:textcolor= "#aa5599"/> <TextView android:layout_width= "0DP"Android:layout_weight= "1"Android:layout_height= "Wrap_content"Android:id= "@+id/textview"Android:text= "Body"Android:textcolor= "#FF5533"/></linearlayout>

ListView LV;    List<Person> Personsinfos;

Configuring permissions in the Androidmanifest.xml file

<uses-permission android:name= "Android.permission.READ_SMS" ></uses-permission>

　　

Declare a ListView layout and a list collection in mainactivity to hold the data

Get the ListView layout, and create a list collection object

Get the Contentresolver object

lv= (ListView) Findviewbyid (r.id.lv);
Personsinfos=new arraylist<person> ();

Contentresolver resolver= getcontentresolver ();

Find the URI of the mobile app "SMS"

Uri uri = uri.parse ("content://sms/");

Creates an object of the cursor class, puts the queried data into the cursor, and puts the data into the already built person class by MoveToNext ()
Finally close the cursor

Cursor cursor=resolver.query (URI,null,null,null,null);  while (Cursor.movetonext ()) {    person person =new person ();    Person.setbody (Cursor.getstring (Cursor.getcolumnindex ("Body"));    Person.settype (Cursor.getstring (Cursor.getcolumnindex ("Address"));    Personsinfos.add (person);}    Cursor.close ();

Creating the Baseadapter Parser

Create an inner class that inherits the Baseadapter interface and implements its abstract class

Private class Myadapter extends baseadapter{    @Override public    int GetCount () {        return personsinfos.size ();    }    @Override public    Object getItem (int position) {        return position;    }    @Override public    long getitemid (int position) {        return position;    }    @Override public    View getView (int position, view Convertview, ViewGroup parent) {        View view=view.inflate ( Mainactivity.this,r.layout.list_itme,null);        TextView tv_b= (TextView) view. Findviewbyid (R.id.textview);        TextView tv_t= (TextView) view. Findviewbyid (R.ID.TEXTVIEW2);        Tv_t.settext (Personsinfos.get (position). GetType ());        Tv_b.settext (Personsinfos.get (position). GetBody ());        return view;}    }

Load the adapter into the ListView layout

Lv.setadapter (new myadapter ());

Read the SMS database and put it in the ListView
