利用ContentResolver訪問者獲取手機短信信息，在此記錄一下，一遍以后查詢。
首先看一下結果，結果如下：
activity_message.xml類:
<LinearLayout xmlns:android/119723.html">android/233032.html">android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_message" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" tools:context="com.example.android_25.MessageActivity"> <ListView android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/lv_message" > </ListView></LinearLayout>
activity_xs.xml類
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_xs" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" tools:context="com.example.android_25.XsActivity"><TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/tv_name" /> <TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:id="@+id/tv_telephone" /></LinearLayout>
MessageActivity類：
public class MessageActivity extends AppCompatActivity { private ListView lv_message; private ContentResolver cr; private ArrayList<Map<String, Object>> datalistView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_message); //獲得短信的ID lv_message = (ListView) findViewById(R.id.lv_message); //得到訪問者ContentResolver cr = getContentResolver(); //定義一個接收短信的集合 datalistView = new ArrayList<>(); Uri uri = Uri.parse("content://sms/"); Cursor cursor = cr.query(uri, null, null, null, null); while (cursor.moveToNext()) { String body = cursor.getString(cursor.getColumnIndex("body")); int address = cursor.getInt(cursor.getColumnIndex("address")); //將號碼和短信內容放入Map集合中 Map<String, Object> map = new HashMap<>(); map.put("images", address+""); map.put("titles", body); datalistView.add(map); } SimpleAdapter adapter = new SimpleAdapter(this, datalistView, R.layout.activity_xs, new String[]{"images", "titles"}, new int[]{R.id.tv_name, R.id.tv_telephone}); lv_message.setAdapter(adapter); }}以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持VEVB武林網。
