public class MainActivity extends Activity {
private ListView listView_main_info;
private TextView textView_empty;
private final static String Uri_sms = "content://sms";

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

listView_main_info = (ListView) findViewById(R.id.listView1);
textView_empty = (TextView) findViewById(R.id.textView_empty);

// 1. 获取ContentResolver
ContentResolver resolver = getContentResolver();

// 2.搜索数据ContentResolver.query().
Cursor cursor = resolver.query(Uri.parse(Uri_sms), new String[] {
"_id", "address", "body", "date" }, null, null, null);

SimpleCursorAdapter adapter = new SimpleCursorAdapter(this,
R.layout.sms_item, cursor, new String[] { "address", "body",
"date" }, new int[] { R.id.textView_address,
R.id.textView_body, R.id.textView_date }, 1);

listView_main_info.setAdapter(adapter);

listView_main_info.setEmptyView(textView_empty);
}

@Override

// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
