public class MyIntentContentDemo extends Activity {
private static final int PICK_CONTACT_SUBACTIVITY = 1;// 定义操作标记
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.setContentView(R.layout.main);
Uri uri = Uri.parse("content://contacts/people");// 连接URI
Intent intent = new Intent(Intent.ACTION_PICK, uri);// 指定Intent
super.startActivityForResult(intent, PICK_CONTACT_SUBACTIVITY);// 调用Intent
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case PICK_CONTACT_SUBACTIVITY:// 接收返回的数据
Uri ret = data.getData();// 单个数据Uri
String phoneSelection = ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ "=?";// 设置查询条件
String[] phoneSelectionArgs = { String.valueOf(ContentUris
.parseId(ret)) };// 查询参数
Cursor c = super.managedQuery(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
phoneSelection, phoneSelectionArgs, null);// 查询全部手机号码
StringBuffer buf = new StringBuffer() ;// 用于接收全部电话
buf.append("电话号码是：") ;
for (c.moveToFirst(); !c.isAfterLast(); c.moveToNext()) {// 循环取数据
buf.append(c.getString(c.getColumnIndex(
ContactsContract.CommonDataKinds.Phone.NUMBER)))
.append("、");// 取出电话号码
}
Toast.makeText(this, buf, Toast.LENGTH_LONG).show();// 显示信息
}
}
}
