Android---47---簡訊群發功能，android---47---

提供一個帶列表的對話方塊供使用者選擇群發簡訊的收件者號碼，程式則使用了一個ArrayList<String>集合來儲存所有的收件者的號碼
為了實現群發功能，程式迴圈遍曆ArrayList中的號碼，依次向每個號碼傳送簡訊即可。

public class MainActivity extends Activity {EditText numbers, content;Button select, send;SmsManager smsManager;// 記錄列表ArrayList<String> sendlist = new ArrayList<String>();@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);smsManager = SmsManager.getDefault();numbers = (EditText) findViewById(R.id.numbers);content = (EditText) findViewById(R.id.content);select = (Button) findViewById(R.id.select);send = (Button) findViewById(R.id.send);send.setOnClickListener(new OnClickListener() {@SuppressWarnings("deprecation")@Overridepublic void onClick(View v) {// 一個一個去傳送簡訊for (String number : sendlist) {PendingIntent pi = PendingIntent.getActivity(MainActivity.this, 0, new Intent(), 0);smsManager.sendTextMessage(number, null, content.getText().toString(), pi, null);}Toast.makeText(MainActivity.this, "簡訊群發完成", 8000).show();}});// 選擇連絡人select.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) {// 查詢連絡人的電話號碼// ContentResolver.query(Uri uri, String[] projection, String// selection, String[] selectionArgs, String sortOrder)final Cursor cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null, null, null, null);BaseAdapter adapter = new BaseAdapter() {@Overridepublic int getCount() {// TODO Auto-generated method stubreturn cursor.getCount();}@Overridepublic Object getItem(int position) {// TODO Auto-generated method stubreturn position;}@Overridepublic long getItemId(int position) {// TODO Auto-generated method stubreturn position;}@Overridepublic View getView(int position, View convertView,ViewGroup parent) {cursor.moveToPosition(position);CheckBox rb = new CheckBox(MainActivity.this);// 擷取連絡人的電話號碼，並去掉中間的中劃線、空格String number = cursor.getString(cursor.getColumnIndex(CommonDataKinds.Phone.NUMBER)).replace("-", "").replace(" ", "");rb.setText(number);if (isChecked(number)) {rb.setChecked(true);}return rb;}};// 載入list.xml布局檔案對應的view介面View selectView = getLayoutInflater().inflate(R.layout.list,null);// 擷取selectView中名為list的ListView組件final ListView listView = (ListView) selectView.findViewById(R.id.list);listView.setAdapter(adapter);new AlertDialog.Builder(MainActivity.this).setView(selectView).setPositiveButton("確定",new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog,int which) {// 清空sendlist.clear();// 遍曆listView組件的每個清單項目for (int i = 0; i < listView.getCount(); i++) {CheckBox checkBox = (CheckBox) listView.getChildAt(i);// 如果該清單項目被勾選if (checkBox.isChecked()) {// 添加該清單項目的電話號碼sendlist.add(checkBox.getText().toString());}}numbers.setText(sendlist.toString());}}).show();}});}// 判斷某個號碼是否已在群發範圍內public boolean isChecked(String phone) {for (String s1 : sendlist) {if (s1.equals(phone)) {return true;}}return false;}}
