在android中的选定联系人上发送短信

Question

我一直在开发一个应用程序，它将从我的手机联系人中获取所有联系人，并向该列表中的选定联系人发送短信。我可以使用复选框获取所有联系人以供选择。我希望当我选择联系人并按下“发送消息”按钮时，消息会自动发送一些文本，例如“whats up！”等等

我需要帮助将 SMS 发送给多个联系人。

我的主要活动：

public class MainActivity extends  ListActivity {
    ArrayList<String> name1 = new ArrayList<String>();
    ArrayList<String> phno1 = new ArrayList<String>();
    protected static final String TAG = null;
    public String[] Contacts = {};
    public int[] to = {};
    public ListView myListView;


    //@SuppressWarnings("deprecation")
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        final Button done_Button = (Button) findViewById(R.id.done_Button);
        final Button clear_Button =(Button) findViewById(R.id.clear_Button);
        Cursor mCursor = getContacts();

        startManagingCursor(mCursor);
        ListAdapter adapter = new SimpleCursorAdapter(this, android.R.layout.simple_list_item_multiple_choice, mCursor,
                Contacts = new String[] {ContactsContract.Contacts.DISPLAY_NAME },
                to = new int[] { android.R.id.text1 });

        setListAdapter(adapter);
        myListView = getListView();
        myListView.setItemsCanFocus(false);
        myListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
        clear_Button.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                Toast.makeText(getApplicationContext(),"Selection Cleared", Toast.LENGTH_SHORT).show();
                ClearSelections();
            }
        });

        /** When 'Done' Button Pushed: **/

        done_Button.setOnClickListener(new View.OnClickListener() {

            public void onClick (View v){   
                String name = null;
                String number = null;
                long [] ids = myListView.getCheckedItemIds();
                for(long id : ids) {
                    Cursor contact = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, 
                            ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[] { id + "" }, null);
                    while(contact.moveToNext()){
                        name = contact.getString(contact.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
                        //name+=name;
                        number = contact.getString(contact.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                        //number+=number;
                    }
                    Toast.makeText(getApplicationContext(), "Name: " +name + "\n" + "Number: " + number , Toast.LENGTH_LONG).show();
                }
            }
        });
    }

    private void ClearSelections() {
        int count = this.myListView.getAdapter().getCount();
        for (int i = 0; i < count; i++) {
            this.myListView.setItemChecked(i, false);
        }
    }

    @SuppressWarnings("deprecation")
    private Cursor getContacts() {
        // Run query
        Uri uri = ContactsContract.Contacts.CONTENT_URI;
        String[] projection = new String[] { ContactsContract.Contacts._ID,
                                        ContactsContract.Contacts.DISPLAY_NAME};
        String selection = ContactsContract.Contacts.HAS_PHONE_NUMBER + " = '"
                + ("1") + "'";
        String[] selectionArgs = null;
        String sortOrder = ContactsContract.Contacts.DISPLAY_NAME
                + " COLLATE LOCALIZED ASC";

        return managedQuery(uri, projection, selection, selectionArgs,
                sortOrder);

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

public class sos extends AppCompatActivity {

Button sos;
ImageView add;
LinearLayout l1;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_sos);

    sos= findViewById(R.id.sos);
    add= findViewById(R.id.add);

    t1= findViewById(R.id.t1);

    sos.setOnClickListener(new View.OnClickListener() {

        public void onClick(View view) {
            String s="";
            s=t2.getText().toString();
            Intent intent = new Intent(Intent.ACTION_SENDTO,Uri.parse("sms:"+s));

您需要使用 SmsManager 来发送短信。以下是供您参考的代码：

SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage("phoneNo", null, "sms message", null, null); 

将此代码应用于您的发送消息按钮单击侦听器。
