Question

我正在开发一个Android项目，我想创建一个拦截入站呼叫的应用程序。如何在联系人列表中分配一个复选框，以便能够选择多个联系人一次？

这是我的代码：

//主要活动

    public class MainActivity extends Activity {
        @Override
       public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        add = (Button)findViewById(R.id.add_reminder);
        manage =  (Button)findViewById(R.id.manage_reminders);
        add.setOnClickListener(this);
        manage.setOnClickListener(this);


    }
    public void onClick(View v) {
        switch(v.getId())
        {
        case R.id.manage_reminders:

            break;
        case R.id.add_reminder:
             Intent intent = new Intent(Intent.ACTION_PICK);
              intent.setType(ContactsContract.Contacts.CONTENT_TYPE);
              startActivityForResult(intent, PICK_CONTACT);


            break;

        }


    }
     public void onActivityResult(int requestCode, int resultCode, Intent intent)
        {

          if (requestCode == PICK_CONTACT)
          {        
              Cursor cursor =  managedQuery(intent.getData(), null, null, null, null);
              cursor.moveToNext();
              String contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
               String  name = cursor.getString(cursor.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));

              Toast.makeText(this, "Contect LIST  =  "+name, Toast.LENGTH_LONG).show();
          }
        }//onActivityResult

}

看看这里：http://www.krvarma.com/2010/08/detecting-incoming-and-outgoing-calls-in-android/

只需制作一个侦听的BroadcastReceiver：

android.intent.action.PHONE_STATE

如果手机状态为“振铃”，则有来电。

TelephonyManager.EXTRA_STATE

像：

public class IncomingCallReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
            Bundle bundle = intent.getExtras();

            if(null == bundle)
                    return;

            String state = bundle.getString(TelephonyManager.EXTRA_STATE);

            if(state.equalsIgnoreCase(TelephonyManager.EXTRA_STATE_RINGING))
            {
                    String phonenumber = bundle.getString(TelephonyManager.EXTRA_INCOMING_NUMBER);

                    Log.i("IncomingCallReceiver","Incoming Number: " + phonenumber);
            }
    }
}

现在电话号码将以logcat打印。

显示带复选框的联系人列表？
