我想我用下面的code，推出通过拨号pad.I我的申请。对于拨号盘启动应用程序（在广播接收器）

I want to launch my application through dial pad.I am using the following code. For dial pad to launch application (in Broadcast receiver)

public class HiddenReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
try{

               // Toast.makeText(context,"Number Dialed",1).show();

                Intent serviceIntent = new Intent(context,MainActivity.class);
                    serviceIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    context.startActivity(serviceIntent);



                }
                catch(Exception e)
                {
                    Log.d(TAG, ""+e.getMessage());
                }

虽然经过我现在要启动中，我用我的主要活动拨号盘pressing键下面的

While pressing key through dial pad I want to launch my main activity in which I used the following

public class MainActivity extends Activity
{
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_hidden_receiver); 

         //Intent call here
        Intent intent=getIntent();
        String message = intent.getStringExtra(MainActivity.TELEPHONY_SERVICE);
         //text here

但是，当我preSS我的code其拨打的号码消失，但既不是拨号盘消失，也不MainActivity启动。 这怎么能问题得到解决？帮我出..... 谢谢你。

But when I press my code its dialed number disappear but neither dialer pad disappear nor MainActivity launches. how can this issues be resolved?Help me out..... Thanks.

推荐答案

使用了的BroadcastReceiver 如下：

public class MyOutgoingCallHandler extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
     // Extract phone number reformatted by previous receivers
    String phoneNumber = getResultData();
    if (phoneNumber == null) {
      // No reformatted number, use the original
      phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
    }

         if(phoneNumber.equals("1234")){ // DialedNumber checking.
        // My app will bring up, so cancel the broadcast
        setResultData(null);

        // Start my app
        Intent i=new Intent(context,MainActivity.class);
        i.putExtra("extra_phone", phoneNumber);
        i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);
         }

}

}

不要忘了在你的清单中注册该接收器

Don't forget to register this receiver in your manifest

    <receiver android:name="MyOutgoingCallHandler">
        <intent-filter >
            <action android:name="android.intent.action.NEW_OUTGOING_CALL"/>
        </intent-filter>
    </receiver>

此外，包括权限：

Also, include the permission:

<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS"/>

您MainActivity里面现在，如果你忽略了一些检查接收器，你会得到所拨打的号码，

Now, if you are ignoring the number checking in receiver, you'll get dialed number inside your MainActivity,

String phone=getIntent().getStringExtra("extra_phone");
    if(!phone.equals(null)){
        Toast.makeText(getBaseContext(), phone, Toast.LENGTH_LONG).show();
    }
