我一直在寻找那么多而且我找不到解决方案。
我的应用程序一直拨打一个号码,当它收到一个确切号码的来电时,它会停止(死掉)。 我的想法是:
所以,我想使用BroadcastReceiver来杀死Activity,但我还没有找到任何解决方案。为了尝试另一件事,我尝试发送Intent with Extras但Extras已变为null。
我愿意使用任何解决它的解决方案!
非常感谢你!
更新代码以推荐Kurtis Nusbaum 我看到问题出在服务时,所以我把所有代码
这是我的代码:
package com.comunicacio;
import android.app.Activity;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.util.Log;
public class Comunicacio extends Activity {
IntentFilter filter;
private BroadcastReceiver receiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
Log.i("BYE", "OOOOOOOOOOOOK");
finish();
}
};
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
filter = new IntentFilter();
filter.addAction("com.comunicacio.FINALITZAR");
startService(new Intent(this, Servicio.class));
}
@Override
protected void onResume() {
super.onResume();
registerReceiver(receiver, filter);
}
@Override
protected void onPause() {
super.onPause();
unregisterReceiver(receiver);
}
}
BroadcastReceiver: 包com.comunicacio;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.TelephonyManager;
import android.util.Log;
public class DetectarCridada extends BroadcastReceiver {
public static final String CUSTOM_INTENT = "com.comunicacio.FINALITZAR";
@Override
public void onReceive(Context context, Intent intent) {
Bundle bundle = intent.getExtras();
if (bundle == null)
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("BYE", "UUUUUUUUUUUUUUUUL");
// if (es_acceptat(phonenumber)) {
Intent i = new Intent();
i.setAction(CUSTOM_INTENT);
context.sendBroadcast(i);
// }
}
}
private boolean es_acceptat(String telefono) {
if (telefono.equals("123"))
return true;
return false;
}
}
并且清单:
<uses-sdk android:minSdkVersion="10" />
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name" >

android:label="@string/app_name"

服务Sercivio.java: 包com.comunicacio;
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.os.IBinder;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;
import android.widget.Toast;
public class Servicio extends Service {
private static final String TAG = "MyService";
boolean hem_cridat = false;
int telefono = 123;
@Override
public IBinder onBind(Intent intent) {
return null;
}
@Override
public void onCreate() {
Toast.makeText(this, "My Service Created", Toast.LENGTH_LONG).show();
Log.d(TAG, "onCreate");
EndCallListener callListener = new EndCallListener();
TelephonyManager mTM = (TelephonyManager) this
.getSystemService(Context.TELEPHONY_SERVICE);
mTM.listen(callListener, PhoneStateListener.LISTEN_CALL_STATE);
}
@Override
public void onDestroy() {
Toast.makeText(this, "My Service Stopped", Toast.LENGTH_LONG).show();
}
@Override
public void onStart(Intent intent, int startid) {
Toast.makeText(this, "My Service Started", Toast.LENGTH_LONG).show();
call();
}
private class EndCallListener extends PhoneStateListener {
private static final String LOG_TAG = "Comunicacio:";
@Override
public void onCallStateChanged(int state, String incomingNumber) {
switch (state) {
case TelephonyManager.CALL_STATE_RINGING:
Log.i(LOG_TAG, "RINGING, number: " + incomingNumber);
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
Log.i(LOG_TAG, "OFFHOOK");
hem_cridat = true;
break;
case TelephonyManager.CALL_STATE_IDLE:
Log.i(LOG_TAG, "IDLE");
if (hem_cridat) {
hem_cridat = false;
try {
Log.i(LOG_TAG, "Cridant!");
call();
} catch (Exception e) {
e.printStackTrace();
}
}
break;
}
}
}
private void call() {
/* THE PROBLEM IS THERE !!! If I don't do that, it works! */
/* Intent i = new Intent(getBaseContext(), Call.class);
i.putExtra("NUMERO", telefono);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
getApplication().startActivity(i);
++telefono; */
}
}
最后是Call.java: 包com.comunicacio;
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
public class Call extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Bundle b = getIntent().getExtras();
Intent i = new Intent(Intent.ACTION_CALL, Uri.parse("tel:"
+ b.getInt("NUMERO")));
startActivity(i);
}
}
非常感谢你!

如果您想完成广播接收器的活动和活动,请在您的活动中创建另一个侦听特定意图的广播接收器。然后在您的第一个广播接收器中,当您想要杀死该活动时,广播您的活动中的接收者正在侦听的Intent。然后该接收器将被激活并且可以完成所有活动。
这是一些伪代码:
public class YourActivity extends Activity{
private class CloseLisntener extends BroadcastReceiver{
onReceive(Contetxt context, Intent intent){
YourActivity.this.finish();
}
}
private CloseListener closeListener;
protected void onCreate(Intent icicle){
closeListener = new CloseListener();
// other on create stuff
}
protected void onResume(){
registerReceiver(closeListener, /* Your intent filter goes here */);
}
protected void onPause(){
unregisterReceiver(closeListener);
}
}

问题出现了:
@Override
protected void onPause() {
super.onPause();
unregisterReceiver(receiver);
}
它停止了接收器,因此我将其更改为:
@Override
protected void onDestroy() {
super.onDestroy();
unregisterReceiver(receiver);
}
