我想收到短信并显示Dialog。 我怎么能这样做？
SmsReceiver：
public class SMSReceiver extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent)
{
//---get the SMS message passed in---
Bundle bundle = intent.getExtras();
SmsMessage[] msgs = null;
String str = "";
String num = "";
if (bundle != null)
{
//---retrieve the SMS message received---
Object[] pdus = (Object[]) bundle.get("pdus");
msgs = new SmsMessage[pdus.length];
for (int i=0; i<msgs.length; i++){
msgs[i] = SmsMessage.createFromPdu((byte[])pdus[i]);
if (i==0) {
//---get the sender address/phone number---
num += msgs[i].getOriginatingAddress();
}
//---get the message body---
str += msgs[i].getMessageBody().toString();
}
//---display the new SMS message---
if (num.equals("+XXXXXXXXX")){
Toast.makeText(context, str, Toast.LENGTH_SHORT).show();
//What to do here?
}
//---prevent this SMS message from being broadcasted---
abortBroadcast();
Log.d("SMSReceiver", str);
}
}
}
我的主要：
public class MainActivity extends FragmentActivity implements YesNoDialogListener {
GoogleMap googleMap;
Marker marker = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Getting Google Play availability status
int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getBaseContext());
// Showing status
if(status!=ConnectionResult.SUCCESS){ // Google Play Services are not available
int requestCode = 10;
Dialog dialog = GooglePlayServicesUtil.getErrorDialog(status, this, requestCode);
dialog.show();
}
else { // Google Play Services are available
// Getting reference to the SupportMapFragment of activity_main.xml
SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
// Getting GoogleMap object from the fragment
googleMap = fm.getMap();
// get my actual position and display a blue dot
googleMap.setMyLocationEnabled(true);
Location myLocation = googleMap.getMyLocation();
if( myLocation != null ){
Toast.makeText(this, "Latitude: " + myLocation.getLatitude() + "\nLongitude: " + myLocation.getLongitude(), Toast.LENGTH_SHORT).show();
}
if( myLocation == null ){
Toast.makeText(this, "Chujnia", Toast.LENGTH_SHORT).show();
}
}
}
//==Dialog yes/no
public void btnShowYesNoDialog(View view) {
showYesNoDialog();
}
public void showYesNoDialog() {
FragmentManager fragmentManager = getSupportFragmentManager();
YesNoDialogFragment yesnoDialog = new YesNoDialogFragment();
yesnoDialog.setCancelable(false);
yesnoDialog.setDialogTitle("New accident");
yesnoDialog.show(fragmentManager, "yes/no dialog");
}
@Override
public void onFinishYesNoDialog(boolean state) {
Toast.makeText(this, "Returned from dialog: " + state,
Toast.LENGTH_SHORT).show();
SmsManager sms = SmsManager.getDefault();
if (state == true){
sms.sendTextMessage("+XXXXXX", null, "OK", null, null);
}
else{
sms.sendTextMessage("+XXXXXXX", null, "No", null, null);
}
}
}
如何从SmsReceive执行btnShowYesNoDialog？ 现在它只有当我按下连接到btnShowYesNoDialog的按钮时才有效吗？

您可以将SMSReceiver放入MainActivity：
public class MainActivity extends FragmentActivity implements YesNoDialogListener {
private BroadcastReceiver SMSReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
//TODO
}
};
}
请记住注册广播接收器

抱歉。我没有仔细阅读你的代码。我认为你需要android application。
public class MyApplication extends Application{
private static MyApplication instance;
public static MyApplication getInstance(){
return instance;
}
@Override
public void onCreate() {
super.onCreate();
instance = this;
}
}
androidmanifest：
<application
android:name="xx.xx.MyApplication">
然后你可以在onReceive方法中显示Toast或对话框：
Toast.makeText(MyApplication.getInstance(), "ok", Toast.LENGTH_LONG).show();

如果您需要在应用程序打开期间（而不是服务）接收短信，您可以将Receiver置于主要活动中，如hewwcn answer中所述。
例如：
public class MainActivity extends Activity {
/*
* Variables for BroadcastReceiver
*/
boolean isRegistered = false; // check if BroadcastReceiver registered
private IntentFilter filterSmsReceived = new IntentFilter(
"android.provider.Telephony.SMS_RECEIVED");
/**
* Create BroadcastReceiver
*/
private BroadcastReceiver smsReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(
"android.provider.Telephony.SMS_RECEIVED")) {
/* get the SMS message passed in */
Bundle bundle = intent.getExtras();
SmsMessage[] msgs = null;
String msgFrom = null;
String msgBody = null;
if (bundle != null) {
/* retrieve the SMS message received */
try {
Object[] pdus = (Object[]) bundle.get("pdus");
msgs = new SmsMessage[pdus.length];
for (int i = 0; i < msgs.length; i++) {
msgs[i] = SmsMessage
.createFromPdu((byte[]) pdus[i]);
msgFrom = msgs[i].getOriginatingAddress();
msgBody = msgs[i].getMessageBody();
}
/*
* TODO Show dialog
*/
} catch (Exception e) {
// Log.d("Exception caught",e.getMessage());
}
}
}
}
};
/**
* Button - register BroadcastReceiver when clicked (or put it to onCreate)
*/
public void onButtonClicked(View v) {
this.registerReceiver(smsReceiver, filterSmsReceived);
isRegistered = true;
}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
protected void onPause() {
/*
* Unregister BroadcastReceiver
*/
if (isRegistered) {
this.unregisterReceiver(smsReceiver);
isRegistered = false;
}
super.onPause();
}
@Override
protected void onDestroy() {
/*
* Unregister BroadcastReceiver
*/
if (isRegistered) {
this.unregisterReceiver(smsReceiver);
isRegistered = false;
}
super.onDestroy();
}
}
