工具：BroadcastPhoneStates上下文=＆GT; ＆LT;的TextView
机器人：ID =@ + ID / textView1
机器人：layout_width =WRAP_CONTENT
机器人：layout_height =WRAP_CONTENT
机器人：layout_centerHorizontal =真
机器人：layout_centerVertical =真
机器人：文字=当事故发生时将通知您还好还好。 /＆GT; ＆LT;按钮

机器人：layout_below =@ + ID / textView1
机器人：layout_centerHorizontal =真
机器人：layout_marginTop =118dp
机器人：文字=接受/确认/＆GT;＆LT; / RelativeLayout的＆GT;
解决方案
findViewById（）是活动的方法。如果你的广播接收器您通过了活动 背景即可这样做：
Button1的=（按钮）（（活动）上下文）.findViewById（R.id.button1）;
When the button is clicked the audio that is playing has to stop and a message has to be sent. But its not doing either of them! The audio just plays does not stop! What did I do wrong in the code??
Here is my main activity
package com.androidexample.broadcastreceiver;
import java.io.IOException;
import com.wallpaper.rahuldravid.R;
import android.app.WallpaperManager;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.media.MediaPlayer;
import android.media.Ringtone;
import android.media.RingtoneManager;
import android.net.Uri;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.telephony.SmsMessage;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.Toast;
public class IncomingSms extends BroadcastReceiver {
private static final String LOGCAT = null;
MediaPlayer objPlayer;
Button Button1;
// Get the object of SmsManager
final SmsManager sms = SmsManager.getDefault();
public void onReceive(final Context context, Intent intent) {
// Retrieves a map of extended data from the intent.
final Bundle bundle = intent.getExtras();
try {
if (bundle != null) {
final Object[] pdusObj = (Object[]) bundle.get("pdus");
for (int i = 0; i < pdusObj.length; i++) {
SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
String phoneNumber = currentMessage.getDisplayOriginatingAddress();
String senderNum = phoneNumber;
String message = currentMessage.getDisplayMessageBody();
Log.i("SmsReceiver", "senderNum: "+ senderNum + "; message: " + message);
int duration = Toast.LENGTH_SHORT;
Toast toast = Toast.makeText(context, "senderNum: "+ senderNum + ", message: " + message, duration);
toast.show();
String serverNumber= "+919845147131";
if(senderNum.equals(serverNumber))
{
Toast toast1 = Toast.makeText(context,"alert message received!!!!",Toast.LENGTH_LONG);
toast1.show();
objPlayer = MediaPlayer.create(context,R.raw.hospital_alarm);
objPlayer.start();
Log.d(LOGCAT, "Media Player started!");
if(objPlayer.isLooping() != true){
Log.d(LOGCAT, "Problem in Playing Audio");
Button1 = (Button)findViewById(R.id.button1);
Button1.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
try {
objPlayer.stop();
objPlayer.release();
String phoneNumber = "919845147131";
String message = "Ambulance sent!";
SmsManager smsManager = SmsManager.getDefault();
smsManager.sendTextMessage(phoneNumber, null, message, null, null);
Toast toast2 = Toast.makeText(context,"acknowledgement sent!",Toast.LENGTH_LONG);
toast2.show();
}
finally {
}
}
});
}
}
} // end for loop
}
}// bundle is null
catch (Exception e) {
Log.e("SmsReceiver", "Exception smsReceiver" +e);
}
}
}
Here is my layout code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".BroadcastPhoneStates" >
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:text="When accident occurs you will be notified okay okay." />
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/textView1"
android:layout_centerHorizontal="true"
android:layout_marginTop="118dp"
android:text="Accept/Acknowledge" />
</RelativeLayout>
解决方案
findViewById() is a method of Activity. If to your BroadcastReceiver you passed the Activity context you can do:
Button1 = (Button) ((Activity)context).findViewById(R.id.button1);
