我正在尝试接听来电广播，但它不起作用。
这是我的清单：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.test.bgPicture"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk android:minSdkVersion="9" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
<uses-feature
android:name="android.hardware.camera"
android:required="false" />
<uses-feature
android:name="android.hardware.camera.front"
android:required="false" />
<application
android:icon="@drawable/icon"
android:label="@string/app_name" >
<receiver android:name=".PhoneStateBroadcastReceiver" >
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
</receiver>
</application>
这是我的广播接收器
package com.test.bgPicture;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
public class PhoneStateBroadcastReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context context, Intent intent) {
TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
telephonyManager.listen(new CustomPhoneStateListener(context), PhoneStateListener.LISTEN_CALL_STATE);
}
}
还有听者..
package com.test.bgPicture;
import android.content.Context;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.widget.Toast;
public class CustomPhoneStateListener extends PhoneStateListener {
//private static final String TAG = "PhoneStateChanged";
Context context; //Context to make Toast if required
public CustomPhoneStateListener(Context context) {
super();
this.context = context;
}
@Override
public void onCallStateChanged(int state, String incomingNumber) {
super.onCallStateChanged(state, incomingNumber);
switch (state) {
case TelephonyManager.CALL_STATE_IDLE:
//when Idle i.e no call
Toast.makeText(context, "Phone state Idle", Toast.LENGTH_LONG).show();
break;
case TelephonyManager.CALL_STATE_OFFHOOK:
//when Off hook i.e in call
//Make intent and start your service here
Toast.makeText(context, "Phone state Off hook", Toast.LENGTH_LONG).show();
break;
case TelephonyManager.CALL_STATE_RINGING:
//when Ringing
Toast.makeText(context, "Phone state Ringing", Toast.LENGTH_LONG).show();
break;
default:
break;
}
}
}
但是没有显示敬酒，有什么想法吗？
编辑：我刚刚用另一部带有 android 2.3.6 的手机试了一下，它在那里工作，但在第一台设备（android 4.1）上它不起作用。为什么会这样？
