我;我以编程方式拒绝来电。 “呼叫拒绝”和“sendSMS”工作正常, 但我只想在手机处于充电模式时拒绝接听电话。
我正在尝试实现以下代码:
case TelephonyManager.CALL_STATE_RINGING:
if (isCharging())
{
reject();
sendSMS(incomingNumber);
}
break;
isCharging:
public boolean isCharging()
{
IntentFilter ifilter = new IntentFilter(Intent.ACTION_BATTERY_CHANGED);
Intent batteryStatus = contextMember.registerReceiver(null, ifilter);
int status = batteryStatus.getIntExtra(BatteryManager.EXTRA_STATUS, -1);
boolean bCharging = status == BatteryManager.BATTERY_STATUS_CHARGING ||
status == BatteryManager.BATTERY_STATUS_FULL;
return bCharging;
}
但该应用程序不断打击来电。
请帮我解决这个问题!

在Manifiest File中添加permisions
<receiver android:name=".PowerConnectionReceiver">
<intent-filter>
<action android:name="android.intent.action.ACTION_POWER_CONNECTED"/>
<action android:name="android.intent.action.ACTION_POWER_DISCONNECTED"/>
</intent-filter>
</receiver>
在你的班级中添加此代码,你可以设置一个变量标志isCharging并设置check。 BatteryManager以包含充电状态的粘性Intent广播所有电池和充电细节。
充电状态可以像插入设备一样轻松更改,因此监控充电状态以进行更改并相应地更改刷新率非常重要。
参考:// developer.android.com文档。
public class PowerConnectionReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
int status = intent.getIntExtra(BatteryManager.EXTRA_STATUS, -1);
boolean isCharging = status == BatteryManager.BATTERY_STATUS_CHARGING ||
status == BatteryManager.BATTERY_STATUS_FULL;
int chargePlug = intent.getIntExtra(BatteryManager.EXTRA_PLUGGED, -1);
boolean usbCharge = chargePlug == BatteryManager.BATTERY_PLUGGED_USB;
boolean acCharge = chargePlug == BatteryManager.BATTERY_PLUGGED_AC;
//remove some variables if you don't need it.
}
}

您的isCharging()
方法可能是从onReceive()
的{{1}}调用的。在这种情况下,即使使用BroadcastReceiver
第一个参数,也无法直接致电registerReceiver()
。
而不是:
null
尝试:
Intent batteryStatus = contextMember.registerReceiver(null, ifilter);

在您的活动中,创建一个新的BroadcastReceiver
实例或扩展它的类实例。同时创建您的IntentFilter
和过滤意图。然后在您的活动中,覆盖onReceive()
并添加您在活动收到相应意图时要执行的操作。
您可以在onResume()
中实例化接收器类,并在onPause()
中取消注册。
这样的事情:
public class YourAc extends Activity{
BroadcastReceiver br;
@Override
public void onResume(){
//instantiate your intent filter and other related stuff here
//register the receiver
}
@Override
public void onPause(){
//unregister your receiver
}
@Override
public void onReceive(){
//change the boolean isCharging to false
}
}
