推荐答案

T 他这个最好的解决办法，是处理广播消息，以确定手机状态。

The best solution for this, is handle broadCast message to identify phone state.

PhoneStateListener 此广播返回错误的结果，并多次致电状态的问题。

using PhoneStateListener for this broadcast returns wrong result and multiple state calling problem.

为什么我们在一个BroadcastReceiver声明监听器，而接收器接收状态改变状态？

Why we declare a listener on a broadcastReceiver while the Receiver receive states on states changing?

要prevent这个问题简单地定义这个类检测电话：

To prevent this issue simply detect call by defining this class:

public class PhoneState extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        state = intent.getStringExtra(TelephonyManager.EXTRA_STATE); 

        if(state.contains(TelephonyManager.EXTRA_STATE_RINGING))
        {
            // Phone is Ringing...  
        }   
        else if(state.contains(TelephonyManager.EXTRA_STATE_OFFHOOK)
        {
            // Call Answered
        }
        else if(state.contains(TelephonyManager.EXTRA_STATE_IDLE))
        {
            // Call is rejected or missed   
        }
    }
}

在这个清单添加到应用程序标记：

in your manifest add this to application tag:

<receiver android:name="receivers.PhoneState" >
        <intent-filter android:priority="2147483647">
            <action android:name="android.intent.action.PHONE_STATE" >
            </action>
        </intent-filter>
</receiver>

最后加入此权限：

and finally add this permission:

<uses-permission android:name="android.permission.READ_PHONE_STATE" />
