我需要在呼叫连接时启动计时器,但在我的情况下,它是在呼叫振铃时启动,我搜索了很多,但没有得到正确的解决方案。怀着希望,我正在重复这一点。至少我需要一个建议来实现这一目标。
我的代码:
public void onReceive(Context context, Intent intent) {
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
Log.d("Status", "Phone is Ringing");
} else if (state.equals(TelephonyManager.EXTRA_STATE_OFFHOOK)) {
Log.d("Status", "Phone is on call");
} else if (state.equals(TelephonyManager.EXTRA_STATE_IDLE)) {
// Call Dropped or rejected
System.exit(0);
Log.d("Status", "Phone is dropped");
}
}
答案 0 :(得分:0)
你可以尝试一下。 在BroadCastReceiver中
static boolean flag = false;
static long start_time, end_time;
onReceive函数将是这样的,
public void onReceive(Context arg0, Intent intent) {
String action = intent.getAction();
if (action.equalsIgnoreCase("android.intent.action.PHONE_STATE")) {
if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(
TelephonyManager.EXTRA_STATE_RINGING)) {
start_time = System.currentTimeMillis();
}
if (intent.getStringExtra(TelephonyManager.EXTRA_STATE).equals(
TelephonyManager.EXTRA_STATE_IDLE)) {
end_time = System.currentTimeMillis();
//Total time talked =
long total_time = end_time - start_time;
//Store total_time somewhere or pass it to an Activity using intent
}
}
此外,您还需要在Manifest中为此授予权限。
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
在你的Manifest中注册接收器,如下所示:
<receiver android:name=".CallDurationReceiver">
<intent-filter>
<action android:name="android.intent.action.PHONE_STATE" />
</intent-filter>
</receiver>
