Question

我正在创建拨号器，我想在点击按钮时断开呼叫，我正在尝试

public class OutgoingCallListener extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {     
            setResultData(null);
    }

}

这里我在按钮onclick功能中调用

try{
        OutgoingCallListener out = new  OutgoingCallListener();
        Intent intent = new Intent();
        out.onReceive(this, intent);    
    }catch(Exception e){
        Log.i("ii", "exception in end call", e);
    }

此处完成日志跟踪

exception in end call

Answer 1

为什么要调用onReceive方法？

当触发该事件时，会自动调用 BroadcastReceiver的onRecive（）方法（如果你注册的话是OutgoingCallListener）

java.lang.IllegalStateException：结果未挂起时调用
