android - Android：Toast 类型中的方法 makeText(Context, CharSequence, int) 不适用于参数 (MyBroadCastReceiver, String, int)

Question

我无法弄清楚错误，请帮助这是代码。我不断收到“Toast 类型中的方法 makeText（Context，CharSequence，int）不适用于参数（MyBroadCastReceiver，String，int）”

    public class MyBroadCastReceiver extends BroadCastReceiver {

public void onReceive(Context context, Intent alarmIntent) {
    // TODO Auto-generated method stub

    Toast.makeText(MyBroadCastReceiver.this, "Alarm worked", Toast.LENGTH_LONG).show();
}

}

Answer 1

应该

Toast.makeText(context, "Alarm worked", Toast.LENGTH_LONG).show();

Answer 2

尝试 makeText(context, ...) 代替。

Answer 3

您必须让活动作为上下文传递。尝试

Toast.makeText(MyBroadCastReceiver.this.getActivity(),"报警工作", Toast.LENGTH_LONG).show();
