使用活动为预警对话框膨胀customLayout时获取非法参数异常

Question

我正试图在我的警告对话框中给自定义布局充气，这给了我一个奇怪的例外。

活动中的代码

    setContentView(R.layout.blank);

    AlertDialog.Builder builder = new AlertDialog.Builder(this);

    View v = getLayoutInflater().inflate(R.layout.activity, null);
    builder.setView(v);
    builder.show();

更新

我发现我得到的context不是它的警报对象，所以它在这里崩溃

View rowView = LayoutInflater.from(context).inflate(R.layout.activity_calendar, null);

如何解决这个问题？

Answer 1

变化：

AlertDialog.Builder builder = new AlertDialog.Builder(this);

要：

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
