Question

我在我的应用中遇到了一些关键问题。

拥有简单的列表视图，并在项目点击时以这种方式显示 AlertDialog.Builder ：

AlertDialog.Builder alert = new AlertDialog.Builder(getActivity());
    alert.setTitle("Credits finished , Upgrade Now.");
    alert.setMessage("Enter coupon code");
    final EditText input = new EditText(getActivity());
    alert.setView(input);
    .
    .
    .
    .

点击该项目后发生异常，而不是点击警告对话框中的edittext，android打开虚拟键盘，然后抛出此异常

        at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:595)
        at dalvik.system.NativeStart.main(Native Method)

在这里阅读了一些线程之后，我猜测它可能与视图的关注或者与InputMethod错误处理虚拟键盘相关，但没有找到可以解决它的结果。

很高兴知道以前是否有人遇到过这个问题，可以帮助我。

非常感谢您的帮助
