自定义AlertDialog创建时的AndroidRuntimeException（AlertDialog内的滚动视图）

我想要一个警报对话框，显示TextView和EditText的垂直线性布局，每对一行。对的数量每次都会变化，最多可以达到15-20个，因此将线性布局放在滚动视图中，但我得到以下例外

对不起，如果是错误的方式，只是谷歌和尝试。。在动态添加视图方面没有太多经验。。我确实得到了上面代码的滚动视图（我看到了滚动条），但是里面没有EditText和TextView

因为正如错误所述，您正在尝试创建

警报对话框

AlertDialog alertDialogGetMedicalReasons = builder.create();

在尝试设置

视图之前

 alertDialogGetMedicalReasons.setView(layout);

因此，您需要先调用

setView（）

，然后才能

create（）

将此行放入

requestWindowFeature(Window. FEATURE_CUSTOM_TITLE );

以前,

 AlertDialog.Builder builder = new AlertDialog.Builder(ChoosePresetsManipAbsenteesActivity.this);
            builder.setTitle("Enter Medical Leave Reasons");

---

在您的情况下，它可能会引发异常。。因为您正在尝试设置alertbuilderdialog的标题。。可能需要windowfeature来设置标题。。检查后让我知道..

这是否也会将我的线性布局封装在scrollview中？是的，可能是，但我不清楚您到底在做什么。您正在调用

setContentView（）

，然后调用

setView（）

。无论如何，您应该能够移动

AlertDialog alertDialogGetMedicalReasons=builder.create（）到正上方的
alertDialogGetMedicalReasons.show（）
我认为will workcontent视图具有scrollview xml文件引用，而我尝试使用SetView设置线性布局。您没有按照我所说的方式进行更改，请不要更改原始帖子，但您可以添加到其中。否则，它将变得混乱，对其他人来说毫无价值。将
builder.create（）
code移动到
.show（）
line.ohh ok.的正上方。。但是如何设置scrollview引用呢。。生成器没有setContentView（）？请在长注释中回答！：PI没有使用任何自定义标题。。那么是否需要该行呢？builder.setTitle（“输入病假原因”）；此行用于在aler builder中设置自定义标题，对吗？
