添加输入类型时 EditText 崩溃

在我的 Android 应用程序中，我有一个对话框，用户在其中将信息输入到 EditText 并保存数据。到目前为止，一切工作正常，直到我将 inputType 添加到 EditTexts 中。我似乎找不到这个问题的解决方案，我对 android 编程和一般编程相当陌生，所以这可能是一个愚蠢的错误，但我无法弄清楚。这里是一些代码：

private Dialog dialog() {
    Dialog diUnit = new Dialog(Overzicht.this);
    diUnit.setContentView(R.layout.unitdialog);
    EditText etKM = (EditText) diUnit.findViewById(R.id.etKM);
    etKM.setInputType(InputType.TYPE_CLASS_NUMBER);
    diUnit.setTitle("Add unit");
    diUnit.setCancelable(false);
    diUnit.getWindow().getAttributes().width = LayoutParams.FILL_PARENT;
    bUnitDialogSave = (Button) diUnit.findViewById(R.id.bUnitDialogVoegToe);
    bUnitDialogCancel = (Button) diUnit.findViewById(R.id.bUnitDialogCancel);
    bUnitDialogCancel.setOnClickListener(this);
    bUnitDialogAdd.setOnClickListener(this);
    return diUnit;
}

和 logcat ：

我知道它没有存储 EditText尚未输入，但一旦我添加 setInputType 行，问题就开始了。

In my android application I have a dialog box in which the user inputs info into an EditText and saves the data. Everything so far worked fine until I added an inputType to the EditTexts. I can't seem to find the solution to this problem, I'm rather new to android programming and programming in general so it might be a dumb mistake but I can't figure it out. Here some of the code:

private Dialog dialog() {
    Dialog diUnit = new Dialog(Overzicht.this);
    diUnit.setContentView(R.layout.unitdialog);
    EditText etKM = (EditText) diUnit.findViewById(R.id.etKM);
    etKM.setInputType(InputType.TYPE_CLASS_NUMBER);
    diUnit.setTitle("Add unit");
    diUnit.setCancelable(false);
    diUnit.getWindow().getAttributes().width = LayoutParams.FILL_PARENT;
    bUnitDialogSave = (Button) diUnit.findViewById(R.id.bUnitDialogVoegToe);
    bUnitDialogCancel = (Button) diUnit.findViewById(R.id.bUnitDialogCancel);
    bUnitDialogCancel.setOnClickListener(this);
    bUnitDialogAdd.setOnClickListener(this);
    return diUnit;
}

And the logcat :

I know it's not storing the EditText input yet but the problem starts as soon as I add the setInputType line.

尝试将布局 R.layout.unitdialog 膨胀为 View（使用 LayoutInflater），然后搜索该 EditText 在膨胀的 View 中：

private Dialog dialog() {
    Dialog diUnit = new Dialog(Overzicht.this);
    LayoutInflater inflater = (LayoutInflater) getLayoutInflater();
    View content = inflater.inflate(R.layout.unitdialog, null);
    diUnit.setContentView(content);
    EditText etKM = (EditText) content.findViewById(R.id.etKM);
    etKM.setInputType(InputType.TYPE_CLASS_NUMBER);
    diUnit.setTitle("Add unit");
    diUnit.setCancelable(false);
    diUnit.getWindow().getAttributes().width = LayoutParams.FILL_PARENT;
    bUnitDialogSave = (Button) diUnit.findViewById(R.id.bUnitDialogVoegToe);
    bUnitDialogCancel = (Button) diUnit.findViewById(R.id.bUnitDialogCancel);
    bUnitDialogCancel.setOnClickListener(this);
    bUnitDialogAdd.setOnClickListener(this);
    return diUnit;

Try to inflate the layout R.layout.unitdialog into a View(with the LayoutInflater) and then search for that EditText in the inflated View:

private Dialog dialog() {
    Dialog diUnit = new Dialog(Overzicht.this);
    LayoutInflater inflater = (LayoutInflater) getLayoutInflater();
    View content = inflater.inflate(R.layout.unitdialog, null);
    diUnit.setContentView(content);
    EditText etKM = (EditText) content.findViewById(R.id.etKM);
    etKM.setInputType(InputType.TYPE_CLASS_NUMBER);
    diUnit.setTitle("Add unit");
    diUnit.setCancelable(false);
    diUnit.getWindow().getAttributes().width = LayoutParams.FILL_PARENT;
    bUnitDialogSave = (Button) diUnit.findViewById(R.id.bUnitDialogVoegToe);
    bUnitDialogCancel = (Button) diUnit.findViewById(R.id.bUnitDialogCancel);
    bUnitDialogCancel.setOnClickListener(this);
    bUnitDialogAdd.setOnClickListener(this);
    return diUnit;
