java - 在 AlertDialog 中显示自定义 View

Question

我有一个扩展 LinearLayout 的类。它只包含两个 EditBox。单击某些按钮，我想在警报对话框中加载此类。当我点击按钮时，会显示警告对话框，但不会显示扩展 LinearLayout 的 View 类。代码如下。我被困在这个。我能得到一些解决方案吗？？

public class StudentDialog extends LinearLayout {
    Context context;
    LinearLayout layout;

    public StudentDialog(Context context) {
        super(context);
        this.context = context;
        createStudentDialog();
    }

    private void createStudentDialog() {

        layout = new LinearLayout(context);
        layout.setOrientation(LinearLayout.VERTICAL);
        layout.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
                LayoutParams.MATCH_PARENT));
        layout.setPadding(10, 10, 10, 10);
        layout.setId(200);

        EditText studentName = new EditText(context);
        studentName.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
                LayoutParams.WRAP_CONTENT));
        studentName
                .setTextAppearance(getContext(), TEXT_DIRECTION_FIRST_STRONG);

        EditText address = new EditText(context);
        address.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
                LayoutParams.WRAP_CONTENT));
        address.setTextAppearance(getContext(), TEXT_DIRECTION_FIRST_STRONG);

        layout.addView(studentName);
        layout.addView(address);

    }

}

//Now i am calling this on some button click listener as follows. The alert dialog is displayed but not the StudentDialog. 

StudentDialog dialog = new StudentDialog(this);



        AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
        alertDialogBuilder.setView(dialog);

        AlertDialog alertDialog = alertDialogBuilder.create();
        alertDialog.show();

Answer 1

如果你改变它应该工作

alertDialogBuilder.setView(dialog);

作为

alertDialogBuilder.setView(dialog.layout);
