如何使用自定义布局创建对话框弹出窗口？

Posted 2023-02-16

我正在尝试创建具有自定义布局的对话框弹出窗口，但是我的自定义布局高度和弹出窗口高度不匹配。此外，弹出窗口还隐藏了一个按钮。我该怎么办，如何使弹出窗口的高度与自定义布局匹配？请帮我。我希望我的弹出窗口看起来像这样

但是看起来像这样

我的自定义布局

弹出对话框代码

popAddPost = new Dialog(this);
    popAddPost.setContentView(R.layout.pop_up_confirm_pickup);
    //popAddPost.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
    //popAddPost.getWindow().setLayout(Toolbar.LayoutParams.MATCH_PARENT,Toolbar.LayoutParams.WRAP_CONTENT);
    popAddPost.getWindow().getAttributes().gravity = Gravity.BOTTOM;

答案

这是我的做法：

private AlertDialog alertDialog;
alertDialog = buildDialog();
alertDialog.show();

private AlertDialog buildDialog()
        final AlertDialog dialogBuilder = new AlertDialog.Builder(context).create();
        LayoutInflater inflater = LayoutInflater.from(context);
        View dialogView = inflater.inflate(R.layout.dialog, null);

        dialogBuilder.setView(dialogView);

        dialogBuilder.setButton(DialogInterface.BUTTON_NEGATIVE, "CLOSE", new DialogInterface.OnClickListener() 
            @Override
            public void onClick(DialogInterface dialog, int which) 
                dialogBuilder.dismiss();
            
        );
        return dialogBuilder;
    

另一答案

在您的xml中，父布局在ConstraintLayout上使用RelativeLayout LayoutParams

删除android:layout_alignParentLeft="true"和android:layout_alignParentEnd="true"

ConstraintLayout也不支持layout_gravity，因此您也可以删除它。

<androidx.constraintlayout.widget.ConstraintLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/rectangle"
    android:layout_marginBottom="88dp">

代码

popAddPost = new Dialog(this);
popAddPost.setContentView(R.layout.pop_up_confirm_pickup);
Objects.requireNonNull(popAddPost.getWindow()).setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
popAddPost.show();
