如何降低MaterialAlertDialog的消息高度

Question

我正在尝试使用MaterialAlertDialogBu​​ilder创建MaterialAlertDailog。我设法在styles.xml中控制对话框的大多数属性，但消息和“确定”按钮之间的空间除外。

我目前正在使用此依赖项：

implementation "com.google.android.material:material:1.1.0"

styles.xml

<resources>

    <!-- Base application theme. -->
    <style name="AppTheme" parent="@style/Theme.MaterialComponents.Light">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>


    <style name="MaterialDialogDark" parent="@style/ThemeOverlay.MaterialComponents.MaterialAlertDialog">
        <!-- Customize your theme here. -->
        <item name="colorSurface">@color/material_dialog_background_color_dark</item>
        <item name="buttonBarPositiveButtonStyle">@style/MaterialAlert.Button.Dark</item>
        <item name="buttonBarNegativeButtonStyle">@style/MaterialAlert.Button.Dark</item>

        <item name="android:textColor">@color/material_dialog_title_color_dark</item>
    </style>

</resources>

MainActivity.java

findViewById(R.id.testDialog).setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View v) {
                new MaterialAlertDialogBuilder(MainActivity.this ,R.style.MaterialDialogDark)
                        .setTitle(R.string.label_title)
                        .setMessage(R.string.label_not_enough_points)

                        .setPositiveButton(android.R.string.ok,(dialogInterface, i) -> {})
                        .show();
            }
        });

我意识到没有简单的解决方法（至少是通过styles.xml来解决的）。最后，我创建了一个自定义布局（仅具有textview），然后按预期的方式工作。

custom_text.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/message"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:textSize="18sp"
    android:textColor="@color/material_dialog_body_color"
    android:paddingTop="15dp"
    android:paddingBottom="15dp"
    android:paddingLeft="23dp"
    android:paddingRight="23dp"/>

      findViewById(R.id.testDialog).setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View v) {
                  AlertDialog dialog = new MaterialAlertDialogBuilder(MainActivity.this ,R.style.MaterialDialogDark)
                        .setTitle(R.string.label_title)
//                        .setMessage(R.string.label_mark_used_sure)
                        .setView(R.layout.material_text_alet_dialog)
                        .setPositiveButton(R.string.label_yes,(dialogInterface, i) -> {
                            Toast.makeText(MainActivity.this, "Positive", Toast.LENGTH_LONG).show();
                        })

                        .setNegativeButton(R.string.label_no,(dialogInterface, i) -> {
                            Toast.makeText(MainActivity.this, "Negative", Toast.LENGTH_LONG).show();
                        }).show();


                  TextView msgText = dialog.findViewById(R.id.message);
                  msgText.setText(getString(R.string.not_authorized));



            }
        });
