Question

我在定义自己的警报式对话框时遇到了一些严重的问题，包括性感的颜色和徽标。这一切都很好，我几乎就在那里，只是一个小问题。

当有大量文字时，对话框会填满整个屏幕。查看正常的警报对话框，当消息很长时，滚动视图占用的最大宽度和高度都很好。

有人能告诉我如何使用此设置模拟传统警报对话框的尺寸吗？

从我看过的各种线程中，这是我的解决方案（对代码的长度道歉，我猜最重要的部分是xml中的scrollview）：

MyDialog.java

public class MyDialog extends Dialog {

    public MyDialog(Context context, int theme) {
        super(context, theme);
        // TODO Auto-generated constructor stub
    }

}

MainActivity

MyDialog dialog = new MyDialog(getActivity(), R.style.greenDialog);
dialog.setContentView(R.layout.dialog_about);
TextView titleTextView = (TextView) dialog.findViewById(R.id.alertTitle);
titleTextView.setText(title);

TextView text = (TextView) dialog.findViewById(R.id.message);
text.setText("Blah blah blah" +

</LinearLayout>

这非常接近android的alert_dialog.xml另外需要注意的是样式使用无标题功能，否则我会得到奇怪的空填充：

styles.xml

<style name="greenDialog" parent="android:Theme.Dialog">
    <item name="android:windowNoTitle">true</item>
    <item name="android:windowBackground">@color/green_shadow</item>
</style>

编辑：为了比较，这里是一个具有相同文本的正常警告对话框：

Answer 1

在dialog_about.xml中，将LinearLayout android:id="@+id/parentPanel"高度设置为所需大小而不是android:layout_height="wrap_content"，并在LinearLayout android:id="@+id/parentPanel"内使用scrollview，它将正常工作......

Android - 自定义对话框太大
