我使用androidandroid.app.Dialog
创建一个自定义对话框(用于按钮和背景)在我的对话框中我有TextView
一段ScrollView
时间我有一个简短的文本,这完美地显示了我想要的方式,但是如果文本很大,我的对话框会占据整个屏幕,我希望在对话框和屏幕边缘之间有一个最小边距。
我的问题是我希望对话框不要比需要的大,我不能为此设置固定大小?
Here is how this look today.....I what a margin like this
这GameDialog.java
public class GameDialog extends Dialog {
public GameDialog(Context ct, int titleID, int messageID) {
super(ct, R.style.dialog_style);
this.setContentView(R.layout.dialog_layout);
}
// This exist more code but this has noting with the layout to do,only set the text and show the button that exist since the XML file.
}
这R.style.dialog_style
<style name="dialog_style" parent="@android:style/Theme.Dialog">
<item name="android:windowBackground">?button_image</item>
<item name="android:windowNoTitle">true</item>
<item name="android:textColor">#FF000000</item>
<item name="android:textSize">20sp</item>
</style>
这R.layout.dialog_layout
