从Dialog中删除边框,填充

Question

我有一个主题为Theme.Transparent的活动,它是:

<style name="Theme.Transparent" parent="android:Theme.Dialog">
    <item name="android:windowIsTranslucent">true</item>
    <item name="android:windowNoTitle">false</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:backgroundDimEnabled">false</item>
    <item name="android:gravity">top</item>
</style>

我正试图摆脱它周围的边框和填充..我想填补屏幕的水平.没有灰色边框.请帮忙 :)

Answer 1

请务必创建引用自定义主题的Dialog:

Dialog dialog = new Dialog(this, R.style.MyDialogTheme);

您的自定义主题需要填满屏幕并禁用几个Android框架默认值:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="MyDialogTheme" parent="android:Theme.Dialog">
        <!-- Fill the screen -->
        <item name="android:layout_width">fill_parent</item>
        <item name="android:layout_height">fill_parent</item>

        <!-- No backgrounds, titles or window float -->
        <item name="android:windowBackground">@null</item>
        <item name="android:windowNoTitle">true</item>
        <item name="android:windowIsFloating">false</item>      

        <!-- Just to prove it's working -->
        <item name="android:background">#ff0000</item>
    </style>

</resources>

与上面相同但是在代码中而不是在xml中为我工作.

    getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

Answer 3

设置宽度和高度以匹配父容器.

    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    WindowManager.LayoutParams wmlp = dialog.getWindow()
            .getAttributes();
    wmlp.width = android.view.WindowManager.LayoutParams.MATCH_PARENT;
    wmlp.height = android.view.WindowManager.LayoutParams.WRAP_CONTENT;
