Android(安卓)Dialog 全屏

一、在style中定义样式：

<?xml version="1.0" encoding="utf-8"?><resources>    <style name="Transparent">     <item name="android:windowBackground">@color/transparent_background</item>     <item name="android:windowNoTitle">true</item>     <item name="android:windowFullscreen">true</item>    <item name="android:windowIsTranslucent">true</item>       <item name="android:windowAnimationStyle">@+android:style/Animation.Translucent</item>   </style></resources>

其中transparent_background为颜色值：#50000000，透明度为50

二、代码中定义Dialog时添加样式：

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

全屏显示Dialog的设置

下面是Dialog的style:

<!-- 全屏dialog样式 左右插入 -->    <style name="mydialog" parent="@android:style/Theme.Dialog">        <item name="android:windowFrame">@null</item>        <item name="android:windowIsFloating">true</item>        <item name="android:windowIsTranslucent">true</item>        <item name="android:windowNoTitle">true</item>        <item name="android:backgroundDimEnabled">false</item>        <item name="android:windowBackground">#FFFFFF</item>    </style>

下面是创建Dialog的代码：

Dialog dialog = new Dialog(Activity.this, R.style.mydialog); dialog.setContentView(R.layout.layout); LayoutParams lay = dialog.getWindow().getAttributes(); setParams(lay); dialog.show();

private void setParams(LayoutParams lay) {  DisplayMetrics dm = new DisplayMetrics();  getWindowManager().getDefaultDisplay().getMetrics(dm);  Rect rect = new Rect();  View view = getWindow().getDecorView();  view.getWindowVisibleDisplayFrame(rect);  lay.height = dm.heightPixels - rect.top;  lay.width = dm.widthPixels; }
