我创建了一个"全屏" DialogFragment,我在其中添加了透明黑色背景。最终结果可以在下面的屏幕截图中看到:
这是我如何做到的:
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Dialog dialog = super.onCreateDialog(savedInstanceState);
dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);
return dialog;
}
@Override
public void onStart() {
super.onStart();
Dialog dialog = getDialog();
if (dialog != null) {
dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
// if >= LOLLIPOP, then I color the the statusbar
dialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
dialog.getWindow().setStatusBarColor(SOME_COLOR_HERE);
}
}
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setStyle(DialogFragment.STYLE_NO_TITLE, R.style.DialogFullScreen);
}
这是我在setStyle()上设置的主题:
<style name="DialogFullScreen">
<item name="android:windowIsFloating">false</item>
<item name="android:windowContentOverlay">@null</item>
</style>
这是我为片段充气的布局:

这些截图来自运行Android 5.1的Xperia Z3 这在许多设备上运行良好,甚至在一些低端的三星4.2设备上也经过测试。问题是它不适用于Nexus 4,也适用于Android 5.1。在Nexus 4上,似乎透明度不起作用,并且视图在后台被多次复制。这是一个截图:
这是Xperia Z3和Nexus 4之间的另一个比较:
Nexus 4上发生了什么? 任何帮助表示赞赏!

为对话框创建自定义布局,然后在onCreate或第一个对话框方法中使用下面的代码。
Dialog dialog = new Dialog(context);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.your_dialog_layout);
dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
它为我工作。我使用了一种方法来全屏创建对话框。

在onCreate()中使用以下代码为我工作了>
setStyle(STYLE_NO_FRAME, android.R.style.Theme_Holo_Light);`
在onStart()中使用以下内容
dialog.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
