Android 设置对话框全屏

1、在styles.xml中添加一个style：

　　

 <style name="Dialog_Fullscreen">
    <item name="android:windowFullscreen">true</item>
    <item name="android:windowNoTitle">true</item>
</style>

2、在代码中设置dialog的theme:

Dialog dialog=new Dialog(getApplicationContext(),R.style.Dialog_FullScreen);
dialog.setContentView(R.layout.call_phone_layout);
//这句话与本章无关，用于在没有window的context上
dialog.getWindow().setType(WindowManager.LayoutParams.TYPE_SYSTEM_ALERT);
dialog.show();
