public void onActivityCreated(Bundle savedInstanceState)
{
Window window = getDialog().getWindow();
LayoutParams attributes = window.getAttributes();
//must setBackgroundDrawable(TRANSPARENT) in onActivityCreated()
window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
if (needFullScreen)
{
window.setLayout(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
}
}
其实Dialog, DialogFragment, Activity 能看到的界面,都是基于Window显示的; 也就是修改样式, 都是在修改window的样式; 所以,本质上方法都是一样的,唯一不同的就是获取window对象的方法不一样; Dialog 通过, getWindow() 获取; Activity 也是通过, getWindow() 获取; DialogFragment 则是getDialog().getWindow()获取; 有了window对象, 就可以开始本文了: 1:修改Dialog中window宽度和高度 //public static final int FILL_PARENT = -1; //public static final int MATCH_PARENT = -1; //public static final int WRAP_CONTENT = -2; dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));//注意此处 dialog.setContentView(textView, new ViewGroup.LayoutParams(-2, -2)); dialog.getWindow().setLayout(-1, -2);//setLayout必须 在 setContentView之后, 调用;并且 setBackgroundDrawable 必须设置 //这里的-1,-2可以设置为任意高度;123456712345672:修改DialogFragment中window宽度和高度 在DialogFragment的onCreateView()方法中 public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { final Window window = getDialog().getWindow(); View view = inflater.inflate(R.layout.dialog_fragment_layout, ((ViewGroup) window.findViewById(android.R.id.content)), false);//需要用android.R.id.content这个view window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));//注意此处 window.setLayout(-1, -2);//这2行,和上面的一样,注意顺序就行; return view; }123456712345673:附赠Activity中修改window的宽度和高度 在Activity的onAttachedToWindow方法中 @Override public void onAttachedToWindow() { Window window = getWindow(); WindowManager.LayoutParams attributes = getWindow().getAttributes(); attributes.width = 460; attributes.height = 700; window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));//注意此处 getWindow().setAttributes(attributes); super.onAttachedToWindow(); }1234567891012345678910Winodw的其实属性修改: mWindow = getDialog().getWindow(); //无标题 mWindow.requestFeature(Window.FEATURE_NO_TITLE);//必须放在setContextView之前调用 rootView = (ViewGroup) inflater.inflate(R.layout.rsen_base_dialog_fragment_layout, (ViewGroup) mWindow.findViewById(android.R.id.content)); //透明状态栏 mWindow.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); //退出,进入动画 mWindow.setWindowAnimations(getAnimStyles()); //清理背景变暗 mWindow.clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND); //点击window外的区域 是否消失 getDialog().setCanceledOnTouchOutside(canCanceledOnOutside()); //是否可以取消,会影响上面那条属性 setCancelable(canCancelable()); //window外可以点击,不拦截窗口外的事件 mWindow.addFlags(WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL); //设置背景颜色,只有设置了这个属性,宽度才能全屏MATCH_PARENT mWindow.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT)); WindowManager.LayoutParams mWindowAttributes = mWindow.getAttributes(); mWindowAttributes.width = getWindowWidth();//这个属性需要配合透明背景颜色,才会真正的 MATCH_PARENT mWindowAttributes.height = WindowManager.LayoutParams.WRAP_CONTENT; //gravity mWindowAttributes.gravity = getGravity(); mWindow.setAttributes(mWindowAttributes); //没啦,更多属性可以在API文档里面查看.12345678910111213141516171819202122232425261234567891011121314151617181920212223242526mLayoutParams.flags = WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN// 覆盖状态栏 | WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL//窗口外可以点击 | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE//不监听按键事件 // | WindowManager.LayoutParams.FLAG_LAYOUT_INSET_DECOR // | WindowManager.LayoutParams.FLAG_LAYOUT_IN_OVERSCAN | WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS//突破窗口限制 // | WindowManager.LayoutParams.FLAG_FULLSCREEN ;12345678 12345678
