砖垛之PopupWindow

一、PopupWindow弹出后，当里面有editext时，要弹出键盘，这时键盘会遮挡pop
解决；

popupWindow.setSoftInputMode(PopupWindow.INPUT_METHOD_NEEDED); 
popupWindow.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE); 

注意；这两个设置的顺序不能变，并且要在设置showAtLocation之前设置
二、封装

/*** description: pop工具类* autour: mo* date: 2017/7/28 0028 15:15*/
public abstract class UtilPop {public interface PopCallBack {void getData(PopupWindow window, String selectId, int position);}/*** @param context      上下文* @param layoutId     布局id* @param atLocationId 显示位置id* @param hight        高度状态 0 自适应 1 胀满* @param upOrDown     0从下往上弹，1 从上往下弹*/public UtilPop(Activity context, int layoutId, int atLocationId, int hight, int upOrDown) {View v = ((LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(layoutId, null);//填充视图PopupWindow window;if (hight == 0) {window = new CustomPopupWindow(v, WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);//创建window} else if (hight == 1) {window = new CustomPopupWindow(v, WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT);//创建window//遮住状态栏fitPopupWindowOverStatusBar(window, true);} else {window = new CustomPopupWindow(v, WindowManager.LayoutParams.MATCH_PARENT, hight);//创建window}window.setFocusable(true); // 设置popWindow弹出窗体可点击，这句话必须添加，并且是truewindow.setBackgroundDrawable(new ColorDrawable(0xb000000)); // 实例化一个ColorDrawable颜色为半透明if (upOrDown == 0) {//解决PopupWindow含有输入框时，点击输入框，软键盘可能会挡住PopupWindow 顺序不能变window.setSoftInputMode(PopupWindow.INPUT_METHOD_NEEDED);window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);window.setAnimationStyle(R.style.mypopwindow_anim_style); // 设置popWindow的显示和消失动画window.showAtLocation(context.findViewById(atLocationId), Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL, 0, 0); // 在底部显示} else if (upOrDown == 1) {window.setAnimationStyle(R.style.pop_top_anim_style); // 设置popWindow的显示和消失动画window.showAsDropDown(context.findViewById(atLocationId)); // 在底部显示}// 设置背景颜色变暗final Window bgWindow = context.getWindow();WindowManager.LayoutParams lp = bgWindow.getAttributes();
//        lp.alpha = 0.7f;lp.alpha = 0.95f;context.getWindow().setAttributes(lp);window.setOnDismissListener(new PopupWindow.OnDismissListener() {@Overridepublic void onDismiss() {WindowManager.LayoutParams lp = bgWindow.getAttributes();lp.alpha = 1f;bgWindow.setAttributes(lp);}});doWhat(v, window, bgWindow);}protected abstract void doWhat(View v, PopupWindow window, Window bgWindow);public static void fitPopupWindowOverStatusBar(PopupWindow mPopupWindow, boolean needFullScreen) {if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {try {Field mLayoutInScreen = PopupWindow.class.getDeclaredField("mLayoutInScreen");mLayoutInScreen.setAccessible(needFullScreen);mLayoutInScreen.set(mPopupWindow, needFullScreen);} catch (NoSuchFieldException e) {e.printStackTrace();} catch (IllegalAccessException e) {e.printStackTrace();}}}
}

三、自定义解决在7.0及其他版本中无法正常在设置的位置显示

public class CustomPopupWindow extends PopupWindow {public CustomPopupWindow(View contentView, int width, int height) {this(contentView, width, height, false);}public CustomPopupWindow(View contentView, int width, int height, boolean focusable) {super(contentView, width, height, focusable);}@Overridepublic void showAsDropDown(View anchor) {if (Build.VERSION.SDK_INT == 24) {Rect rect = new Rect();anchor.getGlobalVisibleRect(rect);int h = anchor.getResources().getDisplayMetrics().heightPixels - rect.bottom;setHeight(h);}super.showAsDropDown(anchor);}}
