最近在写PopupWindow，一直在重复搬砖，而且代码繁复，实在做无用功，所以将PopupWindow进行封装。
代码采用Builder模式设计，只注重构建的属性，而不注重构建的过程。
代码已传至github，欢迎star--https://github.com/shuaijia/JsPopupWindow
贴出代码如下
/** * Describtion: 对popupWindow的封装 * Created by jia on 2017/7/10. * 人之所以能，是相信能 */ public class JsPopupWindow { private PopupWindow mPopupWindow; private View mContentView; private Context mContext; public JsPopupWindow(Builder builder) { mContext = builder.getContext(); // 创建view mContentView = LayoutInflater.from(mContext).inflate(builder.getContentViewId(), null); // 创建popupWindow mPopupWindow = new PopupWindow(mContentView, builder.getWidth(), builder.getHeight(), builder.isFouse()); mPopupWindow.setOutsideTouchable(builder.isOutSideCancle()); mPopupWindow.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT)); mPopupWindow.setAnimationStyle(builder.getAnimation()); } /** * 消失 */ public void dismiss() { if (mPopupWindow != null && mPopupWindow.isShowing()) { mPopupWindow.dismiss(); } } /** * 获取控件 * * @param itemId * @return */ public View getItemView(@NonNull int itemId) { if (mPopupWindow != null && mContentView != null) { return mContentView.findViewById(itemId); } return null; } /** * 在父布局特定位置显示 * * @param rootViewId * @param gravity * @param x * @param y * @return */ public JsPopupWindow showAtLocation(int rootViewId, int gravity, int x, int y) { if (mPopupWindow != null) { View rootView = LayoutInflater.from(mContext).inflate(rootViewId, null); mPopupWindow.showAtLocation(rootView, gravity, x, y); } return this; } public JsPopupWindow showAsLocation(int targetViewId, int gravity, int offx, int offy) { if (mPopupWindow != null) { View targetview = LayoutInflater.from(mContext).inflate(targetViewId, null); mPopupWindow.showAsDropDown(targetview, offx, offy, gravity); } return this; } public JsPopupWindow showAsLocation(View targetView, int gravity, int offx, int offy) { if (mPopupWindow != null) { mPopupWindow.showAsDropDown(targetView, offx, offy, gravity); } return this; } /** * 根据id设置焦点监听 * * @param viewid * @param listener */ public void setOnFocusListener(int viewid, View.OnFocusChangeListener listener) { View view = getItemView(viewid); view.setOnFocusChangeListener(listener); } /** * 在父布局特定位置显示 * * @param gravity * @param x * @param y * @return */ public JsPopupWindow showAtLocation(View rootView, int gravity, int x, int y) { if (mPopupWindow != null) { mPopupWindow.showAtLocation(rootView, gravity, x, y); } return this; } public static class Builder { private Context context; private int contentViewId; private int width; private int height; private boolean fouse; private boolean outSideCancle; private int animation; public Context getContext() { return context; } public Builder setContext(Context context) { this.context = context; return this; } public int getContentViewId() { return contentViewId; } public Builder setContentViewId(int contentViewId) { this.contentViewId = contentViewId; return this; } public int getWidth() { return width; } public Builder setWidth(int width) { this.width = width; return this; } public int getHeight() { return height; } public Builder setHeight(int height) { this.height = height; return this; } public boolean isFouse() { return fouse; } public Builder setFouse(boolean fouse) { this.fouse = fouse; return this; } public boolean isOutSideCancle() { return outSideCancle; } public Builder setOutSideCancle(boolean outSideCancle) { this.outSideCancle = outSideCancle; return this; } public int getAnimation() { return animation; } public Builder setAnimation(int animation) { this.animation = animation; return this; } /** * 构建 * * @return */ public JsPopupWindow build() { return new JsPopupWindow(this); } } }
