文章目录引入效果图示例使用方法相关解释工具类封装最后奉上汪姑娘的Blog 引入 Android在需要类似于这样的弹窗会用到PopupWindo
Android在需要类似于这样的弹窗会用到PopupWindow，所以，我为此封装了PopupWindow工具类，请往下看！！！
分别有不同的效果：
在按钮上方显示
View inflate1 = LayoutInflater.from(MainActivity.this).inflate(R.layout.pop_item, null, false);
PopUtils popUtils1 = new PopUtils(v, inflate1);
popUtils1.showPop();
在按钮向上偏移100显示，向下改为负数即可
View inflate2 = LayoutInflater.from(MainActivity.this).inflate(R.layout.pop_item, null, false);
PopUtils popUtils2 = new PopUtils(v, inflate2);
popUtils2.showPopY(100);
在按钮向左偏移100显示，向右改为负数即可
View inflate3 = LayoutInflater.from(MainActivity.this).inflate(R.layout.pop_item, null, false);
PopUtils popUtils3 = new PopUtils(v, inflate3);
popUtils3.showPopX(100);
在按钮向上偏移100显示，向左偏移100显示，相反则改为负数即可
View inflate4 = LayoutInflater.from(MainActivity.this).inflate(R.layout.pop_item, null, false);
PopUtils popUtils4 = new PopUtils(v, inflate4);
popUtils4.showPopXY(100, 100);
//获取View，R.layout.xxx 是PopupWindow要展示的内容
View inflate = LayoutInflater.from(上下文Context).inflate(R.layout.xxx, null, false);
//在这里写PopupWindow中的控件相关事件
...
//实例化
//v：点击/长按事件传回来的View
//inflate：PopupWindow要展示的View
PopUtils popUtils = new PopUtils(v, inflate);
//显示PopupWindow
popUtils.showPop();
综合几点考虑而封装
定义PopupWindow窗口位置 根据View事件位置弹出
public class PopUtils {
private View v;
private PopupWindow popupWindow;
private int[] location;
private int popupWidth;
private int popupHeight;
PopUtils(View v, View inflate) {
this.v = v;
popupWindow = new PopupWindow(inflate, ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT, true);
popupWindow.setBackgroundDrawable(new BitmapDrawable());
inflate.measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);
popupWidth = inflate.getMeasuredWidth();
popupHeight = inflate.getMeasuredHeight();
location = new int[2];
v.getLocationOnScreen(location);
}
public void showPop() {
popupWindow.showAtLocation(v, Gravity.NO_GRAVITY, (location[0] + v.getWidth() / 2) - popupWidth / 2, location[1] - popupHeight);
}
public void showPopY(int offsetY) {
popupWindow.showAtLocation(v, Gravity.NO_GRAVITY, (location[0] + v.getWidth() / 2) - popupWidth / 2, location[1] - popupHeight - offsetY);
}
public void showPopX(int offsetX) {
popupWindow.showAtLocation(v, Gravity.NO_GRAVITY, (location[0] + v.getWidth() / 2) - popupWidth / 2 - offsetX, location[1] - popupHeight);
}
public void showPopXY(int offsetX, int offsetY) {
popupWindow.showAtLocation(v, Gravity.NO_GRAVITY, (location[0] + v.getWidth() / 2) - popupWidth / 2 - offsetX, location[1] - popupHeight - offsetY);
}
public void dismissPop() {
if (null != popupWindow) {
popupWindow.dismiss();
}
}
}
