PopupWindow 简单封装

public abstract class CommonPopWindow extends PopupWindow implements OnClickListener, PopupWindow.OnDismissListener {
    private int layout;
    private Context context;
    private View contentView;
    private View rotateView;
}

public CommonPopWindow(Context context, int layout, int width, int height) {
    this.context = context;
    this.layout = layout;
    this.setWidth(width);
    this.setHeight(height);
    init();
}

public CommonPopWindow(Context context, int layout) {
    this.context = context;
    this.layout = layout;
    this.setWidth(ViewGroup.LayoutParams.MATCH_PARENT);
    this.setHeight(ViewGroup.LayoutParams.MATCH_PARENT);
    init();
}

 private void init() {
        this.setFocusable(true);
// 设置PopupWindow的背景
        this.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
// 设置PopupWindow是否能响应外部点击事件
        this.setOutsideTouchable(true);
// 设置PopupWindow是否能响应点击事件
        this.setTouchable(true);
// 每个方法的作用都写在注解里了，相信大家都能看懂。不过这里要注意这两行：
// window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
// window.setOutsideTouchable(true);
// 只有同时设置PopupWindow的背景和可以响应外部点击事件，它才能“真正”响应外部点击事件。也就是说，当你点击PopupWindow的外部或者按下“Back”键时，PopupWindow才会消失。
