彈窗展示

Activity.java中代碼

//PopupWindow彈窗
private void showNoneEffect() {
    LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View vPopupWindow = inflater.inflate(R.layout.popupwindow, null, false);//引入彈窗佈局
    popupWindow = new PopupWindow(vPopupWindow, ActionBar.LayoutParams.WRAP_CONTENT, ActionBar.LayoutParams.WRAP_CONTENT, true);
    //點擊外部彈出不消失
    popupWindow.setFocusable(false);
    popupWindow.setOutsideTouchable(false);
    //設置透明背景佈局
    setTransparentBg();

    popu_sj_vip = vPopupWindow.findViewById(R.id.popu_sj_vip);
    popu_sj_vip.setOnClickListener(this);

    //引入依附的佈局
    View parentView = LayoutInflater.from(this).inflate(R.layout.activity_setting, null);
    //相對於父控件的位置（例如正中央Gravity.CENTER，下方Gravity.BOTTOM等），可以設置偏移或無偏移
    popupWindow.showAtLocation(parentView, Gravity.CENTER, 0, 0);
}
private void setTransparentBg() {
    // 設置背景顏色變暗
    WindowManager.LayoutParams lp = getWindow().getAttributes();
    lp.alpha = 0.7f;//調節透明度
    getWindow().setAttributes(lp);
    //監聽彈窗
    popupWindow.setOnDismissListener(new PopupWindow.OnDismissListener() {
        @Override
        public void onDismiss() {
            //彈窗關閉  dismiss()時恢復原樣
            WindowManager.LayoutParams lp = getWindow().getAttributes();
            lp.alpha = 1f;
            getWindow().setAttributes(lp);
        }
    });
}
@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
    //攔截彈窗外部點擊事件
    if (popupWindow != null && popupWindow.isShowing()) {
        return false;
    }
    return super.dispatchTouchEvent(ev);
}
