弹出窗口中的片段展示一些东西 [英] Pop up window to display some stuff in a fragment

问题描述

我试图使像一个弹出窗口，在片段的视图点击时会出现。我希望这个弹出窗口或什么的，不使该片段黑暗，就像一个对话片段一样。 而且我也不想被定位在弹出的观点被点击的地方。 将是一件好事，如果它有自己的活动和布局，所以我可以做它的一些自定义更改。 你能普莱舍给我一些示例code？

I am trying to make something like a pop-up window, that would appear when clicked on a view in a fragment. I want this pop-up window or whatever, to not make the fragment dark, like a Dialog Fragment does. And I also want the pop up to be positioned where the view is clicked. Would be good if it has its own activity and layout so I can do some custom changes in it. Can you plese show me some sample code?

推荐答案

以下应该正常工作，根据您的具体要求。从调用此方法在的onClick（视图v） OnClickListener 分配给视图：

The following should work perfect in accordance with your specification. Call this method from inside onClick(View v) of OnClickListener assigned to the View:

public void showPopup(View anchorView) {

    View popupView = getLayoutInflater().inflate(R.layout.popup_layout, null);

    PopupWindow popupWindow = new PopupWindow(popupView, 
                           LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

    // Example: If you have a TextView inside `popup_layout.xml`    
    TextView tv = (TextView) popupView.findViewById(R.id.tv);

    tv.setText(....);

    // Initialize more widgets from `popup_layout.xml`
    ....
    ....

    // If the PopupWindow should be focusable
    popupWindow.setFocusable(true);

    // If you need the PopupWindow to dismiss when when touched outside 
    popupWindow.setBackgroundDrawable(new ColorDrawable());

    int location[] = new int[2];

    // Get the View's(the one that was clicked in the Fragment) location
    anchorView.getLocationOnScreen(location);

    // Using location, the PopupWindow will be displayed right under anchorView
    popupWindow.showAtLocation(anchorView, Gravity.NO_GRAVITY, 
                                     location[0], location[1] + anchorView.getHeight());

}

的意见应该解释不够好。 anchorView 是 v 从的onClick（视图v）。
