定制的Andr​​oid微调 [英] Custom Android Spinner

问题描述

我寻找到创建自定义的项目选择又名微调我的应用程序。我想是这样你可以在应用程序松弛看到当你点击你所在的房间。

I'm looking into creating a custom project selector aka spinner for my App. I want something like what you can see in the Slack app when you click on the room you're in.

我觉得这是一个很好的老对话模式微调，但我不知道我是怎么做到以下几点：

I think this is a Spinner with a good old dialog mode but I'm not sure how I do the following:

1）删除背景色（在对话外）结果
2）在顶部锚的对话框而不是在屏幕的中心。

1) Remove the background tint (outside of the dialog)
2) Anchor the dialog at the top rather than the centre of the screen.

这是例子：

推荐答案

原来这就是我结束了，如果有人面临着类似的问题，这样做的：

So this is what I ended up doing if anyone faces a similar problem:

spinner.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if (event.getAction() != MotionEvent.ACTION_DOWN) {
                return true;
            }
            AlertDialog.Builder builder = new AlertDialog.Builder(context);
            builder.setAdapter(adapter, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                  //code goes here
                }
            });

            AlertDialog dialog = builder.create();
            dialog.setCanceledOnTouchOutside(true);
            WindowManager.LayoutParams wmlp = dialog.getWindow().getAttributes();

            wmlp.dimAmount=0.0f;
            wmlp.gravity = Gravity.TOP | Gravity.LEFT;
            wmlp.x = 100;   //x position
            wmlp.y = 100;   //y position

            dialog.getWindow().setAttributes(wmlp);
            dialog.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
            dialog.show();

            return true;
        }
    });

答案是基于<一个href=\"http://stackoverflow.com/questions/5469005/show-alertdialog-in-any-position-of-the-screen\">Show AlertDialog在屏幕中的任何位置，从而非常感谢原作者！

The answer is based on Show AlertDialog in any position of the screen so thanks a lot to the original author!
