我怎样才能得到对话的结果 才能继续使用机器人
原标题:How can I get the result of a dialog before continuing in android

使用我活动的“Create ” 方法, 我用我制作的方法叫做“creatLocProvider () ” 。 它应该将一个地点提供者还给我。 我用这个方法显示一个警告对话框, 这是我的代码:

private void getLocProvider(){
    ArrayList<String> providers = new ArrayList<String>();

    List<String> list = locManager.getProviders(true);
    for(int i=0; i<list.size(); i++){
        if(list.get(i).equalsIgnoreCase("gps")){
            providers.add("GPS");
        }
        else if(list.get(i).equalsIgnoreCase("network")){
            providers.add("Network");
        }
    }

    providers.add("Manual");

    final CharSequence[] items = providers.toArray(new CharSequence[providers.size()-1]);


    AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(this);
    dialogBuilder.setTitle("Choose a way of finding your location:");
    dialogBuilder.setItems(items, new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int item) {
           //This is where I m stuck
        }
    });
    AlertDialog alert = dialogBuilder.create();
    alert.show();}

使用倾听器不会让我简单地通过这个方法返回结果, 所以有人知道我如何解决这个问题吗? 在谷歌搜索中,人们建议做另一个功能,在对话完成后被解雇,但是我怎样才能把结果还给我在Create方法上的工作呢?

Thanks, Zach

问题回答

通常您会将 UI 的创建和应用程序状态分开。 我建议为您创建一个 UI 的“ 无效” 状态, 然后在您对话框中点击用户后响应状态变化 。 这个模式在 C# 中很常见, 但在 Android 中并不常见 。 另外, 如果能够完成 < code > onCreate () , 在 UI 发布之前必须返回 。
