将焦点添加到微调器 [英] Adding Focus to a spinner

问题描述

在这里，我有一个微调框和在微调框下方的一些文本字段.当文本字段之一具有焦点时，我从微调器中选择一个项目，然后看到焦点仍在该文本字段上，现在我想做的是，在所选微调器项目上，我想将焦点从该文本字段更改为微调器. 有什么办法可以将焦点设置到微调器上吗?

Here i have a spinner and some text fields below the spinner. when one of the text field has focus, i select an item from spinner and i see the focus is still on that text field, Now what i want to do is, on spinner item selected i want to change focus from that text field to the spinner. Is there any way to set focus to spinner?like,

    @Override
    public void onItemSelected(AdapterView<?> parent, View view,
            int position, long id) {
        //set focus to the spinner 
            }
        }

我遇到了类似的问题，并找到了答案的一部分

I had a similar problem and found part of the answer here.

但是，我还必须从代码而不是XML文件中设置focusable(true)和focusableInTouchMode(true).在代码中设置可聚焦属性之前，我无法使其正常工作.这是我的项目中的一个示例:

However, I also had to set focusable(true) and focusableInTouchMode(true) from my code and not the XML file. I couldn't get it to work until I set the focusable properties in the code. Here is a sample from my project:

spinUoM.setFocusable(true);
spinUoM.setFocusableInTouchMode(true);

spinUoM.setOnFocusChangeListener(new OnFocusChangeListener() {

        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if(hasFocus)
                DialogDefineRecipeActivity.this.spinUoM.performClick();
        }

    });
