Question

我的片段中有一个微调器。我希望当我点击微调器中的任何位置时，微调器视图应该接近并且微调器文本应该根据我的选择而改变。我的情况我必须在旋转器之外关闭它，它的文本保持不变。

public SmsBatchSpinnerListAdapter(Context context, BaseActivity activity, 
ArrayList<String> student, ArrayList<String> studentId, ArrayList<String> 
updatedSmsNumber, ArrayList<String> updatedUserId) 
 {
    super(context, R.layout.sms_batchname_spinner, stBatch);

    this.student = student;
    this.studentId = studentId;
    this.context = context;
    this.activity = activity;
    this.updatedUserId = updatedUserId;
    this.updatedSmsNumber = updatedSmsNumber;

 }

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    return getCustomView(position, convertView, parent);
}

@Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {

    return getCustomView(position, convertView, parent);
}

private View getCustomView(final int position, View convertView, final ViewGroup parent) {


    String name;
    inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    convertView = inflater.inflate(R.layout.sms_batchname_spinner, parent, false);
    final LinearLayout linearLayout = (LinearLayout) ((Activity) context).findViewById(R.id.hiddenlayout);
    studentBatch = (TextView) convertView.findViewById(R.id.text1);
    studentBatch.setTag(position);
    name = student.get(position);
    spinner = (Spinner) ((Activity)context).findViewById(R.id.spinner);
    studentBatch.setText(name);


    studentBatch.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                String idIndex = studentId.get(position);
                if(!idIndex.equals("0")){
                    linearLayout.setVisibility(view.VISIBLE);
                    getStudentName(studentId.get(position));



                }
                else{
                    //Toast.makeText(context,"Please select an item ",Toast.LENGTH_SHORT).show();
                }



            }
        });

    return convertView;
}

Answer 1

我确定，没有spinner存在关闭自己的方法和，

我认为studentBatch.setOnClickListener(...)是阻止微调器关闭的方法。相反，您可以将setOnItemSelectedListener(..)设置为微调器以在选择微调器项时获取事件，这也将关闭您的微调器（系统行为类型）。

此外， spinner.setSelection(int position)可以做到这一点。即

studentBatch.setOnClickListener(....) {
    spinner.setSelection(position);
}

Answer 2

使用setAdapter方法将arraylist绑定到微调器。您将在微调器中获取所选项目，对话将消失。

选择项目后关闭微调器视图
