Question

我正在设计药物提醒应用程序，我选择使用微调器，以便用户可以选择“每天一次”，“每天两次”或“每天三次”。

然后我想根据需要使用旋转器的答案来创建1,2或3个时间戳。

唯一的问题是我真的被困在如何做到这一点。

有人可以指出我正确的方向吗？

非常感谢

Answer 1

您可以在strings.xml中创建数组

function preFilterLookup() {
    var accountId = Xrm.Page.getAttribute("parentaccountid").getValue();

    Xrm.Page.getControl("my_lookup_field").addPreSearch(function () { 
        addFilter(accountId);
    });
}

Spinner arrayadapter适配器

<string-array name="time_arrays">
    <item>Once A Day</item>
    <item>Twice A Day</item>
    <item>Three Times A Day</item>
</string-array>

Answer 2

<强>初始化

   private Spinner spnSemester;
    ArrayAdapter<String> timeAdapter;
    List<String>courseList= new ArrayList<>();



  spnTime = (Spinner) findViewById(R.id.spnTime);
    courseList.add("Once A Day");
    courseList.add("Twice A Day");
    courseList.add("Thrice A Day");
    timeAdapter= new ArrayAdapter<String>(
    this,android.R.layout.simple_spinner_item,courseList);
    spnTime.setAdapter(timeAdapter);

timeAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

点击“侦听器”以获取值

spnTime.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                //Store selected value here

            }

            @Override
            public void onNothingSelected(AdapterView<?> parent) {

            }
        });

最初设计声明Spinner和TimePicker的xml布局，有关Spinner here

的详细信息

然后根据需要隐藏并显示timePicker。

public class MainActivity extends Activity implements  
AdapterView.OnItemSelectedListener {  

    String[] spinner_values = { "Once A Day", "Twice A Day", "Three Times A Day" };  

    @Override  
    protected void onCreate(Bundle savedInstanceState) { 
         //setup timepickers as required
        timepicker1=(TimePicker)findViewById(R.id.timePicker1);  
        timepicker2=(TimePicker)findViewById(R.id.timePicker2);  
        timepicker3=(TimePicker)findViewById(R.id.timePicker3);  
        //initially set visibility to GONE for all three timers
        //setup spinner
        Spinner spinner = (Spinner) findViewById(R.id.spinner1);  
        spinner.setOnItemSelectedListener(this); 
        ArrayAdapter adapter = new ArrayAdapter(this,android.R.layout.simple_spinner_item, spinner_values);  
        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);  
        spinner.setAdapter(adapter);  
    }  

    @Override  
    public void onItemSelected(AdapterView<?> arg0, View arg1, int position,long id) {  
        Switch(position){
            case 2 :
                //show timePicker3
            case 1:
                //show timepicker2
            case 0:
                //show timePicker1
                break;
            default
                //hide all timerPickers
                break;
        }  
    }
}

使用微调器创建一定数量的时间选择器
