更新Android的一个微调 [英] Update a spinner in Android

问题描述

在我的应用程序有1微调选项。在我6显示值（从值文件数组）。现在，当我点击了5个项目的微调值的所选项目将显示在屏幕上的活动微调。

当我在微调中选择第6项，我要开始新的活动。可能吗？我一定要由位置值做到这一点？

另外，在新的活动（后选择第6项），我在其中用户可以输入一个字符串应该替换微调的旧值5的EditText值。是否可以动态更新的微调？

我的飞旋code：

 微调S2 =（微调）findViewById（R.id.spinner1）;
ArrayAdapter＆LT;＆CharSequence的GT;适配器1 = ArrayAdapter.createFromResource（
  对此，R.array.group_array，android.R.layout.simple_spinner_item）;
adapter1.setDropDownViewResource（android.R.layout.simple_spinner_dropdown_item）;
s2.setAdapter（适配器1）;
 

解决方案

这是可能的。

的编码

  ArrayAdapter yearadp =新ArrayAdapter（这一点，android.R.layout.simple_spinner_item，yearlist）;
            yearadp.setDropDownViewResource（android.R.layout.simple_spinner_dropdown_item）;         year_spinner.setAdapter（yearadp）;
    索引= 0;     year_spinner.setOnItemSelectedListener（新AdapterView.OnItemSelectedListener（）{
            公共无效onItemSelected（适配器视图＆LT;＆GT;母公司，观景，INT POS，长I​​D）{
          spintext = parent.getItemAtPosition（POS）的ToString（）;                如果（spintext ==6）
                {
 意图=新意图（ListMonthActivity.this，NewChart.class）;
 startActivity（意向）;
 }
  }
    }
 

雅，我们可以用设置做

  mon_spinner.setSelection（iSelectedMonth）;
意图=新意图（ListMonthActivity.this，NewChart.class）;
 

您可能会或不提，而动作有一定的动作完成后，你可以传递到另一个活动。

In my application I have 1 spinner option. In that I am displaying 6 values (which is array from values file). Now in that when I click its 5 items of the spinner value the selected item will show in the spinner in the activity screen.

When I select 6th item in spinner I have to start a new activity. Is it possible? Do I have to do this by position value?

Also in the new activity (after selecting 6th item) I have 5 edittext values in which user can enter a string which should replace the old value in the spinner. Is it possible to dynamically update the spinner?

My spinner code:

Spinner s2=(Spinner)findViewById(R.id.spinner1);
ArrayAdapter<CharSequence> adapter1 = ArrayAdapter.createFromResource(
  this, R.array.group_array, android.R.layout.simple_spinner_item);
adapter1.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
s2.setAdapter(adapter1);     

解决方案

It's possible

Codings:

ArrayAdapter yearadp =  new ArrayAdapter(this,android.R.layout.simple_spinner_item,  yearlist);
            yearadp.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

         year_spinner.setAdapter(yearadp);
    index=0;

     year_spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            public void onItemSelected(AdapterView<?> parent, View view, int pos, long id) {
          spintext=parent.getItemAtPosition(pos).toString();

                if(spintext=="6")
                {
 intent        =    new Intent(ListMonthActivity.this,NewChart.class);
 startActivity(intent);
 }
  }
    }

Ya we can do with setting with

mon_spinner.setSelection(iSelectedMonth);
intent        =    new Intent(ListMonthActivity.this,NewChart.class);

You may or not mention while the action are certain action finished, and you can passed into another activity .
