Question

我正在尝试在选择Spinner中的某个Item时显示EditText。到目前为止，我已经创建了微调器和EditText，但我真的不知道我的下一步是什么。我不想在EditText中显示选择，我只想显示EditText字段。

 @Override
public void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    final EditText editText = (EditText) findViewById(R.id.edit_text_box);
    editText.getText().toString();




}


public void addItemsOnSpinner()
{
    spinner1 = (Spinner) findViewById(R.id.spinner);
    ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource
    (this, R.array.spinner_item, android.R.layout.simple_spinner_item);
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner1.setAdapter (adapter);

}

public void onItemSelected(AdapterView<?> spinner1, View view,int pos, long id)
{

        editText.setText(spinner1.getSelectedItem());

}

这也是我在字符串数组中所拥有的内容+希望仅在选择item2时显示edittext框

<string-array name="spinner_item">
    <item>Item 1</item>
    <item value="Item2">Item 2</item>
    <item>Item 3</item>
    <item>Item 4</item>
</string-array>

Answer 1

您应该将editText的可见性设置为不可见或以XML格式显示，取决于更适合您的需求。那么您可以使用以下内容来显示它：

public void onItemSelected(AdapterView<?> spinner1, View view,int pos, long id)
{
 yourEditText.setVisibility(View.VISIBLE);
}

Answer 2

    spinner1.setOnItemSelectedListener(new OnItemSelectedListener() {

        public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {
            int x = spinner1.getSelectedItemPosition();
            valSel = items[x];
    }
String spinner1val = spin1.getText().toString();         //extract value of text from spinner

EditText text = (EditText) findViewById(R.id.EditText1);  //get id of EditText box
text.setText(spinner1val);

或者，如果要检查在Spinner中选择的项的值，则“valsel”包含该值。只是祝酒词。

Answer 3

您必须在edittext onItemSelected上设置文字。首先根据 MKJParekh 建议进行更改。

public void onItemSelected(AdapterView<?> spinner1, View view,int pos, long id)
{
   yourEditText.setText(spinner1.getSelectedItem())
}

Answer 4

从微调器中获取所选值

String anyvariable=String.valueOf(spin.getSelectedItem());

现在，您可以在编辑文本

中显示此字符串值

EditText text = (EditText) findViewById(R.id.your_text);
text.setText(anyvariable);

Answer 5

        @Override
        public void onItemSelected(AdapterView<?> month, View arg1,int arg2, long arg3) {
            // TODO Auto-generated method stub
            selectedMonth=  month.getItemAtPosition(arg2).toString();
            Log.d("Tag",""+selectedMonth);
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub
            //selected_item=    arg0.getChildAt(1).toString();

        }
        });

        selected_item contains the item ,so just set it to editView like
         editView.setText(selected_item)

Answer 6

EditText height1，weight1，height，weight; Spinner height_spinner， weight_spinner; String heightInputString，weightInputString;按键 calculatebmi;

@Override protected void onCreate（Bundle savedInstanceState）{ super.onCreate（savedInstanceState）; 的setContentView（R.layout.activity_bmi）;
```
// set your class members as they start out null.
// do this for all of them 
height1 = (EditText) findViewById(R.id.idofheight1inxml);
height_spinner = (Spinner) findViewById(R.id.idofheightspinnerinxml); 
....

    // Show the Up button in the action bar.
setupActionBar();
setupSpinners(); }
```
void setupSpinners（）{ height_spinner.setOnItemSelectedListener（new AdapterView.OnItemSelectedListener（）{ @覆盖 public void onItemSelected（AdapterView parent，View view，int position，long id）{ //I.E。如果在高度微调器CM中被选中，我想隐藏第二个高度的edittext字段。 //我不确定这是不是“height1”或“height” if（position == 0）{ height.setVisibility（View.GONE）; } else { height.setVisibility（View.VISIBLE）; } }
```
    @Override
    public void onNothingSelected(AdapterView<?> parent) {

    }
});

// if you want to add similar logic for weight spinner, do that with this : 
weight_spinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
    @Override
    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
        // put your code here for weight spinner
    }

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

    }
}); }
```
