從微調框中選擇項目以顯示編輯文本

我試圖顯示一個EditText，當一個微調框中的某個項目被選中。到目前爲止，我已經創建了微調器和EditText，但我不知道我的下一步是什麼。我不想在EditText中顯示選擇，我只想顯示EditText字段。從微調框中選擇項目以顯示編輯文本

@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()); 

}

這也是我在我的字符串數組+希望只當選擇ITEM2

<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>

變化對象名EDITTEXT或EDIT1或etName，'EditText'是不允許的。 – MKJParekh

您應該設置EDITTEXT的能見度不可見或用XML取代了，更好地滿足您的需求。那麼你可以使用下面使其出現：

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

你必須設置上的EditText onItemSelected文本顯示的EditText框。首先按更改MKJParekh建議。

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

我遵循了MKJParekh的說法，並且嘗試了您的建議，但現在告訴我editText無法解析 – user1643333

@ user1643333請顯示您的代碼 –

獲取從旋轉選定的值，

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

現在可以顯示在編輯文本這個字符串值，

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

 @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)

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);

另外，如果你想檢查項目的微調選擇的值時，「valsel」包含值。只是敬酒的中檔。

EditText height1，weight1，height，weight; Spinner height_spinner， weight_spinner;字符串heightInputString，weightInputString;按鈕 calculatebmi;

@Override保護無效的onCreate（Bundle savedInstanceState）{ super.onCreate（savedInstanceState）; 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(); }

空隙setupSpinners（）{ height_spinner.setOnItemSelectedListener（新AdapterView.OnItemSelectedListener（）{ @Override 公共無效onItemSelected（適配器視圖父，瀏覽視圖，INT位置，長ID）{// IE如果在高度微調CM被選中我想隱藏第二個高度edittext字段 //我不確定這是爲了「height1」還是「height」 if（position == 0）{ height .setVisibility（View.GONE）; } else { height.setVisibility（View.VISIBLE）; } }的EditText的

@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) { 

    } 
}); }
