獲取微調選定的項目文本？

Question

如何獲得微調選定項目的文本？

當我點擊保存按鈕時，我必須在我的微調器中選擇的項目上獲得文本。 我需要的文字不是索引。

Answer 1

Spinner spinner = (Spinner)findViewById(R.id.spinner); 
String text = spinner.getSelectedItem().toString(); 

Answer 2

你必須使用索引和適配器找出文本你有

見this example of Spinner

public class MyOnItemSelectedListener implements OnItemSelectedListener { 

    public void onItemSelected(AdapterView<?> parent, 
     View view, int pos, long id) { 
     Toast.makeText(parent.getContext()), "The planet is " + 
      parent.getItemAtPosition(pos).toString(), Toast.LENGTH_LONG).show(); 
    } 

    public void onNothingSelected(AdapterView parent) { 
     // Do nothing. 
    } 
} 

Answer 3

微調將返回該陣列的整數值。您必須根據索引檢索字符串值。

Spinner MySpinner = (Spinner)findViewById(R.id.spinner); 
Integer indexValue = MySpinner.getSelectedItemPosition();

使用本

Answer 5

TextView textView = (TextView)mySpinner.getSelectedView(); 
String result = textView.getText().toString(); 

Answer 6

TextView textView = (TextView) spinActSubTask.getSelectedView().findViewById(R.id.tvProduct); 

String subItem = textView.getText().toString(); 

Answer 7

一個行版本：

String text = ((Spinner)findViewById(R.id.spinner)).getSelectedItem().toString(); 

更新： 如果您使用SDK 26（或更新版本）編譯項目，則可以刪除轉換。

String text = findViewById(R.id.spinner).getSelectedItem().toString(); 

Answer 8

spinner_button.setOnItemSelectedListener(new OnItemSelectedListener() { 
     @Override 
     public void onItemSelected(AdapterView<?>arg0, View view, int arg2, long arg3) { 

      String selected_val=spinner_button.getSelectedItem().toString(); 

      Toast.makeText(getApplicationContext(), selected_val , 
        Toast.LENGTH_SHORT).show(); 
     } 

     @Override 
     public void onNothingSelected(AdapterView<?> arg0) { 
      // TODO Auto-generated method stub 

     } 
    }); 

} 

Answer 9

對於基於一個CursorAdapter紡紗：

• 獲得所選項目編號：spinner.getSelectedItemId()

• 從數據庫中獲取的項目名稱，例如：

  public String getCountryName(int pId){ 
      Cursor cur = mDb.query(TABLE, new String[]{COL_NAME}, COL_ID+"=?", new String[]{pId+""}, null, null, null); 
      String ret = null; 
      if(cur.moveToFirst()){ 
       ret = cur.getString(0); 
      } 
      cur.close(); 
      return ret; 
  } 
  

Answer 10

對於那些已經基於HashMap的微調：

((HashMap)((Spinner)findViewById(R.id.YourSpinnerId)).getSelectedItem()).values().toArray()[0].toString(); 

如果你是在一個片段，適配器或大於主要活動以外的其他類，使用此：

((HashMap)((Spinner)YourInflatedLayoutOrView.findViewById(R.id.YourSpinnerId)).getSelectedItem()).values().toArray()[0].toString(); 

它只是爲指導;您應該在onClick方法之前找到您的視圖的ID爲。

Answer 11

Spinner spinner = (Spinner) findViewById(R.id.yourspinnerid); 
String text = spinner.getSelectedItem().toString();
