我在Spinners中保留了一个单独的数组列表。这样我就可以在数组列表上执行indexOf，然后使用该值在Spinner中设置选择。

你也可以用这个，

String[] baths = getResources().getStringArray(R.array.array_baths);
mSpnBaths.setSelection(Arrays.asList(baths).indexOf(value_here));

你必须传递你的自定义适配器的位置，如REPEAT[position]。它能正常工作。

为了让应用程序记住最后选择的微调值，你可以使用下面的代码:

Below code reads the spinner value and sets the spinner position accordingly. public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); int spinnerPosition; Spinner spinner1 = (Spinner) findViewById(R.id.spinner1); ArrayAdapter<CharSequence> adapter1 = ArrayAdapter.createFromResource( this, R.array.ccy_array, android.R.layout.simple_spinner_dropdown_item); adapter1.setDropDownViewResource(android.R.layout.simple_list_item_activated_1); // Apply the adapter to the spinner spinner1.setAdapter(adapter1); // changes to remember last spinner position spinnerPosition = 0; String strpos1 = prfs.getString("SPINNER1_VALUE", ""); if (strpos1 != null || !strpos1.equals(null) || !strpos1.equals("")) { strpos1 = prfs.getString("SPINNER1_VALUE", ""); spinnerPosition = adapter1.getPosition(strpos1); spinner1.setSelection(spinnerPosition); spinnerPosition = 0; } And put below code where you know latest spinner values are present, or somewhere else as required. This piece of code basically writes the spinner value in SharedPreferences. Spinner spinner1 = (Spinner) findViewById(R.id.spinner1); String spinlong1 = spinner1.getSelectedItem().toString(); SharedPreferences prfs = getSharedPreferences("WHATEVER", Context.MODE_PRIVATE); SharedPreferences.Editor editor = prfs.edit(); editor.putString("SPINNER1_VALUE", spinlong1); editor.commit();

I had the same issue when trying to select the correct item in a spinner populated using a cursorLoader. I retrieved the id of the item I wanted to select first from table 1 and then used a CursorLoader to populate the spinner. In the onLoadFinished I cycled through the cursor populating the spinner's adapter until I found the item that matched the id I already had. Then assigned the row number of the cursor to the spinner's selected position. It would be nice to have a similar function to pass in the id of the value you wish to select in the spinner when populating details on a form containing saved spinner results.

@Override
public void onLoadFinished(Loader<Cursor> loader, Cursor cursor) {  
  adapter.swapCursor(cursor);

  cursor.moveToFirst();

 int row_count = 0;

 int spinner_row = 0;

  while (spinner_row < 0 || row_count < cursor.getCount()){ // loop until end of cursor or the 
                                                             // ID is found 

    int cursorItemID = bCursor.getInt(cursor.getColumnIndexOrThrow(someTable.COLUMN_ID));

    if (knownID==cursorItemID){
    spinner_row  = row_count;  //set the spinner row value to the same value as the cursor row 

    }
cursor.moveToNext();

row_count++;

  }

}

spinner.setSelection(spinner_row ); //set the selected item in the spinner

}
