微調不會響應點擊...即使onItemSelected被調用？

Question

（我不知道這是否允許在這裏，我是新的）

我在stackoverflow上發現了一個老問題，問題沒有得到正確的答案，而且我面對同樣的問題。因此，我真的很感激，如果有人可以看看它，非常感謝！

Spinner won't respond to clicks...even though onItemSelected is called?

UPDATE：

我自己的代碼，那麼我想，以防止通過在開始運行我onItemSelected（）方法，所以我做一樣的人問這個問題。我嘗試了一下我的代碼，看看它是否會改變什麼，但沒有運氣..老實說，我不知道什麼是錯的，我仍然是一個初學者，所以我真的沒有線索做什麼..

這裏是我的代碼：

public class WidgetConfig extends Activity implements OnItemSelectedListener{ 

static EditText info; 
private static final String[] paths = { "10", "12", "14", "16", "18", "20", 
    "22", "24", "26", "28", "30", "32", "34", "36", "38", "40", "50", "60"}; 

private static final String TAG = "MyActivity"; 

int mAppWidgetId = AppWidgetManager.INVALID_APPWIDGET_ID; 

private ArrayList<String> mMyTypes = null; 
private ArrayAdapter<String> mMyAdapter = null; 
private Spinner mMyTypeSpinner = null; 
// hack for spinner 
boolean isFirstRunWithSpinner = true; 


public WidgetConfig() { 
    super(); 
} 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    super.onCreate(savedInstanceState); 

    Log.v(TAG, "onCreate() started"); 

    setContentView(R.layout.widgetconfig); 

    context = WidgetConfig.this; 

    // back button = cancel 
    setResult(RESULT_CANCELED); 

    //-------------------------------------------------- 



    mMyTypeSpinner = (Spinner) findViewById(R.id.TxtSizeSP); 

    mMyTypes = new ArrayList<String>(); 
    mMyTypes.add("Test string"); 

    mMyAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, paths); 
    mMyAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
    mMyTypeSpinner.setAdapter(mMyAdapter); 


    // spinner listener 
    mMyTypeSpinner.setOnItemSelectedListener(this); 




} // onCreate finished 

public void onItemSelected(AdapterView<?> parent, View v, int position, long id) { 
    Log.v(TAG, "OnItemselected started"); 

    if(isFirstRunWithSpinner) { isFirstRunWithSpinner = false; return; } 

    RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget); 

    AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context); 

    switch (position) { 
    case 0: 
     info.setTextSize(10.0f); 
     views.setFloat(R.id.tvConfigInput, "setTextSize", 10); 
     Log.v(TAG, "position 0 chosed"); 
     break; 

     ... 

     break; 
    case 17: 
     info.setTextSize(28.0f); 
     views.setFloat(R.id.tvConfigInput, "setTextSize", 60); 
     break; 
    } 

    //update widget with spinner input 
    Log.v(TAG, "update size start"); 
    appWidgetManager.updateAppWidget(mAppWidgetId, views); 
    Log.v(TAG, "update size over"); 



    } 


public void onNothingSelected(AdapterView<?> arg0) { 

} 

    ... 

} 

}

你試過嗎？ ：

if(isFirstRunWithSpinner) { 
isFirstRunWithSpinner = false; 
}else{ 
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget); 

AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(context); 

switch (position) { 
case 0: 
    info.setTextSize(10.0f); 
    views.setFloat(R.id.tvConfigInput, "setTextSize", 10); 
    Log.v(TAG, "position 0 chosed"); 
    break; 

    ... 

    break; 
case 17: 
    info.setTextSize(28.0f); 
    views.setFloat(R.id.tvConfigInput, "setTextSize", 60); 
    break; 
} 

//update widget with spinner input 
Log.v(TAG, "update size start"); 
appWidgetManager.updateAppWidget(mAppWidgetId, views); 
Log.v(TAG, "update size over"); 
}
