java setmodal 不管用_java – 无法动态设置setVisibility()参数

我正在设置一个按钮的可见性,如下所示：

public Bundle setActivityState(Bundle bundle){

startBtn = (Button) findViewById(R.id.startSensorsBtn);

startBtn.setVisibility(

getVisibilityState(bundle,PersistanceConstants.START_BTN_STATE)

);

return bundle;

}

public int getVisibilityState(Bundle bundle,String keyName){

if (bundle.getInt(keyName) == View.VISIBLE){

return View.VISIBLE;

} else if (bundle.getInt(keyName) == View.INVISIBLE){

return View.INVISIBLE;

} else if (bundle.getInt(keyName) == View.GONE){

return View.GONE;

}

return 0;

}

但我收到错误：

Must be one of: View.VISIBLE,View.INVISIBLE,View.GONE less... (Ctrl+F1)

Reports two types of problems:

- Supplying the wrong type of resource identifier. For example,when calling Resources.getString(int id),you should be passing R.string.something,not R.drawable.something.

- Passing the wrong constant to a method which expects one of a specific set of constants. For example,when calling View#setLayoutDirection,the parameter must be android.view.View.LAYOUT_DIRECTION_LTR or android.view.View.LAYOUT_DIRECTION_RTL.

而打电话

getVisibilityState(bundle,PersistanceConstants.START_BTN_STATE)

我不知道如何解决这个问题.我明白,它期待一组给定的值,但我知道的只是传递一个int.这里可以做些什么？
