Android的微调performClick onItemSelected [英] android spinner performClick onItemSelected

问题描述

我有一个小问题，一个微调。

I have a little problem with a spinner.

我创建了一个微调用户点击一个按钮。该微调显示，它应该是，但是当 onItemSelected 应该叫什么也不会发生。

I create a Spinner the user click a Button. The Spinner is shown as it should be, but when onItemSelected should be called nothing happens.

下面是code

public void setUpSpinner(){
    spinner = new Spinner(this);
    CustomArrayAdapter<String> adapter = new CustomArrayAdapter<String>(this,     android.R.layout.simple_spinner_item, getAsStrings());
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner.setAdapter(adapter);
    spinner.setOnItemSelectedListener(this);
}

public void onClick(View view) {       
    spinner.performClick();
}

public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {        
    String getName = (String) spinner.getSelectedItem();
    getListFromName(getName);
}

任何人都知道这里有什么问题？

Anyone knows what is wrong here?

感谢你们。
