如何为微调器捕获Android中的onClick事件 [英] How to capture onClick event in Android for a spinner

问题描述

我想在用户选择微调器值时捕获onClick事件.

I want to capture the onClick event when the user selects a spinner value.

我尝试实现OnClickListener并使用以下代码:

I've tried implementing OnClickListener and using the following code:

@Override
public void onClick(final View view) {
  if (view == countrySpinner) {
    Toast.makeText(this, "Override OK!", 3);
  }
}

并绑定:

countrySpinner.setOnClickListener(this);

这可以编译，但是我得到一个RuntimeException，建议我对AdapterView使用OnItemClickListener而不是OnClickListener.

This compiles, but I get a RuntimeException advising me to use OnItemClickListener rather than OnClickListener for an AdapterView.

如何捕获该onClick事件?

How can I capture that onClick event?

推荐答案

而不是设置微调器的OnClickListener，请尝试设置OnTouchListener和OnKeyListener.

Instead of setting the spinner's OnClickListener,try setting OnTouchListener and OnKeyListener.

spinner.setOnTouchListener(spinnerOnTouch);
spinner.setOnKeyListener(spinnerOnKey);

和听众:

private View.OnTouchListener spinnerOnTouch = new View.OnTouchListener() {
    public boolean onTouch(View v, MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_UP) {
            //Your code
        }
        return false;
    }
};
private static View.OnKeyListener spinnerOnKey = new View.OnKeyListener() {
    public boolean onKey(View v, int keyCode, KeyEvent event) {
        if (keyCode == KeyEvent.KEYCODE_DPAD_CENTER) {
            //your code
            return true;
        } else {
            return false;
        }
    }
};
