Android ListView在Item Long Click Release上运行事件

Question

我在ListView中使用OnItemClickListener和OnItemLongClickListener,现在我正在寻找一种方法来检测OnItemLongClick之后的释放动作,实现这一目标的最佳方法是什么？

当我接受@ g00dy回答时,我发现这个解决方案更符合我的需求,并将我的代码放在一个地方.

在我设置listView的Activity里面我正在这样做:

MyOnLongClickListener myListener = new MyOnLongClickListener(this);
listView.setOnItemLongClickListener(myListener);
listView.setOnTouchListener(myListener.getReleaseListener());

所有的魔法发生在"MyOnLongClickListener"中:

public class MyOnLongClickListener implements AdapterView.OnItemLongClickListener {

    private View.OnTouchListener mReleaseListener = new OnReleaseListener();
    private boolean mEnabled = false;
    private Context mContext;

    public MyOnLongClickListener(Context context) {
        mContext = context;
    }

    @Override
    public boolean onItemLongClick(AdapterView<?> adapterView, View view, int i, long l) {
        Toast.makeText(mContext, "OnLongClick", Toast.LENGTH_SHORT).show();
        mEnabled = true;
        return true;
    }

    /**
     * Returns a listener for the release event.
     * @return
     */
    public View.OnTouchListener getReleaseListener() {
        return mReleaseListener;
    }

    /**
     * Listener for the Release event.
     */
    private class OnReleaseListener implements View.OnTouchListener {
        @Override
        public boolean onTouch(View view, MotionEvent motionEvent) {
            if(motionEvent.getAction() == android.view.MotionEvent.ACTION_UP) {
                if(mEnabled) {
                    Toast.makeText(mContext, "Release", Toast.LENGTH_SHORT).show();
                    /* Execute... */
                    mEnabled = false;
                    return true;
                }
            }
            return false;
        }
    }

}
