android+studio侧边菜单栏

以下是一个使用Android Studio创建侧边菜单栏的示例代码：

package com.example.slidemenu.view;

import android.content.Context;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.view.View;import android.widget.FrameLayout;
import android.widget.Scroller;

public class SlideMenu extends FrameLayout {
    private View menuView;
    private View mainView;
    private int menuWidth;
    private Scroller scroller;

    public SlideMenu(Context context) {
        this(context, null);
    }

    public SlideMenu(Context context, AttributeSet attrs) {
        this(context, attrs, 0);
    }

    public SlideMenu(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        scroller = new Scroller(context);
    }

    @Override
    protected void onFinishInflate() {
        super.onFinishInflate();
        menuView = getChildAt(0);
        mainView = getChildAt(1);
        menuWidth = menuView.getLayoutParams().width;
    }

    @Override
    protected void onLayout(boolean changed, int left, int top, int right, int bottom) {
        super.onLayout(changed, left, top, right, bottom);
        menuView.layout(-menuWidth, 0, 0, bottom);
        mainView.layout(0,0, right, bottom);
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                break;
            case MotionEvent.ACTION_MOVE:
                break;
            case MotionEvent.ACTION_UP:
                break;
        }
        return true;
    }
}
