通过Android中的触摸,像SKOUT和从一个视图滑动到另一个视图的菜单

标签: android android-layout android-fragments android-viewpager slidingdrawer

我想实现一个像FB或G + app这样的滑动菜单,我找到了一些来自FB Menu Demohttps://github.com/jfeinstein10/SlidingMenu的示例代码

这些都是好的开始,但我需要额外的东西。就像这里一样,它仅适用于单击菜单按钮,但我也希望通过手势移动它。 我希望有一个中心视图的行为,并且在向右移动该中心时,将出现一个视图,并且在向左移动时,菜单将出现。假设有三个视图A,B,C,当我向左滑动C然后出现A时,当我向右滑动C然后出现B. C位于A和B的中间。

1.中间视图向右移动

That screen is in the middle向右移动Menu appear

2.将中间视图移向左侧

Move towards the left by touch向左移动Third view

现在我的问题是:开发类似观点的最佳做法是什么。我从某人那里听说我应该使用片段和View寻呼机。那么我该如何开发呢?是否有人做过任何样本实施?任何帮助和建议表示赞赏。

供参考,请参阅此应用使用此类型的滑动黑白视图Skout app

最简单的解决方案可能是使用内置边框滑动的android-undergarment,基于项目自述文件:

  

用户还可以通过从屏幕左侧滑动的挡板控制抽屉打开抽屉,并从右侧执行相同操作以关闭抽屉。如果要阻止此触摸功能,可以调用setDrawerEnabled(false)。

您只需在要移动的视图上使用TranslateAnimation,然后弹出淡入淡出窗口,另一个弹出窗口显示您的菜单。我已经在我的应用程序中实现了它,它就像一个魅力。

代码

public class SlidingOptionsMenuActivity extends Activity {

    /**
     * Signifies that the menu is already visible
     */
    boolean alreadyShowing = false;
    /**
     * Width of the current window
     */
    private int windowWidth;
    /**
     * Height of the current window
     */
    private int windowHeight;
    /**
     * Reference of the {@link PopupWindow} which dims the screen
     */
    private PopupWindow fadePopup;
    /**
     * The translate animation
     */
    private Animation ta;
    /**
     * The view which needs to be translated
     */
    private RelativeLayout baseView;
    /**
     * Reference of the {@link LayoutInflater}

    LayoutInflater inflater;

    /*

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Display display = getWindowManager().getDefaultDisplay();
        windowWidth = display.getWidth();
        windowHeight = display.getHeight();
        inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        findViewById(R.id.btnOptions).setOnClickListener(new OnClickListener() {

            /*
             * (non-Javadoc)
             * 
             * @see android.view.View.OnClickListener#onClick(android.view.View)
             */
            @Override
            public void onClick(View v) {
                if(!alreadyShowing){
                    alreadyShowing = true;
                    openSlidingMenu();
                }
            }
        });
    }


    /**

    private void showFadePopup() {
        final View layout = inflater.inflate(R.layout.fadepopup, (ViewGroup) findViewById(R.id.fadePopup));
        fadePopup = new PopupWindow(layout, windowWidth, windowHeight, false);
        fadePopup.showAtLocation(layout, Gravity.NO_GRAVITY, 0, 0);
    }

    /**
     * Opens the sliding Menu
     */
    private void openSlidingMenu() {
        showFadePopup();
        // The amount of view which needs to be moved out. equivalent to the
        // width of the menu
        int width = (int) (windowWidth * 0.6f);
        translateView((float) (width));
        int height = LayoutParams.FILL_PARENT;
        // creating a popup
        final View layout = inflater.inflate(R.layout.option_popup_layout,(ViewGroup) findViewById(R.id.popup_element));

        final PopupWindow optionsPopup = new PopupWindow(layout, width, height, true);
        optionsPopup.setBackgroundDrawable(new PaintDrawable());

        optionsPopup.showAtLocation(layout, Gravity.NO_GRAVITY, 0, 0);

        optionsPopup.setOnDismissListener(new PopupWindow.OnDismissListener() {

            public void onDismiss() {
                //Removing the fade effect
                fadePopup.dismiss();    
                //to clear the previous animation transition in
                cleanUp();
                //move the view out
                translateView(0);
                //to clear the latest animation transition out

                alreadyShowing = false;
            }
        });
    }

    /**

    private void translateView(float right) {

        ta = new TranslateAnimation(0f, right, 0f, 0f);
        ta.setDuration(300);
        ta.setFillEnabled(true);
        ta.setFillAfter(true);

        baseView = (RelativeLayout) findViewById(R.id.baseView);
        baseView.startAnimation(ta);
        baseView.setVisibility(View.VISIBLE);
    }

    /**
     * Basic cleanup to avoid memory issues. Not everything is release after
     * animation, so to immediately release it doing it manually
     */
    private void cleanUp(){
        if (null != baseView) {
            baseView.clearAnimation();
            baseView = null;
        }
        if (null != ta) {
            ta.cancel();
            ta = null;
        }
        fadePopup = null;
    }

//END of file

希望这会有所帮助。

另一个我发现非常好的开源库SlidingMenu。它应该适合您的需要,因为您可以通过“菜单”单击和挡板滑动来打开和关闭抽屉。我发现将它与像ActionBarSherlockjohannilsson's android-actionbar库这样的Actionbar库集成只需更改库项目中的一行或两行代码。 SlidingMenu库的自述文件解释了如何与ABSherlock库集成。

值得注意的是,SlidingMenu示例项目演示了许多不同的抽屉打开关闭动画。这些是我在这种菜单/导航方式中看到的一些最好的动画。

有一种官方方式......有用且轻便(使用v4支持库):
