刚上班2,3天还没从放假的节奏中缓过来,总觉得懒洋洋的哈哈哈。

继续之前的介绍一些好用/有意思/有学习意义的干活给大家,今天是Swipecards

地址:https://github.com/Diolor/Swipecards

效果:



在国内的一些社交类的App中也见过类似的实现。

How to use?

Gradle:

[code]dependencies {
    compile 'com.lorentzos.swipecards:library:X.X.X@aar'
}


Eclipse的话就要把源码都Copy进去了(还好东西不多)



简单的介绍下怎么使用

首先,在你的布局里面拽入这个控件

[code] <com.lorentzos.flingswipe.SwipeFlingAdapterView
        android:id="@+id/frame"
        android:background="#ffeee9e2"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:rotation_degrees="15.5"
        tools:context=".MyActivity" />


他有一些自定义的标签,像这样

[code] <declare-styleable name="SwipeFlingAdapterView">
        <attr name="SwipeFlingStyle" format="reference"/>
        <attr name="rotation_degrees" format="float"/>
        <attr name="min_adapter_stack" format="integer"/>
        <attr name="max_visible" format="integer"/>
    </declare-styleable>


都是一些对控件进行配置的,具体的属性大家可以看下源码,这里就不做解释了

接下来那我们就在事物的Activity里获取这个控件(这边是用依赖注入做的)

[code] @InjectView(R.id.frame) SwipeFlingAdapterView flingContainer;


再给我们的控件添加数据源

[code]        al = new ArrayList<>();
        al.add("php");
        al.add("c");
        al.add("python");
        al.add("java");
        al.add("html");
        al.add("c++");
        al.add("css");
        al.add("javascript");

        arrayAdapter = new ArrayAdapter<>(this, R.layout.item, R.id.helloText, al );

        flingContainer.setAdapter(arrayAdapter);


添加控件的事件监听

当卡片被移除,无论左右都会触发removeFirstObjectInAdapter()

左边触发onLeftCardExit()

右边出发onRightCardExit()

没数据了调用onAdapterAboutToEmpty()

滑动的过程中调用onScroll()

[code] flingContainer.setFlingListener(new SwipeFlingAdapterView.onFlingListener() {
            @Override
            public void removeFirstObjectInAdapter() {
                // this is the simplest way to delete an object from the Adapter (/AdapterView)
                Log.d("LIST", "removed object!");
                al.remove(0);
                arrayAdapter.notifyDataSetChanged();
            }

            @Override
            public void onLeftCardExit(Object dataObject) {
                //Do something on the left!
                //You also have access to the original object.
                //If you want to use it just cast it (String) dataObject
                makeToast(MyActivity.this, "Left!");
            }

            @Override
            public void onRightCardExit(Object dataObject) {
                makeToast(MyActivity.this, "Right!");
            }

            @Override
            public void onAdapterAboutToEmpty(int itemsInAdapter) {
                // Ask for more data here
                al.add("XML ".concat(String.valueOf(i)));
                arrayAdapter.notifyDataSetChanged();
                Log.d("LIST", "notified");
                i++;
            }

            @Override
            public void onScroll(float scrollProgressPercent) {
                View view = flingContainer.getSelectedView();
                view.findViewById(R.id.item_swipe_right_indicator).setAlpha(scrollProgressPercent < 0 ? -scrollProgressPercent : 0);
                view.findViewById(R.id.item_swipe_left_indicator).setAlpha(scrollProgressPercent > 0 ? scrollProgressPercent : 0);
            }
        });


还支持点击时间(就是没有滑,单纯的点)

[code]  flingContainer.setOnItemClickListener(new SwipeFlingAdapterView.OnItemClickListener() {
            @Override
            public void onItemClicked(int itemPosition, Object dataObject) {
                makeToast(MyActivity.this, "Clicked!");
            }
        });

    }
