翻翻git之---好看的卡片切換庫 Swipecards

剛上班2，3天還沒從放假的節奏中緩過來，總覺得懶洋洋的哈哈哈。

繼續之前的介紹一些好用/有意思/有學習意義的干活給大家，今天是Swipecards

效果：

在國內的一些社交類的App中也見過類似的實現。

How to use?

Gradle:

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

Eclipse的話就要把源碼都Copy進去了（還好東西不多）

簡單的介紹下怎麼使用<喎?http://www.2cto.com/kf/ware/vc/" target="_blank" class="keylink">vcD4NCjxwPsrXz8ijrNTaxOO1xLK8vtbA78Pm16fI69XiuPa/2Lz+PC9wPg0KPHByZSBjbGFzcz0="brush:java;">

他有一些自定義的標簽，像這樣

都是一些對控件進行配置的，具體的屬性大家可以看下源碼，這裡就不做解釋了

接下來那我們就在事物的Activity裡獲取這個控件(這邊是用依賴注入做的)

 @InjectView(R.id.frame) SwipeFlingAdapterView flingContainer;

再給我們的控件添加數據源

        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);

添加控件的事件監聽
當卡片被移除，無論左右都會觸發removeFirstObjectInAdapter()

左邊觸發onLeftCardExit()

右邊出發onRightCardExit()

沒數據了調用onAdapterAboutToEmpty()

滑動的過程中調用onScroll()

 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);
            }
        });

還支持點擊時間（就是沒有滑，單純的點）

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

    }

源碼在最上面的連接裡有！！！

謝謝！！！
