Android滑動卡片效果：Swipecards

一個類似于 Tinder的Android庫，用于創建滑動卡片效果。 您可以向左或向右滑動來切換喜歡或不喜歡的內容。

//implement the onFlingListener
public class MyActivity extends Activity {
    ...

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        ...

        //add the view via xml or programmatically
        SwipeFlingAdapterView flingContainer = (SwipeFlingAdapterView) findViewById(R.id.frame);

        al = new ArrayList<String>();
        al.add("php");
        al.add("c");
        al.add("python");
        al.add("java");

        //choose your favorite adapter
        arrayAdapter = new ArrayAdapter<String>(this, R.layout.item, R.id.helloText, al );

        //set the listener and the adapter
        flingContainer.setAdapter(arrayAdapter);
        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
                Toast.makeText(MyActivity.this, "Left!", Toast.LENGTH_SHORT).show();
            }

            @Override
            public void onRightCardExit(Object dataObject) {
                Toast.makeText(MyActivity.this, "Right!", Toast.LENGTH_SHORT).show();
            }

            @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++;
            }
        });

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