Android中SwipeToLoadLayout的使用

SwipeToLoadLayout輕松定制自己的刷新效果，且子布局不在局限只是可以滑動的布局（如ListView， ScrollVie，RecyclerView）。

Android Studio中使用

Gradle中添加　compile 'com.github.Aspsine:SwipeToLoadLayout:1.0.4'

自定義刷新、加載的效果

SwipeToLoadLayout提供了一套接口，自定義的View只需要實現(xiàn)相應(yīng)的接口就好了，頭實現(xiàn)SwipeRefreshHeaderLayout，尾實現(xiàn)SwipeLoadMoreFooterLayout即可。

public class RefreshHeaderView extends SwipeRefreshHeaderLayout {

    private ImageView ivArrow;

    private TextView tvRefresh;

    private ProgressBar progressBar;

    private int mHeaderHeight;

    private Animation rotateUp;

    private Animation rotateDown;

    private boolean rotated = false;

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

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

    public RefreshHeaderView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        mHeaderHeight = getResources().getDimensionPixelOffset(R.dimen.refresh_header_height_60);
        rotateUp = AnimationUtils.loadAnimation(context, R.anim.rotate_up);
        rotateDown = AnimationUtils.loadAnimation(context, R.anim.rotate_down);
    }

    @Override
    protected void onFinishInflate() {
        super.onFinishInflate();

        tvRefresh = (TextView) findViewById(R.id.tvRefresh);
        ivArrow = (ImageView) findViewById(R.id.ivArrow);
        progressBar = (ProgressBar) findViewById(R.id.progressbar);
    }

    @Override
    public void onRefresh() {
        ivArrow.clearAnimation();
        ivArrow.setVisibility(GONE);
        progressBar.setVisibility(VISIBLE);
        tvRefresh.setText("正在刷新...");
    }

    @Override
    public void onPrepare() {
        Log.d("WeiboRefreshHeaderView", "onPrepare()");
    }

    @Override
    public void onMove(int y, boolean isComplete, boolean automatic) {
        if (!isComplete) {
            ivArrow.setVisibility(VISIBLE);
            progressBar.setVisibility(GONE);
            if (y > mHeaderHeight) {
                tvRefresh.setText("釋放刷新");
                if (!rotated) {
                    ivArrow.clearAnimation();
                    ivArrow.startAnimation(rotateUp);
                    rotated = true;
                }
            } else if (y < mHeaderHeight) {
                if (rotated) {
                    ivArrow.clearAnimation();
                    ivArrow.startAnimation(rotateDown);
                    rotated = false;
                }
                tvRefresh.setText("下拉刷新");
            }
        }
    }

    @Override
    public void onRelease() {
        Log.d("WeiboRefreshHeaderView", "onRelease()");
    }

    @Override
    public void onComplete() {
        rotated = false;
        ivArrow.clearAnimation();
        ivArrow.setVisibility(GONE);
        progressBar.setVisibility(GONE);
        tvRefresh.setText("刷新完成");
    }

    @Override

        ivArrow.setVisibility(GONE);
        progressBar.setVisibility(GONE);
        tvRefresh.setText("下拉刷新");
    }
}

public class LoadMoreFooterView extends SwipeLoadMoreFooterLayout{

    private TextView tvLoadMore;

    private int mHeaderHeight;

    public LoadMoreFooterView(Context context) {
        super(context);

            }
        }

    }

    @Override

        Log.d("LoadMoreFooterView", "onReset()");
    }
}

header和footer的xml

Activity的xml

注意：刷新目標、頭尾的id不能更改只能是swipeToLoadLayout、swipe_refresh_header、swipe_load_more_footer

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/colorPrimary">

    <com.aspsine.swipetoloadlayout.SwipeToLoadLayout
        android:id="@+id/swipeToLoadLayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <include
            android:id="@id/swipe_refresh_header"
            layout="@layout/layout_weibo_header"/>

        <TextView
            android:id="@id/swipe_target"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="#FFFFFF"
            android:gravity="center"
            android:text="下拉刷新"
            android:textSize="24sp"/>

        <include
            android:id="@id/swipe_load_more_footer"
            layout="@layout/layout_load_more_footer"/>

    </com.aspsine.swipetoloadlayout.SwipeToLoadLayout>

</RelativeLayout>

代碼中調(diào)用

public class RefreshActivity extends AppCompatActivity implements OnRefreshListener, OnLoadMoreListener {

    private SwipeToLoadLayout swipeToLoadLayout;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_weibo_refresh);

        swipeToLoadLayout = (SwipeToLoadLayout) findViewById(R.id.swipeToLoadLayout);

        swipeToLoadLayout.setOnRefreshListener(this);
        swipeToLoadLayout.setOnLoadMoreListener(this);

        swipeToLoadLayout.postDelayed(new Runnable() {
            @Override
            public void run() {
                swipeToLoadLayout.setRefreshing(true);
            }
        }, 100);


    }

    //刷新
    @Override
    public void onRefresh() {
        swipeToLoadLayout.postDelayed(new Runnable() {
            @Override
            public void run() {
                swipeToLoadLayout.setRefreshing(false);
            }
        }, 3000);
    }

    //加載更多
    @Override
    public void onLoadMore() {
        swipeToLoadLayout.postDelayed(new Runnable() {
            @Override
            public void run() {
                swipeToLoadLayout.setLoadingMore(false);
            }
        }, 3000);
    }
}
