Question

我使用SwipeRefreshLayout并希望在创建Activity后将其设置为刷新，但setRefreshing(true)不起作用。所以我在SO中找到了这个问题：SwipeRefreshLayout setRefreshing not showing indicator initially。

我选择覆盖SwipeRefreshLayout来存储本地刷新标志：

public class MyRefreshLayout extends SwipeRefreshLayout {

    public MyRefreshLayout(Context context) {
        super(context);
    }

    public MyRefreshLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    private boolean mMeasured = false;
    private boolean mPreMeasureRefreshing = false;

    @Override
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        if (!mMeasured) {
            mMeasured = true;
            setRefreshing(mPreMeasureRefreshing);
        }
    }


    @Override
    public void setRefreshing(boolean refreshing) {
        if (mMeasured) {
            super.setRefreshing(refreshing);
        } else {
            mPreMeasureRefreshing = refreshing;
        }
    }
}

我会在创建活动后刷新，但不会调用OnRefreshListener。这是我的初始代码：

mRefreshLayout = (MyRefreshLayout) findViewById(R.id.refresh_layout);
mRefreshLayout.setColorSchemeResources(R.color.holo_blue_dark, R.color.holo_blue_light, R.color.holo_green_light, R.color.holo_green_light);
mRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
    @Override
    public void onRefresh() {
          mRefreshLayout.setRefreshing(false);
    }
});

mRefreshLayout.setRefreshing(true);

我无法找到相关问题，请帮助，谢谢！

Answer 1

我发现我误解了OnRefreshListener。医生说：

希望在滑动手势正确触发刷新时收到通知的类应该实现此接口。

所以如果我打电话给mRefreshLayout.setRefreshing(true);。这不是一个轻扫手势，听众不会被召唤！

你可以在Min2的答案中找到关于如何调用监听器的解决方案

SwipeRefreshLayout trigger programmatically

SwipeRefreshLayout不会调用刷新侦听器
