Android --SwipeRefreshLayout 下拉刷新

1、Layout

   <android.support.v4.widget.SwipeRefreshLayout
        android:id="@+id/id_swipe_ly"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >
    <com.github.mikephil.charting.charts.LineChart
        android:id="@+id/chart1"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
    </android.support.v4.widget.SwipeRefreshLayout>

2、初始化

/**
     * 下拉刷新SwipeRefreshLayout
     */
    private SwipeRefreshLayout mswipeLayout;

mswipeLayout =(SwipeRefreshLayout)findViewById(R.id.id_swipe_ly);
        mswipeLayout.setOnRefreshListener(this);
        mswipeLayout.setColorSchemeResources(android.R.color.holo_blue_light, android.R.color.holo_blue_light,
                android.R.color.holo_blue_light, android.R.color.holo_blue_light);

3、继承接口

implements OnChartValueSelectedListener
        ,SwipeRefreshLayout.OnRefreshListener

    @Override
    public void onRefresh()
    {
        mHandler.sendEmptyMessageDelayed(0, 1000);
    }
