对话框说明
使用 DialogFragment 实现，创建 DialogUtils 工具类

普通对话框

 AlertDialog.Builder builder = new AlertDialog.Builder(mContext);
        builder.setTitle("温馨提醒");
        builder.setMessage("您已经打开 android.support.v7.app.AlertDialog");
        builder.setNegativeButton("取消", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialogInterface, int i) {
                dialogInterface.dismiss();

            }
        });
        builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialogInterface, int i) {

                dialogInterface.dismiss();


            }
        });
        builder.show();

横向进度对话框

  progressHortionalDialog = new ProgressDialog(mContext, android.support.v7.app.AlertDialog.BUTTON_NEUTRAL);
        if (title != null) {
            progressHortionalDialog.setTitle(title);
        }

        if (message != null) {
            progressHortionalDialog.setMessage(message);
        }
        progressHortionalDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        progressHortionalDialog.setIndeterminate(false);

        progressHortionalDialog.setMax(100);

        progressHortionalDialog.setCanceledOnTouchOutside(false);

        progressHortionalDialog.setCancelable(true);

        progressHortionalDialog.setOnCancelListener(new DialogInterface.OnCancelListener() {
            @Override
            public void onCancel(DialogInterface dialog) {

                dialog.dismiss();


            }
        });

常用下拉刷新

xml 中将 AbPullToRefreshView 套在继承与ScrollView的组件最外层。例如 ScrollView ListView WebView GridView

 <com.ningcui.mylibrary.viewLib.refresh.AbPullToRefreshView
        android:id="@+id/pulltofreshView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"

        >

        <ListView

            android:id="@+id/pull_listView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:background="@color/white"
            android:divider="@color/gray_bg"
            android:dividerHeight="4px" />


    </com.ningcui.mylibrary.viewLib.refresh.AbPullToRefreshView>

设置下拉刷新功能


        pulltofreshView.setLoadMoreEnable(true);
        pulltofreshView.setPullRefreshEnable(true);
        pulltofreshView.setOnHeaderRefreshListener(new AbPullToRefreshView.OnHeaderRefreshListener() {
            @Override
            public void onHeaderRefresh(AbPullToRefreshView abPullToRefreshView) {

                getData();


            }
        });

        pulltofreshView.setOnFooterLoadListener(new AbPullToRefreshView.OnFooterLoadListener() {
            @Override
            public void onFooterLoad(AbPullToRefreshView abPullToRefreshView) {


                loadData();


            }
        });

加载数据结束
pulltofreshView.onFooterLoadFinish();
刷新数据结束
pulltofreshView.onHeaderRefreshFinish();

自定义SwiperefreshLayout 支持加载

使用方法

 // 设置下拉进度的背景颜色，默认就是白色的
        swipeRefreshView.setProgressBackgroundColorSchemeResource(android.R.color.white);
        // 设置下拉进度的主题颜色
        swipeRefreshView.setColorSchemeResources(R.color.colorAccent, R.color.colorPrimary, R.color.colorPrimaryDark);

        // 下拉时触发SwipeRefreshLayout的下拉动画，动画完毕之后就会回调这个方法
        swipeRefreshView.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {

              
                // TODO 获取数据
                final Random random = new Random();
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        mList.add(0, "测试数据" + random.nextInt(100) + "号");
                        mAdapter.notifyDataSetChanged();

                        Toast.makeText(SwipeRefreshLayoutActivity.this, "刷新了一条数据", Toast.LENGTH_SHORT).show();

                        // 加载完数据设置为不刷新状态，将下拉进度收起来
                        swipeRefreshView.setRefreshing(false);
                    }
                }, 1200);


            }
        });


        // 设置下拉加载更多
        swipeRefreshView.setOnLoadListener(new SwipeRefreshView.OnLoadListener() {
            @Override
            public void onLoad() {
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {

                        // 添加数据
                        for (int i = 30; i < 35; i++) {
                            mList.add("测试数据" + i + "号");
                            // 这里要放在里面刷新，放在外面会导致刷新的进度条卡住
                            mAdapter.notifyDataSetChanged();
                        }

                        Toast.makeText(SwipeRefreshLayoutActivity.this, "加载了" + 5 + "条数据", Toast.LENGTH_SHORT).show();

                        // 加载完数据设置为不加载状态，将加载进度收起来
                        swipeRefreshView.setLoading(false);
                    }
                }, 1200);
            }
        });

说明： SwiperefreshLayout与 ViewPager 等横向滑动混用会有异常。需要对ViewPager 进行一些修改后续会提及
