android 表单库SortableTableView详解，详细讲解，帮您上手就用

转载请注明出处：王亟亟的大牛之路

现在各种公司财务流程走到了手机端啊pad这一些产品上面，安卓画类似xls的库并不是太多（可能我见识少），看到一个Git上的库，觉得蛮好用的，尝试性的移植到了产品中去，写一下使用的心得

项目结构




实现效果：



Gradle:

compile 'de.codecrafters.tableview:tableview:0.9.5'

最低Minimum SDK-Version: 11 最新版本 0.9.5

如何使用这样的一个tableview?

<de.codecrafters.tableview.TableView
        xmlns:table="http://schemas.android.com/apk/res-auto"
        android:id="@+id/tableView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        table:columnCount="4" />

table:columnCount是你表单的列数，当然需要引入xmlns:table=”http://schemas.android.com/apk/res-auto”

还有其他一些属性，在attributes.xml文件里定义

<resources>
    <declare-styleable name="TableView">
        <attr name="columnCount" format="integer"/>
        <attr name="headerElevation" format="integer"/>
        <attr name="headerColor" format="color"/>
    </declare-styleable>
</resources>

我拿Demo包的代码来作为解释的例子

MainActivity

public class MainActivity extends AppCompatActivity {
    //放置数据的容器，每一个对象其实就是等于一行
    private static List<Car> CAR_LIST = new ArrayList<>();

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

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        if (toolbar != null) {
            setSupportActionBar(toolbar);
        }
        //自定义View绑定Id
        SortableCarTableView carTableView = (SortableCarTableView) findViewById(R.id.tableView);
        //填充数据
        carTableView.setDataAdapter(new CarTableDataAdapter(this, CAR_LIST));
        //添加监听事件
        carTableView.addDataClickListener(new CarClickListener());
    }

    //表单内的点触时间，以行为单位
    private class CarClickListener implements TableDataClickListener<Car> {

        @Override
        public void onDataClicked(int rowIndex, Car clickedData) {
            String carString = clickedData.getProducer().getName() + " " + clickedData.getName();
            Toast.makeText(MainActivity.this, carString, Toast.LENGTH_SHORT).show();
        }
    }

    //塞数据！！！
    static {
        CarProducer audi = new CarProducer(R.mipmap.audi, "Audi");
        Car audiA1 = new Car(audi, "A1", 150, 25000);
        Car audiA3 = new Car(audi, "A3", 120, 35000);
        Car audiA4 = new Car(audi, "A4", 210, 42000);
        Car audiA5 = new Car(audi, "S5", 333, 60000);
        Car audiA6 = new Car(audi, "A6", 250, 55000);
        Car audiA7 = new Car(audi, "A7", 420, 87000);
        Car audiA8 = new Car(audi, "A8", 320, 110000);

        CarProducer bmw = new CarProducer(R.mipmap.bmw, "BMW");
        Car bmw1 = new Car(bmw, "1er", 170, 25000);
        Car bmw3 = new Car(bmw, "3er", 230, 42000);
        Car bmwX3 = new Car(bmw, "X3", 230, 45000);
        Car bmw4 = new Car(bmw, "4er", 250, 39000);
        Car bmwM4 = new Car(bmw, "M4", 350, 60000);
        Car bmw5 = new Car(bmw, "5er", 230, 46000);

        CarProducer porsche = new CarProducer(R.mipmap.porsche, "Porsche");
        Car porsche911 = new Car(porsche, "911", 280, 45000);
        Car porscheCayman = new Car(porsche, "Cayman", 330, 52000);
        Car porscheCaymanGT4 = new Car(porsche, "Cayman GT4", 385, 86000);

        CAR_LIST.add(audiA3);
        CAR_LIST.add(audiA1);
        CAR_LIST.add(porscheCayman);
        CAR_LIST.add(audiA7);
        CAR_LIST.add(audiA8);
        CAR_LIST.add(audiA4);
        CAR_LIST.add(bmwX3);
        CAR_LIST.add(porsche911);
        CAR_LIST.add(bmw1);
        CAR_LIST.add(audiA6);
        CAR_LIST.add(audiA5);
        CAR_LIST.add(bmwM4);
        CAR_LIST.add(bmw5);
        CAR_LIST.add(porscheCaymanGT4);
        CAR_LIST.add(bmw3);
        CAR_LIST.add(bmw4);
    }
}

主activity布局

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                xmlns:tools="http://schemas.android.com/tools"
                xmlns:custom="http://schemas.android.com/apk/res-auto"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                tools:context="de.codecrafters.tableviewexample.MainActivity">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/primary"
        custom:title="@string/title_activity_main"
        custom:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" />

    <de.codecrafters.tableviewexample.SortableCarTableView
        android:id="@+id/tableView"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@id/toolbar"
        custom:columnCount="4"
        custom:headerElevation="10"
        custom:headerColor="@color/primary" />

</RelativeLayout>

SortableCarTableView

public class SortableCarTableView extends SortableTableView<Car> {

    //构造函数
    public SortableCarTableView(Context context) {
        this(context, null);
    }
    //构造函数
    public SortableCarTableView(Context context, AttributeSet attributes) {
        this(context, attributes, 0);
    }
    //构造函数
    public SortableCarTableView(Context context, AttributeSet attributes, int styleAttributes) {
        super(context, attributes, styleAttributes);

        //首行菜单初始化,public SimpleTableHeaderAdapter(Context context, String... headers)
        SimpleTableHeaderAdapter simpleTableHeaderAdapter = new SimpleTableHeaderAdapter(context, "Hersteller", "Bezeichung", "Leistung", "Preis");

 //设置字体颜色
                     simpleTableHeaderAdapter.setTextColor(context.getResources().getColor(R.color.table_header_text));
        setHeaderAdapter(simpleTableHeaderAdapter);
        //每一个item颜色差异化的操作
        int rowColorEven = context.getResources().getColor(R.color.table_data_row_even);
        int rowColorOdd = context.getResources().getColor(R.color.table_data_row_odd);
        setDataRowColoriser(TableDataRowColorizers.alternatingRows(rowColorEven, rowColorOdd));
        setHeaderSortStateViewProvider(SortStateViewProviders.brightArrows());
        //每一列在菜单的权重
        setColumnWeight(0, 2);
        setColumnWeight(1, 3);
        setColumnWeight(2, 3);
        setColumnWeight(3, 2);
        //每一列的点击业务逻辑 public void setColumnComparator(int columnIndex, Comparator<T> columnComparator) ，所以之后需要创建一个class来实现具体的业务逻辑
        setColumnComparator(0, CarComparators.getCarProducerComparator());
        setColumnComparator(1, CarComparators.getCarNameComparator());
        setColumnComparator(2, CarComparators.getCarPowerComparator());
        setColumnComparator(3, CarComparators.getCarPriceComparator());
    }

}

适配器CarTableDataAdapter

public class CarTableDataAdapter extends TableDataAdapter<Car> {
    //字体大小
    private static final int TEXT_SIZE = 14;
    //格式刷
    private static final NumberFormat PRICE_FORMATTER = NumberFormat.getNumberInstance();

    public CarTableDataAdapter(Context context, List<Car> data) {
        super(context, data);
    }

    @Override
    public View getCellView(int rowIndex, int columnIndex, ViewGroup parentView) {
        //获取每一行的对象
        Car car = getRowData(rowIndex);
        View renderedView = null;
        //获取列的具体位置,参考XLS,CSV的理解，每一行的样式都可以不同，都可以自定义
        switch (columnIndex) {
            case 0:
                renderedView = renderProducerLogo(car, parentView);
                break;
            case 1:
                renderedView = renderCatName(car);
                break;
            case 2:
                renderedView = renderPower(car, parentView);
                break;
            case 3:
                renderedView = renderPrice(car);
                break;
        }

        return renderedView;
    }

    private View renderPrice(Car car) {
        String priceString = PRICE_FORMATTER.format(car.getPrice()) + " €";

        TextView textView = new TextView(getContext());
        textView.setText(priceString);
        textView.setPadding(20, 10, 20, 10);
        textView.setTextSize(TEXT_SIZE);

        if (car.getPrice() < 50000) {
            textView.setTextColor(0xFF2E7D32);
        } else if (car.getPrice() > 100000) {
            textView.setTextColor(0xFFC62828);
        }

        return textView;
    }

    private View renderPower(Car car, ViewGroup parentView) {
        View view = getLayoutInflater().inflate(R.layout.table_cell_power, parentView, false);
        TextView kwView = (TextView) view.findViewById(R.id.kw_view);
        TextView psView = (TextView) view.findViewById(R.id.ps_view);

        kwView.setText(car.getKw() + " kW");
        psView.setText(car.getPs() + " PS");

        return view;
    }

    private View renderCatName(Car car) {
        return renderString(car.getName());
    }

    private View renderProducerLogo(Car car, ViewGroup parentView) {
        View view = getLayoutInflater().inflate(R.layout.table_cell_image, parentView, false);
        ImageView imageView = (ImageView) view.findViewById(R.id.imageView);
        imageView.setImageResource(car.getProducer().getLogo());
        return view;
    }

    private View renderString(String value) {
        TextView textView = new TextView(getContext());
        textView.setText(value);
        textView.setPadding(20, 10, 20, 10);
        textView.setTextSize(TEXT_SIZE);
        return textView;
    }

}

排序用CarComparators

每一列可实现的业务逻辑在此编写，但是你也可以不变写这部分，根据你的具体业务需要

public class CarComparators {

    public static Comparator<Car> getCarProducerComparator() {
        return new CarProducerComparator();
    }

    public static Comparator<Car> getCarPowerComparator() {
        return new CarPowerComparator();
    }

    public static Comparator<Car> getCarNameComparator() {
        return new CarNameComparator();
    }

    public static Comparator<Car> getCarPriceComparator() {
        return new CarPriceComparator();
    }

    private static class CarProducerComparator implements Comparator<Car> {

        @Override
        public int compare(Car car1, Car car2) {
            return car1.getProducer().getName().compareTo(car2.getProducer().getName());
        }
    }

    private static class CarPowerComparator implements Comparator<Car> {

        @Override
        public int compare(Car car1, Car car2) {
            return car1.getPs() - car2.getPs();
        }
    }

    private static class CarNameComparator implements Comparator<Car> {

        @Override
        public int compare(Car car1, Car car2) {
            return car1.getName().compareTo(car2.getName());
        }
    }

    private static class CarPriceComparator implements Comparator<Car> {

        @Override
        public int compare(Car car1, Car car2) {
            if (car1.getPrice() < car2.getPrice()) return -1;
            if (car1.getPrice() > car2.getPrice()) return 1;
            return 0;
        }
    }
}
