java - 安卓数据网格

Question

您好，我想构建一个 Android 应用程序来处理我的预算。我之前构建了一个预算应用程序，但它是在 WPF 中和 C# 中。在 WPF 中有一个叫做 DataGrid 的东西看起来像这样

我想知道 Android 中是否有类似的东西，可以向用户显示信息表。

谢谢。

public class MainActivity extends AppCompatActivity {

    // i used this array list for quick purpose
    // better way to use data models

    private String[][] gradingData = new String[][]{
            {"S.N", "Range", "Grading", "Description", "GP"},
            {"1", "90-100", "A+", "Outstanding", "4.0"},
            {"2", "80-90", "A", "Excellent", "3.6"},
            {"3", "70-80", "B+", "Very Good", "3.2"},
            {"4", "60-70", "B", "Good", "2.8"},
            {"5", "50-60", "C", "Average", "2.4"},
            {"6", "Below 50", "D", "Below Average", "2.0"},
    };


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        LinearLayout parentLayout = findViewById(R.id.parentLayout);
        parentLayout.addView(createTableLayout(7, 5));
    }

    private TableLayout createTableLayout(int rowCount, int columnCount) {
        // 1) Create a tableLayout and its params
        TableLayout.LayoutParams tableLayoutParams = new TableLayout.LayoutParams();
        TableLayout tableLayout = new TableLayout(this);
        //  tableLayout.setBackgroundColor(Color.BLACK);

        // 2) create tableRow params
        TableRow.LayoutParams tableRowParams = new TableRow.LayoutParams();
        tableRowParams.weight = 1;

        for (int i = 0; i < rowCount; i++) {
            // 3) create tableRow
            TableRow tableRow = new TableRow(this);
            // tableRow.setBackgroundColor(Color.BLACK);
            for (int j = 0; j < columnCount; j++) {
                // 4) create textView
                TextView textView = new TextView(this);
                textView.setGravity(Gravity.CENTER);
                textView.setPadding(10, 10, 10, 10);
                textView.setBackground(getResources().getDrawable(R.drawable.textview_border));
                textView.setText(gradingData[i][j]);
                if (i == 0) {
                    textView.setBackgroundColor(Color.parseColor("#aeaeae"));
                }
                tableRow.addView(textView, tableRowParams);
            }
            tableLayout.addView(tableRow, tableLayoutParams);
        }

        return tableLayout;
    }
