package com.example.freez_t00;



public class MainActivity extends Activity {

private TextView recyclableTextView;

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);

    TableRow.LayoutParams wrapWrapTableRowParams = new TableRow.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
    int[] fixedColumnWidths = new int[]{20, 20,20, 20, 20};
    int[] scrollableColumnWidths = new int[]{20, 20, 20, 20, 20};
    int fixedRowHeight = 70;
    int fixedHeaderHeight = 70;
    TableRow row = new TableRow(this);
    //header (fixed vertically)
    TableLayout header=(TableLayout)findViewById(R.id.table_header);

    row.setLayoutParams(wrapWrapTableRowParams);
     row.setBackgroundColor(Color.YELLOW);
    row.addView(makeTableRowWithText("col1", fixedColumnWidths[0],fixedHeaderHeight));
    row.addView(makeTableRowWithText("col2", fixedColumnWidths[1],fixedHeaderHeight));
    row.addView(makeTableRowWithText("col3", fixedColumnWidths[2],fixedHeaderHeight));
    row.addView(makeTableRowWithText("col4", fixedColumnWidths[3],fixedHeaderHeight));
    row.addView(makeTableRowWithText("col5", fixedColumnWidths[4],fixedHeaderHeight));

    header.addView(row);

    //  TableLayout fixedColumn = (TableLayout) findViewById(R.id.fixed_column);
    //rest of the table (within a scroll view)
    TableLayout scrollablePart = (TableLayout)findViewById(R.id.scrollable_part);
    for(int i = 0; i < 10; i++) {
        row = new TableRow(this);
        row.setLayoutParams(wrapWrapTableRowParams);
        row.setGravity(Gravity.CENTER);
        row.setBackgroundColor(Color.WHITE);
        row.addView(makeTableRowWithText("value 1", scrollableColumnWidths[1], fixedRowHeight));
        row.addView(makeTableRowWithText("value 2", scrollableColumnWidths[1], fixedRowHeight));
        row.addView(makeTableRowWithText("value 3", scrollableColumnWidths[2], fixedRowHeight));
        row.addView(makeTableRowWithText("value 4", scrollableColumnWidths[3], fixedRowHeight));
        row.addView(makeTableRowWithText("value 5", scrollableColumnWidths[4], fixedRowHeight));
        scrollablePart.addView(row);
    }
}

public TextView makeTableRowWithText(String text, int widthInPercentOfScreenWidth, int fixedHeightInPixels) {

    int screenWidth = getResources().getDisplayMetrics().widthPixels;

    recyclableTextView = new TextView(MainActivity.this);
    recyclableTextView.setText(text);

    recyclableTextView.setTextColor(Color.BLACK);
    recyclableTextView.setTextSize(20);
    recyclableTextView.setGravity(Gravity.CENTER);
    recyclableTextView.setWidth(widthInPercentOfScreenWidth * screenWidth / 100);
    recyclableTextView.setHeight(fixedHeightInPixels);
    return recyclableTextView;
}

}

这可能对您有所帮助。我只是改革你的代码。
