Question

我试图通过代码将样式附加到TableLayout中的TextViews。

但是，我仍然保持白色背景，即使颜色是XML中的透明黑色，我想要的颜色也是先前设置的。

本质：

使用table_cell_bold style
其他，请使用table_cell
应用背景颜色
如果符合条件，请添加back.xml

到目前为止看起来像是什么：

活动代码

protected void onCreate(Bundle savedInstanceState) {
    ...

    //Total Cash Outs
    r = new TableRow(this);
    leader = cashMachine.getStats().getCashOutLeader();
    r.addView(getTableCell(this, getResources().getString(R.string.table_row_label7), row, 0));
    r.addView(getTableDataCell(this, "total_cash_out", 1, leader, row, 1));
    r.addView(getTableDataCell(this, "total_cash_out", 2, leader, row, 0));
    r.addView(getTableDataCell(this, "total_cash_out", 3, leader, row, 1));
    r.addView(getTableDataCell(this, "total_cash_out", 4, leader, row, 0));
    r.setLayoutParams(rowLayout);

    statsTable.addView(r);

    ....

    //No highlighting, just display
    else

    //Color I want is set here

    //Set border if condition is met

更新＃1

做了一些改变，这是我想出的。它的工作原理可能会更有效率。请注意switch语句加载适当的xml以设置为背景，以便我们显示领导者值。

新活动代码

private TextView getTableDataCell(Context context, String category, Integer player, ArrayList<Integer> leader, int row, int col){
        TextView t;
        String txt = "";

        int[][] backgroundColors = getBackgroundColors();

        ...

        if( leader.contains(player) && Integer.valueOf(txt) !=0)
            t = new TextView(new ContextThemeWrapper(context, R.style.table_cells_bold), null, 0);
        else
            t = new TextView(new ContextThemeWrapper(context, R.style.table_cells), null, 0);

        int resId = 0;

        if( leader.contains(player) && Integer.valueOf(txt) !=0){
            resId = getResources().getIdentifier("bg_"+row+"_"+col+"_leader", "drawable", getPackageName());
            t.setBackground(getResources().getDrawable(resId));
        }
        else
            t.setBackgroundColor(backgroundColors[row][col]);

        t.setText(txt);
        return t;
    }

Answer 1

似乎颜色代码u设置不正确

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" > 
<solid android:color="#cc000000" />
 <stroke android:width="1dp" android:color="#000"/> 
</shape>

Answer 2

我为4种不同的背景颜色创建了4种不同的XML文件。

使用以下方式动态获取资源ID：

resId = getResources().getIdentifier("bg_"+row+"_"+col+"_leader", "drawable", getPackageName());

使用此resId设置背景：

t.setBackground(getResources().getDrawable(resId));
