查看下面的代码片段，它适用于 android

TableLayout tbL = (TableLayout) findViewById(R.id.moreInfo_table);


tbL.addView(getRow(key, value), new TableLayout.LayoutParams
                      (TableLayout.LayoutParams.FILL_PARENT,TableLayout.LayoutParams.WRAP_CONTENT));
private TableRow getRow(String key, String value) {
    TableRow tbR = new TableRow(this);
    try {
        TextView keyTV = new TextView(this);
        keyTV.setText("Key " );
        keyTV.setTextColor(Color.WHITE);
        keyTV.setGravity(Gravity.CENTER_VERTICAL | Gravity.LEFT);
        keyTV.setTextSize(18.0F);
        TextView valueTV = new TextView(this);
        valueTV.setText("Value " );
        valueTV.setTextColor(Color.WHITE);
        valueTV.setGravity(Gravity.CENTER_VERTICAL | Gravity.LEFT);
        valueTV.setTextSize(18.0F);     
        tbR.addView(keyTV,new TableLayout.LayoutParams
                  (TableLayout.LayoutParams.WRAP_CONTENT,TableLayout.LayoutParams.WRAP_CONTENT));
        tbR.addView(valueTV,new TableLayout.LayoutParams
                  (TableLayout.LayoutParams.WRAP_CONTENT,TableLayout.LayoutParams.WRAP_CONTENT));
        } catch (Exception e) {
        e.printStackTrace();            
    }       
    return tbR;
}

问题出在哪里？？？？？？！！！

一旦尝试更改文本颜色；；

keyTV.setTextColor(Color.WHITE);

至

 keyTV.setTextColor(Color.BLUE);

可能是您的视图正在出现，但由于白色不可见。
