        textView0.setText(array[position]);
        textView0.setTextColor(R.color.red);//不可以设置
        textView1.setTextSize(20);

        textView1.setText(array[position]);
        textView1.setTextSize(20);//可以设置

row_simple_list_item_2.xml文件
[code="xml"]
<?xml version="1.0" encoding="utf-8"?>

android:layout_height="fill_parent"

<TextView android:id="@+id/simple_item_1"

    android:layout_height="fill_parent"
    android:gravity="center"
    android:layout_toRightOf="@id/simple_item_0"
    />

很简单的一个Listview，可为什么大小可以，颜色不可以？设置了颜色的那行居然不显示文字了。

Answer 1

ListView 的xml里有个cache color hint属性，你得把前景色设成透明，后面的字体颜色才能显示出来。。。
