You can override the getView method of Array adapter and change the color:
您可以覆盖 Array 适配器的 getView 方法并更改颜色：
ArrayAdapter<String> adapter =
new ArrayAdapter<String>(getApplicationContext(),
android.R.layout.simple_list_item_1,
myList) {
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = super.getView(position, convertView, parent);
TextView text = (TextView) view.findViewById(android.R.id.text1);
if (flag == True) {
text.setTextColor(Color.BLACK);
}
return view;
}
};

You can do it directly in your custom Adapter.
您可以直接在您的自定义Adapter.
You can inflate row layout in this method and dynamically change view colors and other stuff.
您可以在此方法中扩展行布局并动态更改视图颜色和其他内容。

Create a Custom Layout, define your color in that layout.
创建自定义布局，在该布局中定义您的颜色。
Like this:
像这样：
<? xml version="1.0" encoding=" utf-8 "? >
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/tv"
android:textColor="@color/white" // Here You define your desired color
android:layout_width="fill_parent"
android:gravity="center"
android:layout_height="fill_parent"/>
Use this layout in your adapter, like this:
在您的适配器中使用此布局，如下所示：
ArrayAdapter<String> adapter = new ArrayAdapter<String>(
this, R.layout.custom_textview, info);
lv.setAdapter(adapter);
This way you don't need to use custom adapter.
这样您就不需要使用自定义适配器。
