我有一个白色的背景，但这个布局我被阻止了，因为文本颜色也是白色的，我找不到一个解决方案使它变成红色，所以我可以设置我的白色背景，请任何帮助（如你所见，我被迫使用红色背景她，所以我可以看到白色文字）。
public class QueueListActivity extends ListActivity {
// LIST OF ARRAY STRINGS WHICH WILL SERVE AS LIST ITEMS
ArrayList<String> listItems = new ArrayList<String>();
String newtext;
String listFiles;
// DEFINING STRING ADAPTER WHICH WILL HANDLE DATA OF LISTVIEW
ArrayAdapter<String> adapter;
// RECORDING HOW MUCH TIMES BUTTON WAS CLICKED
int clickCounter = 0;
ArrayList<String> selectedItems = new ArrayList<String>();
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
setContentView(R.layout.queuelistactivity);
Bundle extras1 = getIntent().getExtras();
listFiles=GetFiles();
StringTokenizer tokonizer1 = new StringTokenizer(listFiles,";");
while(tokonizer1.hasMoreElements()){
Log.i("verif","0");
listItems.add(tokonizer1.nextToken());}
initializeListItems();
if (extras1 != null) {
newtext = extras1.getString("newitem");
listItems.add(newtext);
adapter.notifyDataSetChanged();
getListView().setItemChecked(listItems.size() - 1, false);
}
}
// METHOD WHICH WILL HANDLE DYNAMIC INSERTION
public void addItems(View v) {
Intent intent = new Intent(QueueListActivity.this, AjouterFiles.class);
QueueListActivity.this.startActivity(intent);

String toDelete = "";
SparseBooleanArray sp = getListView().getCheckedItemPositions();
for (int i = 0; i < sp.size(); i++) {
toDelete += ";" + sp.get(i);
if (sp.get(i)) {
listItems.remove(i);
}
}
adapter.notifyDataSetChanged();
Toast.makeText(getApplicationContext(), toDelete, Toast.LENGTH_LONG).show();

Best trick is you copy content layout file from android.R.layout.simple_list_item_multiple_choiceand make your own layout(my_list_view and edit the xml file and change the text color.
最好的技巧是您复制内容布局文件android.R.layout.simple_list_item_multiple_choice并制作自己的布局（my_list_view 并编辑 xml 文件并更改文本颜色。
adapter = new ArrayAdapter(this,my_list_view, listItems);
适配器 = 新 ArrayAdapter(this,my_list_view, listItems);
Edit save this file as my_list_view;
编辑保存此文件为 my_list_view;
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
android:layout_width="match_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:textAppearance="?android:attr/textAppearanceLarge"
android:gravity="center_vertical"
android:checkMark="?android:attr/listChoiceIndicatorMultiple"
android:paddingLeft="6dip"
android:paddingRight="6dip"
android:background="#FFFFFF" //white background
android:textColor="#000000" //black color text
/>

You can set it in the XML layout:
您可以在 XML 布局中设置它：
<TextView
...
...
android:textColor="#FF0000" >
</TextView>
Or programmatically:
或以编程方式：
textview.setTextColor(Color.RED);
//textview must be defined in your class

better to write custom adpter .
最好编写自定义适配器。
alternate but not good soltuon is use this layout xml inspace of android.R.layout.simple_list_item_multiple_choice
替代但不是很好的解决方案是在 android.R.layout.simple_list_item_multiple_choice 的空间中使用此布局 xml
<CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
android:layout_width="match_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:textAppearance="?android:attr/textAppearanceLarge"
android:gravity="center_vertical"
android:checkMark="?android:attr/listChoiceIndicatorMultiple"
android:paddingLeft="6dip"
android:paddingRight="6dip"
android:textColor= Color.Red //please correct the syntax
/>
This is same android.R.layout.simple_list_item_multiple_choice layout but your are now making same in your layouts with same ids to make the changes in it.
这是相同的 android.R.layout.simple_list_item_multiple_choice 布局，但您现在在布局中使用相同的 id 进行更改以进行更改。
