更改文字颜色

Question

我有一个白色的背景,但有这个布局,我被阻止,因为文字颜色也是白色,我找不到一个解决方案让它变红所以我可以设置我的白色背景,任何帮助请(因为你可以看到我被迫使用红色背景她所以我可以看到白色文本).

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);


    /*
    listItems.add(userName);
    adapter.notifyDataSetChanged();
    getListView().setItemChecked(listItems.size() - 1, false);*/


}

public void deleteItems(View v) {
    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();
    initializeListItems();
}

private void initializeListItems() {
    adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_multiple_choice, listItems);
    setListAdapter(adapter);
    ListView lv = getListView();
    lv.setCacheColorHint(Color.rgb(0, 0, 0));
    lv.setBackgroundColor(Color.rgb(178, 34, 34));


    for (int i = 0; i < lv.getCount(); i++) {
        lv.setItemChecked(i, false);
    }
}

Answer 1

最好的技巧是从中复制内容布局文件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);

编辑将此文件另存为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:backdround="#FFFFFF" //white background
    android:textColor="#000000" //black color text
/>

Answer 2

android:textColor="@android:color/white"
