Question

我正在填充文件中的ListView。 ListvVew包含复选框。现在我想在复选框点击上更改单个项目文本的颜色和字体。相反，我只能突出显示单个项目行（蓝色）。我错过了什么？

main.xml

    <RelativeLayout
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:tools="http://schemas.android.com/tools"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:background="#F3E2A9">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="390dp"
        android:id="@+id/linearLayoutlist"
       android:orientation="vertical"
      >

    <ListView
        android:id="@android:id/list"
        android:layout_height="match_parent"
        android:layout_width="match_parent"
        android:choiceMode="multipleChoice"

        android:drawSelectorOnTop="false"
        android:listSelector="@drawable/listviewcolor"

        >
    </ListView>
    </LinearLayout>
    </RelativeLayout>

listviewcolor.xml

    <!-- Selected -->
<item
    android:state_focused="true"
    android:state_pressed="false"
    android:drawable="@color/red" />

<!-- Pressed -->
<item
    android:state_pressed="true"
    android:drawable="@color/blue" />

  <!-- Default -->
  <item android:drawable="@color/lightyellow" />

color.xml

<color name="blue">#ff3a8dcb</color>    
<color name="red">#FF0000</color>
<color name="lightyellow">#F3E2A9</color>

main_activity

    List arrlist=new ArrayList();  
    ArrayAdapter<String> adapter2;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    listView = getListView();
    listView.setChoiceMode(listView.CHOICE_MODE_MULTIPLE);
    listView.setTextFilterEnabled(true);

    adapter2 = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_multiple_choice, android.R.id.text1, arrlist);  //arrlist is an ArrayList
                                                                                                                         //whose value is taken from a file
    listView.setAdapter(adapter2);
        listView.setOnTouchListener(touchListener);
        listView.setOnScrollListener(touchListener.makeScrollListener());
    }

Answer 1

您可以TextColor TextFont

以编程方式更改Checkbox和onCheckedChangeListener()尺寸

 tx.setTextSize(TypedValue.COMPLEX_UNIT_SP,30);
 tx.setTextColor(Color.WHITE);

Answer 2

请显示列表项目布局，其中添加了复选框和文本视图，并在适配器中动态更改文本颜色和字体在Checkbox onCheckedChangeListener（）上，如下所示：

   final Typeface tvFont = Typeface.createFromAsset(assetManager, "OPTIMA.TTF");
    tv.setTypeface(tvFont);
    tv.setTextColor(Color.BLACK);

更改Listview中选中项目的文本颜色
