更改简单ListView的文本颜色多项选择Android [英] Change text color of simple ListView Multiple choice Android

问题描述

我正在为板球开发一个应用程序.我的要求是这样的，如果我选择第1队，则必须显示可用国家/地区名称的列表，如果我选择一个国家/地区名称作为印度，则必须显示来自印度的球员列表，并且我要从中选择多个球员.我已经做了一切.但是我的问题是我正在使用android.R.layout.simple_list_item_multiple_choice选择玩家.我正在使用简单的列表视图，该列表的背景是黑色图像.我的列表视图就是这样

I am developing an app for cricket. My requirement is like this, if i select team 1 the list of available country name has to display and if i select a country name as India the list of player from India has to displayed and in that i have select a multiple players from that. I have done everything. But my problem is i am using android.R.layout.simple_list_item_multiple_choice for selecting players. I am using simple list view and the background of that list is black image. And my listview is like that

    <ListView
    android:id="@+id/list"
    android:layout_width="fill_parent"
    android:layout_height="0dp"
    android:layout_weight="8.5"
    android:cacheColorHint="#00000000" 

     />

现在问题是listview值显示为黑色.我已经有黑色背景图像.而且该值也为黑色.所以它看起来不太好.如何在不更改自定义适配器的情况下将listview值的颜色更改为白色.

Now the problem is the listview value is showing black in color. Already i have black background image. And the value also black in color. So its not looking good. How to change the color of listview values to white without changing o custom adapter.

这是我的适配器类

 adapter=new ArrayAdapter<String>(this,android.R.layout.simple_list_item_multiple_choice,playersName);
    lvview.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
    lvview.setAdapter(adapter);

推荐答案

您必须创建Custome TextView来更改所有ListView items的颜色，而不是将默认的android.R.layout.simple_list_item_multiple_choice传递给ArrayAdapter，您应该传递自定义列表项XML，它具有不同的TextColor属性.

You have to create Custome TextView to change color of all ListView items, instead of passing default android.R.layout.simple_list_item_multiple_choice to ArrayAdapter you should pass custom list item XML, which has different TextColor attribute.

例如，在文件夹布局"下创建了custom_list_item.xml:

For example, created custom_list_item.xml under folder Layout:

   <?xml version="1.0" encoding="utf-8"?>
   <CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"
       android:id="@+id/textView"
       android:layout_width="fill_parent"
       android:layout_height="?android:attr/listPreferredItemHeight"
       android:textAppearance="?android:attr/textAppearanceLarge"
       android:gravity="center_vertical"
       android:checkMark="?android:attr/listChoiceIndicatorSingle"
       android:paddingLeft="6dip"
       android:paddingRight="6dip"
       android:textColor="#FF00FF"
       />

然后将其传递给适配器，如下所示:

Then passed it to adapter like as below:

     new ArrayAdapter<String>(this, R.layout.custom_list_item, playersName);

已

这是我测试过的可以正常工作的代码.

Here is the code which is working fine i have tested.

   lv.setAdapter(new ArrayAdapter<String>(this, R.layout.custom_list_item, playersName));
    lv.setBackgroundColor(Color.BLACK);
    lv.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
    lv.setOnItemClickListener(new OnItemClickListener()
    {
        @Override
        public void onItemClick(AdapterView<?> p_arg0, View p_arg1, int p_arg2, long p_arg3)
        {
             my_sel_items = new String("Selected Items");
                SparseBooleanArray a = lv.getCheckedItemPositions();
                for (int i = 0; i < a.size(); i++) {
                    if (a.valueAt(i)) {
                        my_sel_items = my_sel_items + ","
                                + (String) lv.getAdapter().getItem(i);
                    }
                }
                Log.v("values", my_sel_items);
        }
    });

列表视图的布局

        <ListView
                      android:id="@+id/android:list"
                      android:layout_marginTop="60dip"
                      android:layout_width="fill_parent"
                      android:layout_height="fill_parent"
                      android:textColor="#000000"
                     />
