Android系统。如何在单击时更改ListView文本颜色？

I change the color with this code, but the color changes only when i quit from the application and run it again. How can I resolve to change immediately the color?

我使用此代码更改颜色，但只有当我退出应用程序并再次运行时颜色才会更改。如何解决立即更改颜色？

adapter2 = new ArrayAdapter<String>(getApplicationContext(),
            android.R.layout.simple_list_item_1, list) {
        @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);
            text.setTextColor(Color.parseColor(color));
            return view;
        }
    };

2 个解决方案

#1

Create res/color/button_text.xml

创建res / color / button_text.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true"
      android:color="#ffff0000"/> <!-- pressed -->
<item android:state_focused="true"
      android:color="#ff0000ff"/> <!-- focused -->
<item android:color="#ff000000"/> <!-- default -->
</selector>

This layout XML will apply the color list to a View:

此布局XML将颜色列表应用于视图：

<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="TextView"
android:textColor="@color/button_text" />

And if you want to apply State Color Dynamically then

如果你想动态应用状态颜色那么

ColorStateList myColorStateList = new ColorStateList(
                    new int[][]{
                            new int[]{android.R.attr.state_pressed}, //1
                            new int[]{-android.R.attr.state_focused}, //2
                            new int[]{android.R.attr.state_selected, android.R.attr.state_pressed} //3
                    },
                    new int[] {
                        Color.RED, //1
                        Color.WHITE, //2
                        Color.BLUE //3
                    }
                );
            title_txt.setTextColor(myColorStateList);

Put this file in res/color folder as textselector_list.xml

将此文件作为textselector_list.xml放在res / color文件夹中

<?xml version="1.0" encoding="utf-8"?>

<item android:state_pressed="true" android:color="#FFFFFFFF"/>
<!-- pressed -->
<item android:state_focused="true" android:color="#FFFFFFFF"/>
<!-- focused -->
<item android:state_selected="true" android:color="#FFFFFFFF"/>
<!-- selected -->
<item android:color="#FF888888"/>
<!-- default -->

And set this as android:textColor="@color/textselector_list" to the listView item i.e. your TextView or Button.

并将其设置为android：textColor =“@ color / textselector_list”到listView项，即TextView或Button。
