Android 自定义操作栏选项卡

实现ActionBar选项卡的传统方法现在已被弃用。因此，我现在使用本指南实现了我的选项卡

但是，我在使用本指南设置选项卡样式时遇到问题。似乎您只能通过如下java代码设置选项卡的样式：

slidingTabLayout
        .setCustomTabColorizer(new SlidingTabLayout.TabColorizer() {
            @Override
            public int getIndicatorColor(int position) {
                return Color.RED;
            }
        });

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

<!-- STATES WHEN BUTTON IS NOT PRESSED -->

<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false"
      android:state_pressed="false"
      android:drawable="@drawable/tab_unselected" />
<item android:state_focused="false" android:state_selected="true"
      android:state_pressed="false"
      android:drawable="@drawable/tab_selected" />

<!-- Focused states (such as when focused with a d-pad or mouse hover) -->
<item android:state_focused="true" android:state_selected="false"
      android:state_pressed="false"
      android:drawable="@drawable/tab_unselected_focused" />
<item android:state_focused="true" android:state_selected="true"
      android:state_pressed="false"
      android:drawable="@drawable/tab_selected_focused" />

<!-- STATES WHEN BUTTON IS PRESSED -->

<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false"
      android:state_pressed="true"
      android:drawable="@drawable/tab_unselected_pressed" />
<item android:state_focused="false" android:state_selected="true"
    android:state_pressed="true"
    android:drawable="@drawable/tab_selected_pressed" />

<!-- Focused states (such as when focused with a d-pad or mouse hover) -->
<item android:state_focused="true" android:state_selected="false"
      android:state_pressed="true"
      android:drawable="@drawable/tab_unselected_pressed" />
<item android:state_focused="true" android:state_selected="true"
      android:state_pressed="true"
      android:drawable="@drawable/tab_selected_pressed" />
</selector>

这只会更改指示器的颜色，但我想更改选项卡在选中、取消选中和按下状态下的背景。传统的方法是更改主题并生成如下XML文件：

slidingTabLayout
        .setCustomTabColorizer(new SlidingTabLayout.TabColorizer() {
            @Override
            public int getIndicatorColor(int position) {
                return Color.RED;
            }
        });

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

<!-- STATES WHEN BUTTON IS NOT PRESSED -->

<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false"
      android:state_pressed="false"
      android:drawable="@drawable/tab_unselected" />
<item android:state_focused="false" android:state_selected="true"
      android:state_pressed="false"
      android:drawable="@drawable/tab_selected" />

<!-- Focused states (such as when focused with a d-pad or mouse hover) -->
<item android:state_focused="true" android:state_selected="false"
      android:state_pressed="false"
      android:drawable="@drawable/tab_unselected_focused" />
<item android:state_focused="true" android:state_selected="true"
      android:state_pressed="false"
      android:drawable="@drawable/tab_selected_focused" />

<!-- STATES WHEN BUTTON IS PRESSED -->

<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false"
      android:state_pressed="true"
      android:drawable="@drawable/tab_unselected_pressed" />
<item android:state_focused="false" android:state_selected="true"
    android:state_pressed="true"
    android:drawable="@drawable/tab_selected_pressed" />

<!-- Focused states (such as when focused with a d-pad or mouse hover) -->
<item android:state_focused="true" android:state_selected="false"
      android:state_pressed="true"
      android:drawable="@drawable/tab_unselected_pressed" />
<item android:state_focused="true" android:state_selected="true"
      android:state_pressed="true"
      android:drawable="@drawable/tab_selected_pressed" />
</selector>

如何使用新的制表方式而不必像这样安装第三方库？

您需要使用SlidingTabLayout类进行自定义。您能否提供有关如何使用制表符着色器的更多信息？
