不用一句java代码就可以实现指示器tabhost,indicator

原创!绝对原创  - - 

实现原理:

弄3个radioButton 一个radioGroup包起来,然后给drawableButton设置一个selector 选中和未选中的shape就好了.

光说不贴假把式,好了我贴代码了.

<RadioGroup
    android:layout_centerInParent="true"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="horizontal"
    >
        <RadioButton
            android:text="热门"
    
            style="@style/style_tab_live"
            />
        <RadioButton
            style="@style/style_tab_live"
            android:text="关注"
            />
        <RadioButton
            style="@style/style_tab_live"
            android:text="最新"
            />
    

</RadioGroup>

<style name="style_tab_live">
   <item name="android:layout_margin">10dp</item>
   <item name="android:text">热门</item>
   <item name="android:button">@null</item>
   <item name="android:textColor">@color/color_tab_selector</item>
   <item name="android:gravity">center</item>
   <item name="android:layout_width">wrap_content</item>
   <item name="android:layout_height">wrap_content</item>
   <item name="android:drawablePadding">3dp</item>
   <item name="android:drawableBottom">@drawable/selector_tab_indicator</item>

</style>

补充资料

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true" android:drawable="@drawable/shape_bg_tab_select"></item>
<item android:state_checked="true" android:drawable="@drawable/shape_bg_tab_select"></item>
<item android:state_pressed="true" android:drawable="@drawable/shape_bg_tab_select"></item>
<item android:drawable="@drawable/shape_bg_tab_no_select"></item>
</selector>

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
    <size android:height="2dp" android:width="50dp" />
    <solid android:color="@color/colorBlack"/>
</shape>

没有选中的

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
    <size android:height="2dp" android:width="50dp"/>
    <solid android:color="@color/colorTransparent"/>
</shape>

自定义的videoplayer,不用第三方实现高仿startFragmentForResult ,onFragmentForReuslt的封装

不需要xml包含头部不需要谷歌的action bar纯代码加头部到抽取的baseFragment,baseActivity，更多内容敬请期待!

最后贴上效果图:

使用方法:

RadioGroup radioGroup = (RadioGroup) findViewById(R.id.radiogroup);
radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(RadioGroup group, int checkedId) {
        View child = group.findViewById(checkedId);
        int i = group.indexOfChild(child);
        switch (i){
            case 0:
                break;
            case 1:
                break;
            case 2:
                break;
        }
        //然后做相关操作!
    }
});
((RadioButton) radioGroup.getChildAt(0)).setChecked(true);
