我添加自定义IMG的头冠军，但无论我做什么，我仍然对IMG的每一面小的差距（也显示在此question)

下面是我的strings.xml文件中的XML

 ＆LT;？XML版本=1.0编码=UTF-8＆GT？;＆LT;资源＆GT;    ＆LT;字符串名称=你好＆GT;＆LT; /串＆GT;    ＆LT;字符串名称=APP_NAME＆GT;＆LT; /串＆GT;    ＆LT;样式名称=LargeTitleTheme父=机器人：Theme.Light＆GT;        ＆LT;项目名称=机器人：windowTitleSize＆GT; 44dip＆LT; /项目＆GT;    ＆LT; /风格＆GT;＆LT; /资源＆GT; 

下面是我的活动code（忽略斜率 - 绝望的编码在这一点上）

 的ViewGroup decorView =（ViewGroup中）this.getWindow（）getDecorView（）;    的LinearLayout根=（的LinearLayout）decorView.getChildAt（0）;    的FrameLayout titleContainer =（的FrameLayout）root.getChildAt（0）;    TextView的标题=（TextView中）titleContainer.getChildAt（0）;    title.setGravity（Gravity.CENTER）;    可绘制可绘制= getResources（）getDrawable（R.drawable.nav）。    drawable.setBounds（0,0,0,0）;    title.setBackgroundDrawable（绘制）;    （0,0,0,0）title.setPadding;    title.setIncludeFontPadding（假）; 

解决方案

原来我不得不修改标题容器本身的背景色：）

 私人无效setNavigationAndTitle（）{        的setTitle（随机标题）;        ViewGroup中decorView =（ViewGroup中）this.getWindow（）getDecorView（）。        的LinearLayout根=（的LinearLayout）decorView.getChildAt（0）;        的FrameLayout titleContainer =（的FrameLayout）root.getChildAt（0）;        titleContainer.setBackgroundColor（Color.BLUE）;        TextView的标题=（TextView中）titleContainer.getChildAt（0）;        title.setTextSize（20）;        title.setGravity（Gravity.CENTER）;        title.setBackgroundColor（Color.BLUE）;} 

I'm adding a custom img to the header title but no matter what I do I still have a small gap on each side of the img (also shown in this question)

Here is the xml in my strings.xml file

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <string name="hello"></string>
    <string name="app_name"></string>
    <style name="LargeTitleTheme" parent="android:Theme.Light">
        <item name="android:windowTitleSize">44dip</item>
    </style>
</resources>

Here is the code in my activity (ignore the slop - desperate coding at this point)

ViewGroup decorView = (ViewGroup) this.getWindow().getDecorView();
    LinearLayout root = (LinearLayout) decorView.getChildAt(0);
    FrameLayout titleContainer = (FrameLayout) root.getChildAt(0);
    TextView title = (TextView) titleContainer.getChildAt(0);
    title.setGravity(Gravity.CENTER);
    Drawable drawable = getResources().getDrawable(R.drawable.nav);
    drawable.setBounds(0,0,0,0);
    title.setBackgroundDrawable(drawable);
    title.setPadding(0,0,0,0);
    title.setIncludeFontPadding(false);

解决方案

It turns out I had to modify the background color of the title container itself :)

private void setNavigationAndTitle() {
        setTitle("Random Title");
        ViewGroup decorView = (ViewGroup) this.getWindow().getDecorView();
        LinearLayout root = (LinearLayout) decorView.getChildAt(0);
        FrameLayout titleContainer = (FrameLayout) root.getChildAt(0);
        titleContainer.setBackgroundColor(Color.BLUE);
        TextView title = (TextView) titleContainer.getChildAt(0);
        title.setTextSize(20);
        title.setGravity(Gravity.CENTER);
        title.setBackgroundColor(Color.BLUE);
}
