tabhost /图标的TabBar不显示 [英] tabhost /tabbar icons not showing

问题描述

我的标签栏图标不会显示出来

my tab bar icon wont show up

TabHost tabHost = getTabHost();

TabSpec barcodeInsertSpec = tabHost.newTabSpec("Barcode Insert");
barcodeInsertSpec.setIndicator("Barcode Insert", getResources().getDrawable(R.drawable.home2));
barcodeInsertSpec.setContent(new Intent(getBaseContext(), BarcodeInsertActivity.class));

tabHost.addTab(barcodeInsertSpec);

绘制/ home2.xml

drawable/home2.xml

<?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
        <!-- When not selected, use that-->
        <item android:drawable="@drawable/home22" />
    </selector>

和把画面在不同尺寸（48×48，32×32，24×24）绘制，华电国际三个文件夹
，绘制-LDPI，...为png格式

and put picture in three folders in different sizes (48x48, 32x32, 24x24) drawable-hdpi , drawable-ldpi, ... as .png

像绘制，华电国际/ home22.png

like drawable-hdpi/home22.png

推荐答案

试试这个code

<selector xmlns:android="http://schemas.android.com/apk/res/android" >
     <item  android:state_focused="true"
            android:state_pressed="true"
            android:drawable="@drawable/button0_click"></item>
    <item   android:state_focused="true"
            android:state_pressed="false"
            android:drawable="@drawable/button0_click"></item>
    <item
            android:state_focused="false"
            android:state_pressed="true"
            android:drawable="@drawable/button0_click" />
     <item 
            android:drawable="@drawable/button0"></item>

</selector>
