标签布局​​将不会显示选项卡图标 [英] Tab layout won't show tab icons

问题描述

所以，我终于为我的应用程序，完美的作品标签布局，但有一些缺失。我也投入了大量精力在设计图标，但我发现他们完全无法显示。我会后下面的code，以显示我如何试图做到这一点。

So I finally made a tab layout for my app that works flawlessly, but there's something missing. I also put a lot of effort in designing icons but I noticed that they're not showing at all. I'll post the code below to show how I tried to do it.

整个Java的code（这是所有withing的onCreate）：

The whole java code (this is all withing onCreate):

TabHost tabHost = getTabHost();

    //CRAFTING TAB
    TabSpec craftTabSpec = tabHost.newTabSpec("Crafting");
    craftTabSpec.setIndicator("Crafting", getResources().getDrawable(R.drawable.crafticonstate));
    Intent craftIntent = new Intent(this, Bifrost.class);
    craftTabSpec.setContent(craftIntent);

    //ADDITION INFO TAB
    TabSpec infoTabSpec = tabHost.newTabSpec("Info");
    infoTabSpec.setIndicator("Info", getResources().getDrawable(R.drawable.infoiconstate));
    Intent infoIntent = new Intent(this, Bifrostinfo.class);
    infoTabSpec.setContent(infoIntent);

    tabHost.addTab(craftTabSpec);
    tabHost.addTab(infoTabSpec);

crafticonstate XML code：

crafticonstate XML code:

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

我也尝试添加图标没有XML文件，只需像R.drawable.icon'，但这不能工作。

I also tried to add icon without the xml file, simply like 'R.drawable.icon' but that doesn't work either.

推荐答案

这是我使用的一个很好的伎俩。

This is one nice trick that I used.

不幸的是，因为TabHost是pciated德$ P $，它在某种程度上只显示在更高级别的API屏幕上的文本。有些解决方法是做到这一点：

Unfortunately since TabHost is depreciated, it somehow only show text in the screen on higher level Api. Some workaround is to do this:

   //CRAFTING TAB
    TabSpec craftTabSpec = tabHost.newTabSpec("Crafting");      
    craftTabSpec.setIndicator("",getResources().getDrawable(R.drawable.crafticonstate));
    Intent craftIntent = new Intent(this, Bifrost.class);
    craftTabSpec.setContent(craftIntent);

删除指示器（文本），强制标签加载图像。如果你还是想要的文字。你可以修改你的图像包含的文本。

Deleting the indicator(text), force the tab to load the images. if you still want the text. you can modify your image to include the text.
