在 com.android.support:design:23.1.0 中更改左侧、顶部、右侧或底部的 TabLayout 图标 [英] Changing TabLayout icons on left, top, right or bottom in com.android.support:design:23.1.0
问题描述
我对 android 开发还很陌生.所以请耐心等待.
I'm pretty new to android development. So bear with me.
我已经尝试将 com.android.support:design:23.1.0 中的图标和文本在同一行中对齐一天.
I've been trying to align the icon and text in same line in com.android.support:design:23.1.0 for a day.
显然在 com.android.support:design:23.1.0 中,他们已将默认图标位置更改为顶部,并将文本更改为底部.
Apparently in com.android.support:design:23.1.0 they've changed the default icon position to top and text on the bottom.
以前在 com.android.support:design:23.0.1 中默认是左侧的图标和与图标在同一行的文本
Previously in com.android.support:design:23.0.1 the default was the icon on left and text in same line as the icon
所以这里有一个简单的方法来解决它(尽管它可能有缺点,idk tbh):
So here's an easy way to solve it (though it might have drawbacks, idk tbh):
change the version in your app's build.gradle. ex: 23.1.0 to 23.0.1 and build.
还有一个更好的方法来做到这一点(这样你也可以在左、右、上、下对齐图标):
And there's a better way to do it (this way you can also align icons on left,right,top,bottom):
- 在res/layout 中创建一个custom_tab.xml
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/tab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAlignment="center"/>
2.在你的活动java
2. in your activity java
TextView newTab = (TextView) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
newTab.setText("tab1"); //tab label txt
newTab.setCompoundDrawablesWithIntrinsicBounds(your_drawable_icon_here, 0, 0, 0);
tabLayout.getTabAt(tab_index_here_).setCustomView(newTab);
到目前为止,我已经使图标出现在任何一侧,如下所示:
So far I've achieved to make icons appear on any side like this:
PS:setCompoundDrawablesWithIntrinsicBounds 函数参数是 4 个侧面图标,如下所示:
PS: setCompoundDrawablesWithIntrinsicBounds function arguments are 4 side icons like this:
setCompoundDrawablesWithIntrinsicBounds(leftDrawable, topDrawable, rightDrawable, bottomDrawable)
推荐答案
感谢 Atu 的这个好提示!
Thank you Atu for this good tip!
就我而言,我必须将线性布局添加到中心 tablayout 标题.我还添加了一些空格字符来获得图标和文本之间的边距.
In my case, I have to add a linear layout to center tablayout title. I have also added some space characters to get margin between the icon and the text.
custom_tab.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center">
<TextView
android:id="@+id/tabContent"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:textAlignment="center"
android:textColor="@android:color/white"
android:gravity="center"/>
</LinearLayout>
初始化代码:
LinearLayout tabLinearLayout = (LinearLayout) LayoutInflater.from(this).inflate(R.layout.custom_tab, null);
TextView tabContent = (TextView) tabLinearLayout.findViewById(R.id.tabContent);
tabContent.setText(" "+getApplicationContext().getResources().getString(tabTitles[i]));
tabContent.setCompoundDrawablesWithIntrinsicBounds(tabIcons[i], 0, 0, 0);
mTabLayout.getTabAt(i).setCustomView(tabContent);
