android - 如何在android中重用布局但同时使用多个ID？

Question

本站介绍

<include layout="@layout/titlebar"/>

重用布局，所以我可能会这样编码，问题是，

<include layout="@layout/titlebar"
 android:id="@+id/bar_1"/>

<include layout="@layout/titlebar"
 android:id="@+id/bar_2"/>

如果标题栏是线性布局，并且我想获取标题栏内的 TextView ，我如何区分第 1 栏和第 2 栏？谢谢

Answer 1

尝试:

// Get root View id from that include link
View yourLayout1 = findViewById(R.id.bar1); 
View yourLayout2 = findViewById(R.id.bar2); 

// Get text view contained inside the include file
TextView yourTextView1 = (TextView)(yourLayout1.findViewById( R.id.yourInnerTextview )); 
TextView yourTextView2 = (TextView)(yourLayout2.findViewById( R.id.yourInnerTextview ));

P.S:我没有测试过，但逻辑上听起来不错。所以让我知道它是否有效。
