Setting a max width for LinearLayout
提问by Asahi
How can I set the max width of my horizontal LinearLayout? So if the contents are short (say, some text), the layout shrinks and if the contents are longer, it will not expand more than some max width value.
如何设置水平线的最大宽度LinearLayout？所以如果内容很短（比如一些文本），布局会缩小，如果内容较长，它不会扩展超过某个最大宽度值。
I prefer doing this at the XML level.
我更喜欢在 XML 级别执行此操作。

This does it - what I needed beyond what was suggested in prior answeris to add another layout (@+id/TheLayout) as a wrapper between the content and the top layout:
这样做 -除了先前答案中的建议之外，我需要的是添加另一个布局（@+id/TheLayout）作为内容和顶部布局之间的包装器：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingLeft="100dip"
android:paddingRight="100dip">
<LinearLayout android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/TheLayout"
android:layout_gravity="right">
<TextView android:id="@+id/TextView01"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:layout_weight="1"
android:text="this is my text."
android:layout_gravity="center_vertical">
</TextView>
<ImageView android:id="@+id/ImageView01"
android:layout_height="wrap_content"
android:background="@drawable/icon"
android:layout_width="fill_parent">
</ImageView>
</LinearLayout>
</LinearLayout>

@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int widthMaxSpec = MeasureSpec.makeMeasureSpec(270 /*pixels*/, MeasureSpec.AT_MOST);
super.onMeasure(widthMaxSpec, heightMeasureSpec);
}
