How to use android:maxWidth?
android, width
Solution
I want to set a maximum width of an edit box.
In your example:
<EditText
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:ems="10" />
The `layout_width` and `ems` attributes are trying to set the same value. Android seems to choose the larger `fill_parent` value and ignores the other. And when you use this:
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ems="10"
android:maxWidth="50dp"
android:minWidth="50dp" />
Here `ems` and `maxWidth` are trying to set the same value, again the greater value is used. So depending on what you actually want you can use:
<EditText
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ems="10" />
or replace `android:ems="10"` with `android:maxWidth="50dp"` if you prefer to work with dp.
Lastly your LinearLayout only has one child, the EditText. Typically when this happens you can remove the LinearLayout tags and use the EditText by itself.
Problem
I want to set a maximum width of an edit box. So I created this small layout: ``` <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:maxWidth="150dp" > <EditText android:layout_width="fill_parent" android:layout_height="wrap_content" android:ems="10" /> </LinearLayout> ``` But it doesn't work, the box could be more than 150 dp anyway. `android:maxWidth="150dp"` in the `EditText` will give the same result. I have read ( maxWidth doesn't work with fill_parent ) that setting both max- and min width to the same size should solve it: ``` <EditText android:layout_width="wrap_content" android:layout_height="wrap_content" android:ems="10" android:maxWidth="50dp" android:minWidth="50dp" /> ``` But it doesn't. I have found a solution to my problem here here: Setting a maximum width on a ViewGroup And this works great. But I guess the `maxWidth` attribute is here for I reason. How should it be used? Or is there any documentation on this? I have spend hours on this problem, and still doesn't understand how to use this simple attribute.
