Java – EditText resizes for no reason

Rather strange behavior is observed in the relative layout.

Here is the initial state:

Defined as:

<EditText
    android:id="@+id/bleedCount"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_toLeftOf="@+id/abrMult"
    android:layout_below="@+id/textView4"
    android:layout_marginRight="10dp"
    android:ems="10"
    android:inputType="number"
    >
    <requestFocus />
</EditText>

<TextView
    android:id="@+id/abrMult"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_toLeftOf="@+id/abrSubmit"
    android:layout_alignBaseline="@+id/abrSubmit"
    android:layout_marginRight="10dp"
    android:text="x12" />

<Button
    android:id="@+id/abrSubmit"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@+id/textView4"
    android:layout_alignParentRight="true"
    android:text="Calculate" />

On onItemSelected in the drop-down list, it’s changing like this:

abrSubmit.setText(pos == 1 ? "Calculate" : "Submit");
abrMult.setVisibility(pos == 1 ? View.VISIBLE : View.GONE);
bleedCount.setHint(pos == 1 ? "# of Meow/month" : "# of Meow/year");

Then it becomes like this:

Notice the height of EditText bleedCount on the second image. The value of bleedCount.getHeight() changed from 72 to 95, and I don’t understand what caused it.

It is related to android:ems="10" Related
When EditText changes its width, it must be split into two lines after displaying the View at x12.

>ems The size of a given font is one letter.

I don’t think you need ems.
Set EditText to single line: android:singleLine="true"
