When developing Android applications, it’s common to encounter issues where an EditText element automatically gains focus when an activity starts. This can be undesirable, especially if you don’t want the virtual keyboard to appear immediately. Below, we provide a comprehensive guide to prevent EditText from gaining focus when an activity starts.
Solution 1: Modify Parent Layout Attributes
The most effective and straightforward solution involves modifying the parent layout attributes. By setting android:focusableInTouchMode="true" and android:focusable="true" to the parent layout, you can prevent the EditText from gaining focus on startup.
<LinearLayout
android:focusable="true"
android:focusableInTouchMode="true"
android:layout_width="0px"
android:layout_height="0px" />
<AutoCompleteTextView
android:id="@+id/autotext"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:nextFocusUp="@id/autotext"
android:nextFocusLeft="@id/autotext" />
Solution 2: Use descendantFocusability in Parent Layout
Another effective method is to set the descendantFocusability attribute in your parent layout. This ensures that the parent layout gains focus before its descendants.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/mainLayout"
android:descendantFocusability="beforeDescendants"
android:focusableInTouchMode="true" >
</RelativeLayout>
You can also programmatically remove focus from child views at runtime:
findViewById(R.id.mainLayout).requestFocus();
Solution 3: Adjust Activity’s Soft Input Mode
If the issue is related to the virtual keyboard opening upon focus, you can adjust the windowSoftInputMode in your AndroidManifest.xml file.
<activity android:name=".MyActivity"
android:windowSoftInputMode="stateHidden" />
Solution 4: Remove requestFocus from EditText
Ensure that the <requestFocus /> tag is removed from your EditText element in the XML layout.
<EditText
android:id="@+id/emailField"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:inputType="textEmailAddress" />
