Android Next and Done Buttons

I am attempting to have the next and done buttons for two textviews to function normally. Text field 1 should move to text field two on next and text field 2 should close the keyboard/edit view on done. My XML is below:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.myapp.LaunchCam"
tools:ignore="MergeRootFrame" >

<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/autoCompleteTextView2"
android:layout_centerHorizontal="true"
android:layout_marginTop="20dp"
android:onClick="onCameraClick"
android:text="@string/start" />

<ImageView
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:src="@drawable/logo_inline_large" android:contentDescription="@string/logo"/>

<AutoCompleteTextView
android:id="@+id/autoCompleteTextView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="23dp"
android:ems="10"
android:lines = "1"
android:maxLines = "1"
android:singleLine = "true"
android:hint = "@string/enter_first_team_name"
android:nextFocusDown="@+id/autoCompleteTextView2"/>

<AutoCompleteTextView
android:id="@+id/autoCompleteTextView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/autoCompleteTextView1"
android:layout_below="@+id/autoCompleteTextView1"
android:layout_marginTop="19dp"
android:ems="10"
android:lines = "1"
android:maxLines = "1"
android:singleLine = "true"
android:hint = "@string/enter_second_team_name_optional_" />

</RelativeLayout>


When using either of these buttons I get the runtime error

11-05 16:28:11.506: E/View(27606): hasTransientState decremented below 0: unmatched pair of setHasTransientState calls

Answer

This can be done easily if I understood what you want, but I'm not sure : if you want to quicky move to the next textfield, Android provides imeOptions : the Enter key of the keyboard will change to an arrow to move to the next text field with android:imeOptions="actionNext", or to a "Go" button when it's the last one with android:imeOptions="actionGo" or android:imeOptions="actionDone". So you don't need to put a next button in your app. See this page of the documentation for mor information https://developer.android.com/training/keyboard-input/style.html
