I have a stand-alone EditText and a ListView. Each item in the ListView also has two EditText fields. When I touch inside the ListView EditText, the stand-alone EditText steals the focus. This makes it impossible to edit any of the ListView EditText fields.
Name steals the focus from the other TextView elements inside the ListView
Here is the activity's XML, containing the stand-alone EditText and the ListView
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="16dip"
android:orientation = "vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_marginBottom="16dip" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="16dip"
android:layout_weight="1"
android:text="#string/name"
android:textAppearance="?android:attr/textAppearanceMedium" />
<EditText
android:id="#+id/editblindschedule_name"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_weight="5"
android:ems="10"
android:inputType="text" />
</LinearLayout>
<ListView
android:id="#+id/listview_editblindschedule"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
And here is the ListView row XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="#+id/editblindschedule_round"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="2"/>
<EditText
android:id="#+id/editblindschedule_small"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="#string/small"
android:ems="4"
android:inputType="number"
android:layout_weight="4"
android:layout_marginRight="10dip"
android:text="#string/integer_zero"
android:gravity="center" />
<EditText
android:id="#+id/editblindschedule_big"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="#string/big"
android:ems="4"
android:inputType="number"
android:layout_weight="4"
android:layout_marginRight="10dip"
android:paddingRight="6dip"
android:text="#string/integer_zero"
android:gravity="center" />
<CheckBox
android:id="#+id/editblindschedule_checkbox"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:checked="true" />
</LinearLayout>
Here is the Java code
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_edit_blind_schedule);
...
adapter = new BlindAdapter(this, blindSchedule.getBlindLevels());
listView = (ListView) findViewById(R.id.listview_editblindschedule);
listView.setAdapter(adapter);
And finally, the adapter:
#Override
public View getView(int position, View convertView, ViewGroup parent)
{
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View row = inflater.inflate(R.layout.listview_editblindschedule, parent, false);
if (!creating) { // Set default values.
TextView round = (TextView) row.findViewById(R.id.editblindschedule_round);
EditText small = (EditText) row.findViewById(R.id.editblindschedule_small);
EditText big = (EditText) row.findViewById(R.id.editblindschedule_big);
round.setText("" + (position + 1));
small.setText("" + blindLevels.get(position).getSmallBlind());
big.setText("" + blindLevels.get(position).getBigBlind());
}
return row;
}
The solution that worked for me was to put android:windowSoftInputMode="adjustPan" in the activity in the manifest. This was the only change necessary for me.
I don't like it but after digging ListView code I ended up by overriding the getFocusedChild() method and returning null as all other trials of flag combinations didn't get to a satisfactory solution.
Even if android:windowSoftInputMode="adjustPan" works adjusting pan leads to too much artifacts in my layout.
Beware overriding that method may lead to other unwanted behaviours so use it and test it comprehensively in all android versions you support and may be call super instead of returning null for android versions that does not/will have this problem.

I am trying to set focus on a LinearLayout view when returning to an activity from another activity. The scenario:
I have one activity with a bunch of LinearLayout items (with stuff in them), some of which are text, others photos. Let's say the top most of 20 is a TextView and the rest are photos. When I leave this activity (to take a picture), activity goes to the top of the list where the TextView is - no matter what I do.
How do I force the focus back on the item that I was on before the new activity was triggered?
I have already tried this with no success:
[How Linear Layout get Focus?
I am currently trying to force the focus by remembering the previous view without success (though I can see the code being executed). The in my main activity:
#Override
public void onResume() {
super.onResume();
// See if we had a field with focus previously...
if (mPreviousView != null) {
if (mPreviousView.isFocusable()) {
mPreviousView.requestFocus();
}
}
}
...
#Override
protected void onPause() {
super.onPause();
mPreviousView = this.getCurrentFocus();
}
I am dynamically setting the focus in the LinearLayout:
private void initialize() {
LayoutInflater inflater = (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
inflater.inflate(R.layout.field_photo_picker, this);
// To allow focus to be returned to control after taking photo
this.setFocusableInTouchMode(true);
this.setFocusable(true);
this.setClickable(true);
And finally the XML for the LinearLayout:
<?xml version="1.0" encoding="utf-8"?>
<merge xmlns:android="http://schemas.android.com/apk/res/android">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"

make your textview and other views focusable, you made this.setFocusable(true); which doesn't make sense
Good day.
I have an android application. In my application, I have a custom listView with 5 columns that are textViews. The user can click the rows, once he does, the row layout will change, changing the last 2 textViews to EditTexts. I then register the new EditTexts onto my custom keyboard taken from this example - kindly note that I did a functional copy-paste of his example with regards to the custom keyboard class and how to make it work in the main layout. However, when I click the EditText in the row, my custom keyboard does not show up at all.
I have a global variable as such:
CustomKeyboard mCustomKeyboard;
And in my onCreate() method in the activity, I do:
mCustomKeyboard= new CustomKeyboard(this, R.id.keyboardview, R.xml.custom_keyboard);
This is my layout, I have the KeyboardView at the bottom of the Layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:paddingBottom="#dimen/activity_vertical_margin"
tools:context=".SearchResult" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<!-- A lot of views go here, enclosed in my linear layout -->
</LinearLayout>
<android.inputmethodservice.KeyboardView
android:id="#+id/keyboardview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:focusable="true"
android:focusableInTouchMode="true"
android:visibility="gone" />
</RelativeLayout>
Here is the code that changes the layout. What I do is that I take the row values from the old layout, get the new layout search_result_inflate, then set the texts of the new layout using the values I got. Kindly note the mCustomKeyboard.registerEditText(R.id.qtyInputSearchResult); line after inflating the layout:
private void changeLayout(final View view){
//get views from old layout
TextView textViewQuantity = (TextView)view.findViewById(R.id.qtyInput);
TextView textViewDiscountReq = (TextView)view.findViewById(R.id.discInput);
TextView textViewName = (TextView)view.findViewById(R.id.dialogItemName);
TextView textViewPrice = (TextView)view.findViewById(R.id.price);
TextView textViewDiscount = (TextView)view.findViewById(R.id.discount);
//store values in strings
String itemName = textViewName.getText().toString();
String itemPrice = textViewPrice.getText().toString();
String itemDiscount = textViewDiscount.getText().toString();
String itemQty = textViewQuantity.getText().toString();
String itemDisc = textViewDiscountReq.getText().toString();
//set the view to gone
textViewQuantity.setVisibility(View.GONE);
textViewDiscountReq.setVisibility(View.GONE);
textViewName.setVisibility(View.GONE);
textViewPrice.setVisibility(View.GONE);
textViewDiscount.setVisibility(View.GONE);
//get the old layout
LinearLayout ll_inflate = (LinearLayout)view.findViewById(R.id.search_result_layout);
//get the inflate/new view
View child = getLayoutInflater().inflate(R.layout.search_result_inflate, null);
//get the views in the new view, populate them
TextView newName = (TextView)child.findViewById(R.id.dialogItemName);
newName.setText(itemName);
TextView newDiscount = (TextView)child.findViewById(R.id.discount);
newDiscount.setText(itemDiscount);
TextView newPrice = (TextView)child.findViewById(R.id.price);
newPrice.setText(itemPrice);
EditText qtyInput = (EditText)child.findViewById(R.id.qtyInputSearchResult);
qtyInput.setText(itemQty);
EditText discInput = (EditText)child.findViewById(R.id.discInputSearchResult);
discInput.setText(itemDisc);
//show new layout
ll_inflate.removeAllViews();
ll_inflate.removeAllViewsInLayout();
ll_inflate.addView(child);
mCustomKeyboard.registerEditText(R.id.qtyInputSearchResult);
}
Here is my search_result_inflate.xml file:

As you can see, I have 2 editTexts and I registered qtyInputSearchResult to the custom keyboard class. However, the custom keyboard does not show up.
I also tried to use the custom keyboard class on an editText in another activity and it works just fine. Am I missing something here? I'm confused as to why the custom keyboard does not show up properly.
Any help is very much appreciated, thank you.
Got it, I placed the keyboard layout in the search_result_inflate.xml like so:
<?xml version="1.0" encoding="utf-8"?>

I did a custom Adapter for my List View which extends a basicadapter,
it was working fine until i added another row to my list_item.xml
so now when in my OnItemClickListner, on click should show the description of the item in the row under it which was hidden. that works fine except that when i click on any item it shows the row under of description and another's of item in the bottom of the list, although i only pressed on one item and when i scroll down and up again the row of the item a clicked on disappears but the other one that opened by itself stays opened. i searched and found that it might be because i dont use bindView and any List takes from 5-10 items then reuses them. if that the case how can i implement a bindVIew to my customAdapter. ataached s my on click listener and getView of my customAdapter
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// getting values from selected ListItem
if ((((LinearLayout) view.findViewById(R.id.edit)).getVisibility()) == (View.VISIBLE))
{
((LinearLayout) view.findViewById(R.id.edit)).setVisibility(View.GONE);
}else
{
((LinearLayout) view.findViewById(R.id.edit)).setVisibility(View.VISIBLE);
((EditText) view.findViewById(R.id.itemn)).setFocusable(true);
new LoadCategories().execute();
}
2nd problem: i have my description row has an editText which shows the description which is visible under the item when i press on any item. but i cant press on it to change it or edit it when it shows up.
public View getView(final int position, View convertView, ViewGroup parent) {
System.out.println("getView " + position + " " + convertView);
final ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(l, null);
holder = new ViewHolder();
holder.id = (TextView)convertView.findViewById(R.id.id);
holder.name = (TextView)convertView.findViewById(R.id.name);
holder.price = (TextView)convertView.findViewById(R.id.price);
holder.description = (TextView)convertView.findViewById(R.id.description);
holder.button = (Button) convertView.findViewById(R.id.update);
holder.btn = (Button) convertView.findViewById(R.id.order);
holder.en = (EditText)convertView.findViewById(R.id.itemn);
holder.ep = (EditText)convertView.findViewById(R.id.pri);
holder.ed = (EditText)convertView.findViewById(R.id.descript);
convertView.setTag(holder);
}
else {
holder = (ViewHolder)convertView.getTag();
}
holder.id.setText(getId(getItem(position)));
holder.name.setText(getName(getItem(position)));
holder.price.setText("£ " + getPrice(getItem(position)));
holder.description.setText(getDesc(getItem(position)));
holder.btn.setVisibility(View.GONE);
holder.en.setText((holder.name.getText()).toString());
holder.ep.setText((holder.price.getText()).toString());
holder.ed.setText((holder.description.getText()).toString());
return convertView;
}
public void clear(){
itemsList.clear();
notifyDataSetChanged();
}
}
here is my list_item.xml. Baically first tableRow shows all the info passed from an array of hashMap. 2nd row not used yet. Third TableRow takes the info from the first row and set it to the editText which then can be modified so afterwards it will be used to update the database with the corrected information. third row is hidden and is showed when an item is pressed.

although i only pressed on one item and when i scroll down and up again the row of the item a clicked on disappears but the other one that opened by itself stays opened.
You are fighting the way that ListView's recycle Views, watch Google's Turbo-Charge your UI for a detailed explanation of how this works. The solution is simple: inside your Adapter you must remember which rows have been expanded and set them accordingly in getView() or collapse every row by default.
but i cant press on it to change it or edit it when it shows up.
I noticed that you are making an EditText focusable, try changing setFocusableInTouchMode() instead. These methods are linked in subtle ways.
Addition
One observation I have is that you have some unnecessary layouts, if a layout only has one child then you can probably remove it. For instance, you can either remove the TableLayout or the RelativeLayout and you can either remove LinearLayout edit or the TableRow.
i can't repress on the item to close or hide the expandable part after i am done with it.
I don't see a specific reason why you cannot touch anything in row one or two to hide the third row again... Perhaps you should add a Button that hides / shows this row/
what i face is that the expanded part that opens when i press on an item disappears when i scroll down
I walked another user through this: Android: ListView bug
In my answer there pay attention to how I use expanded to track whether each row should show or hide the extra layout, and notice how expanded is controlled in mName.
So I've been trying to figure out layouts and using the layout inflater, but I'm running into some issues. I have two relative xml layout files, the one xml file has two textViews, an editText field, and a spinner object:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/firstLayout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:id="#+id/goalNameView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="5dip"
android:text="#string/goalName" />
<EditText
android:id="#+id/goal_name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_toRightOf="#+id/goalNameView"
android:hint="#string/editText"
android:ems="10" >
<requestFocus />
</EditText>
<TextView
android:id="#+id/goalTasksView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="#+id/goal_tasks"
android:layout_alignBottom="#+id/goal_tasks"
android:layout_alignLeft="#+id/goalNameView"
android:text="#string/goalTasks" />
<Spinner
android:id="#+id/goal_tasks"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/goalTasksView"
android:layout_marginTop="51dp" />
</RelativeLayout>
the other xml file has one textView and one editText field:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/tView"
>
<EditText
android:id="#+id/taskNameField"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/taskNameView"
android:ems="10"
android:hint="#string/editText" />
<TextView
android:id="#+id/taskNameView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="#+id/taskNameField"
android:layout_alignBottom="#+id/taskNameField"
android:layout_alignParentLeft="true"
android:text="#string/taskName"
/>
</RelativeLayout>
I'm trying to patch the two layouts together with a third xml file (main.xml):
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="vertical"
android:id="#+id/theMain"
>
<include android:id="#id/mainLayout" layout="#layout/activity_goal_keeper" />
</LinearLayout>
The way I'm looking to have the layout work is to display the first layout (#id/firstLayout) and then the second layout (#id/tView) directly beneath it. I've read that I need to implement the layouts on a LinearLayout to achieve this which is why I have the third layout (#id/theMain).
As you can see I have an include statement for #id/firstLayout, but I don't have an include statement for #id/tView because I'm trying to inflate multiple versions of #id/tView via my main activity:
public class GoalKeeperActivity extends Activity implements AdapterView.OnItemSelectedListener {
public Integer[] items= {1,2,3,4,5,6,7,8};
#Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
//setContentView(R.layout.activity_goal_keeper);
setContentView(R.layout.main);
Spinner numOfTasks=(Spinner) findViewById(R.id.goal_tasks);
numOfTasks.setOnItemSelectedListener(this);
ArrayAdapter<Integer> aa = new ArrayAdapter<Integer>(this, android.R.layout.simple_spinner_item, items);
aa.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
numOfTasks.setAdapter(aa);
ViewGroup item = (ViewGroup) findViewById(R.id.theMain);
for(int i=0; i<3;i++)
{
View child = getLayoutInflater().inflate(R.layout.tasks_view, item, false);
child.setId(i);
item.addView(child);
}
My problem is that #firstLayout displays properly, but #tView doesn't show up at all. Can someone please explain what I'm missing?
Thanks in advance.
I figured it out, it was simply an issue of setting the "android:layout_height" attribute equal to wrap_content on the #id/tView xml file. Silly little mistakes...
I have an ExpandableListView. The xml for the Child rows looks like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/list_item_child"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<EditText
android:id="#+id/number_input_1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:ems="10"
android:gravity="right"
android:inputType="numberDecimal" >
<requestFocus />
</EditText>
<Spinner
android:id="#+id/spinner_1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1" />
</LinearLayout>
<TextView
android:id="#+id/textView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:text="#string/temp_txt" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<EditText
android:id="#+id/number_input_2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:ems="10"
android:gravity="right"
android:inputType="numberDecimal" />
<Spinner
android:id="#+id/spinner_2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1" />
</LinearLayout>
</LinearLayout>
Basically, my getChildView looks like this:
public View getChildView(int i, int i1, boolean b, View view, ViewGroup viewGroup) {
if (view == null) {
view = inflater.inflate(R.layout.list_item_child, viewGroup, false);
}
Spinner spinner = (Spinner) view.findViewById(R.id.spinner_1);
spinner.setAdapter(mUnitsCA);
spinner.setSelection(14); // 14 is a test
spinner.setOnItemSelectedListener(mSpinnerListener);
return view;
}
This should ensure that item number 14 in spinner_1 is selected every time. Some of the time this works, but often it selects the first item in the spinner instead. I can't work out where this is happening. Any ideas?
One recommendation I found was to change setSelection() to the following:
spinner.setSelection(14, true);
Edit: (Building upon my answer for future seekers)
The documentation seems to be very vague on this, simply stating the following:
setSelection(int position, boolean animate);
//Jump directly to a specific item in the adapter data.
In my research it seems that many have had the same issues and from what I can tell declaring the animation boolean seems to be necessary more often then not, whether it be true or false. Maybe only custom animations or declared animation's require a boolean value of true in order to animate but not having an animation will accept either true or false...
