I already read tons of similar questions, but I found no solution that fixed my problem, so please do not mark this as duplicate.
I have a ListFragment with a FrameLayout containing a ListView, populated through a custom ArrayListAdapter.
Each row of the list has three elements:
Checkbox, EditText and ImageButton.
My problem is that when I tap on an EditText to change the string it contains the keyboard shows up, but the focus immediately goes away and I'm not able to write.
Please note that I already have added to my Activity in the manifest file
android:windowSoftInputMode="adjustResize"
even the
android:descendantFocusability="afterDescendants"
android:descendantFocusability="beforeDescendants"
doesn't solve the problem.
Here is my XML code:
row_item.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<CheckBox
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/item_checkbox"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
/>
<EditText
android:id="#+id/item_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:minHeight="60px"
android:text="Test text"
android:singleLine="true"
android:layout_toRightOf="#id/item_checkbox"
android:layout_centerVertical="true"
android:layout_toLeftOf="#+id/item_important"
android:layout_toStartOf="#+id/item_important" />
<ImageButton
android:id="#+id/item_important"
android:layout_width="20dip"
android:layout_height="20dip"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="10dp"
android:visibility="visible"
android:layout_marginLeft="10dp" />
</RelativeLayout>
fragment_list.xml
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="8dp"
android:paddingRight="8dp"
>
<ListView android:id="#id/android:list"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</FrameLayout>
It would be great if you could suggest me some resource where to understand how focusability works in this case.
Thank you
UPDATE
I found out the problem is created by the keyboard showing up: I guess the view recycling is the reason why the EditText loses focus.
I solved my issue using the new RecyclerView class. It seems that was a problem of the ListView
Try this code
row_item.xml
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:focusable="false"/>
<EditText
android:id="#+id/item_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:layout_toLeftOf="#+id/item_important"
android:layout_toRightOf="#id/item_checkbox"

Did you set android:focusable="true" and android:focusableInTouchMode="true" on your EditText?
Also the android:windowSoftInputMode="adjustPan" in your AndroiManifest file.

This is most likely a problem with the linear layout for each item. The orientation is horizontal, which lays each view one after the other horizontally. The problem is that the text view for the animal type has a width of fill_parent leaving no space for the breed view. If you change it to wrap_content it'll probably work for some of the cases, but might not work with everything.
In any case I think this is a problem with the views' positions and sizes. Try and move them around. Perhaps even a simple change would be placing them vertically:
<?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="wrap_content"
android:orientation="horizontal">
<ImageView
android:id="#+id/imageView"
android:layout_width="50dp"
android:layout_height="50dp"
android:padding="5dp" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:id="#+id/textView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Demo"
android:textColor="#000" />
<TextView
android:id="#+id/breed"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="Breed"
android:textColor="#000" />
</LinearLayout>
</LinearLayout>
There's perhaps a more efficient way of doing this, but this is just an example. The inner linear layout places one text view on to of the other.
PS: your getCount method is not really doing anything. You can remove it.
replace your layout with my code your issue will resolve.

I have gone through this & this SO questions but unable to figure out why the first item of my list view is not visible. I have checked the size of arraylist and it's correct.
if there is 2 items then it shows only 1.
if there is 1 item then it shows 0.

Change the ListView attribute layout_width and layout_height to Fill_Parent
it worked for me.
I was having the same issue because my ListView layout_width and layout_height was "match_constraint" and the toolbar was overlapping the first item. Just adjust the height of the ListView. It works for me.
I search a lot for an answer and didn't find one that suit me.
I found out that when I set my layout_heigh to 500dp -> all the item shown, but when it has normal size (layout_heigh=wrap_content) then only the first item is shown.
this is my code:
activity_main.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"
android:orientation="vertical">
<Button
android:layout_width="match_parent"
android:layout_height="50dp"
android:text="Add Task"
android:onClick="addTask" />
<ListView android:id="#+id/myListView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawSelectorOnTop="false"/>
</LinearLayout>
xml_item.xml: this is for one item to duplicate in the listView
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:descendantFocusability="blocksDescendants">
<TextView
android:layout_width="100dp"
android:layout_height="50dp"
android:id="#+id/itemText"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:padding="15dp"
android:textSize="20sp" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/doneBtn"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:layout_marginRight="5dp"
android:text="Done" />
</RelativeLayout>
MyListAdapter: a class in the main_activity that extends the ArrayAdapter class so I can put in one row both TextView and a button.
private class MyListAdapter extends ArrayAdapter<String> {
private int layout;
public MyListAdapter(Context context, int resource, List<String> objects) {
super(context, resource, objects);
layout= resource;
}
#Override
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder mainHolder= null;
if (convertView == null) {
LayoutInflater inflater = LayoutInflater.from(getContext());
convertView= inflater.inflate(layout, parent, false);
ViewHolder viewHolder= new ViewHolder();
viewHolder.item= (TextView) convertView.findViewById(R.id.itemText);
viewHolder.btn= (Button) convertView.findViewById(R.id.doneBtn);
viewHolder.btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getContext(), itemArray.get(position), Toast.LENGTH_SHORT).show();
}
});
convertView.setTag(viewHolder);
}
else {
mainHolder= (ViewHolder) convertView.getTag();
mainHolder.item.setText(getItem(position));
}
return convertView;
}
public class ViewHolder {
TextView item;
Button btn;
}
}
Thanks for all! :)
but when it has normal size (layout_heigh=wrap_content)
It is a very bad idea using a ListView by giving it a height=wrap_content.
This forces ListView to measure a few children out of the adapter at layout time, to know how big it should be.
You can check it your self debugging the getView() method inside the adapter.
In your case, using a LinearLayout just add a top margin (50dp as the Button) to your listView and use layout_heigh=match_parent.
Otherwise use a RelativeLayout.
Change your listview to take up as much room as is can considering the height of any sibling views (in this case your button). Here's how to do that with the android:layout_weight attribute
<?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"
android:orientation="vertical">
<Button
android:layout_width="match_parent"
android:layout_height="50dp"
android:text="Add Task"
android:onClick="addTask" />
<ListView android:id="#+id/myListView"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1"
android:drawSelectorOnTop="false"/>
</LinearLayout>
I'm having a problem that all my ListViews Items are showing like this:
As you guys can see Hello World! is a TextView and is showing perfectly.
But the ListView itens are showing like they are disabled.
This is my Activity's onCreate method:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_open_answers);
ctx = getApplicationContext();
Intent intent = getIntent();
usersurvey_id = intent.getIntExtra("usersurvey_id", -1);
list = (ListView) findViewById(R.id.listview_answers);
getAnswers();
AnswersArrayAdapter adapter = new AnswersArrayAdapter(ctx, answersList);
list.setAdapter(adapter);
list.setClickable(false);
list.setEnabled(true);
}
This is my Custom Adapter:
#Override
public View getView(int position, View convertView, ViewGroup parent){
Answers answerItem = answersList.get(position);
ViewHolder holder;
if(convertView == null){
LayoutInflater inflater = (LayoutInflater) ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.listitem_answers, null);
holder = new ViewHolder();
holder.question = (TextView) convertView.findViewById(R.id.tv_texto_pergunta);
holder.answer = (TextView) convertView.findViewById(R.id.tv_texto_resposta);
convertView.setTag(holder);
}else{
holder = (ViewHolder) convertView.getTag();
}
holder.question.setText(getQuestionById(answerItem.getAnswer_question_id()));
holder.answer.setText(answerItem.getAnswer_answer());
return convertView;
}

I now this is a bit old but i just stumbled across this post.
Could it be that you're using the wrong context? I think you should pass the current context of your Activity, like so:
ctx = getContext();
or like this:
AnswersArrayAdapter adapter = new AnswersArrayAdapter(this, answersList);
try this.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#D0D0D0">
<TextView
android:id="#+id/tv_pergunta"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textStyle="bold"
android:text="Pergunta:"/>
<TextView
android:id="#+id/tv_texto_pergunta"
android:layout_width="fill_parent"
android:layout_height="60sp"
android:layout_below="#id/tv_pergunta"
android:text="Texto da pergunta"/>

Show your theme(application/activity) selected in AndroidManifest.xml. I guess it's the problem.
I followed #Aun tip and solved my problem.
I just had to set manually all my app's colors.
try this line
android:textColor="#000000" in your TextView
I am having problems with ListView on android. I have an Activity with an EditText view and a button. The idea is user should enter some info in the EditText field, touch the Search button which retrieves a list from a web service that it is displayed in the same activity below the EditText and the Button. Everything fine, I got the data from Internet but items weren't displaying. I was using the notifyDataSetChanged(). After a couple of hours with no success, I decided trying to put some items manually and it turns out that again nothing was displayed, hence I think I am doing something wrong when I am trying to set the listview and the adapter. So here is the code..
the xml of the activity activity_search.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="5dp">
<EditText
android:id="#+id/edit_search"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="5"
android:inputType="text"
android:hint="Enter info"
android:ems="10" >
<requestFocus />
</EditText>
<Button
android:id="#+id/button_search"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#android:drawable/ic_menu_search"
android:contentDescription="Search"
android:ems="10" />
</LinearLayout>
<ListView
android:id="#+id/listview_items"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawSelectorOnTop="false" />
The XML of the item row.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_margin="5dp">
<TextView
android:id="#+id/row_code"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/Common_TextContent"
android:textAppearance="#android:style/TextAppearance.Holo.Medium" />
<TextView
android:id="#+id/row_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:text="#string/Common_TextContent"
android:textAppearance="#android:style/TextAppearance.Holo.Small" /></LinearLayout>
the custom Adapter:
public class ItemsListAdapter extends ArrayAdapter<ItemsList> {
private int[] colors = new int[] { 0x30ffffff, 0x30808080 };
public AssetListAdapter(Context context,
List<ItemsList> itemsList) {
super(context, 0, itemsList);
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
convertView = LayoutInflater.from(getContext()).inflate(R.layout.row, null);
}
convertView.setBackgroundColor(colors[position % colors.length]);
TextView code = (TextView) convertView.findViewById(R.id.row_code);
code.setText(getItem(position).getCode());
TextView name = (TextView) convertView.findViewById(R.id.row_name);
name.setText(getItem(position).getName());
return convertView;
}
and the onCreate method on the Activity
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_search);
_listView = (ListView) findViewById(R.id.listview_items);
_listItems = new ArrayList<ItemsList>();
_listItems.add(new ItemsList ("cosa1", "cosa1", "cosa1", "cosa1"));
_listItems.add(new ItemsList ("cosa2", "cosa2", "cosa2", "cosa2"));
_listItems.add(new ItemsList ("cosa3", "cosa3", "cosa3", "cosa3"));
_adapter = new ItemsListAdapter(this, _listItems);
_listView.setAdapter(_adapter);
}
The ItemsList is just an Object with 4 strings with all the getters implemented.
When I debug in the getView method of the Adapter, the view (convertView) is created and it has the right information. It is just that is not showing those in the screen. What am I doing wrong?
Thanks...
Your second LinearLayout has a height of match_parent. Try wrap_content instead.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="5dp">
