I have a listView with a button in each row. The problem is that I can click in my listView item and something happens, but my Button does not work, nothing happens. I've read some things about the solution, but none helped me.
Here's my list_row.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="16dp"
android:descendantFocusability="blocksDescendants"
>
<TextView
android:id="#+id/text_branche_cours"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="English"
/>
<TextView
android:id="#+id/text_trait"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text=" - "
/>
<TextView
android:id="#+id/text_designation"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Reading"
android:layout_marginRight="150dp"
/>
<Button
android:id="#+id/bAjouterJalon"
android:layout_width="58dp"
android:layout_height="wrap_content"
android:background="#drawable/ic_action_add_jalon"
/>
And here's my customadapter class:
public class CustomAdapter extends SimpleCursorAdapter {
private Context mContext;
private Context appContext;
private int layout;
private Cursor cr;
private final LayoutInflater inflater;
public CustomAdapter(Context context, int layout, Cursor c, String[] from, int[] to) {
super(context, layout, c, from, to);
this.layout = layout;
this.mContext = context;
this.inflater = LayoutInflater.from(context);
this.cr = c;
}
#Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
return inflater.inflate(layout, null);
}
#Override
public void bindView(View view, final Context context, final Cursor cursor) {
super.bindView(view, context, cursor);
final Button ajouter = (Button)view.findViewById(R.id.bAjouterJalon);
ajouter.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent retour = new Intent(mContext,OngletJalonsNotes.class);
mContext.startActivity(retour);
}
});
}
}
Thank you for the help.
#EDIT - my listview is unclickable now !!
you are making button focusable & focus on touch false so it will not detect your touch tab on your button, remove these two lines from your button tag in xml :
android:focusable="false"
android:focusableInTouchMode="false"
Example:
<Button
android:id="#+id/bAjouterJalon"
android:layout_width="58dp"
android:layout_height="wrap_content"
android:background="#drawable/ic_action_add_jalon"
/>

In your list_item xml put android:descendantFocusability="blocksDescendants"
in the LinearLayout .

mainActivity.listItem.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
FrameLayout v = (FrameLayout)view.findViewById(R.id.updateLayout);
Log.d("!!!",v.toString());

UPDATE
I solved this problem by extending SimpleCursorAdapter ,maybe someone share with another solution?
private class MyAdapter extends SimpleCursorAdapter{
private int layout;
public MyAdapter(Context context, int layout, Cursor c, String[] from, int[] to, int flags) {
super(context, layout, c, from, to, flags);
this.layout = layout;
}
#Override
public void bindView(View view, Context context, Cursor cursor) {
String id = cursor.getString(colId);
String title = cursor.getString(colText);
TextView idView = (TextView)view.findViewById(R.id.t_id);
idView.setText(id);
TextView textView = (TextView)view.findViewById(R.id.t_text);
textView.setText(title);
}
#Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
View view = getLayoutInflater().inflate(layout,parent,false);
return view;
}
#Override
public int getItemViewType(int position) {
return position;
}
#Override
public int getViewTypeCount() {
return getCount();
}
}
Custom LinearLayout component view not displaying content
Hi i have created a custom component view that extends LinearLayout and when i use this view on my xml, it doesnt become visible on the screen.
Here is the main view that is using this custom component
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/contentLinearLayout"
android:layout_width="#dimen/width"
android:layout_height="wrap_content"
android:orientation="vertical">
<ImageView
android:id="#+id/image"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ABB0B6" />
<com.jon.ui.EnableView
android:id="#+id/enableContainter"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
Here is the EnableView custom component code:
package com.jon.ui;
/**
*/
public class EnableView extends LinearLayout {
private static View enableView;
private static Button btnContactlessInfoAction;
private static LinearLayout btnMakeContactlessAction;
private static View makeContactlessView;
private static View.OnClickListener enableContaclessBtnClick = new View.OnClickListener() {
#Override
public void onClick(View v) {
}
};
private static View.OnClickListener contactlessHelpBtnClick = new View.OnClickListener() {
#Override
public void onClick(View v) {
}
};
private static ViewGroup viewContainer;
private final Context mContext;
public EnableContactlessView(Context context) {
super(context);
mContext = context;
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
inflater.inflate(R.layout.custom_component, this);
setOrientation(LinearLayout.VERTICAL);
}
public EnableContactlessView(Context context, AttributeSet attrs) {
super(context, attrs);
mContext = context;
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
inflater.inflate(R.layout.custom_component, this);
setOrientation(LinearLayout.VERTICAL);
}
#Override
protected void onAttachedToWindow() {
super.onAttachedToWindow();
}
public void initiate() {
btnMakeContactlessAction = (LinearLayout) this.findViewById(R.id.btn);
btnContactlessInfoAction = (Button) this.findViewById(R.id.info_btn);
btnContactlessInfoAction.setOnClickListener(contactlessHelpBtnClick);
}
#Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
}
}
Below is the
View's layout xml i use to inflate from EnableView class called custom_component.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:id="#+id/btn"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginRight="9dp"
android:layout_weight="3"
android:background="#color/button_colour"
android:gravity="center"
android:paddingBottom="9dp"
android:paddingTop="9dp">
<ImageView

<TextView

android:layout_height="25dp"
android:layout_gravity="center_vertical|end"

</LinearLayout>
Do not override onLayout if you're leaving it empty, remove that function. onLayout is used to measure the parent and its children, if you leave it empty nothing is getting measured.
My app has listview inside dialogueFragment , when user chose item it should Toast , in my case items unclickable .
DialogueFragment
public class HistoryDialogue extends DialogFragment {
ListView list ;
Cursor c ;
HistoryAdapter adapter ;
Context context ;
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
LayoutInflater inflater = getActivity().getLayoutInflater();
View view = inflater.inflate(R.layout.history,null);
list = (ListView)view.findViewById(R.id.listView);
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
ContentResolver resolver = getActivity().getContentResolver();
c=resolver.query(Contract.SaveRunning.CONTENT_URI,null,null,null,null);
adapter= new HistoryAdapter(getActivity(),c,0);
list.setAdapter(adapter);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(getActivity(),"keep going ",Toast.LENGTH_LONG).show();
}
});
builder.setView(list);
return builder.create();
}
}
CursorAdapter
public class HistoryAdapter extends CursorAdapter {
public HistoryAdapter(Context context, Cursor c, int flags) {
super(context,c, flags);
}
#Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
return LayoutInflater.from(context).inflate(R.layout.historylist, parent, false);
}
#Override
public void bindView(View view, Context context, Cursor cursor) {
TextView text = (TextView) view.findViewById(R.id.text);
String body = cursor.getString(cursor.getColumnIndex("name"));
text.setText(body);
}
}
history.xml
<ListView

android:layout_width="match_parent"
android:layout_height="match_parent"

android:layout_gravity="center_horizontal" />
historylist.xml
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"

android:layout_height="35dp"
android:background="#drawable/delete"
android:id="#+id/btn"
android:layout_margin="10dp"
android:layout_weight="0"
/>
Add android:focusable="false" in your ListView (in history.xml ) and Item main layout (in historylist.xml).
<ListView
xmlns:android="http://schemas.android.com/apk/res/android"
android:focusable="false"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/listView"
android:layout_gravity="center_horizontal" />
and
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:focusable="false"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="60dp">
...
Add this line to your CursorAdapter's bindView:
((ViewGroup)row).setDescendantFocusability(ViewGroup.FOCUS_BLOCK_DESCENDANTS);
if it isn't enough, add clickable="false" to your historylist.xml's Button
I have created ListView with checkbox and textview(with custom background) in every row.
When I click on a row, checkbox and textview get highlighted with a listview row, but I want to get highlighted only the listview row without checkbox and textview after I click on the row. Could you help me please?
This is what I want after click on a row: http://tinypic.com/r/14kfpza/5.
This is what I have after click on a row: http://tinypic.com/r/2mr5w9c/5.
Thank you
My adapter for listview:
public class MyAdapter<String> extends ArrayAdapter<String>{
Context ctx;
List<String> content;
public MyAdapter(Context context, List<String> objects) {
super(context, R.layout.listview_row ,objects);
this.ctx = context;
this.content = objects;
}
public View getView(int position, View convertView, ViewGroup parent){
View row = convertView;
if(row == null){
LayoutInflater inflater=getLayoutInflater();
row=inflater.inflate(R.layout.listview_row, parent, false);
}
TextView desc = (TextView)row.findViewById(R.id.textView1);
String name = content.get(position);
desc.setText(name.toString());
return row;
}
}
listview_row.xml:
<?xml version="1.0" encoding="utf-8"?>

Write this in ur listView xml .
android:addStatesFromChildren="false"
This will not send the click events to the children of listView
OK, I have solved it, with custom TextView, the setPressed method is overwritten. The same I have done with CheckBox.
public class TextViewForListView extends TextView{
public TextViewForListView(Context context) {
super(context);
}
public TextViewForListView(Context context, AttributeSet attrs) {
super(context, attrs);
}
public TextViewForListView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
#Override
public void setPressed(boolean pressed) {
if (pressed && (this.getParent() instanceof View) && ((View) this.getParent()).isPressed()) {
return;
}
super.setPressed(pressed);
}
}
I want to add an button to the footer of listview, I'm using horizontal listview, The adapter class:
public ItemAdapter(Context context, int layout, Cursor c,String[] from, int[] to) {
super(context, layout, c, from, to,0);
this.layout = layout;
inflator= LayoutInflater.from(context);
}
I return the newView and bindView:
public View newView(Context context, Cursor cursor, ViewGroup parent) {
View v = inflator.inflate(layout, parent, false);
TextView footer = (TextView)v.findViewById(R.id.bAdd);
return v;
}
#Override
public void bindView(View v, final Context context, Cursor c) {
final int id = c.getInt(c.getColumnIndex(ItemDb.ID));
final String name = c.getString(c.getColumnIndex(ItemDb.NAME));
}
and the activity class:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String[] from = new String[] { ItemDb.NAME, ItemDb.CONDITION, ItemDb.EMAIL};
int[] to = new int[] { R.id.etItemName, R.id.etItemCondition, R.id.etEmail };
itemAdapter = new ItemAdapter(this,R.layout.list_item, null, from, to);
this.setListAdapter(itemAdapter);
}
How can I add the button in listview footer?
Here is my 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" >

Override getCount() of listview adapter to return data.size()+1 elements;
In getView() insert something like this:
if (position == data.size()){
return getFooterView();
}
In getFooterView() inflate proper layout with button.
