im quite new to android, so i apologise if this is a noob-ish question (:
i designed my list following the example found here: http://android-er.blogspot.com/2010/06/custom-arrayadapter-with-with-different.html
but what i would like to know is how would i go about adding setContentView(R.layout.main) so that i can display other (xml) elements along with the list?
thanks for any advice (:
You just edit your main.xml to look whatever you want it to look, eg:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<View android:id="#+id/emptyview"
android:layout_height="30dp"
android:layout_width="fill_parent"
/>
<ListView android:id="#+id/listview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:drawSelectorOnTop="true"
android:stackFromBottom="true"
android:layout_below="#id/emptyview"
android:headerDividersEnabled="true"
/>
</RelativeLayout>
Change your activity to extend only Activity, not ListActivity. Finally, in your activity you can then fetch your list view with:
ListView list = (ListView) findViewById(R.id.listview);
and do whatever you need to do with the list.
You create your main.xml
Add to it a ListView
<ListView android:layout_width="match_parent"
android:layout_height="match_parent" android:id="#+id/myListView"
android:divider="#ffa500" android:dividerHeight="1px"
android:background="#drawable/somedrawable_xml"
android:choiceMode="singleChoice"></ListView>
somedrawable_xml.xml could be any drawable example:
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#00ffa500" />
<stroke android:width="2dp" android:color="#ffffa500" />
<padding android:left="1dp" android:top="1dp" android:right="1dp"
android:bottom="1dp" />
Add a layout xmlFile myLayout.xml example: (I added imageView for demonstration) anyway what is important is the id of the textview
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/dasdasd">
<TextView android:text="TextView" android:layout_height="wrap_content"
android:id="#+id/thisIsTheTextView" android:layout_width="wrap_content" android:textAppearance="?
android:attr/textAppearanceLarge"></TextView>
<ImageView android:src="#drawable/icon" android:id="#+id/imageView1" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:layout_alignParentRight="true"></ImageView>
finally in your Activity
ArrayAdapter myAD=new ArrayAdapter(mContext,R.layout.myLayout,R.id.thisIsTheTextView,new String[] {"item1", "item2", "item3", "item4", "item5"});
myListView.setAdapter(myAD);

I'm getting data from Firebase Firestore to populate a ListView, and I would like to show a loading animation while the data is being fetched.
The code for layout
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout

<ListView android:id="#+id/list_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="gone"

</FrameLayout>
The code in java
private void finishLoadList(){
RelativeLayout loadingLayout = (RelativeLayout) findViewById(R.id.loading);
ListView listView = (ListView) findViewById(R.id.list_view);

Hello I'm using badge counter in navigation menu, but. I can't move to center vertically. I tried margin, height:match_parent but width shape not success.
( https://stackoverflow.com/a/33607630/4933464 )
Here my codes ( I use with shape ):
#drawable/menu_counter.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" >
<solid android:color="#ec443e" />
<padding
android:left="5dp"
android:right="5dp"
android:top="3dp"
android:bottom="3dp"/>
<corners android:radius="5dp" />
</shape>
#layout/menu_counter.xml
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:background="#drawable/menu_counter"
android:textAppearance="#style/TextAppearance.AppCompat.Body2"
android:textColor="#ffffff" />
Thanks.
Wrap it with a relative layout and add
android:layout_centerVertical="true"
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_centerVertical="true"
android:background="#drawable/menu_counter"
android:textAppearance="#style/TextAppearance.AppCompat.Body2"
android:textColor="#ffffff" />
</RelativeLayout>
Original DrawerLayout doesn't support badges. But there is a many useful library
MaterialDrawer : https://github.com/mikepenz/MaterialDrawer
Screenshots aviable on github page.
I'm having an issue with a ListView and a ScrollView and adding a drop shadow between the listview and the ScrollView.
I had made a shape, which works great with a ListView and a relative layout, but does not work with the ScrollView.
I have done the following - Dashboard List
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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"
android:layout_weight="1"
android:choiceMode = "singleChoice"
android:listSelector="#31ABD4"
android:drawSelectorOnTop="false"/>
<TextView android:id="#id/android:empty"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="No data"/>
</RelativeLayout>
Dashboard with scroll view
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#color/white" >
<View
android:layout_width="10dp"
android:layout_height="fill_parent"
android:background="#drawable/shadow_left" />
</RelativeLayout>
</ScrollView>
View
<?xml version ="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient
android:angle="180"
android:width="10dp"
android:centerX="0.1"
android:gravity="right"
android:startColor="#00000000"
android:endColor="#55000000"
android:type = "linear"
/>
</shape>
Edit - Attached Screenshots
Thank you all,
James
seems that you are missing the paddings on "Dashboard with scroll view"
try this instead
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingLeft="8dp"
android:paddingRight="8dp" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#color/white" >
<View
android:layout_width="10dp"
android:layout_height="fill_parent"
android:background="#drawable/shadow_left" />
</RelativeLayout>
</ScrollView>
I have a ListActivity that I'm trying to inflate a Button from this layout file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<Button
android:id="#+id/add_button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/add_prop"
android:layout_alignParentBottom="true"
/>
</LinearLayout>
Using this code:
View footer = getLayoutInflater().inflate(R.layout.footer, null);
ListView listView = getListView();
listView.setTextFilterEnabled(true);
listView.addFooterView(footer, null, false);
The problem is that since the list isn't so big that takes the entire screen (at least I think this is why) the button stays at the end of the list instead of sticking to the bottom because of the android:layout_alignParentBottom="true" property. What should I do to make it stick at the bottom?
You have to create a new layout file with this code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#+id/add_button" />
<Button
android:id="#+id/add_button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/add_prop"
android:layout_alignParentBottom="true" />
</RelativeLayout >
Then set it as content view of your Activity using setContentView()
I have an ListView element in my layout,with other views:
...
<ListView android:layout_height="wrap_content" android:id="#+id/listView1" android:layout_width="match_parent" android:visibility="gone" android:></ListView>
...
when the Activity is created I fill the Listview with an Array of values:
ListView list_ultime_ricette=(ListView) findViewById(R.id.listView1);
list_ultime_ricette.setVisibility(android.view.View.VISIBLE);
list_ultime_ricette.setAdapter(new ArrayAdapter<String>(Home.this, R.layout.list_item, ricette_name));
And this is list_item.xml:
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="10dp"
android:textSize="16dp" >
But when I try the whole, I see only the first element of my array, does anyone know why?
Don't put ListView inside of a ScrollView :)
Try changing list_item.xml to be this:
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="10dp"
android:textSize="16dp" >
Only change is settings layout_height to "wrap_content" instead of "fill_parent".
Don't put Listview inside a ScrollView
