I have a data-structure which is of type:
ArrayList<ArrayList<String>>;
...It contains a set of elements of a news feed; each element is itself a list of fields and each field is a tuple(key:value) where both key&value are of type String.
NOTE: the reason fields are stored in ArrayList is I don't always know how many the feed-parser will spurt out.
The view:
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ems="10"
android:id="#+id/news"
android:text="#string/news_and_events"
android:layout_row="6"
android:layout_column="4"
android:layout_columnSpan="3"
android:layout_rowSpan="3"
android:width="180dp"
android:height="245dp"
android:layout_marginBottom="10dp">
<!--FEED-->
<ListView
android:id="#android:id/list"
android:layout_height="match_parent"
android:layout_width="match_parent"
/>
</RelativeLayout>
The row-template I want to use is:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent">
<ImageView
android:id="#+id/picture"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_alignParentBottom="true"
android:layout_alignParentTop="true"
android:layout_marginRight="6dip"
android:contentDescription=""
/>
<!--STARTING WITH title-->
<TextView
android:id="#+id/title"
android:layout_width="fill_parent"
android:layout_height="26dip"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_toRightOf="#id/picture"
android:ellipsize="marquee"
android:singleLine="true"
android:text=""
android:textSize="20sp"
/>
<TextView
android:id="#+id/body"
android:layout_width="fill_parent"
android:layout_height="50dip"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true" />
</RelativeLayout>
As you can see there are 3-fields: title, body, image (a news feed).
So I'm completely stumped as to what type of adapter I should use.
All the ones' I've looked at don't seem to match what I want to do; specifically because of the data-structure I'm using.
Perhaps I should use a cursor adapter?
If so, how would I map this into a Relational-database?!
I think you should try using a BaseAdapter, it's the most flexible adapter Android has(I think)...
By doing so, you can implement a custom Adapter, which goes thru the ArrayList(using 2 cycles for extracting) and then parsing it to the visual components you specified.
Since it's constructor receives the context, the view and the data, you'll have the ImageView and so, there.
I designed one layout which have total 4 RelativeLayout one is outer cover and 3 are child of it. When I put White color in the outer layout than no spaces are left but when I put 9patch image as drawable image than little default padding/margin are left. Is there any properly which solve the padding/margin issue? I have tried margin negative but it will hide bit layout I think it is not proper solution, here is my layout
when I put white color as background than my layout look like
Here is the following code of my layout

From the 9-patch drawable image you posted:
The bottom line which indicates the horizontal data population on the view wasn't drawn from the starting point of left.
I am not sure about it. And I know I wasn't clear in explaining the above line.
Just check this:
Consider the below 9-patch is used as a background for a TextView. If you put some text in it, it will start from the area where the bottom line is drawn. Which mean it will start from the left and go all the way to right.
If you use the following 9-patch as a background and try the same thing which you did above. Will result in Text not written from the left. It leaves a bit padding.
That is the reason why you get such result. Of course I am 100% sure about it.
So, just to find out if this works. Try changing the bottom line to fill complete image.
I think you better apply the background color for which layout you want exactly.And one more keep the code so that we can understand easily what is your issue.
In main activity of my application I need a control which should look like ListPreference in PreferencesActivity. I mean, 2 lines: title and current value and down arrow icon on the right.
I've tried to use TwoLineListItem for this:
<TwoLineListItem android:id="#+id/twoLineListItem1"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:onClick="onButtonClick" android:focusable="true"
android:background="#android:drawable/list_selector_background">
<TextView android:layout_width="fill_parent"
android:textAppearance="?android:attr/textAppearanceLarge"
android:layout_height="wrap_content" android:id="#android:id/text1"
android:text="Upload into:" />
<TextView android:layout_below="#android:id/text1"
android:textAppearance="?android:attr/textAppearanceSmall"
android:layout_alignLeft="#android:id/text1" android:layout_height="wrap_content"
android:id="#android:id/text2" android:text="<not set>"
android:layout_width="wrap_content" />
<!-- <ImageView android:layout_width="wrap_content" android:layout_alignParentRight="true"
android:id="#android:id/selectedIcon"
android:src="???"> </ImageView> -->
</TwoLineListItem>
It all works except of arrow icon: I can't find proper resource which system uses for it.
How this could be solved?
Or maybe I should use another control instead of TwoLineListItem?
Or maybe even try to implement my activity as PreferencesActivity (thought I need some EditText controls in my activity)?
For the reference, what I need is on the left picture:

wow, this question is so old and i can't believe no one answered it correctly lol. the layout you were looking for is in the sdk tree under:
[android-sdk-root]/platforms/[your-platform]/data/res/layout/preference.xml
you'll find this and any other sdk defined layouts in this folder. fish around in the res folder and see what's available. sorry it's a year late, but there ya go.
Use this layout and modify according to your need...
<?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"
android:background="#FFFFFF">
<LinearLayout android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_alignParentLeft="true">
<TextView android:layout_width="fill_parent"
android:text="ggggggggg"
android:layout_height="wrap_content" android:id="#android:id/text1"
/>
<TextView android:layout_below="#android:id/text1"
android:text="ssssssssssss"
android:layout_height="wrap_content"
android:id="#android:id/text2"
android:layout_width="wrap_content" />
</LinearLayout>
<ImageView android:layout_width="wrap_content"
android:layout_alignParentRight="true"
android:id="#android:id/selectedIcon"
android:layout_height="wrap_content"
android:src="#drawable/icon"
/>
</RelativeLayout>
You might try using #android:drawable/btn_dropdown to get the system resource and setting that as the background.
When I run layout on a specific XML file, I get this:
This tag and its children can be replaced by one <TextView/>
and a compound drawable
What change should be done for the following xml code:
<LinearLayout android:id="#+id/name_layout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:background="#drawable/grouplist_single_left_grey_area" >
<ImageView android:id="#+id/photo_image"
android:layout_width="#dimen/thumbnail_width"
android:layout_height="#dimen/thumbnail_height"
android:paddingBottom="5dip"
android:paddingTop="5dip"
android:paddingRight="5dip"
android:paddingLeft="5dip"
android:layout_marginRight="5dip"
android:clickable="true"
android:focusable="true"
android:scaleType="fitCenter"
android:src="#*android:drawable/nopicture_thumbnail"
android:background="#drawable/photo_highlight" />
<TextView android:id="#+id/name"
android:paddingLeft="5dip"
android:layout_weight="1"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:textAppearance="?android:attr/textAppearanceLarge" />
</LinearLayout>
This is how it looks like on the screen:
The camera icon is the default. Clicking on that will give the user an option to choose another image.
To expand on Romain Guy's answer, here is an example.
Before:
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:padding="5dp" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="My Compound Button" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/my_drawable" />
</LinearLayout>
After:
<TextView
android:layout_marginTop="10dp"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="My Compound Button"
android:drawableRight="#drawable/my_drawable" android:padding="5dp" />
Merge the TextView and the ImageView into one, by using TextView's setCompoundDrawable*() methods, or using android:drawableLeft.
Thought I would try to get some extra puntos for this as well: you can add padding between the image and the text using android:drawablePadding. https://stackoverflow.com/a/6671544/1224741
Add tools:ignore="UseCompoundDrawables" to <LinearLayout>.
Sometimes it is possible to replace ImageView (or multiple) and TextView with one TextView with compound drawable(s). There are NOT many parameters which can be applied to compound drawable using native API and this TextViewRichDrawable library, but if you can manage one TextView instead of using LinearLayout you should definitely use it.
The list of attributes and parameters which can be applied to compound drawables:
Size: (YES, really):
<com.tolstykh.textviewrichdrawable.TextViewRichDrawable
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Some text"
app:compoundDrawableHeight="24dp"
app:compoundDrawableWidth="24dp"/>
Even set vector resource as drawable:
<com.tolstykh.textviewrichdrawable.TextViewRichDrawable
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Some text"
app:drawableTopVector="#drawable/some_vector_drawble"
app:drawableEndVector="#drawable/another_vector_drawable" />
Drawable's Padding using native API android:drawablePadding -> link
Here is an example:
A LinearLayout which contains an ImageView and a TextView can
be more efficiently handled as a compound drawable (a single
TextView, using the drawableTop, drawableLeft, drawableRight
and/or drawableBottom attributes to draw one or more images
adjacent to the text).
If the two widgets are offset from each other with margins, this
can be replaced with a drawablePadding attribute.
There's a lint quickfix to perform this conversion in the Eclipse
plugin.
From: Android Official API docs!
When I followed the code above, text inside the TextView doesn't set properly.
You need to set its gravity to center|start to achieve what shown in the asked question.
The textview looks like this:
<TextView
android:id="#+id/export_text"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:drawableLeft="#drawable/up_arrow"
android:drawableStart="#drawable/up_arrow"
android:gravity="center|start"
android:text="....."
android:textSize="#dimen/font_size15" >
</TextView>
the latest correct way at time of writing to add a compound drawable is using app:drawableStartCompat rather than android:drawableLeft.
<TextView
android:layout_marginTop="10dp"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="My Compound Button"
android:drawablePadding="5dp"
app:drawableStartCompat="#drawable/my_drawable" />
You can refer this code for example
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:text="#string/myName"
android:textAlignment="center"
android:textColor="#color/myColor"
app:drawableTopCompat="#drawable/image_name" />
If you don't want to change the ImageView and TextView, you can change the version in the AndroidManifest.xml as:
<uses-sdk`
android:minSdkVersion="8"
android:targetSdkVersion="18"
/>
If your version is android:targetSdkVersion="17" change it s "18".
Hope this will rectify. I did it and got it right
I don't know if this is an efficient solution. But using <androidx.appcompat.widget.LinearLayoutCompat> to wrap the imageView and TextView instead of <LinearLayout> will fix this error. Also by using LinearLayoutCompat, you will be able to adjust the image's width and height which you can't when using a drawableRight, drawableLeft, drawableTop or drawableBottom inside a TextView.
This warning is rather misleading. You can use a compound drawable using a TextView as others have suggested but it doesn't necessarily give you the desired result. You have very littler control over how you want your button to look like using a compound drawable, so it is better to just add tools:ignore="UseCompoundDrawables" and ignore this warning.
Another approach is embed the ViewImage into another LinearLayout (allow handle it with alone id):
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/blue_3"
android:layout_gravity="center_horizontal"
android:paddingTop="16dp" />
</LinearLayout>
<TextView
android:id="#+id/tvPrompt"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:paddingTop="16dp"
android:text="#string/xy" />
This tag and its children can be replaced by one <TextView/> and a compound drawable
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="vertical" >
<ImageView
android:id="#+id/imageview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusable="false"
android:contentDescription="."
android:padding="3dp"
android:src="#drawable/tab_home_btn">
</ImageView>
<TextView
android:id="#+id/textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="首页"
android:textSize="10sp"
android:textColor="#ffffff">
</TextView>
</LinearLayout>
I am trying to modify the design of Spinner widget. I can change the background, but I can't find a way to change the arrow icon on the right side. Is there a way to do it?
Thanks!
The whole thing is a single 9 patch png image. I've modified the entire look of spinners before by replacing the images. See this page: http://androiddrawableexplorer.appspot.com/
Specifically look at btn_dropdown_normal.9, btn_dropdown_pressed.9, btn_dropdown_selected.9 and btn_dropdown_disabled.9
You just need to provide your own versions of those images.
Also, you can place your "spinner bar" layout in a FrameLayout, together with the real spinner but set to invisible:
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="32dip"
>
<Spinner
android:id="#+id/theSpinner"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:visibility="invisible"
/>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="32dip"
android:background="#drawable/my_background"
android:padding="6dip"
android:clickable="true"
android:onClick="spinnerBarReplacementClicked"
>
<ImageView
android:id="#+id/replacementSelectImg"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:src="#drawable/my_drawable"
/>
<TextView
android:id="#+id/replacementSelectText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:layout_marginLeft="4dip"
android:layout_toLeftOf="#id/replacementSelectImg"
android:textColor="#000000"
android:textSize="14sp"
android:ellipsize="marquee"
android:singleLine="true"
/>
</RelativeLayout>
</FrameLayout>
and pass the clicks from your layout to the real spinner
private Spinner mSpinner;
mSpinner = (Spinner) findViewById(R.id.theSpinner);
public void spinnerBarReplacementClicked(View pV){
mSpinner.performClick();
}
