I have found that you can add or merge textviews onto a bitmap. I have 4 textviews that I would like to merge onto the top of the image.
Here is a screenshot of what I would like to achieve (although at the minute this is textviews at the top separate to the image):
the image is below the textviews. Image header in top right is for what image No it is
So what I am trying to do is once I click the send button it "prints" or merges these Textviews onto the image bitmap below so that I can then save or send the image(with the textviews in it) as one file to my server/device.
So far I have used Canvas.draw() method although it seems to overwrite each other and I am trying to keep the same layout as the screenshot.
Can anyone help?
Try this...

Give background as transparent color and border to textviews.
You can set bitmap to imageview by
ImageView mImg;
mImg = (ImageView) findViewById(R.id.(your xml img id));
mImg.setImageBitmap(img);

There's a linear layout given with a TextView, which contains an image. I want to position the image on the left-bottom side of the TextView.
I did this with android:drawable:Left
<TextView
android:id="#+id/xmpp_chatlist_tv_partnerID_inc_Message"
android:layout_width="match_parent"
android:layout_height="80sp"
android:padding="6dip"
android:textColor="#color/black"
android:background="#drawable/round_corners"
android:layout_weight="0.125"
android:drawableLeft="#drawable/xmpp_notation"
android:drawablePadding="5dp"
android:gravity="left">
</TextView>
I also did this:
textView_partnerID_inc.setCompoundDrawablesWithIntrinsicBounds(
R.drawable.xmpp_notation, 0, 0, 0);
How to get the image shown on the left-bottom side?
Either you can use LinearLayout like this:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<TextView
android:id="#+id/label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Text aligned bottom left"/>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/apk_icon"
android:layout_gravity="left"/>
</LinearLayout>
Or you can use a RelativeLayout like so:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="#+id/label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Text aligned bottom left"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"/>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/apk_icon"
android:layout_alignParentLeft="true"
android:layout_below="#+id/label"/>
</RelativeLayout>
Or using a Drawable, you can do this by adding gravity top:
<TextView
android:id="#+id/xmpp_chatlist_tv_partnerID_inc_Message"
android:layout_width="match_parent"
android:layout_height="80sp"
android:padding="6dip"
android:textColor="#color/black"
android:background="#drawable/round_corners"
android:layout_weight="0.125"
android:drawableLeft="#drawable/xmpp_notation"
android:drawablePadding="5dp"
android:gravity="left|top">
</TextView>
<?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">
<TextView
android:id="#+id/label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Text aligned bottom left"
android:layout_alignParentLeft="true"
android:layout_alignParentBottom="true"/>
</RelativeLayout>
than add the image
I created linearlayout with two buttons in center (buttons 1 and 2), but I can't manage it to create the view 3 on top, which I need to make it fill whole width and adjust it's height by it (keep proportions). How do I create third view?
Image:
Code:
<?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:background="#drawable/bg"
android:layout_gravity="center_horizontal"
android:orientation="horizontal">
<LinearLayout
android:orientation="vertical"
android:layout_gravity="center_vertical"
android:layout_width="fill_parent" android:layout_height="wrap_content" >
<ImageButton
android:background="#drawable/btn_one"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_weight="1.0" />
<ImageButton
android:background="#drawable/btn_second"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_weight="1.0" />
</LinearLayout>
I would recommend you use relative layouts, they are the closest thing in android to an "absolute layout" replace the button tags with Image button tags
<?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">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true">
</RelativeLayout>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Button"
android:id="#+id/button2"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="215dp" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Button"
android:id="#+id/button3"
android:layout_below="#+id/button2"
android:layout_alignStart="#+id/button2" />
</RelativeLayout>
try this code set height and width what size of image button you need and simple look what you need.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">

android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1">
<ImageButton
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="0.2"
android:orientation="vertical"
android:gravity="center">
<ImageButton
android:layout_width="200dp"
android:layout_height="50dp"/>
<ImageButton
android:layout_width="200dp"
android:layout_height="50dp" />
</LinearLayout>
I am new to android programming and I am trying to slide my view over image.This is my code(Not sure if this is the right way)

I want to scroll my cardview over image keeping image fixed.something like eclipsing the image.
and after scrolling completely the image should get hidden.(I dont want it to flow under toolbar)
Try to place your CardView into ScrollView and add CardView's marginTop which equals to your Image's height.
I've the following xml file:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<FrameLayout
android:id="#+id/topFragment"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center">
<ImageView
android:id="#+id/imageViewTest"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/icon_00" />
<TextView
android:id="#+id/textViewTest"
android:layout_below="#+id/imageViewTest"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="This is a Test"/>
</RelativeLayout>
<FrameLayout
android:id="#+id/bottomFragment"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom|center_horizontal" />
</LinearLayout>
The first FrameLayout contains a fragment, which contains some buttons.
The RelativeLayout contains for example an image (changig size) and a text.
The last FrameLayout contains also a fragment, which contains either some buttons or some text or an image.
My aim is, that:
- the first FrameLayout is on top (that works)
- the elements in the RelativeLayout are centered in the middle of the screen (doesn't work)
- the last FrameLayout is on the bottom (doesn't work)
It should look like this:
My previous attempts with android:gravity="center" in the RelativeLayout and android:layout_gravity="bottom|center_horizontal" for the second FrameLayout failed.
Change the LineareLayout to Relative and use layout_centerInParent for the middle layout and alignParentBottom for the last one.
The top View will be anchored to the top by default
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"> //removed orientation as it won't be needed anymore
<FrameLayout
android:id="#+id/topFragment"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<RelativeLayout
android:layout_width="wrap_content" // change here
android:layout_height="wrap_content"
android:layout_centernInParent="true"> // here
<ImageView
android:id="#+id/imageViewTest"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/icon_00" />
<TextView
android:id="#+id/textViewTest"
android:layout_below="#+id/imageViewTest"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="This is a Test"/>
</RelativeLayout>
<FrameLayout
android:id="#+id/bottomFragment"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true" /> //here
</RelativeLayout>
Use relative layout and use android:layout_centerHorizontal="true" instead of gravity.

I've got a few linear layouts stacked on top of each other, the centre one has an imageview. I'm trying to get a textview on top of the imageview in the centre however I'm having trouble. I've tried with relative layout however it messes up all my other layouts. Any simple solutions to this?

I'm trying to get the text view on top of the id/picPreview image view
LinearLayout is designed to place layouts/views in a row (linearly).
One solution would be something like this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="6"
android:orientation="vertical" >
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/picPreview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#000000"
android:contentDescription="#string/imageDesc"
android:layout_centerInParent="true"
android:src="#null" />
<TextView
android:id="#+id/picPreviewLbl"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerInParent="true"
android:text="Overlay" />
</RelativeLayout>
</LinearLayout>
Why not just use a TextView in place of the centered ImageView and then set the background of the text be the solid color that you are currently using? Eg.
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#000000"
android:text="Sample Text" ... />
