How to animate a TextView to act like a Button when long pressed?
I've created a TextView using this code
<TextView
android:text="Start"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/btnStart"
android:layout_alignParentBottom="true"
android:gravity="center"
android:clickable="true"
android:focusable="true"
android:longClickable="true"
android:paddingTop="20dp"
android:paddingBottom="20dp"
android:textAllCaps="true"
android:textStyle="bold"
android:background="#drawable/rectangle"
android:textSize="20sp"/>
but even setting android:longClickable="true" the TextView does not show the bubble animation when is long pressed. The expected result is here.
You need to set selectable background:
<TextView
android:background="?attr/selectableItemBackground"
.../>
But seeing that you already use android:background you can also use android:foreground instead of it:
<TextView
android:foreground="?attr/selectableItemBackground"
.../>
But beware that android:foreground will work only starting with API 21 (Lollipop).
If you need to have your #drawable/rectangle AND to support Android <5.x then you'll have to create a custom drawable for this to work. See the RippleDrawable documentation for details.
I think you are looking for ripple effect in listview. please add
android:background="?attr/selectableItemBackground". in your textview
If you need to set your custom background you can do something like this:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:drawable="#drawable/state_one"></item>
<item android:state_enabled="true" android:drawable="#drawable/state_two"></item>
<transition
android:fromId="#+id/usual"
android:toId="#+id/selected" >
<animation-list>
<!--fill in your animation here-->
</animation-list>
</transition>
</selector>
You have to use the xml above instead android:background="#drawable/rectangle".
Also you need to design state_one and state_two in your drawables.
I've tried a lot to get things working, but without any sort of success.
I have implemented a custom listview that displays 3 textviews, added the custom adapter of my hands and things work correctly, I've done the registerForContextMenu(View of listview) and when I press items displayed, it shows a perfect blue highlight around my item, and when I press it long the same happens and then it shows me the menu. Okay. Then I added a button inside my custom listview displaying one color if certain things happen, displaying another one viceversa. After I modified my custom adapter to include my button and setting the change-color logic, if I long press my items I have no more highlight around, but the context menu is preserved.
Why is this happening?
I tried a lot searching on Stack and Google, but every solution I found was not working with my app. I tried also to insert a custom selector, it works fine when I exclude the button from my listview design, I suppose the button is the culprit, but I can't find out a way to resolve this problem. I suppose is something related to the "background" - "drawable" of the button, but I am here to ask you some help.
Thanks in advance.
Some code if it can interest you:
listviewdesign.xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
>
<TextView
android:id="#+id/text1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_marginLeft="5dp"
android:layout_centerVertical="true"
android:gravity="center"
/>
<TextView
android:id="#+id/text2"
android:singleLine="false"
android:maxEms="8"
android:layout_width="80dp"
android:layout_height="wrap_content"
android:layout_marginLeft="25dp"
android:layout_toLeftOf="#+id/text3"
android:layout_toRightOf="#+id/text1"
android:layout_centerVertical="true"
android:gravity="center"
/>
<TextView
android:id="#+id/text3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="25dp"
android:layout_marginRight="5dp"
android:layout_toLeftOf="#+id/btn1"
/>
<Button
android:id="#+id/btn1"
android:layout_width="10px"
android:layout_height="10px"
android:layout_alignParentRight="true"
android:layout_marginTop="20dp"
/>
</RelativeLayout>
mainactivitylayout.xml:
<LinearLayout ...>
<ListView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#android:id/list"
(when I add selector: android:listSelector="#xml/myselector")
android:clickable="false"
/>
</LinearLayout>
And my selector for completeness:
<selector xmlns:android="http://schemas.android.com/apk/res/android"
class="class of project">
<item android:state_pressed="true"
android:drawable="#drawable/pressed"/>
<item android:state_focused="true"
android:drawable="#drawable/focused"/>
<item android:state_selected="false"
android:state_pressed="false"
android:drawable="#drawable/normal"/>
<item android:drawable="#drawable/normal"/>
</selector>
Where those drawable items are correctly setup such as:
<resources>
<drawable name="pressed">#FF00A5FF</drawable>
<drawable name="focused">#FF0000FF</drawable>
<drawable name="normal">#00000000</drawable>
</resources>
Thanks!
You need to place "myselector.xml" in drawable folder.
android:listSelector="#xml/myselector"
this line should be
android:listSelector="#drawable/myselector"
There is a default rectangular background in my Image Button. I want to remove this
This is related codes:
<ImageButton
android:layout_width="62dp"
android:layout_weight="1"
android:layout_height="60dp"
android:id="#+id/im16"
android:layout_gravity="fill_horizontal"
android:src="#drawable/off1"/>
Just try this
<ImageButton
android:layout_width="62dp"
android:layout_weight="1"
android:layout_height="60dp"
android:id="#+id/im16"
android:layout_gravity="fill_horizontal"
android:background="#drawable/off1"/>
just change your android:src to android:background
You will want to set the background of the imageButton to be something invisible. I do this by making the following XML drawable and setting it to the ImageButton's background. This will let the button still show a color when it is clicked, but blank otherwise.
blank_selector.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:drawable="#color/some_color" />
<item android:drawable="#android:color/transparent" />
</selector>
<ImageButton
android:layout_width="62dp"
android:layout_weight="1"
android:layout_height="60dp"
android:id="#+id/im16"
android:layout_gravity="fill_horizontal"
android:src="#drawable/off1"
android:background="#drawable/blank_selector" />
best solution is
android:background="#null"
I am designing an app for multiple devices.In that I am using a imageview and using selector i am setting the background image depends on the state.I works fine for all the devices except only one 10 inch device.
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"

Thanks in advance.
Probabilly you have to put in your manifest file: hardwareAccelerated="true"
Try that and let me know if it worked!
Use ImageButton there are two methods setBackgroundResource, setImageResource to set resources for button(which one will be pressed) and for image itself
You need to add android:clickable="true" to the LinearLayout or set a OnClickListener there. Otherwise your selector background does not get activated.
Use ImageButton instead of ImageView to get the selector work.
If you can provide the different states of the image then see this
post
Otherwise...
Use a LayerDrawable for the image source. One layer is the actual image, the other layer is a state list selector.
LayerDrawable d = new LayerDrawable(new Drawable[]{getResources().getDrawable(R.drawable.my_image), getResources().getDrawable(R.drawable.my_selector_list)});
imageView.setImageDrawable(d);
Or you can define a layer drawable XML resource and use that in your layout XML.
I'm trying to have an image (as the background) on a button and add dynamically, depending on what's happening during run-time, some text above/over the image.
If I use ImageButton I don't even have the possibility to add text.
If I use Button I can add text but only define an image with android:drawableBottom and similar XML attributes as defined here.
However these attributes only combine text & image in x- and y-dimensions, meaning I can draw an image around my text, but not below/under my text (with the z-axis defined as coming out of the display).
Any suggestions on how to do this? One idea would be to either extend Button or ImageButton and override the draw()-method. But with my current level of knowledge I don't really know how to do this (2D rendering). Maybe someone with more experience knows a solution or at least some pointers to start?
For users who just want to put Background, Icon-Image and Text in one Button from different files: Set on a Button background, drawableTop/Bottom/Rigth/Left and padding attributes.
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/home_btn_test"
android:drawableTop="#drawable/home_icon_test"
android:textColor="#FFFFFF"
android:id="#+id/ButtonTest"
android:paddingTop="32sp"
android:drawablePadding="-15sp"
android:text="this is text"></Button>
For more sophisticated arrangement you also can use RelativeLayout (or any other layout) and make it clickable.
Tutorial: Great tutorial that covers both cases: http://izvornikod.com/Blog/tabid/82/EntryId/8/Creating-Android-button-with-image-and-text-using-relative-layout.aspx
There's a much better solution for this problem.
Just take a normal Button and use the drawableLeft and the gravity attributes.
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:drawableLeft="#drawable/my_btn_icon"
android:gravity="left|center_vertical" />
This way you get a button which displays a icon in the left side of the button and the text at the right site of the icon vertical centered.
You can call setBackground() on a Button to set the background of the button.
Any text will appear above the background.
If you are looking for something similar in xml there is:
android:background attribute which works the same way.
<Button
android:layout_width="0dp"
android:layout_weight="1"
android:background="#drawable/home_button"
android:drawableLeft="#android:drawable/ic_menu_edit"
android:drawablePadding="6dp"
android:gravity="left|center"
android:height="60dp"
android:padding="6dp"
android:text="AndroidDhina"
android:textColor="#000"
android:textStyle="bold" />
Just use a LinearLayout and pretend it's a Button - setting background and clickable is the key:
<LinearLayout
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#android:drawable/btn_default"
android:clickable="true"
android:orientation="horizontal" >
<ImageView
android:id="#+id/img"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginLeft="5dp"
android:src="#drawable/image" />
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_margin="5dp"
android:text="Do stuff" />
</LinearLayout>
just replace
android:background="#drawable/icon"
with
android:background="#android:color/transparent"
android:drawableTop="#drawable/[your background image here]"
izz a pretty good trick.. ;)
I took a different approach from the ones stated here, and it is working really well, so I wanted to share it.
I'm using a Style to create a custom button with image at the left and text at the center-right. Just follow the 4 "easy steps" below:
I. Create your 9 patches using at least 3 different PNG files and the tool you have at: /YOUR_OWN_PATH/android-sdk-mac_x86/tools/./draw9patch. After this you should have:
button_normal.9.png, button_focused.9.png and button_pressed.9.png
Then download or create a 24x24 PNG icon.
ic_your_icon.png
Save all in the drawable/ folder on your Android project.
II. Create a XML file called button_selector.xml in your project under the drawable/ folder. The states should be like this:
<item android:state_pressed="true" android:drawable="#drawable/button_pressed" />
<item android:state_focused="true" android:drawable="#drawable/button_focused" />
<item android:drawable="#drawable/button_normal" />
III. Go to the values/ folder and open or create the styles.xml file and create the following XML code:
<style name="ButtonNormalText" parent="#android:style/Widget.Button">
<item name="android:textColor" >#color/black</item>
<item name="android:textSize" >12dip</item>
<item name="android:textStyle" >bold</item>
<item name="android:height" >44dip</item>
<item name="android:background" >#drawable/button_selector</item>
<item name="android:focusable" >true</item>
<item name="android:clickable" >true</item>
</style>
<style name="ButtonNormalTextWithIcon" parent="ButtonNormalText">
<item name="android:drawableLeft" >#drawable/ic_your_icon</item>
</style>
ButtonNormalTextWithIcon is a "child style" because it is extending ButtonNormalText (the "parent style").
Note that changing the drawableLeft in the ButtonNormalTextWithIcon style, to drawableRight, drawableTop or drawableBottom you can place the icon in other position with respect to the text.
IV. Go to the layout/ folder where you have your XML for the UI and go to the Button where you want to apply the style and make it look like this:
<Button android:id="#+id/buttonSubmit"
android:text="#string/button_submit"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
style="#style/ButtonNormalTextWithIcon" ></Button>
And... voilà! You got your button with an image at the left side.
For me, this is the better way to do it! because doing it this way you can manage the text size of the button separately from the icon you want to display and use the same background drawable for several buttons with different icons respecting the Android UI Guidelines using styles.
You can also create a theme for your App and add the "parent style" to it so all the buttons look the same, and apply the "child style" with the icon only where you need it.
Important Update
Don't use normal android:drawableLeft etc... with vector drawables, else it
will crash in lower API versions. (I have faced it in live app)
For vector drawable
If you are using vector drawable, then you must
Have you migrated to AndroidX? if not you must migrate to AndroidX first. It is very simple, see what is androidx, and how to migrate?
It was released in version 1.1.0-alpha01, so appcompat version should be at least 1.1.0-alpha01. Current latest version is 1.1.0-alpha02, use latest versions for better reliability, see release notes - link.
implementation 'androidx.appcompat:appcompat:1.1.0-alpha02'
Use AppCompatTextView/AppCompatButton/AppCompatEditText
Use app:drawableLeftCompat, app:drawableTopCompat, app:drawableRightCompat, app:drawableBottomCompat, app:drawableStartCompat and app:drawableEndCompat
For regular drawable
If you don't need vector drawable, then you can
use android:drawableLeft, android:drawableRight, android:drawableBottom, android:drawableTop
You can use either regular TextView, Button & EditText or AppCompat classes.
You can achieve Output like below -
<Button android:id="#+id/imeageTextBtn"
android:layout_width="240dip"
android:layout_height="wrap_content"
android:text="Side Icon With Text Button"
android:textSize="20sp"
android:drawableLeft="#drawable/left_side_icon"
/>
You can use drawableTop (also drawableLeft, etc) for the image and set text below the image by adding the gravity left|center_vertical
<Button
android:id="#+id/btn_video"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:background="#null"
android:drawableTop="#drawable/videos"
android:gravity="left|center_vertical"
android:onClick="onClickFragment"
android:text="Videos"
android:textColor="#color/white" />
MaterialButton has support for setting an icon and aligning it to the text:
<com.google.android.material.button.MaterialButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="My button"
app:icon="#drawable/your_icon"
app:iconGravity="textStart"
/>
app:iconGravity can also be to start / end if you want to align the icon to the button instead of the text inside it.
Since version 1.5.0-beta01, app:iconGravity can also be top / textTop (commit)
<Button
android:id="#+id/groups_button_bg"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="Groups"
android:drawableTop="#drawable/[image]" />
android:drawableLeft
android:drawableRight
android:drawableBottom
android:drawableTop

Probably my solution will suit for a lot of users, I hope so.
What I am suggesting it is making TextView with your style. It works for me perfectly, and has got all features, like a button.
First of all lets make button style, which you can use everywhere...I am creating button_with_hover.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" >
<shape android:shape="rectangle" >
<corners android:radius="3dip" />
<stroke android:width="1dip" android:color="#8dbab3" />
<gradient android:angle="-90" android:startColor="#48608F" android:endColor="#48608F" />
</shape>
<!--#284682;-->
<!--border-color: #223b6f;-->
</item>
<item android:state_focused="true">
<shape android:shape="rectangle" >
<corners android:radius="3dip" />
<stroke android:width="1dip" android:color="#284682" />
<solid android:color="#284682"/>
</shape>
</item>
<item >
<shape android:shape="rectangle" >
<corners android:radius="3dip" />
<stroke android:width="1dip" android:color="#color/ControlColors" />
<gradient android:angle="-90" android:startColor="#color/ControlColors" android:endColor="#color/ControlColors" />
</shape>
</item>
</selector>
Secondly,
Lets create a textview button.
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="20dip"
android:layout_gravity="right|bottom"
android:gravity="center"
android:padding="12dip"
android:background="#drawable/button_with_hover"
android:clickable="true"
android:drawableLeft="#android:drawable/btn_star_big_off"
android:textColor="#ffffffff"
android:text="Golden Gate" />
And this is a result. Then style your custom button with any colors or any other properties and margins. Good luck
This code works for me perfectly
<LinearLayout
android:id="#+id/choosePhotosView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:gravity="center"
android:clickable="true"
android:background="#drawable/transparent_button_bg_rev_selector">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/choose_photo"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#android:color/white"
android:text="#string/choose_photos_tv"/>
</LinearLayout>
To combine Button and drawableTop and still get the click response, you can use button style #style/Widget.AppCompat.Button.Borderless to make it transparent.
<Button
android:id="#+id/settings"
style="#style/Widget.AppCompat.Button.Borderless"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableTop="#drawable/ic_baseline_settings_24"
android:drawableTint="?attr/colorPrimary"
android:text="#string/settings"
android:textColor="?attr/colorPrimary" />
<Button android:id="#+id/myButton"
android:layout_width="150dp"
android:layout_height="wrap_content"
android:text="Image Button"
android:drawableTop="#drawable/myimage"
/>
Or you can programmatically:
Drawable drawable = getResources.getDrawable(R.drawable.myimage);
drawable.setBounds(0, 0, 60, 60);
myButton.setCompoundDrawables(null, drawable, null, null);//to the Top of the Button
You can use this:
<Button
android:id="#+id/reset_all"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="5dp"
android:layout_weight="1"
android:background="#drawable/btn_med"
android:text="Reset all"
android:textColor="#ffffff" />
<Button
android:id="#+id/undo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:layout_weight="1"
android:background="#drawable/btn_med"
android:text="Undo"
android:textColor="#ffffff" />
in that i have put an image as background and also added text..!
Make a fake button.
It's really the only way
<FrameLayout
android:id="#+id/fake_button"
android:layout_width=" .. "
android:layout_height=" .. "
android:background="#android:color/transparent"
android:clickable="true"
android:onClick="tappedNext">
<ImageView
android:id="#+id/fake_image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/your_amazing_drawable" />
<TextView
android:id="#+id/fake_text"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:text="Next"
android:fontFamily="#font/ .. "
android:textColor="#color/ .. "
android:textSize=" .. " />
</FrameLayout>
<ImageView
android:id="#+id/iv"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"
android:src="#drawable/temp"
/>
