Why my TextView is Scrolling?
<TextView
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/rl_logo_header"
android:layout_marginTop="5dp"
android:autoLink="web"
android:descendantFocusability="blocksDescendants"
android:ellipsize="end"
android:focusable="false"
android:maxLines="3"
android:text="Should my school be focused on -- Teaching and Learning come as words which are very closely related, But they convey very different meanings and can not be used interchangeably."
android:textColor="#color/black" />
The content for this view could be text and may also contain HTML content. Hence I have set autoLink to true. The issue is, if either the autoLink or the textIsSelectable is true, then the textview starts to scroll similar to(MovementMethod) when its content is more than 3 lines. I am looking for a way to stop/disable this textview scrolling.
I tried to disable the scrolling using setEnable(false) for the text view, however all the links in the textview could not be clicked thereafter.
I think there has to be a straight forward way to achieve "non-scrollable textview" which may contain html content in them.
autoLink controls whether the TextView will parse URLs and highlight them as such. It has nothing to do with rendering HTML.
Your TextView is scrolling because you've set android:maxLines="3"
I would like to implement a auto scrolling text view in a native Android app.
Something like a vertically scrolling marquee. The idea being that it looks something similar to an autocue, the text will remain static and scroll once more text has been provided.
I am happy to work out the logic of scrolling the text when new text arrives. I am just looking for ideas on how to have that text feed/scroll effect animation.
Thank you
Maybe start here to make the textview scrollable:
Making TextView scrollable on Android
After that, you should be able to use an object animator, such as:
ScrollTo(0,250) with animation Android ScrollView
Do like:
in XML:
<TextView
android:id="#+id/textView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="0.0dp"
android:scrollbars="vertical"
android:scrollbarAlwaysDrawVerticalTrack="true"
android:maxLines="5" />
And in java:
textView.setMovementMethod(new ScrollingMovementMethod())
You Just check it and refer this answer.

I'm learning the relative layout and wrote a little test layout to simulate a login page:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="match_parent"
android:layout_width="match_parent">
<TextView android:id="#+id/labelUsername"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="username:"
android:layout_centerVertical="true"/>
<EditText android:id="#+id/txtUsername"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:hint="input username here"
android:layout_toRightOf="#id/labelUsername"
android:layout_alignBaseline="#id/labelUsername"/>
<TextView android:id="#+id/labelPassword"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="password:"
android:layout_below="#id/txtUsername"
android:layout_alignParentLeft="true"/>
<EditText android:id="#+id/txtPassword"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:hint="input password here"
android:layout_below="#id/txtUsername"
android:layout_alignLeft="#id/txtUsername"
android:layout_alignBaseline="#id/labelPassword"/>
</RelativeLayout>
What I want is putting the Username Label and Textfield above the Password Label and TextField. But the result is reverted, password are above!
I think the problem is the "android:layout_below" property in labelPassword, if I set it to below labelUsername, it works, however because the textfield is much bigger than label, the both textfields are in this case overlayed. So i try to make the labelPassword below the txtUsername, but it performs strange, I don't understand.
By the way, is there any guideline when I build layout with Relative Layout?
What should I put there at first?
What should I put at last?
thanks!
I think what you are trying to achieve here is trying to get both the username and password fields vertically centered, and the password field below the username field. The error in your layout is that you only tell the username textview and edittext to center vertically, and relative layout centeres the layouts after having arranged them. So your username field is centered, while the password is left on top.
What you should do is tell the parent(RelativeLayout) to vertically center all its child elements.
For that simply remove this attribute from the "username" TextView element :
android:layout_centerVertical="true"
And add this attribute to your RelativeLayout element:
android:gravity="center_vertical" //tells RelativeLayout to vertically center all child elements
In this case i would recommend using a LinearLayout but you can continue using RelativeLayout for now. Hope it helps!
To answer your concrete question, it's because android:layout_centerVertical="true" rule you are applying to labelUsername.
It seems that the relative position doesn't work well, when the elements you are refering to, are centered. And it also doesn't make sense, in this case, because you probably want the whole form centered, not only the username fields and then put the password bellow.
You can put the elements in a containing element (another relative layout, or linear layout, or table layout, etc.) and center that element. That works. Or to center all the contents, you can add android:gravity="center" to the containing layout.
As you go through the different Layouts you will find that while Relative layout feels the most "natural" if you're used to positioning things via CSS, for example (with absolute or relative positions) the situation you're describing here calls for either Linear or Table layout. Table layout is probably your best bet for anything "form" related. Your table elements (columns) should have a layout_span attribute that details how many columns to go across (it's sort of analog to colspan in HTML).
I'm not sure what specifically is going wrong in your RelativeLayout above, and I'm sure that with adequate trial and error you could get it to do roughly what you want, but I strongly advise you to use the right tools for the job.
LinearLayout is also a terrific tool (which you should remember can be nested indefinitely). Give your Layout a weightSum and then each item can have a layout_weight (they should add up to be the sum), while their layout_width should be 0dp (it's not intuitive, but that's how it works). That's also a terrific way to make things sit where they ought to.
Lastly the answer to the correct order in RelativeLayout is that the items are Z ordered from bottom to top, so the later an item appears in the sibling order, the higher its Z order is. Otherwise, their order is irrelevant.
I have a expandable list view consisting of varied sized textviews. The TextView size depends upon the contents in it. Now there are certain text which exceeds the screen width and the user is not able to view it.
I have tried HorizontolScrollView inside a ScrollView. It performs the scrolling but as my UI is a bit complex, it doesnot renders the other widgets in the view (like checkbox) properly.
Please suggest some good ideas to do the manual text scrolling.
Marquee is not a good suggestion. :)
Thanks in advance
Nested scroll view is a big 'no no' in android as there is no good way to determine which scroll has focus.
My solution would be to make an non-editable EditText. I would do something like this.
<EditText android:scrollHorizontally="true"
android:editable="false"
android:enabled="false"
android:layout_width="match_parent"
android:id="#+id/editText1"
android:layout_height="wrap_content" >
</EditText>
TextView seems to have a android:scrollHorizontally property as well but I have had no luck getting it to function.
Does any one know how to wrap text in TextView in Android platform. i.e if the text in textview exceed the screen length it should be displayed in the second line.
I have searched and tried the following:
android:scrollHorizontally="false",
android:inputType="textMultiLine",
android:singleLine="false"
But none work..
Can anyone suggest how can I do it.
Constraint Layout
<TextView
android:id="#+id/some_textview"
android:layout_width="0dp"
android:layout_height="wrap_content"
app:layout_constraintLeft_toLeftOf="#id/textview_above"
app:layout_constraintRight_toLeftOf="#id/button_to_right"/>
Ensure your layout width is zero
left / right constraints are defined
layout height of wrap_content allows expansion up/down.
Set android:maxLines="2" to prevent vertical expansion (2 is just an e.g.)
Ellipses are prob. a good idea with max lines android:ellipsize="end"
0dp width allows left/right constraints to determine how wide your widget is.
Setting left/right constraints sets the actual width of your widget, within which your text will wrap.
Constraint Layout docs
For me this issue only occurred on Android < 4.0
The combination of parameters I used were:
android:layout_weight="1"
android:ellipsize="none"
android:maxLines="100"
android:scrollHorizontally="false"
The maxLines count seemed to be the random final piece that made my TextView wrap.
For the case where the TextView is inside a TableLayout, the solution is to set android:shrinkColumns="1" on the TableLayout. (Replace 1 with the column number the TextView you want to wrap is in. (0-indexed))
AFAICT, no other attributes are needed on the TextView.
For other cases, see the other answers here.
FWIW, I had initially gotten it to sort of work with
<TextView
android:id="#+id/inventory_text"
android:layout_width="fill_parent"
android:layout_weight="1"
android:width="0dp"
but that resulted in some extra empty space at the bottom of the Dialog it was all in.
Use app:breakStrategy="simple" in AppCompatTextView, it will control over paragraph layout.
It has three constant values
balanced
high_quality
simple
Designing in your TextView xml
<android.support.v7.widget.AppCompatTextView
android:id="#+id/textquestion"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:scrollHorizontally="false"
android:text="Your Question Display Hear....Your Question Display Hear....Your Question Display Hear....Your Question Display Hear...."
android:textColor="#android:color/black"
android:textSize="20sp"
android:textStyle="bold"
app:breakStrategy="simple" />
If your current minimum api level is 23 or more then in Coding
yourtextview.setBreakStrategy(Layout.BREAK_STRATEGY_SIMPLE);
For more refrence refer this BreakStrategy
You must use 2 parameters :
android:ellipsize="none" : the text is not cut on textview width
android:scrollHorizontally="false" the text wraps on as many lines as necessary
This should fix your problem: android:layout_weight="1".
By setting android:maxEms to a given value together with android:layout_weight="1" will cause the TextView to wrap once it reaches the given length of the ems.
OK guys the truth is somewhere in the middle cause you have to see the issue from the parent's view and child's. The solution below works ONLY when spinner mode = dialog regardless of Android version (no problem there.. tested it in VD and DesireS with Android =>2.2) :
.Set you spinner's(the parent) mode like :
android:spinnerMode="dialog"
Set the textview's(child custom view) properties to :
android:layout_weight="1"
android:ellipsize="none"
android:maxLines="100"
android:scrollHorizontally="false"
I hope this works for you also.
In Android Studio 2.2.3 under the inputType property there is a property called textMultiLine. Selecting this option sorted out a similar problem for me. I hope that helps.
Just was working on a TextView inside a layout inside a RecyclerView. I had text getting cut off, ex, for Read this message, I saw: Read this. I tried setting android:maxLines="2" on the TextView, but nothing changed. However, android:lines="2" resulted in Read this on first line and message on the 2nd.
Try #Guykun's approach
android:layout_weight="1"
android:ellipsize="none"
android:maxLines="100"
android:scrollHorizontally="false"
Also, make sure that parents width is not set to wrap content. This is the thing that I was missing.
I had the same problem. Following change made it work -
android:layout_width="wrap_content"
The ellipsis, maxLines, or layout_weight - all didn't make any difference.
Note - The parent width is also set as wrap_content.
All you have to do is to set your textview width.
android:layout_width="60dp"
you can change the width to your choice. Just type long sentence to check if it working like this
android:text="i want to be among world class software engineer"
I am using Android 2.2 and my textview will automatically goto the next line if it exceeds the screen.
If you would like to have the text goto the next line before the end of the screen, just add in (just put in your own dp value). This will be useful if you have a picture on the right of the text.
android:layout_marginRight="52dp"
Strange enough - I created my TextView in Code and it wrapped - despite me not setting anything except standard stuff - but see for yourself:
LinearLayout.LayoutParams childParams = new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.WRAP_CONTENT);
childParams.setMargins(5, 5, 5, 5);
Label label = new Label(this);
label.setText("This is a testing label This is a testing label This is a testing label This is a testing labelThis is a testing label This is a testing label");
label.setLayoutParams(childParams);
As you can see from the params definition I am using a LinearLayout. The class Label simply extends TextView - not doing anything there except setting the font size and the font color.
When running it in the emulator (API Level 9) it automatically wraps the text across 3 lines.
Just set layout_with to a definate size, when the text fills the maximum width it will overflow to the next line causing a wrap effect.
<TextView
android:id="#+id/segmentText"
android:layout_marginTop="10dp"
android:layout_below="#+id/segmentHeader"
android:text="You have the option to record in one go or segments(if you swap options
you will loose your current recordings)"
android:layout_width="300dp"
android:layout_height="wrap_content"/>
The trick is with the textView width, try to make it dedicated number like:
<TextView
android:layout_width="300dp"
android:layout_height="wrap_content"/>
I've tried many solutions without any result, I've tried:
android:ellipsize="none"
android:scrollHorizontally="false"
the only one thing triggred the wrap option is the dedicated width
You need to add your TextView in a ScrollView with something like this :
<ScrollView android:id="#+id/SCROLL_VIEW"
android:layout_height="150px"
android:layout_width="fill_parent">
<TextView
android:id="#+id/TEXT_VIEW"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="This text view should act as header This text view should act as header This text view should act as header This text view should act as header This text view should act as header This text view should act as header This text view should act as header" />
</ScrollView>
