I create EditText programmatically.
Following is my code:
mEditText = new EditText(mMainActivity);
mEditText.setVisibility(View.INVISIBLE);
mEditText.setTextSize(8);
mEditText.setSingleLine();
mEditText.setMaxLines(1);
mEditText.setLines(1);
mEditText.setVerticalScrollBarEnabled(false);
What I set above seems completely useless...Please help me.
You can try setMovementMethod() It will disable the EditText text scrolling. But you have to manage text size.
eText.setMovementMethod(null);
Hope it will help you...
Set below properties:
mEditText.setSingleLine(true);
mEditText.setHorizontallyScrolling(true);
It will work.
What input type do you want?
editText.setInputType(InputType.TYPE_**);
if email/phone you do not even need the
editText.setLines(1);
editText.setMaxLines(1);
Also note your method
editText.setSingleLine(false);
May be changing the values on your maxLines and Lines methods.
I am trying to add an image into my app with java so I googled how to do this and seen I had to add
Context mContext;
Drawable myImage = mContext.getDrawable(R.drawable.my_image);
(That was all of the code they said I had to add) But when I run it I don't see my image I set to it. So how I would be able to show the image I set to it?
For a image to be displayed, you need to give a view for that . ie - ImageView
Add a ImageView in your main-layout.
Initialize that ImageView in the on create of your activity like
ImageView appImage = findViewById(R.id.your_image_View_id);
3.Then set an image to the image view like
appImage.setImageResource(R.drawable.your_image);
Hope this helps.
You just initialize the imageview from layout like below,
ImageView appImage = findViewById(R.id.your_image_View_id);
appImage.setImageDrawable(ContextCompat.getDrawable(getActivity(),R.drawable.ic_downarrow));
With new android API 22 getResources().getDrawable() is now deprecated. So now the best approach is to use only getDrawable() is using ContextCompat
Please follow the steps:
Step1: In your main_layout.xml, add an <ImageView ... tag give an id, let's say id is "imageView"
Step2: In your MainActivity.class onCreate() method, Initialize that ImageView as:
ImageView image = findViewById(R.id.imageView)
then,
Step3: assign your drawable as:
im.setImageDrawable(ContextCompat.getDrawable(MainActivity.this, R.drawable.your_image_drawable));
If you are using a fragment, use:
im.setImageDrawable(ContextCompat.getDrawable(getActivity(), R.drawable.your_image_drawable));
Hope it helps. Please update if it does.
ImageView appImage = findViewById(R.id.your_image_View_id);
In activity simply use setImageResource
appImage.setImageResource(R.drawable.ic_avatar);
input.replace("&", "&").replace("<", "<").replace(">", ">").replace(""", "\"");
im using this line of code as a sudo htmlspecialchars converter. with my application, it doesnt need to be too elaborate.
for some reason the above code does not replace("&", "&"), it doesnt seem to do anything.
any advice?
input = input.replaceAll("[^\\x20-\\x7e]", "");
i also tried this.
In android there is one class Html inside android.text.Html which you can use like this as below:
Html.fromHtml(any_html_text);
But this function will return Spanned object so use
Spanned spn=Html.fromHtml(any_html_text);
You can set this spanned text to any button or textview text Hope it will help you.
See this link also for your reference.
Instead of doing this manually, check out the Html class. Calling Html.fromHtml() should do the trick.
Trying to escape/unescape html by replacing strings yourself you might introduce security issues in your application (depending on what it does with the output). Either use Html.FromHtml or from Apache libs org.apache.commons.lang.StringEscapeUtils.unescapeHtml
This does the work -
public String cleanString(String dirty) {
return Html.fromHtml(dirty).toString();
}
I'm trying to use a font I found on the internet, but the problem is that I get an FC with "native typeface cannot be made".
Here is the code in the getView of my ListVIew:
holder.tv_SuraName =(TextView)convertView.findViewById(R.id.Start_Name);
holder.tv_SuraName.setTypeface(Typeface.createFromAsset(mContext.getAssets(), "suralist_font.ttf"));
Can anyone tell me why can I use the custom rom? You can get it HERE .. the file is .ttf
My problem was incorrect placement of the assets folder.
When using Android Studio the assets folder should be inside of the source sets e.g.
src/main/assets/
Found in this answer
The font file is either corrupt or unsupported for some reason. You can drop it on the SD card and load it from file, to make sure it's not a problem with your assets.
There are basically 4 things that can cause this:
You use the wrong extension
You have to place the fonts in the assets folder and not inside assets/fonts/
You misspelled the fonts
The fonts need to be lowercase (in my case the solution was to rename MyFont.ttf to myfont.ttf, strange)
Double check the extension isn't in caps, ie. suralist_font.TTF
Fonts often come seem to come that way and it might be overlooked.
I had this same problem, I created mine in assets>fonts>whatever.ttf and was getting the same error. I added the fonts extension (fonts/whatever.ttf) and it fixed the problem in every case.
holder.tv_SuraName =(TextView)convertView.findViewById(R.id.Start_Name);
holder.tv_SuraName.setTypeface(Typeface.createFromAsset(mContext.getAssets(), "fonts/suralist_font.ttf"));
Rather old thread, but I want to add one more reason this can happen: You have to set the content view before calling typeface. See example below
Does not work:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView title = (TextView)findViewById(R.id.tvTitle);
Typeface font = Typeface.createFromAsset(this.getAssets(), "fonts/whatever.ttf");
title.setTypeface(font);
setContentView(R.layout.main);
}
Does work!
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main); // <-- call before typeface
TextView title = (TextView)findViewById(R.id.tvTitle);
Typeface font = Typeface.createFromAsset(this.getAssets(), "fonts/whatever.ttf");
title.setTypeface(font);
}
I am using android studio, in my case problem was with the path of assets folder, in Eclipse path for assets folder is res/assets/ but in Android Studio its src/main/assets/
So, i just move my font file to this path and finally problem solved.
Either your font file is corrupt else you making some mistake in spelling while calling your file name. I had same issue, it was because file name specified in asset folder was
roboto_black.ttf
and while declaring in java file, i have been spelling it as:
roboto_blak.ttf
If your .ttf files are in asset folder,then use:
Typeface type_bold = Typeface.createFromAsset(getAssets(), "roboto_black.ttf");
Else if it is in fonts folder, then use:
type_bold = Typeface.createFromAsset(getAssets(), "fonts/roboto_black.ttf");
Hope it helps!
Hope this will help
Typeface.createFromAsset leaks asset stream: http://code.google.com/p/android/issues/detail?id=9904
As CommonsWare states in this answer
I would guess that there is a problem with the font itself. That error
will be triggered when native code in the OS attempts to load the
typeface.
Anyway try this one:
holder.tv_SuraName = (TextView)convertView.findViewById(R.id.Start_Name);
Typeface Font = Typeface.createFromAsset(this.getAssets(),"suralist_font.ttf");
holder.tv_SuraName.setTypeface(Font);
I had the same problem with COMIC.TTF from comic sans ms of Windows.
Since the original file I placed in assets/fonts folder was in uppercase as spelt above, I had to type it exactly in uppercase.
Typeface.createFromAsset(getAssets(), "fonts/COMIC.TTF");
it turns out the problem was caused by the lower case:
Typeface.createFromAsset(getAssets(), "fonts/comic.ttf");
Please note that this is due to either a corrupt file or you have placed the file in the wrong folder.
According to Android documentation here
main/assets/
This is empty. You can use it to store raw asset files. Files that you save here are compiled into an .apk file as-is, and the original filename is preserved. You can navigate this directory in the same way as a typical file system using URIs and read files as a stream of bytes using the AssetManager. For example, this is a good location for textures and game data.
Therefore your folder structure should be yourmodule/main/assets (e.g. a***pp/main/assets*** )
What worked for me was first changing my font name to only lower case and underscore: from Amatic-Sc.ttf to amatic_sc.ttf.
Then in the set.TypeFace method change assets/fonts/amatic_sc.ttf to just fonts/amatic_sc.ttf.
I've been debugging forever on this error in Android Studio. Clean and rebuilding the project after adding the fonts to the assets directory fixed the issue for me.
Just did a build --> clean and it started rendering .
I had same issue which happened on Android 4.0.3-4.0.4 (100% reproducible on emulator IceCreamSandwich mips 4.0.3).
The problem was that TTF fonts, that I had, were not correct, despite almost all Android versions were able to load those TTF font. So I used https://cloudconvert.com/woff-to-ttf (since I had woff files as well) to make new TTF fonts, which solved my problem.
Im having some trouble with setting textview to invisible/visible.
basicly i want this to happen when an on/off button has been clicked.
what i did is kind of like
textview.setVisibility(TextView.VISIBLE);
textview.setVisibility(TextView.INVISIBLE);
when i try executing this the emultor says that the app has stopped unexcpetedly
Are you building this from XML or programmatically?
I would make it with an XML file then when the Activity runs change the property. Be sure to use setContentView(R.layout.main); before you try to get the TextView with findViewById(...).
Call .setVisibility(View.GONE); on the TextView to hide it.
Call .setVisibility(View.VISIBLE); to on the TextView to show it.
I have an example that does something like this. You can see the code here: https://github.com/ethankhall/Morse-Messenger/blob/master/src/com/kopysoft/MorseMessenger/Translate.java
Without more code or a stack trace, it's hard to say, but it sounds like you haven't initialized the text view. Here's how to do it:
TextView myTextView = (TextView) findViewById(R.id.tv_text);
Where 'tv_text' is the id of the textview as defined in the xml layout file.
Hope that helped!
