    I want to display a block character “ALT-219” in a TextView. It isn’t easy to search Google or stackoverflow for this as block means so many other things but I tried. I experimented with saving the file as a UTF-8 and my entire project crashed in some unexplainable way, I went to backups, that crashed in even worse ways. I finally backed out of what I did and rebuilt so I am back to scratch but I am not inclined to experiment without asking for help.What I am really trying to do is create a ps

    Basically in my app I have a ‘graph’ (from holographlibrary). That is irrelevant though, we’ll just call it a textview.So in my layout-small files I do not have set textview that I have in my layout-normal files. So if I run the app on a small screen, when the code tries to find it, it can’t and the app crashes. Is there some easy way to only call findviewbyid if it is the the layout file, and then stop the other code involving it from running.

    I’m having a hard time reseting the maxLines attribute of a TextView programmatically.Just tried setting to 0 and it doesn’t work. -1 crashes the application. I could use a simpler workaround and set the maxLines to 5000 but I don’t want to do that.Any ideas how to do that?UPDATEDWell, I’ve found one problem.. I’ve set the Ellipsize as well… I’m just going to use the following workaround:TextView questionDetail = (TextView) mQuestionDetailHeader.findViewById(R.id.desc);questionDetail.setText(m

    I’ve got a ExpandableListView which when I click to expand the child it throws a “Id not found” error when I try and update the Text on a TextView in the child Layout. If I comment this section out it works fine. I’ve based my project off examples I’ve found round the place. Can anyone spot where I’ve gone wrong?Here’s the child layout:<?xml version=”1.0″ encoding=”utf-8″?> <LinearLayout xmlns:android=”http://schemas.android.com/apk/res/android”android:layout_width=”match_parent”android

    Im trying to develop a text adventure for android. Already found a subtle way to change ‘pages’ without creating new Activity.Now I was trying to include permanent int values on each of my layouts that would get updated immediately when changed.I.e. gold/health values. Depending on the choice of player ingame, it would: – change the layout to the corresponding page – change int value of Gold +10, health -1I developed this code in the mainactivity class:package com.example.textadventure;import an

    android android-edittext android-textview android-spinner
    I’m creating an Android app that takes in basic user input (from keyboard) via an EditText widget. I’m getting some stubborn behavior from a line I call within the OnItemSelected function for my Activity’s Spinners. I am gathering the double value from my EditText (doing appropriate type conversions), and the app crashes. My logcat’s report that the error is that “” is not an appropriate double value, which means that this function is being called while the EditText is still empty (I’m guessing

    First time poster!I am new to Android development and have been following Google’s HelloView tutorials without problems… until the HelloGridView tutorial. For some reason I cannot get any images to display, only a black background. I originally followed this tutorial:http://developer.android.com/resources/tutorials/views/hello-gridview.htmlbut moved on to this nearly identical one:http://developer.android.com/guide/tutorials/views/hello-gridview.htmlin order to eliminate some added complexity

    I am trying to use fragments to build my first proper Android App. I have a main xml. which consists of two vertical fragments, the top fragments consists of just two TextViews. The first of these contains static text and the second contains a value which I will eventually be getting dynamically from SQL.If i put this is my MainActivity.java then it happily updates the value of the TextView in my first Fragment:public void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);

    android android-textview fontsize multiline
    i’ve looked for solutions of auto-fitting the font of the textView according to its size , and found many , but none support multi-lines and does it correctly (without truncating the text and also respect the gravity values) .has anyone else conducted a solution as such?is it also possible to set the constraint of how to find the optimal number of lines ? maybe according to max font size or max characters numbers per line?
