I have an edit text inside a textinputlayout. I am trying to set the mandatory field symbol (red color asterisk) to the edittext. I have set the hint to the edit text. My code is as below. <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:layout_marginLeft="16dp" android:layout_marginTop="16dp" android:orientation="horizontal"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text=" * " android:layout_gravity="center_vertical" android:textColor="#ff0000" android:textSize="15sp" /> <android.support.design

Here's my code. xml <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_gravity="center" android:background="@android:color/transparent" android:gravity="center" android:orientation="vertical" > <TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text=

I have an EditText that has an inputType of number . While the user is typing, I want to comma-separate the numbers. Here's a little illustration: 123 would be represented as 123 1234 would be represented as 1,234 12345 would be represented as 12,345 ...and so on. I tried adding a comma with TextWatcher as shown below: EditText edittext = findViewById(R.id.cashGiven); edittext.addTextChangedListener(new TextWatcher(){ @Override public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) { } @Override public void onTextChanged(CharSequence charSequence, int i, int i1, int i2

How can I count the number of lines in an EditText? Basically in my app I have line numbers and I wanted to make them update on textchange (I already have the textchangelistener set up). Is this possible? :( Thanks, Alex! Whiler Lines can be differents: Visible lines: Wrapped text count as a new line... List item: Only lines with \r, \n, \r\n First case (the easiest): int nbLines = editText.getLineCount(); Second case: int nbLines = 0; StringReader sr = new StringReader(editText.getText().toString()); LineNumberReader lnr = new LineNumberReader(sr); try { while (lnr.readLine() != null){}

I'm trying to implement android:scrollbars="vertical" in XML by Java code. I've tried method setVerticalScrollBarEnabled(true) but it doesn't work. Anyone can give me a suggestion? Thanks in advance. you can use EditText ed=new EditText(context); ed.setScroller(new Scroller(context)); ed.setVerticalScrollBarEnabled(true); this will give the scroll option for the edit text but it won't show the scroll bar. 来源： https://stackoverflow.com/questions/8417454/how-to-enable-vertical-scrollbar-of-an-edittext-programmatically

I am trying to set smaller height of EditText but still have not managed it. Here is my source: <EditText android:layout_width="150dp" android:layout_height="20dp" android:singleLine="true" android:textSize="10dp" /> This code cuts out text and a white rectangular shape appears around EditText control. I have also tried maxHeight/minHeight properties, but did not worked either. If anybody have solved this issue, please help. Or is this is the bug in the android? I can not even resize Spinner, same happens as with EditText. Thanks Irfan You are probably seeing bizarre orange rectangular shapes

I have an edittext. In that edittext user enters some text. when user hits on space key, i need to perform some action. how can i do it. Thanks in advance. jcw To do something when the user presses the space key you use the following - if((event.getAction()==KeyEvent.ACTION_DOWN)&&(key == KeyEvent.KEYCODE_SPACE)){ //put your code for whatever you what to do when the user presses space here } } Problems intercepting space key in EditText If you have multiple edittexts, in the above code put if (edittext.hasFocus()){ //do something for particular edit text } I think I know why your edittext is
