There is only one position in an empty EditText, it's <a href="http://developer.android.com/reference/android/widget/EditText.html#setSelection%28int%29" rel="noreferrer"><code>setSelection(0)</code></a>.

Or did you mean you want to get focus to your <code>EditText</code> when your activity opens? In that case its <a href="http://developer.android.com/reference/android/view/View.html#requestFocus%28%29" rel="noreferrer"><code>requestFocus()</code></a>

If you want to place the cursor in a certain position on an EditText, you can use:

<pre><code>yourEditText.setSelection(position);
</code></pre>

Additionally, there is the possibility to set the initial and final position, so that you programmatically select some text, this way:

<pre><code>yourEditText.setSelection(startPosition, endPosition);
</code></pre>

Please note that setting the selection might be tricky since you can place the cursor before or after a character, the image below explains how to index works in this case:

<a href="https://i.stack.imgur.com/NG1nc.png" rel="noreferrer"><img src="https://i.stack.imgur.com/NG1nc.png" alt="enter image description here"></a>

So, if you want the cursor at the end of the text, just set it to <code>yourEditText.length()</code>.

blocks|key|248583|text|让editText2成为您第二个EditText视图，并将以下代码放入onResume()中|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|248584|editText2.setFocusableInTouchMode(true);

or put

as a reminder: if you are using <code>edittext.setSelection()</code> to set the cursor, and it is NOT working while setting up an <code>alertdialog</code> for example, make sure to set the <code>selection()</code> AFTER the dialog has been created

<h1>Set cursor to a row and column</h1>

You can use the following code to get the position in your EditText that corresponds to a certain row and column. You can then use <code>editText.setSelection(getIndexFromPos(row, column))</code> to set the cursor position.
The following calls to the method can be made:

<ul>
<li><code>getIndexFromPos(x, y)</code> Go to the column y of line x</li>
<li><code>getIndexFromPos(x, -1)</code> Go to the last column of line x</li>
<li><code>getIndexFromPos(-1, y)</code> Go to the column y of last line</li>
<li><code>getIndexFromPos(-1, -1)</code> Go to the last column of the last line</li>
</ul>

All line and column bounds are handled; Entering a column greater than the line's length will return position at the last column of the line. Entering a line greater than the EditText's line count will go to the last line. It should be reliable enough as it was heavily tested.

<pre><code>static final String LINE_SEPARATOR = System.getProperty("line.separator");

int getIndexFromPos(int line, int column) {
 int lineCount = getTrueLineCount();
 if (line &lt; 0) line = getLayout().getLineForOffset(getSelectionStart()); // No line, take current line
 if (line &gt;= lineCount) line = lineCount - 1; // Line out of bounds, take last line

 String content = getText().toString() + LINE_SEPARATOR;
 int currentLine = 0;
 for (int i = 0; i &lt; content.length(); i++) {
 if (currentLine == line) {
 int lineLength = content.substring(i, content.length()).indexOf(LINE_SEPARATOR);
 if (column &lt; 0 || column &gt; lineLength) return i + lineLength; // No column or column out of bounds, take last column
 else return i + column;
 }
 if (String.valueOf(content.charAt(i)).equals(LINE_SEPARATOR)) currentLine++;
 }
 return -1; // Should not happen
}

// Fast alternative to StringUtils.countMatches(getText().toString(), LINE_SEPARATOR) + 1
public int getTrueLineCount() {
 int count;
 String text = getText().toString();
 StringReader sr = new StringReader(text);
 LineNumberReader lnr = new LineNumberReader(sr);
 try {
 lnr.skip(Long.MAX_VALUE);
 count = lnr.getLineNumber() + 1;
 } catch (IOException e) {
 count = 0; // Should not happen
 }
 sr.close();
 return count;
}
</code></pre>

The question was already answered but I thought someone could want to do that instead.

It works by looping through each character, incrementing the line count every time it finds a line separator. When the line count equals the desired line, it returns the current index + the column, or the line end index if column is out of bounds. You can also reuse the <code>getTrueLineCount()</code> method, it returns a line count ignoring text wrapping, unlike <code>TextView.getLineCount()</code>.

How to resolve the cursor position issue which is automatically moving to the last position after formatting in US Mobile like (xxx) xxx-xxxx in Android.

<pre><code>private String oldText = "";
private int lastCursor;
private EditText mEtPhone;

@Override
 public void afterTextChanged(Editable s) {
String cleanString = AppUtil.cleanPhone(s.toString());

String format = cleanString.length() &lt; 11 ? cleanString.replaceFirst("(\\d{3})(\\d{3})(\\d+)", "($1) $2-$3") :
 cleanString.substring(0, 10).replaceFirst("(\\d{3})(\\d{3})(\\d+)", "($1) $2-$3");


boolean isDeleted = format.length() &lt; oldText.length();

 try {

 int cur = AppUtil.getPointer(lastCursor, isDeleted ? s.toString() : format, oldText, isDeleted);
 mEtPhone.setSelection(cur &gt; 0 ? cur : format.length());

 }catch (Exception e){
 e.printStackTrace();
 mEtPhone.setSelection(format.length());
 }

 mEtPhone.addTextChangedListener(this);

 }

 @Override
 public void beforeTextChanged(CharSequence s, int start, int count, int after) {

 oldText = s.toString();
 lastCursor = start;
 }
</code></pre>

Define the below method to any Activityclass in my case Activity name is AppUtil and access it globally

<pre><code>public static int getPointer(int index, String newString, String oldText, boolean isDeleted){

 int diff = Math.abs(newString.length() - oldText.length());

 return diff &gt; 1 ? isDeleted ? index - diff : index + diff : isDeleted ? index : index + 1;
 }

public static String cleanPhone(String phone){

 if(TextUtils.isEmpty(phone))
 return "";

 StringBuilder sb = new StringBuilder();
 for(char c : phone.toCharArray()){
 if(Character.isDigit(c))
 sb.append(c);
 }
 return sb.toString();
 }
</code></pre>

And if you want to set any specific position

<pre><code>edittext.setSelection(position);
</code></pre>

I believe the most simple way to do this is just use padding.

Say in your xml's edittext section, add 
 android:paddingLeft="100dp"
This will move your start position of cursor 100dp right from left end.

Same way, you can use
 android:paddingRight="100dp"
This will move your end position of cursor 100dp left from right end.

For more detail, check this article on my blog: <a href="http://www.arthurwang.net/arthur-wang/android/android-setting-cursor-starting-and-ending-position-in-edittext-widget/" rel="nofollow">Android: Setting Cursor Starting and Ending Position in EditText Widget</a>
