如果我们直接使用editText.setSelection(position)，有时编辑文本光标不会出现在特定位置;． 那样的话，你可以试试

editText.post(new Runnable() {
                @Override
                public void run() {
                    editText.setSelection(string.length());
                }
            });

Edittext中的setSelection(int index)方法应该允许您这样做。

我相信最简单的方法就是使用填充。

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

同理，你可以用 android: paddingRight = " 100 dp” 这将把你的光标的结束位置从右端向左移动100dp。

要了解更多细节，请查看我博客上的这篇文章:Android:在EditText Widget中设置光标的起始和结束位置

如果要在EditText中设置光标位置?试试下面的代码

EditText rename;
 String title = "title_goes_here";
 int counts = (int) title.length();
 rename.setSelection(counts);
 rename.setText(title);

提醒一下:如果你正在使用edittext.setSelection()来设置光标，并且它在设置alertdialog时不起作用，请确保在对话框创建后设置selection()

例子:

AlertDialog dialog = builder.show();
input.setSelection(x,y);

如何解决在US Mobile中格式化后自动移动到最后一个位置的光标位置问题，如Android中的(xxx) xxx-xxxx。

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() < 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() < oldText.length();

        try {

            int cur = AppUtil.getPointer(lastCursor, isDeleted ? s.toString() : format, oldText, isDeleted);
            mEtPhone.setSelection(cur > 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;
    }

在我的例子中，将下面的方法定义为任何Activityclass，活动名称为AppUtil并全局访问它

public static int getPointer(int index, String newString, String oldText, boolean isDeleted){

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

        return diff > 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();
    }

如果你想设置一个特定的位置

edittext.setSelection(position);
