Android Edit Text - Cursor stays at the starting p

问题:

I am using an Edit Text in my project.

The problem is that whenever I type anything into the text box, it shows up, but the cursor does not move from its starting position at all, regardless of how many characters I type. Also I am not able to move by clicking to any particular character in the text box.

My xml file for containing the edit text is like this

<EditText
        android:id="@+id/xEt"
        android:layout_width="fill_parent"
        android:layout_height="295dp"
        android:layout_alignParentLeft="true"
        android:ems="10"
        android:focusableInTouchMode="true" 
android:focusable="true" >

The xml file is:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

set these properties to your XML file

  <YourLayout
     xmlns:android="http://schemas.android.com/apk/res/android"
     android:focusable="true" 
     android:focusableInTouchMode="true">

  <EditText
    android:id="@+id/xEt"
    android:layout_width="fill_parent"
    android:layout_height="295dp"
    android:layout_alignParentLeft="true"
    android:ems="10"
    android:clickable="true"
    android:cursorVisible="true"/> 

</YourLayout>

Try this. and put this in your java code.

 EditText et = (EditText)findViewById(R.id.xEt);
 et.setSelection(et.getText().length());

I am using this workaround for this problem, If characters are in English or digit characters then change EditText gravity to left else in another Language in my case it's in Arabic then will change gravity to left and the cursor will move in it's right way according to each language:

        editText.addTextChangedListener(new TextWatcher() {

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {
                if(s.length() > 0){
                    char c = s.charAt(0);
                     // characters are Enlgish or digits.
                    if ((c >= 'a' && c <= 'z') || (c >= 'A' && c <= 'Z') || Character.isDigit(c)) {
                        editText.setGravity(Gravity.LEFT);
                    }else {
                        editText.setGravity(Gravity.RIGHT);


                    }
                } 
            }

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

            }

            @Override
            public void afterTextChanged(Editable s) {

            }
        });

回答3:

Are you binding you view to a model? i.e. Do you have an MVVM setup?

If you do, make sure you do not have any cyclical update especially for a two-way binding i.e. if user types a character, you update your model which will in turn update the EditText control and repeat.

So depending on your Editext control properties, each time the model change updates it, it could have the cursor reset to the start position.

If this is the case, a simple equality check between the model value and the EditText text value before you update it from the model should fix the issue.

if (txtEdit.text != modelValue)
{
    txtEdit.text = modelValue;
}

It may be a bit too late to answer this question. But even i faced the same problem by using custom Keyboard. The problem was solved for me too after adding the following line in the XML file for every edittext

android:imeOptions="flagNoExtractUi"

android:inputType="textNoSuggestions"

Like this

<Editext                
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:paddingLeft="2dp" 
 android:inputType="textNoSuggestions"
 android:imeOptions="flagNoExtractUi"/>

I have seen a lot of people searching for this so i have posted to the one relevant to my problem.
