<EditText 
    android:id="@+id/searchbox"  
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:lines="1"
    android:scrollHorizontally="true"

    android:drawableLeft="@drawable/folder_full"
    android:drawableRight="@drawable/search"
    android:paddingLeft="15dp"
    android:hint="search...">
</EditText>

I want to make the above EditText to have only single line. Even if the user presses "enter" the cursor should not get down to the second line. Can anybody help me doing that?

Answer 1

android:maxLines="1"
android:inputType="text"

Add the above code to have a single line in EditText tag in your layout.

android:singleLine="true" is deprecated

This constant was deprecated in API level 3.

This attribute is deprecated. Use maxLines instead to change the layout of a static text, and use the textMultiLine flag in the inputType attribute instead for editable text views (if both singleLine and inputType are supplied, the inputType flags will override the value of singleLine).

Answer 2

This will work for the EditText:

android:inputType="text"

Then I would set a max length for the input text:

android:maxLines="1"

Those are the 2 that are needed now.

Answer 3

The @Aleks G OnKeyListener() works really well, but I ran it from MainActivity and so had to modify it slightly:

EditText searchBox = (EditText) findViewById(R.id.searchbox);
searchBox.setOnKeyListener(new OnKeyListener() {

    public boolean onKey(View v, int keyCode, KeyEvent event) {

        if (event.getAction() == KeyEvent.ACTION_DOWN && keyCode == KeyEvent.KEYCODE_ENTER) {
            //if the enter key was pressed, then hide the keyboard and do whatever needs doing.
            InputMethodManager imm = (InputMethodManager) MainActivity.this.getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(searchBox.getApplicationWindowToken(), 0);

            //do what you need on your enter key press here

            return true;
        }

        return false;
    }
});

I hope this helps anyone trying to do the same.

Answer 4

I have done this in the past with android:singleLine="true" and then adding a listener for the "enter" key:

((EditText)this.findViewById(R.id.mytext)).setOnKeyListener(new OnKeyListener() {

    public boolean onKey(View v, int keyCode, KeyEvent event) {

        if (event.getAction() == KeyEvent.ACTION_DOWN && keyCode == KeyEvent.KEYCODE_ENTER) {
            //if the enter key was pressed, then hide the keyboard and do whatever needs doing.
            InputMethodManager imm = (InputMethodManager)context.getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(getApplicationWindowToken(), 0);

            //do what you need on your enter key press here

            return true;
        }

        return false;
    }
});

Answer 5

Use Below Code instead of your code

<EditText 
    android:id="@+id/searchbox"  
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:maxLines="1"
    android:inputType="text"
    android:scrollHorizontally="true"
    android:ellipsize="end"
    android:layout_weight="1"
    android:layout_marginTop="2dp"
    android:drawablePadding="10dp"
    android:background="@drawable/edittext"
    android:drawableLeft="@drawable/folder_full"
    android:drawableRight="@drawable/search"
    android:paddingLeft="15dp"
    android:hint="search..."/>

Answer 6

android:singleLine is now deprecated. From the documentation:

This constant was deprecated in API level 3.

This attribute is deprecated. Use maxLines instead to change the layout of a static text, and use the textMultiLine flag in the inputType attribute instead for editable text views (if both singleLine and inputType are supplied, the inputType flags will override the value of singleLine).

So you could just set android:inputType="textEmailSubject" or any other value that matches the content of the field.
