I want to have padding in EditText so that the text is not in the most left position of EditText.

Tried to use this but doesn't work.

<inset android:insetLeft="6dip"/>

How can I add padding in EditText drawable? I don't want to put it in every EditText in my XML layout.

Answer 1

For adding the padding in EditText,you need to create the custom editText, override the onLayout() method and set the padding in that method such as

public class CustomEditText extends EditText
{
  public CustomEditText(Context context) 
  {
     super(context);
  }

  public CustomEditText(Context context,AttributeSet attrs) 
  {
     super(context, attrs);
  }

  public CustomEditText(Context context,AttributeSet  attrs, int defStyle) 
   {
     super(context, attrs, defStyle);
   }

@Override
protected void onLayout(boolean changed, int left, int top, int right, int bottom) {
    // set the padding here
    this.setPadding(20,20,20, 20);
    super.onLayout(changed, left, top, right, bottom);
}
}

I found this .. Hope it will help. This is the logic . you need to customize it. This is main Layout where you can add edittext

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="#eee">

    <!-- Input Group -->
    <EditText style="@style/Widget.Group.Top" />
    <EditText style="@style/Widget.Group" />
    <EditText style="@style/Widget.Group.Bottom" />

    <!-- Single item -->
    <EditText style="@style/Widget.Group.Single" />

</LinearLayout>

and add some style in you style file like this

<style name="Widget.Group" parent="@android:style/Widget">
        <item name="android:layout_width">match_parent</item>
        <item name="android:layout_height">46dp</item>
        <item name="android:layout_marginLeft">10dp</item>
        <item name="android:layout_marginRight">10dp</item>
        <item name="android:layout_marginTop">-1dp</item> <!-- Ensures we don't get a 2 dp top stroke -->
        <item name="android:padding">4dp</item>
        <!--<item name="android:background">@drawable/bg_input_group</item>-->
    </style>

    <style name="Widget.Group.Top">
        <item name="android:layout_marginTop">10dp</item>
        <!--<item name="android:background">@drawable/bg_input_group_top</item>-->
    </style>

    <style name="Widget.Group.Bottom">

        <item name="android:layout_marginTop">20dp</item>
        <!--<item name="android:background">@drawable/bg_input_group_bottom</item>-->
    </style>

    <style name="Widget.Group.Single" parent="Widget.Group.Top">
        <!--<item name="android:background">@drawable/bg_input_group_single</item>-->
    </style>
