How to fit my design to all devices?
<p>Hi I am developing a app in which alphabets are not fitting for every device. For HCL ME tablet my design won't fit. For samsung it is working. MY XML file is:</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:layout_weight="2" android:orientation="vertical"&gt;

    &lt;LinearLayout android:id="@+id/linearLayout1" android:layout_height="match_parent" 
    android:orientation="horizontal" android:layout_width="match_parent" 
    android:layout_weight="1"&gt;

        &lt;LinearLayout android:id="@+id/linearLayout1" android:layout_height="match_parent"  
        android:orientation="vertical" android:layout_width="match_parent" 
        android:layout_weight="1"&gt;
            &lt;TextView  android:id="@+id/letter1" android:gravity="center" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_weight="1"&gt;&lt;/TextView&gt;
            &lt;TextView  android:id="@+id/letter2" android:gravity="center" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_margin="10dip"&gt;&lt;/TextView&gt;
            &lt;TextView  android:id="@+id/letter3" android:gravity="center" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_margin="10dip"&gt;&lt;/TextView&gt;
        &lt;/LinearLayout&gt;

        &lt;LinearLayout android:id="@+id/linearLayout1" android:layout_height="match_parent"  
        android:gravity="center"
        android:orientation="horizontal" android:layout_width="match_parent" 
        android:layout_weight="1"&gt;
            &lt;ImageView android:id="@+id/imag"  
            android:gravity="center"
            android:scaleType = "fitCenter"
            android:layout_height="fill_parent" 
            android:layout_width="fill_parent"
             android:layout_gravity="center"&gt;
        &lt;/ImageView&gt;

        &lt;/LinearLayout&gt;

    &lt;/LinearLayout&gt;


        &lt;LinearLayout android:layout_gravity="bottom" 
        android:id="@+id/linearLayout2" 
        android:layout_height="wrap_content" android:orientation="horizontal" android:layout_width="match_parent"&gt;
            &lt;Button android:id="@+id/previous" android:layout_width="wrap_content" android:layout_weight="1" android:text="Previous" android:layout_height="wrap_content" &gt;&lt;/Button&gt;
            &lt;Button android:id="@+id/practice" android:layout_width="wrap_content" android:layout_weight="1" android:text="Practice" android:layout_height="wrap_content" android:onClick="onClick"&gt;&lt;/Button&gt;
            &lt;Button android:id="@+id/home" android:layout_width="wrap_content" android:layout_weight="1" android:text="Home" android:layout_height="wrap_content"&gt;&lt;/Button&gt;
            &lt;Button android:id="@+id/spell" android:layout_width="wrap_content" android:layout_weight="1" android:text="Spell" android:layout_height="wrap_content" android:onClick="Content"&gt;&lt;/Button&gt;
            &lt;Button android:id="@+id/next" android:layout_width="wrap_content" android:layout_weight="1" android:text="Next" android:layout_height="wrap_content" android:onClick="Content"&gt;&lt;/Button&gt;


        &lt;/LinearLayout&gt;

&lt;/LinearLayout&gt;
