Question

I just faced to a weired problem in Android. That is, I created my project in eclipse using default settings. Eclipse has applied “Android 2.3.3 (API10) as the “Build SDK” and “API8:Android 2.2 (Froyo)” as the “Minimum required SDK.

However, I asked a question here and they have asked me to use the attribute “android:layout_toRightOf” but that attribute wasn’t available!! Following were the attributes available which starts with android:layout_, they are width, height, weight, gravity, margin, marginLeft, marginTop, marginRight and marginBottom.

However, then I opened another project with “Android 2.3.3 (API10) as the “Build SDK” and the same as the “Minimum required SDK”. Now, those attributes are there!!

Why is this? Do I have to select the same API as the build sdk and minimum required sdk? Please help!

EDIT

Following code has those attributes, which didn’t appear when I am trying to use at the first time

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent"

<TextView 
    android:id="@+id/firstTextView"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/firstNumber"
    android:alignParentLeft="true"
    android:alignParentTop="true"
    />

<EditText 
    android:id="@+id/firstNumberTxt"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:toRightOf="@+id/firstTextView"
    android:marginLeft=30dp 
    />

<TextView

         <RadioButton

             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:text="@string/sum"
             />

         <RadioButton 
             android:id="@+id/min"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:text="@string/min"
             />

         <RadioButton 
             android:id="@+id/max"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:text="@string/max"
             />

         <RadioButton 
             android:id="@+id/dev"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:text="@string/dev"
             />
     </RadioGroup>

Answer 1

Are you using a RelativeLayout? toRightOf is only available in that kind of layouts!
