Android - Error in XML files

Question

So I am building a project but my R.Java got deleted somehow (reasons?) and it shows R can't b resolved into a variable,what to do now? Also no main.out.xml is there in my layout so no problems there.

Another problem is with my XML file in the two lines at bottom it shows these errors respectively:

1 - Error parsing XML no element found(No idea what this means.)

2 - XML document structure must start end end within the same entity.(Can't find an unclosed tag,help me!)

Here's my troubled XML file's code:

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

    <EditText
        android:id="@+id/editText1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:ems="10" >
    </EditText>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="56dp"
        android:background="@drawable/imgthing"
        android:orientation="horizontal"
        android:weightSum="100" >

        <TextView
            android:id="@+id/textView2"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_weight="50"
            android:gravity="center"
            android:text="TextView" />

        <TextView
            android:id="@+id/textView1"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_weight="50"
            android:gravity="center"
            android:text="TextView" />
    </LinearLayout>

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/imgthing"
        android:orientation="horizontal"
        android:weightSum="2" >

        <RadioGroup
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:orientation="vertical" >

            <RadioButton
                android:id="@+id/radioButton1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="RadioButton" />

            <RadioButton
                android:id="@+id/radioButton1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="RadioButton" />

            <RadioButton
                android:id="@+id/radioButton1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="RadioButton" />
        </RadioGroup>

        <RadioGroup
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:orientation="vertical" >

            <RadioButton
                android:id="@+id/radioButton1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="RadioButton" />

            <RadioButton
                android:id="@+id/radioButton1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="RadioButton" />

            <RadioButton
                android:id="@+id/radioButton1"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="RadioButton" />
        </RadioGroup>

        <TextView
            android:id="@+id/textView3"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:text="TextView" />

        <Button
            android:id="@+id/button1"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:text="Button" />
    </LinearLayout>
    </LinearLayout>

Also, when I view this in Graphical layout, then no radio buttons are visible in it. And if it matters, I have a white background in it. EDIT:The second error is gone, reposted the code, it has only the first error.

Answer 1

You forgot to close your parent layout, just close it and you will be ok!

Add at the end of the file

 </LinearLayout>

Hope this helps!
