I have some problems wrapping text in my application.

Here is my layout :

<GridLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:columnCount="2"
    android:orientation="horizontal"
    android:rowCount="2" >

    <ImageView
        android:id="@+id/img"
        android:layout_width="150dp"
        android:layout_height="225dp"
        android:layout_gravity="left|top"
        android:layout_column="0"
        android:layout_rowSpan="2"
        android:contentDescription="@string/imgdesc" />

    <TextView
        android:id="@+id/tvName"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="left"
        android:layout_column="1"
        android:layout_marginLeft="20dp"
        android:layout_row="0"
        android:textAppearance="?android:attr/textAppearanceLarge" />

    <TextView
        android:id="@+id/tvDescription"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_column="1"
        android:layout_gravity="fill_horizontal"
        android:layout_marginLeft="20dp"
        android:layout_marginTop="10dp"
        android:layout_row="1"/>

</GridLayout>

And here is the result :

As you can see, a part of the text is out the screen and I don't really know how to fix it.

Try to use LinearLayout for your design instead of GridLayout :

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <ImageView
        android:id="@+id/img"
        android:layout_width="150dp"
        android:layout_height="225dp"
        android:contentDescription="@string/imgdesc"/>

    <LinearLayout
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:padding="5dp"
        android:orientation="vertical">
        <TextView
            android:id="@+id/tvName"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:singleLine="true"
            android:textAppearance="?android:attr/textAppearanceLarge" />

        <TextView
            android:id="@+id/tvDescription"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginTop="10dp"/>
    </LinearLayout>
</LinearLayout>
