Question

I want to show an image in a Toast in Android. In my layout.xml, I have defined a LinearLayout ‘svllid’, that contains a textview and a tablelayout, like so:

<?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="#CCCCCC"
    android:weightSum="1" android:id="@+id/llid">
    <EditText  
        android:id="@+id/cpuText"  
        android:hint="Enter cpu" 
        android:layout_height="wrap_content"   
        android:layout_width="fill_parent">  
    </EditText>
    <EditText  
        android:id="@+id/ramText"  
        android:hint="Enter ram" 
        android:layout_height="wrap_content"    
        android:layout_width="fill_parent">  
    </EditText> 
    <EditText  
        android:id="@+id/bandwidthText"  
        android:hint="Enter bandwidth" 
        android:layout_height="wrap_content"    
        android:layout_width="fill_parent">  
    </EditText> 
    <Button  
        android:id="@+id/imageRequestButton"  
        android:layout_height="wrap_content"  
        android:text="Download"   
        android:layout_width="fill_parent" android:onClick="sendImageRequest">  
    </Button>       
    <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="#00FF00"
        android:weightSum="1" android:id="@+id/svllid">

            android:gravity="center_horizontal"
            android:background="#000000">
        </TextView> 
        <TableLayout
            android:paddingBottom="3pt"  
            android:background="#0000FF"
            android:layout_width="fill_parent" 
            xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="wrap_content">
            <TableRow>
                <TextView
                    android:paddingLeft="3pt" 
                    android:paddingTop="3pt" 
                    android:text="Image Name"
                    android:layout_width="150px"
                    android:layout_height="wrap_content" 
                    android:textColor="#FFFFFF"/>
                <TextView
                    android:paddingLeft="3pt" 
                    android:text="blah.png"
                    android:textColor="#FFFFFF"
                    android:layout_width="315px"
                    android:layout_height="wrap_content" android:id="@+id/imageName"/>          
            </TableRow>
            <TableRow>
                <TextView
                    android:paddingLeft="3pt" 
                    android:text="Size"
                    android:layout_width="150px"
                    android:layout_height="wrap_content" 
                    android:textColor="#FFFFFF"/>
                <TextView
                    android:paddingLeft="3pt" 
                    android:text="155kb"
                    android:textColor="#FFFFFF"
                    android:layout_width="300px"
                    android:layout_height="wrap_content" android:id="@+id/imageSize"/>          
            </TableRow> 
            <TableRow>
                <TextView
                    android:paddingLeft="3pt" 
                    android:text="Dimensions"
                    android:layout_width="150px"
                    android:layout_height="wrap_content" 
                    android:textColor="#FFFFFF"/>
                <TextView
                    android:paddingLeft="3pt" 
                    android:text="250 X 150px"
                    android:textColor="#FFFFFF"
                    android:layout_width="300px"
                    android:layout_height="wrap_content" android:id="@+id/imageDimension"/>         
            </TableRow>                         
        </TableLayout>                                          
    </LinearLayout>
</LinearLayout>

I want to show the LinearLayout with id ‘svllid’ in a Toast and show the toast from my activity code.

Now, in the actual android code, I first call

setContentView(R.layout.main); 

Subsequently, I read an image from a soap message. I then create an ImageView and I want to insert it into the LinearLayout ‘svllid’ and show that LinearLayout in an Android Toast.

                Toast imageToast = new Toast(this);
                LinearLayout toastLayout = (LinearLayout) findViewById(R.id.svllid);
                toastLayout.addView(image,1);
                imageToast.setView(toastLayout);
                imageToast.setDuration(Toast.LENGTH_LONG);
                imageToast.show();

However, it won’t work. My application crashes with the error:

java.lang.IllegalArgumentException: View not attached to window manager

Any ideas why?

Answer 1

I believe you have to use a specific ID for the root layout. You have to name it “toast_layout” or “toast_layout_root” (not sure which one has to be used- the documentation is slightly ambigious there, try both).

And as Varun said you need to put the layout in its own layout file.

Read the Android Doc’s and follow the given example.
