Android get toast position

Question

I'm able to fetch every (default) toast message, but I want to add the app icon to it. How can I get the position from the toast view/widget?

My toast catcher is an AccessibilityService and I was hoping that the AccessibilityEvent has something useful in it, but I didn't find a property with the needed data.

Edit: CyanogenMod added it and I want to implement it into stock android with my app.

Because the toast ist from a different app, I'm not allowed to edit the toast. My idea was to overlay the app icon and because of that I need the position. Is there an other way? — mars3142, Sep 15 '15 at 10:26
sorry but i'm not sure i got it, so you wanna hide the toast by overlaying it with another view, right? — Pier Giorgio Misley, Sep 15 '15 at 10:29

You can change the position of Toast Message

setGravity(int gravity, int xOffset, int yOffset)

As you know your Toast message position you can simply set your icon position accordingly doc

the toast is not in his app, so he can't access it with setGravity :S – Pier Giorgio Misley Sep 15 '15 at 10:45

Can you please try Custom toast ?

Screen shot attached for the same.

custom_toast_view.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/toastParent"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="#F08080"
    android:gravity="center_vertical"
    android:orientation="horizontal"
    android:padding="10dp" >

    <ImageView
        android:id="@+id/image"
        android:layout_width="30dp"
        android:layout_height="30dp"
        android:layout_marginRight="10dp"
        android:contentDescription="@string/app_name" />

    <TextView
        android:id="@+id/text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textColor="#FFF" />

</LinearLayout>

In Java class:

private void displayToast(){
   LayoutInflater inflater = getLayoutInflater();
   View layout = inflater.inflate(R.layout.custom_toast_view, (ViewGroup) findViewById(R.id.toastParent));
   ImageView image = (ImageView) layout.findViewById(R.id.image);
   image.setImageResource(R.drawable.ic_launcher);
   TextView text = (TextView) layout.findViewById(R.id.text);
   text.setText("Hello! This is a custom toast!");
   Toast toast = new Toast(getApplicationContext());
   toast.setDuration(Toast.LENGTH_LONG);
   toast.setView(layout);
   toast.show();
}

Hope this will help you.

My app (https://play.google.com/store/apps/details?id=org.mars3142.android.toaster) will catch every toast. So, I can't use custom layouts. I don't want to disable the original toast and show a custom one — mars3142, Sep 15 '15 at 11:31

With the following code you can get default Toast Y offset from bottom of the screen:

int i = Resources.getSystem().getIdentifier("toast_y_offset", "dimen", "android");
int bottomOffset = getResources().getDimensionPixelSize(i);

Then just place your image at the bottom of the screen with bottom padding == bottomOffset.

Answer on "where do I get the left position?":

Toast uses android:layout_gravity="center_horizontal" to align text and default text size. So you can calculate how many space this text would take (if you know what the exact text would be) : Calculating width of a string on Android . Then left offset can be calculated as (screenWidth - textWidth) / 2.

And where do I get the left position? – mars3142 Sep 15 '15 at 11:35
This could be the only possible way (manual calculation), if I can't read the data from elsewhere. – mars3142 Sep 15 '15 at 12:53
