Android Toast

With code

// create instance
Toast toast = Toast.makeText(context, text, duration);

// set message color
TextView textView= (TextView) toast.getView().findViewById(android.R.id.message);  
textView.setTextColor(Color.YELLOW);

// set background color
toast.getView().setBackgroundColor(getResources().getColor(R.color.indigo));  

With custom view

I. Declare your custom view inside of any layout.xml file.

<?xml version="1.0" encoding="utf-8"?>  
<TextView  
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/txtMessage"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:drawableStart="@drawable/ic_report_problem"
        android:drawablePadding="8dp"
        android:paddingTop="8dp"
        android:paddingBottom="8dp"
        android:paddingLeft="16dp"
        android:paddingRight="16dp"
        android:gravity="center"
        android:textColor="@android:color/white"
        android:textSize="16dp"
        android:text="No connection."
        android:background="@color/indigo"/>

II. Set your custom view to Toast via setView() method.

// create instance
Toast toast = new Toast(getApplicationContext());

// inflate custom view
View view = getLayoutInflater().inflate(R.layout.toast_view, null);

// set custom view
toast.setView(view);

// set duration
toast.setDuration(Toast.LENGTH_LONG);

// set position
int margin = getResources().getDimensionPixelSize(R.dimen.toast_vertical_margin);  
toast.setGravity(Gravity.BOTTOM | Gravity.CENTER_VERTICAL, 0, margin);

// show toast
toast.show();
