public static ToastGenerate getInstance(Context context) {
if (ourInstance == null)
ourInstance = new ToastGenerate(context);
return ourInstance;
}
//pass message and message type to this method
public void createToastMessage(String message,int type){
//inflate the custom layout
LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
LinearLayout toastLayout = (LinearLayout) layoutInflater.inflate(R.layout.layout_custome_toast,null);
TextView toastShowMessage = (TextView) toastLayout.findViewById(R.id.textCustomToastTopic);
switch (type){
case 0:
//if the message type is 0 fail toaster method will call
createFailToast(toastLayout,toastShowMessage,message);
break;
case 1:
//if the message type is 1 success toaster method will call
createSuccessToast(toastLayout,toastShowMessage,message);
break;
case 2:
createWarningToast( toastLayout, toastShowMessage, message);
//if the message type is 2 warning toaster method will call
break;
default:
createFailToast(toastLayout,toastShowMessage,message);
}
}
//Failure toast message method
private final void createFailToast(LinearLayout toastLayout,TextView toastMessage,String message){
toastLayout.setBackgroundColor(context.getResources().getColor(R.color.button_alert_normal));
toastMessage.setText(message);
toastMessage.setTextColor(context.getResources().getColor(R.color.white));
showToast(context,toastLayout);
}
//warning toast message method
private final void createWarningToast( LinearLayout toastLayout, TextView toastMessage, String message) {
toastLayout.setBackgroundColor(context.getResources().getColor(R.color.warning_toast));
toastMessage.setText(message);
toastMessage.setTextColor(context.getResources().getColor(R.color.white));
showToast(context, toastLayout);
}
//success toast message method
private final void createSuccessToast(LinearLayout toastLayout,TextView toastMessage,String message){
toastLayout.setBackgroundColor(context.getResources().getColor(R.color.success_toast));
toastMessage.setText(message);
toastMessage.setTextColor(context.getResources().getColor(R.color.white));
showToast(context,toastLayout);
}
private void showToast(View view){
Toast toast = new Toast(context);
toast.setGravity(Gravity.TOP,0,0); // show message in the top of the device
toast.setDuration(Toast.LENGTH_SHORT);
toast.setView(view);
toast.show();
