Android Using External Fonts

http://javatechig.com/android/using-external-fonts-in-android-view

import android.content.Context;
import android.graphics.Typeface;
import android.util.AttributeSet;
import android.widget.TextView;

public class CustomTextView extends TextView {
 public CustomTextView(Context context) {
  super(context);
  setFont();
 }
 public CustomTextView(Context context, AttributeSet attrs) {
  super(context, attrs);
  setFont();
 }
 public CustomTextView(Context context, AttributeSet attrs, int defStyle) {
  super(context, attrs, defStyle);
  setFont();
 }

 private void setFont() {
  Typeface font = Typeface.createFromAsset(getContext().getAssets(),
    "fonts/Maximum.ttf");
  setTypeface(font, Typeface.NORMAL);
 }
}

Now change the following in your android layout xml file
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity"
android:background="#0F0F0F">

<com.javatechig.droid.ui.CustomTextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/font_sample_text"
android:textSize="18dp"
android:textColor="#AAD4DE" />

<com.javatechig.droid.ui.CustomTextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/font_sample_text"
android:textColor="#FFDE46"
android:textSize="24dp"/>

<com.javatechig.droid.ui.CustomTextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/font_sample_text"
android:textSize="30dp"
android:textColor="#7FBA00"/>

</LinearLayout>

Android Toast

http://javatechig.com/android/android-toast-example

Toast toast = Toast.makeText(getApplicationContext(), "Your toast message.",
                      Toast.LENGTH_SHORT);
toast.setGravity(Gravity.TOP|Gravity.LEFT, 0, 0);
toast.show();

Custom Toast:

//get the LayoutInflater and inflate the custom_toast layout
LayoutInflater inflater = getLayoutInflater();
View layout = inflater.inflate(R.layout.custom_toast, (ViewGroup)
findViewById(R.id.toast_layout_root));

//get the TextView from the custom_toast layout
TextView text = (TextView) layout.findViewById(R.id.toastText);
text.setText("This is my custom toast");

//create the toast object, set display duration,
//set the view as layout that's inflated above and then call show()
Toast t = new Toast(getApplicationContext());
t.setDuration(Toast.LENGTH_LONG);
t.setView(layout);
t.show();

For Framework

====Dau phay:

String dichvu="";

boolean fr=subDtResp.isUseFunring();

if(fr)
dichvu+="FR";
