"Original" uses typeface to implement different font invocation display and string conversion to Unicode

I've been working on it lately, just write a little demo.

The demo implementation uses typeface to invoke different fonts from assets and displays them in EditText

Create a activity_main.xml file in 1.layout

The layout code is as follows:

1 <LinearLayoutxmlns:android= "Http://schemas.android.com/apk/res/android"2 Xmlns:tools= "Http://schemas.android.com/tools"3 Android:layout_width= "Match_parent"4 Android:layout_height= "Match_parent"5 Android:background= "#ffffff"6 android:orientation= "vertical">7 8     <EditText9         Android:id= "@+id/edit_test1"Ten Android:layout_width= "Match_parent" One Android:layout_height= "Wrap_content" A Android:background= "#eeeeee" - android:focusable= "true" - Android:hint= "Font 1" /> the  -     <Button -         Android:id= "@+id/button1" - Android:layout_width= "Wrap_content" + Android:layout_height= "Wrap_content" - Android:layout_marginright= "39DP" + Android:layout_margintop= "14DP" A Android:text= "Font 2" /> at  -     <EditText -         Android:id= "@+id/edit_test2" - Android:layout_width= "Match_parent" - Android:layout_height= "Wrap_content" - Android:layout_margintop= "50DP" in Android:background= "#eeeeee" - android:focusable= "true" to Android:hint= "Font 1" /> +  -     <Button the         Android:id= "@+id/button2" * Android:layout_width= "Wrap_content" $ Android:layout_height= "Wrap_content"Panax Notoginseng Android:layout_marginright= "39DP" - Android:layout_margintop= "14DP" the Android:text= "Font 2" /> +  A </LinearLayout>

The Java code is as follows:

Mainactivity.java

1  Packagecom.example.edittest;2 3 Importandroid.app.Activity;4 ImportAndroid.graphics.Typeface;5 ImportAndroid.os.Bundle;6 Importandroid.view.KeyEvent;7 ImportAndroid.view.View;8 ImportAndroid.view.View.OnClickListener;9 ImportAndroid.widget.Button;Ten ImportAndroid.widget.EditText; One ImportAndroid.widget.TextView; A ImportAndroid.widget.TextView.OnEditorActionListener; - ImportAndroid.widget.Toast; -  the  Public classMainactivityextendsActivity { -     PrivateEditText EditText1; -     PrivateEditText editText2; - @Override +     protected voidonCreate (Bundle savedinstancestate) { -         Super.

This, String.valueof (ActionId), A toast.length_short). Show (); the                 return false; +             } -         }); $         //the Font 2 path is the Fonts folder created under the assets directory:/assets/fonts/ziti2.ttf $Typeface Typeface2 =Typeface.createfromasset (Getassets (), -"Fonts/ziti2.ttf"); - Edittext2.settypeface (TYPEFACE2); the  -         //Monitor EnterWuyiEdittext2.setoneditoractionlistener (NewOneditoractionlistener () { the @Override -              Public BooleanOneditoraction (TextView V,intActionId, Wu KeyEvent Event) { -Toast.maketext (mainactivity.

Show (); $                 return false; -             } -         }); -  AButton getValue1 =(Button) Findviewbyid (r.id.button1); +Button getValue2 =(Button) Findviewbyid (r.id.button2); the  -Getvalue1.setonclicklistener (NewOnclicklistener () { $ @Override the              Public voidOnClick (View v) { the                 //Toast display Unicode code for character conversion theToast.maketext (mainactivity. This, the String2unicode (Edittext1.gettext (). toString ()), - toast.length_short). Show (); in             } the         }); theGetvalue2.setonclicklistener (NewOnclicklistener () { About @Override the              Public voidOnClick (View v) { the                 //Toast display Unicode code for character conversion theToast.maketext (mainactivity. This, + String2unicode (Edittext2.gettext (). toString ()), - toast.length_short). Show (); the             }Bayi         }); the     } the  -     //string converted to Unicode -      Public Staticstring String2unicode (String string) { theStringBuffer Unicode =NewStringBuffer (); the          for(inti = 0; I < string.length (); i++) { the             Charc =String.charat (i); theUnicode.append ("\\u" +integer.tohexstring (c)); -         } the         returnunicode.tostring (); the     } the}

Finally, after entering the characters in the EditText, click the button to display the corresponding Unicode code separately.

Diagram and demo I do not go, a very simple example, I hope to help the students in need.
