【原创】利用typeface实现不同字体的调用显示及String转换为Unicode

最近工作用到，就写个小demo

demo实现从assets中利用typeface调用不同字体，并在editText中显示出来

1.layout中创建activity_main.xml文件

布局代码如下：

 <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:background="#ffffff"
     android:orientation="vertical">

     <EditText
         android:id="@+id/edit_test1"
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         android:background="#eeeeee"
         android:focusable="true"
         android:hint="字体1" />

     <Button
         android:id="@+id/button1"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:layout_marginRight="39dp"
         android:layout_marginTop="14dp"
         android:text="字体2" />

     <EditText
         android:id="@+id/edit_test2"
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         android:layout_marginTop="50dp"
         android:background="#eeeeee"
         android:focusable="true"
         android:hint="字体1" />

     <Button
         android:id="@+id/button2"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:layout_marginRight="39dp"
         android:layout_marginTop="14dp"
         android:text="字体2" />

 </LinearLayout>

Java代码如下：

MainActivity.java

 package com.example.edittest;

 import android.app.Activity;
 import android.graphics.Typeface;
 import android.os.Bundle;
 import android.view.KeyEvent;
 import android.view.View;
 import android.view.View.OnClickListener;
 import android.widget.Button;
 import android.widget.EditText;
 import android.widget.TextView;
 import android.widget.TextView.OnEditorActionListener;
 import android.widget.Toast;

 public class MainActivity extends Activity {
     private EditText editText1;
     private EditText editText2;
     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);
         initView();
     }

     public void initView() {
         editText1 = (EditText) findViewById(R.id.edit_test1);
         editText2 = (EditText) findViewById(R.id.edit_test2);

         //调用Typeface的createFromAsset方法 这里用两个ttf文件，ziti1.ttf、ziti2.ttf，这里用的是getAssets()这个方法
         //字体1 路径为 assets目录下创建的fonts文件夹： /assets/fonts/ziti1.ttf
         Typeface typeface1 = Typeface.createFromAsset(getAssets(),
                 "fonts/ziti1.ttf");
         editText1.setTypeface(typeface1);

         // 监听回车键
         editText1.setOnEditorActionListener(new OnEditorActionListener() {
             @Override
             public boolean onEditorAction(TextView v, int actionId,
                                           KeyEvent event) {
                 Toast.makeText(MainActivity.this, String.valueOf(actionId),
                         Toast.LENGTH_SHORT).show();
                 return false;
             }
         });
         //字体2 路径为 assets目录下创建的fonts文件夹： /assets/fonts/ziti2.ttf
         Typeface typeface2 = Typeface.createFromAsset(getAssets(),
                 "fonts/ziti2.ttf");
         editText2.setTypeface(typeface2);

         // 监听回车键
         editText2.setOnEditorActionListener(new OnEditorActionListener() {
             @Override
             public boolean onEditorAction(TextView v, int actionId,
                                           KeyEvent event) {
                 Toast.makeText(MainActivity.this, String.valueOf(actionId),
                         Toast.LENGTH_SHORT).show();
                 return false;
             }
         });

         Button getValue1 = (Button) findViewById(R.id.button1);
         Button getValue2 = (Button) findViewById(R.id.button2);

         getValue1.setOnClickListener(new OnClickListener() {
             @Override
             public void onClick(View v) {
                 //Toast显示字符转换的Unicode码
                 Toast.makeText(MainActivity.this,
                         string2Unicode(editText1.getText().toString()),
                         Toast.LENGTH_SHORT).show();
             }
         });
         getValue2.setOnClickListener(new OnClickListener() {
             @Override
             public void onClick(View v) {
                 //Toast显示字符转换的Unicode码
                 Toast.makeText(MainActivity.this,
                         string2Unicode(editText2.getText().toString()),
                         Toast.LENGTH_SHORT).show();
             }
         });
     }

     // 字符串转换成Unicode
     public static String string2Unicode(String string) {
         StringBuffer unicode = new StringBuffer();
         for (int i = 0; i < string.length(); i++) {
             char c = string.charAt(i);
             unicode.append("\\u" + Integer.toHexString(c));
         }
         return unicode.toString();
     }
 }

最后在edittext中输入字符后，点击button可分别显示出对应的Unicode码。

图和demo我都不上了，很简单的一个例子，希望能帮到需要的同学。
