  • 【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:

     1 <LinearLayout xmlns: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     <EditText
     9         android:id="@+id/edit_test1"
    10         android:layout_width="match_parent"
    11         android:layout_height="wrap_content"
    12         android:background="#eeeeee"
    13         android:focusable="true"
    14         android:hint="字体1" />
    15 
    16     <Button
    17         android:id="@+id/button1"
    18         android:layout_width="wrap_content"
    19         android:layout_height="wrap_content"
    20         android:layout_marginRight="39dp"
    21         android:layout_marginTop="14dp"
    22         android:text="字体2" />
    23 
    24     <EditText
    25         android:id="@+id/edit_test2"
    26         android:layout_width="match_parent"
    27         android:layout_height="wrap_content"
    28         android:layout_marginTop="50dp"
    29         android:background="#eeeeee"
    30         android:focusable="true"
    31         android:hint="字体1" />
    32 
    33     <Button
    34         android:id="@+id/button2"
    35         android:layout_width="wrap_content"
    36         android:layout_height="wrap_content"
    37         android:layout_marginRight="39dp"
    38         android:layout_marginTop="14dp"
    39         android:text="字体2" />
    40 
    41 </LinearLayout>

    Java代码如下:

    MainActivity.java

     1 package com.example.edittest;
     2 
     3 import android.app.Activity;
     4 import android.graphics.Typeface;
     5 import android.os.Bundle;
     6 import android.view.KeyEvent;
     7 import android.view.View;
     8 import android.view.View.OnClickListener;
     9 import android.widget.Button;
    10 import android.widget.EditText;
    11 import android.widget.TextView;
    12 import android.widget.TextView.OnEditorActionListener;
    13 import android.widget.Toast;
    14 
    15 public class MainActivity extends Activity {
    16     private EditText editText1;
    17     private EditText editText2;
    18     @Override
    19     protected void onCreate(Bundle savedInstanceState) {
    20         super.onCreate(savedInstanceState);
    21         setContentView(R.layout.activity_main);
    22         initView();
    23     }
    24 
    25     public void initView() {
    26         editText1 = (EditText) findViewById(R.id.edit_test1);
    27         editText2 = (EditText) findViewById(R.id.edit_test2);
    28 
    29         //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
    30         //字体1 路径为 assets目录下创建的fonts文件夹: /assets/fonts/ziti1.ttf
    31         Typeface typeface1 = Typeface.createFromAsset(getAssets(),
    32                 "fonts/ziti1.ttf");
    33         editText1.setTypeface(typeface1);
    34 
    35         // 监听回车键
    36         editText1.setOnEditorActionListener(new OnEditorActionListener() {
    37             @Override
    38             public boolean onEditorAction(TextView v, int actionId,
    39                                           KeyEvent event) {
    40                 Toast.makeText(MainActivity.this, String.valueOf(actionId),
    41                         Toast.LENGTH_SHORT).show();
    42                 return false;
    43             }
    44         });
    45         //字体2 路径为 assets目录下创建的fonts文件夹: /assets/fonts/ziti2.ttf
    46         Typeface typeface2 = Typeface.createFromAsset(getAssets(),
    47                 "fonts/ziti2.ttf");
    48         editText2.setTypeface(typeface2);
    49 
    50         // 监听回车键
    51         editText2.setOnEditorActionListener(new OnEditorActionListener() {
    52             @Override
    53             public boolean onEditorAction(TextView v, int actionId,
    54                                           KeyEvent event) {
    55                 Toast.makeText(MainActivity.this, String.valueOf(actionId),
    56                         Toast.LENGTH_SHORT).show();
    57                 return false;
    58             }
    59         });
    60 
    61         Button getValue1 = (Button) findViewById(R.id.button1);
    62         Button getValue2 = (Button) findViewById(R.id.button2);
    63 
    64         getValue1.setOnClickListener(new OnClickListener() {
    65             @Override
    66             public void onClick(View v) {
    67                 //Toast显示字符转换的Unicode码
    68                 Toast.makeText(MainActivity.this,
    69                         string2Unicode(editText1.getText().toString()),
    70                         Toast.LENGTH_SHORT).show();
    71             }
    72         });
    73         getValue2.setOnClickListener(new OnClickListener() {
    74             @Override
    75             public void onClick(View v) {
    76                 //Toast显示字符转换的Unicode码
    77                 Toast.makeText(MainActivity.this,
    78                         string2Unicode(editText2.getText().toString()),
    79                         Toast.LENGTH_SHORT).show();
    80             }
    81         });
    82     }
    83 
    84     // 字符串转换成Unicode
    85     public static String string2Unicode(String string) {
    86         StringBuffer unicode = new StringBuffer();
    87         for (int i = 0; i < string.length(); i++) {
    88             char c = string.charAt(i);
    89             unicode.append("\u" + Integer.toHexString(c));
    90         }
    91         return unicode.toString();
    92     }
    93 }

    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。
