【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。
