Android使用自定義字體（自定義view）

要在其他平台實現自定義字體可謂是相當的麻煩，但是在Android平台就很簡單了。

 

首先將自定義字體ttf放到“assets”下面被實例化之后再使用。

 

Typeface.createFromAsset(getContext().getAssets(),"fonts/samplefont.ttf");  

package com.yarin.android.Typefaces;  

  

import android.app.Activity;  

import android.content.Context;  

import android.graphics.Canvas;  

import android.graphics.Color;  

import android.graphics.Paint;  

import android.graphics.Typeface;  

import android.os.Bundle;  

import android.view.View;  

  

public class Typefaces extends Activity  

{  

    /** Called when the activity is first created. */  

    @Override  

    public void onCreate(Bundle savedInstanceState)  

    {  

        super.onCreate(savedInstanceState);  

          

        setContentView(new SampleView(this));  

    }  

      

    private static class SampleView extends View   

    {  

        private Paint    mPaint = new Paint(Paint.ANTI_ALIAS_FLAG);  

        private Typeface mFace;  

          

        public SampleView(Context context)   

        {  

            super(context);  

            //實例化自定義字體  

            mFace = Typeface.createFromAsset(getContext().getAssets(),"fonts/samplefont.ttf");  

            //設置字體大小  

            mPaint.setTextSize(32);  

        }  

          

        @Override protected void onDraw(Canvas canvas)   

        {  

            canvas.drawColor(Color.WHITE);  

            //繪制默認字體  

            mPaint.setTypeface(null);  

            canvas.drawText("Default:abcdefg", 10, 100, mPaint);  

            //繪制自定義字體  

            mPaint.setTypeface(mFace);  

            canvas.drawText("Custom:abcdefg", 10, 200, mPaint);  

        }  

    }  

}  

好了，就這么簡單就實現了自定義字體。

下面是兩個非常有用的方法，在這里備份一下：    

1. //消除鋸齒  
2. paint.setFlags(Paint.ANTI_ALIAS_FLAG)  
3. //取得字符串寬度  
4. paint.measureText()
