Android中自定義textview可以進行自體設置

廢話不說，下面是代碼：

package com.windy.androidfont;

import android.content.Context;
import android.graphics.Typeface;
import android.util.AttributeSet;
import android.widget.TextView;

public class FontTextView extends TextView {
    private Context mContext;
    private String TypefaceName = "";

    public String getTypefaceName() {
        return TypefaceName;
    }

    public void setTypefaceName(String typefaceName) {
        TypefaceName = typefaceName;
        Typeface typeface = Typeface.createFromAsset(mContext.getAssets(), "font/" + TypefaceName + ".ttf");
        this.setTypeface(typeface);
        System.gc();
    }

    public FontTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        this.mContext = context;
        int resouceId = attrs.getAttributeResourceValue(null, "typefaceName", 0);
        if (resouceId != 0) {
            TypefaceName = context.getResources().getString(resouceId);
        } else {
            TypefaceName = attrs.getAttributeValue(null, "typefaceName");
        }
        if (TypefaceName != null && !"".equals(TypefaceName)) {
            Typeface typeface = Typeface.createFromAsset(context.getAssets(), "font/" + TypefaceName + ".ttf");
            this.setTypeface(typeface);
        }
    }

    public FontTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        this.mContext = context;
        // 先判斷是否配置的資源文件
        int resouceId = attrs.getAttributeResourceValue(null, "typefaceName", 0);
        if (resouceId != 0) {
            TypefaceName = context.getResources().getString(resouceId);
        } else {
            TypefaceName = attrs.getAttributeValue(null, "typefaceName");
        }
        if (TypefaceName != null && !"".equals(TypefaceName)) {
            Typeface typeface = Typeface.createFromAsset(context.getAssets(), "font/" + TypefaceName + ".ttf");
            this.setTypeface(typeface);
        }
    }

    public FontTextView(Context context) {
        super(context);
        this.mContext = context;
        // TypefaceName = attrs.getAttributeValue(null, "TypefaceName");
        if (TypefaceName != null && !"".equals(TypefaceName)) {
            Typeface typeface = Typeface.createFromAsset(context.getAssets(), "font/" + TypefaceName + ".ttf");
            this.setTypeface(typeface);
        }
    }
}

下面是布局：

<com.example.androidfont.FontTextView
        android:id="@+id/fontTextView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="69dp" typefaceName="pop"
        android:text="FontTextView"
        android:textSize="30sp" />
大字體是要設置的屬性，pop是字體庫的名字

注意：自體庫文件我這里放到了assets中的font文件夾中給個截圖吧：

strings.xml文件中的截圖：可以把字體的配置放到字符串資源中，這樣就能統一進行更改了，如果你的需要中要動態的進行配置的話，可以對FontTextView進行改寫，我的想法是在將自體配置放進prefrence中進行配置，這樣就可以直接在FontTextView中進行改寫了，本來想把這個類寫的完成呢，由於時間關系就沒寫，有需求的可以自己去實現。就說這么多吧。
