如何設置SquareTextView TypeFace

Question

我試圖使用SquareTextView來設置地圖標記的集羣圖標的自定義字體，什麼是android-maps-utils-amap庫擴展TextView的類。在DefaultClusterRenderer我使用此代碼來設置自定義字體，但沒有效果。所以，請幫助我明白我需要做什麼來改變SquareTextView

private SquareTextView makeSquareTextView(Context context) { 
    SquareTextView squareTextView = new SquareTextView(context);    
    Typeface typeface = Typeface.createFromAsset(context.getAssets(), "whatever.ttf"); 
    squareTextView.setTypeface(typeface); 
} 

的字體，這是SquareTextView源代碼：

package com.amap.api.maps2d.ui; 

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

public class SquareTextView extends TextView { 
    private int mOffsetTop = 0; 
    private int mOffsetLeft = 0; 

    public SquareTextView(Context context) { 
     super(context); 
    } 

    public SquareTextView(Context context, AttributeSet attrs) { 
     super(context, attrs); 
    } 

    public SquareTextView(Context context, AttributeSet attrs, int defStyle) { 
     super(context, attrs, defStyle); 
    } 

    @Override 
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { 
     super.onMeasure(widthMeasureSpec, heightMeasureSpec); 
     int width = getMeasuredWidth(); 
     int height = getMeasuredHeight(); 
     int dimension = Math.max(width, height); 
     if (width > height) { 
      mOffsetTop = width - height; 
      mOffsetLeft = 0; 
     } else { 
      mOffsetTop = 0; 
      mOffsetLeft = height - width; 
     } 
     setMeasuredDimension(dimension, dimension); 
    } 

    @Override 
    public void draw(Canvas canvas) { 
     canvas.translate(mOffsetLeft/2, mOffsetTop/2); 
     super.draw(canvas); 
    } 
}

我有自己實施的TextView我用它設置字體像下面，和它的工作對我來說：

public class MyNewTextView extends TextView { 
private int mOffsetTop = 0; 
private int mOffsetLeft = 0; 

public MyNewTextView(Context context) { 
    super(context); 
} 

public MyNewTextView(Context context, AttributeSet attrs, int defStyle) { 
    super(context, attrs, defStyle); 
} 

public MyNewTextView(Context context, AttributeSet attrs) { 
    super(context, attrs); 
} 

@Override 
public void setTypeface(Typeface tf, int style) { 
    super.setTypeface(Typeface.createFromAsset(getContext().getAssets(), "fonts/whatever.ttf"), style); 
} 

@Override 
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { 
    super.onMeasure(widthMeasureSpec, heightMeasureSpec); 
    int width = getMeasuredWidth(); 
    int height = getMeasuredHeight(); 
    int dimension = Math.max(width, height); 
    if (width > height) { 
     mOffsetTop = width - height; 
     mOffsetLeft = 0; 
    } else { 
     mOffsetTop = 0; 
     mOffsetLeft = height - width; 
    } 
    setMeasuredDimension(dimension, dimension); 
} 

@Override 
public void draw(Canvas canvas) { 
    canvas.translate(mOffsetLeft/2, mOffsetTop/2); 
    super.draw(canvas); 
} 
} 

所以要儘量覆蓋setTypeface（）用於SquareTextView

Answer 2

讓自己實現SquareTextView試試這個：

public class MySquareTextView extends SquareTextView { 

    public MySquareTextView (Context context) { 
     super(context); 
     setTypeface(); 
    } 

    public MySquareTextView (Context context, AttributeSet attrs) { 
     super(context, attrs); 
     setTypeface(); 
    } 

    public MySquareTextView (Context context, AttributeSet attrs, int defStyle) { 
     super(context, attrs, defStyle); 
     setTypeface(); 
    } 


    public void setTypeface(){ 
     setTypeface(Typeface.createFromAsset(getAssets(), "Roboto-Italic.ttf")); 
    } 
}
