我一直在試圖創建像這張照片一樣的3d文本如何在android中創建3D文本

爲此,我編寫了下面的代碼。它幾乎是從前面看到的3d,但如果在x軸上旋轉,它有一個點在90度處消失。 對於三維文字,商店中也很少有應用程序。 我首先將文本轉換爲位圖,然後應用疊加以提供3D效果。

img= (ImageView) findViewById(R.id.imageView); 
    skBar= (SeekBar) findViewById(R.id.seekBar); 
    Bitmap bm = BitmapFactory.decodeResource(getResources(), R.drawable.img); 
    bm = textAsBitmap("TEXT CHECK", 140.0f, Color.BLUE); 
    img.setImageBitmap(overlay(bm,bm)); 
    skBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() { 
     @Override 
     public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) { 
      img.setRotationY(Float.parseFloat(String.valueOf(progress))); 
     } 

     @Override 
     public void onStartTrackingTouch(SeekBar seekBar) { 

     } 

     @Override 
     public void onStopTrackingTouch(SeekBar seekBar) { 

     } 
    }); 


public static Bitmap overlay(Bitmap bmp1, Bitmap bmp2) { 
    Bitmap bmOverlay = Bitmap.createBitmap(bmp1.getWidth(), bmp1.getHeight(), bmp1.getConfig()); 
    Canvas canvas = new Canvas(bmOverlay); 
    canvas.drawBitmap(bmp1, new Matrix(), null); 
    for (float i = 20; i > 0; i-=0.5f) { 
     canvas.drawBitmap(bmp2, i, i, null); 
    } 
    for (float i = 1; i <= 20; i+=0.5f) { 
     canvas.drawBitmap(bmp2, i, i, null); 
    } 
    return bmOverlay; 
} 
public Bitmap textAsBitmap(String text, float textSize, int textColor) { 
    Paint paint = new Paint(); 
    paint.setTextSize(textSize); 
    paint.setColor(textColor); 
    paint.setTextAlign(Paint.Align.LEFT); 
    paint.setTextScaleX(1.5f); 
    // paint.setTexth(5.0f); 
    float baseline = -paint.ascent(); // ascent() is negative 
    int width = (int) (paint.measureText(text) + 0.5f); // round 
    int height = (int) (baseline + paint.descent() + 0.5f); 
    Bitmap image = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888); 
    Canvas canvas = new Canvas(image); 
    canvas.drawText(text, 0, baseline, paint); 
    return image; 
}
