Android Overlay Text

Question

Trying to attract car sensors in android using Paint and ondraw () using open source code. The sensors worked well, but there were problems with Android 4 and above. After that, the Paint object changed by setting setLinearText (true), because of which everything works. But now the text in the sensors began to overlap, and everything looks blurry, as shown in the image.

Below is the source code used to draw gauges, texts and lines on the screen. Need help drawing text that doesn't overlap.

    private void initDrawingTools() {
    rimRect = new RectF(0.1f, 0.1f, 0.9f, 0.9f);

    // the linear gradient is a bit skewed for realism
    rimPaint = new Paint();
    rimPaint.setFlags(Paint.ANTI_ALIAS_FLAG);
    rimPaint.setShader(new LinearGradient(0.40f, 0.0f, 0.60f, 1.0f, 
                                       Color.rgb(0xf0, 0xf5, 0xf0),
                                       Color.rgb(0x30, 0x31, 0x30),
                                       Shader.TileMode.CLAMP));     

    rimCirclePaint = new Paint();
    rimCirclePaint.setAntiAlias(true);
    rimCirclePaint.setStyle(Paint.Style.STROKE);
    rimCirclePaint.setColor(Color.argb(0x4f, 0x33, 0x36, 0x33));
    rimCirclePaint.setStrokeWidth(0.005f);

    float rimSize = 0.02f;

    faceTexture = BitmapFactory.decodeResource(getContext().getResources(), 
               R.drawable.plastic);
    BitmapShader paperShader = new BitmapShader(faceTexture, 
                                                Shader.TileMode.MIRROR,
