Android实现签名涂鸦手写板

本文实例为大家分享了Android实现签名涂鸦手写板的具体代码，供大家参考，具体内容如下

布局文件

<?xml version="1.0" encoding="utf-8"?>

//开始签名

private void StartSignature() {    // 获取屏幕尺寸    DisplayMetrics mDisplayMetrics = new DisplayMetrics();    getWindow().getWindowManager().getDefaultDisplay().getMetrics(mDisplayMetrics);  }  @Override  public void onWindowFocusChanged(boolean hasFocus) {    super.onWindowFocusChanged(hasFocus);    if(hasFocus&&mPaintView==null){      int screenWidth = mFl_signature.getMeasuredWidth();      int screenHeight = mFl_signature.getMeasuredHeight();      mPaintView=new PaintView(getApplicationContext(),screenWidth, screenHeight);      mFl_signature.addView(mPaintView);      mPaintView.requestFocus();    }  }

//创建签名文件

private void createSignFile() {    FileOutputStream fos = null;    File file = null;    try {      path= generateImgePath();      file = new File(path);      fos = new FileOutputStream(file);      //如果设置成      mPaintBitmap.compress(Bitmap.CompressFormat.JPEG, 100, fos);    } catch (IOException e) {      e.printStackTrace();    } finally {      try {        if (fos != null) {          fos.close();        }      } catch (IOException e) {        e.printStackTrace();      }    }  }

//重新签名

if (mPaintView.getPath().isEmpty()){          ToastUtils.showShort(this,"您还没有签名呦");        }else {          mPaintView.clear();        }
