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

//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();

 }
