本文實例為大家分享了Android實現簽名塗鴉手寫板的具體代碼，供大家參考，具體內容如下
佈局文件
//開始簽名
private void StartSignature() { // 獲取屏幕尺寸 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(); } }
//創建簽名文件
private void createSignFile() { FileOutputStream fos = null; File file = null; try { path= generateImgePath(); file = new File(path); fos = new FileOutputStream(file); //如果設置成 mPaintBitmap.compress(Bitmap.CompressFormat.JPEG, 100, fos); } catch (IOException e) { e.printStackTrace(); } finally { try { if (fos != null) { fos.close(); } } catch (IOException e) { e.printStackTrace(); } } }
//重新簽名
if (mPaintView.getPath().isEmpty()){ ToastUtils.showShort(this,"您還沒有簽名呦"); }else { mPaintView.clear(); } [火星人 ] Android實現簽名塗鴉手寫板已經有498次圍觀
