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"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <FrameLayout android:id="@+id/fl_signature" android:layout_width="fill_parent" android:layout_height="200dp" android:layout_marginLeft="20dp" android:layout_marginRight="20dp" android:layout_marginTop="10dp" android:background="@drawable/singature_bg" android:gravity="top"> </FrameLayout> <ImageView android:id="@+id/iv_signature" android:layout_width="fill_parent" android:layout_height="200dp" android:layout_marginLeft="20dp" android:layout_marginRight="20dp" android:layout_marginTop="10dp" android:background="@drawable/signature_shape" android:gravity="top" android:visibility="gone"/> <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="20dp" android:layout_marginBottom="20dp"> <TextView android:id="@+id/tv_revert_signature" android:layout_width="100dp" android:layout_height="35dp" android:layout_alignParentRight="true" android:layout_marginRight="140dp" android:background="@drawable/btn_order_details_pay_bg" android:gravity="center" android:paddingLeft="30dp" android:paddingRight="30dp" android:text="重签" android:textColor="@color/code_number_bg" android:textSize="@dimen/text_title_word" /> <TextView android:id="@+id/tv_signature_save" android:layout_width="100dp" android:layout_height="35dp" android:layout_alignParentRight="true" android:layout_marginRight="20dp" android:background="@drawable/bt_bg" android:gravity="center" android:paddingLeft="30dp" android:paddingRight="30dp" android:text="保存" android:textColor="@color/white" android:textSize="@dimen/text_title_word" /> </RelativeLayout></LinearLayout>

//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(); }
