实现步骤
1、添加画板控件module
画板控件module下载：https://download.csdn.net/download/meixi_android/10774781
2、xml文件
<?xml version="1.0" encoding="utf-8"?> <LinearLayoutandroid:id="@+id/content_main"xmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"android:background="@color/white"app:layout_behavior="@string/appbar_scrolling_view_behavior"><LinearLayoutandroid:layout_width="match_parent"android:layout_height="8dp"android:layout_marginTop="8dp"android:background="@color/blistlic"></LinearLayout><Buttonandroid:id="@+id/btn_reset"xmlns:app="http://schemas.android.com/apk/res-auto"android:layout_width="match_parent"android:layout_height="40dp"android:layout_margin="10dp"android:text="重置"android:textSize="16dp"android:textColor="#fff"android:background="@drawable/selebuttonbg"/><Buttonandroid:id="@+id/btn_bitmap"xmlns:app="http://schemas.android.com/apk/res-auto"android:layout_width="match_parent"android:layout_height="40dp"android:layout_margin="10dp"android:text="确认"android:textSize="16dp"android:background="@drawable/selebuttonbg"android:textColor="#fff" /><com.unco.library.PainterViewandroid:id="@+id/painter"android:layout_width="match_parent"android:layout_height="match_parent"android:background="@color/defaulcolor"/> </LinearLayout>
