参考技术A 1.自定义数字键盘2.切换到随机数字键盘
3.自定义确定和删除等键(向外抛出接口)
使用方法:
1.在项目build.gradle文件中添加jitpack，添加jitpcak就够了。allprojectsundefinedrepositoriesundefinedjcenter()mavenurl\'https://jitpack.io\'2.在module的build.gradle文件添加依赖compile\'com.github.Simon986793021:NumberKeyboard:v1.0\'3.在布局文件中添加布局android:id="@+id/keyboard_view"xmlns:android="http://schemas.android.com/apk/res/android"android:layout_android:layout_android:focusable="true"android:paddingTop="0dp"android:focusableInTouchMode="true"android:keyBackground="@drawable/bg_keyboardview"android:keyPreviewOffset="0dp"android:keyTextColor="#000"android:shadowColor="#fff"android:shadowRadius="0.0"android:layout_alignParentBottom="true"/>4.在MainActivity调用。editText=(EditText)findViewById(R.id.et_numberplate);changebutton=(Button)findViewById(R.id.bt_change_keyboard);finalOfoKeyboardkeyboard=newOfoKeyboard(MainActivity.this);//获取到keyboard对象changebutton.setOnClickListener(newView.OnClickListener()undefined@OverridepublicvoidonClick(Viewv)undefinedkeyboard.attachTo(editText,true);//eiditext绑定keyboard，true表示随机数字);editText.setOnClickListener(newView.OnClickListener()undefined@OverridepublicvoidonClick(Viewv)undefinedkeyboard.attachTo(editText,false);//eiditext绑定keyboard，false表示普通数字键盘);/*确定按钮*/keyboard.setOnOkClick(newOfoKeyboard.OnOkClick()undefined@OverridepublicvoidonOkClick()undefinedLog.i(">>>>>>","点击了确定");Toast.makeText(MainActivity.this,editText.getText().toString(),Toast.LENGTH_SHORT).show(););//隐藏键盘按钮keyboard.setOnCancelClick(newOfoKeyboard.OnCancelClcik()undefined@OverridepublicvoidonCancelClick()undefinedToast.makeText(MainActivity.this,"隐藏键盘",Toast.LENGTH_SHORT).show(););只需要这些简单的代码就能够实现一个自己定义的键盘了。实现过程1.新建一个keyboard布局在看这个代码之前需要了解keyboard的属性：不清楚属性，怎么画页面，不懂的请移步这篇博客在res新建一个xml文件，然后在xml新建一个keyboard.xml里面代码如下xmlns:android="http://schemas.android.com/apk/res/android"android:keyHeight="9%p"android:keyWidth="25%p"android:horizontalGap="0dp">android:codes="49"android:keyLabel="1"/>android:codes="50"android:keyLabel="2"/>android:codes="51"android:keyLabel="3"/>android:codes="-5"android:keyHeight="18%p"android:keyEdgeFlags="right"android:isRepeatable="true"android:keyIcon="@drawable/icon_delete_32dp"/>android:codes="52"android:keyLabel="4"/>android:codes="53"android:keyLabel="5"/>android:codes="54"android:keyLabel="6"/>android:codes="55"android:keyLabel="7"/>android:codes="56"android:keyLabel="8"/>android:codes="57"android:keyLabel="9"/>android:codes="-4"android:keyLabel="确定"android:keyEdgeFlags="right"android:keyHeight="18%p"/>android:codes="46"android:keyLabel="."/>android:codes="48"android:keyLabel="0"/>android:codes="-3"android:keyIcon="@drawable/icon_hide_keyboard"/>这个布局就是自己自定义键盘的布局实现，有了布局，显然是不够的。2.自定义KeyboardViewpackagecom.wind.keyboard;importandroid.content.Context;importandroid.graphics.Canvas;importandroid.graphics.Color;importandroid.graphics.Paint;importandroid.graphics.Rect;importandroid.graphics.Typeface;importandroid.graphics.drawable.Drawable;importandroid.inputmethodservice.Keyboard;importandroid.inputmethodservice.KeyboardView;importandroid.util.AttributeSet;importandroid.util.Log;importjava.lang.reflect.Field;importjava.util.List;/***Createdbyzhangcongon2017/8/24.*/publicclassOfoKeyboardViewextendsKeyboardViewundefinedprivateContextcontext;privateKeyboardkeyboard;publicOfoKeyboardView(Contextcontext,AttributeSetattrs)undefinedsuper(context,attrs);this.context=context;Log.i(">>>>>","构造函数被调用了");/***重新画一些按键*/@OverridepublicvoidonDraw(Canvascanvas)undefinedsuper.onDraw(canvas);keyboard=this.getKeyboard();Listkeys=null;if(keyboard!=null)undefinedkeys=keyboard.getKeys();if(keys!=null)undefinedfor(Keyboard.Keykey:keys)undefined//数字键盘的处理if(key.codes[0]==-4)undefineddrawKeyBackground(R.drawable.bg_keyboardview_yes,canvas,key);drawText(canvas,key);privatevoiddrawKeyBackground(intdrawableId,Canvascanvas,Keyboard.Keykey)undefinedDrawablenpd=context.getResources().getDrawable(drawableId);int[]drawableState=key.getCurrentDrawableState();if(key.codes[0]!=0)undefinednpd.setState(drawableState);npd.setBounds(key.x,key.y,key.x+key.width,key.y+key.height);npd.draw(canvas);privatevoiddrawText(Canvascanvas,Keyboard.Keykey)undefinedRectbounds=newRect();Paintpaint=newPaint();paint.setTextAlign(Paint.Align.CENTER);paint.setAntiAlias(true);paint.setColor(Color.WHITE);if(key.label!=null)undefinedStringlabel=key.label.toString();Fieldfield;if(label.length()>1&&key.codes.length<2)undefinedintlabelTextSize=0;tryundefinedfield=KeyboardView.class.getDeclaredField("mLabelTextSize");field.setAccessible(true);labelTextSize=(int)field.get(this);catch(NoSuchFieldExceptione)undefinede.printStackTrace();catch(IllegalAccessExceptione)undefinede.printStackTrace();paint.setTextSize(labelTextSize);paint.setTypeface(Typeface.DEFAULT_BOLD);elseundefinedintkeyTextSize=0;tryundefinedfield=KeyboardView.class.getDeclaredField("mLabelTextSize");field.setAccessible(true);keyTextSize=(int)field.get(this);catch(NoSuchFieldExceptione)undefinede.printStackTrace();catch(IllegalAccessExceptione)undefinede.printStackTrace();paint.setTextSize(keyTextSize);paint.setTypeface(Typef

做一个调节水流量的pid控制，需要让调节阀缓慢到达需求值，请问怎么做呢？
例如我想让这个阀门从0变为5立方米每小时的水量，在30秒后到达，请问该怎么去做？？？
将流量计、调节器、调节阀构成流量调节回路。如果对“30秒后到达”到达前的要求高于“稳定后的流量保持”，可选择具有“给定值SV曲线编程功能”的调节器；
如果对“30秒后到达”到达前的要求低于“稳定后的流量保持”，可选择“自动选择调节器”（超驰调节器）； 参考技术A 这个要看你的阀门大小来定，但一般是只调节PID参数中的比例、积分就可以达到了！具体达到时间还需要以现场实际调节效果为准！ 参考技术B 控制开度就行了，计算好水流量，然后控制开度就行，当然国外有一款阀门能够控制开启时间，不过很贵
