android自定义键盘按键

㈠ 关于android 自定义键盘的问题

在activity中使用的时候，首先要屏蔽掉系统软键盘，然后在输入框获取焦点的时候弹出你的键盘就OK了，键盘你可以用button来实现，或者就用一张图片算坐标重写ontouch都行；点数字的时候你就把你点的那个数字settext到你的输入框里，delete的时候你就把你输入框的文字去掉一位就OK了。如果让我做的话思路大概是这样的！

㈡ Android开发之如何自定义数字键盘详解

我曾经在项目中做过一个数字键盘，使用的是12个按钮：0~9，删除，确认
隐藏自带的手机键盘或者禁止EditText调出自带键盘，点击数字按钮时在EditText的内容中添加对应的数字，并且自己处理删除和确认的逻辑。

㈢ 安卓模拟器上怎么设置键盘按键，鼠标移动画面打手机游戏

模拟器右边工具栏有一个 按键操控

点开 就可以设置键盘按键了

模拟器里面鼠标点击 就等于手机的点击键

㈣ 如果需要做一个定制化键盘(以外型为主)的创业,如何依靠代码,在公司自有的设计

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。allprojects{undefinedrepositories{undefinedjcenter()maven{url'https://jitpack.io'}}}2.在mole的build.gradle文件添加依赖compile'com.github.Simon986793021:NumberKeyboard:v1.0Ɖ.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_width="match_parent"android:layout_height="wrap_content"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@(){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.*/{;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;try{undefinedfield=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);}else{undefinedintkeyTextSize=0;try{undefinedfield=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(Typeface.DEFAULT);}pa

㈤ android自定义键盘 如何输入中文

不同的手机品牌型号的ndroid的自定义键盘略有不同
一般在键盘的最下一排都有一个中英文转换键，点击下变中文，不过有的是全键盘拼音输入中文，有的是9键拼音中文；
在键盘上面有一排图标，是有选择手写输入、全键盘输入、9键拼音输入等各种输入法的选择键。

㈥ android 怎么改键盘按键

首先，保证手机已经ROOT，并且安装了RE文件管理器，先用RE管理器打开system\usr\keylayout下的文件s3c-keypad.kl(以文本编辑方式打开)，在目录中不同的数字对应不同的功能，看好原先对应的功能，在将数字按照喜欢的风格进行重新编写：
1.
116代表锁屏键
2.
102代表宝石键
3.
231代表拨号键
4.
217代表相机上面的键
5.
26代表挂机键
6.
115代表音量+
7.
114代表音量-
8.
158代表相机键
9.
改完立刻重启就OK了。

㈦ android自定义软键盘,如何屏蔽系统自带键盘

在需要的地方加上以下代码就行了

InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
if (imm != null) {
imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
view是你的某个控件，放在onClickListener中就可以屏蔽单击时的键盘了

㈧ 如何自定义软键盘android

软键盘实现

通过android.inputmethodservice.Keyboard只需要在XML文件中定义键盘布局就可以了，XML代码：

resxmlstock.xml
<?xmlversion="1.0"encoding="utf-8"?>
<Keyboardxmlns:android="http://schemas.android.com/apk/res/android"
android:keyWidth="20%p"
android:horizontalGap="0px"
android:verticalGap="0px"
android:keyHeight="@dimen/key_height"
>
<Row>
<Keyandroid:codes="49"android:keyLabel="1"
android:keyEdgeFlags="left"/>
<Keyandroid:codes="50"android:keyLabel="2"/>
<Keyandroid:codes="51"android:keyLabel="3"/>
<Keyandroid:codes="52"android:keyLabel="4"/>
<Keyandroid:codes="53"android:keyLabel="5"
android:keyEdgeFlags="right"/>
</Row>
<Row>
<Keyandroid:codes="54"android:keyLabel="6"

<Keyandroid:codes="55"android:keyLabel="7"/>
<Keyandroid:codes="56"android:keyLabel="8"/>
<Keyandroid:codes="57"android:keyLabel="9"/>
<Keyandroid:codes="48"android:keyLabel="0"

</Row>
<Row>

<Keyandroid:codes="46"android:keyLabel="."/>
<Keyandroid:codes="-5"

<Keyandroid:keyOutputText="600"android:keyLabel="600"

㈨ android的手机，键盘定义fn键，用作数字和字母切换，请问这个键值应该定义成多少

如果是自定义键盘里面的话，xml文件里面的简直可以是-3，如下内容：
<Key android:codes="-3" android:keyWidth="20%p"
android:keyIcon="@drawable/sym_keyboard_done"
android:keyEdgeFlags="left" />
