Android Socket instance (6) KEY operation, that is, hot KEY operation

Android interface design optimization, service Settings and dynamic return

This more content:

KEY operation, that is, hotkey operation, this more to achieve THE PC slide control and common shortcut keys as an example.

Virtual machines are not convenient to display functions. You are advised to use a real machine for debugging. The following figure shows virtual machine debugging

Server update

Added key operations, which parse key commands from Android and perform functions

The new KEY. Java

Implement PC side press the specified key method class

package lrz.data; import lrz.base.BaseOperator; import lrz.tool.VisualKeyMap; import java.awt.*; import java.util.ArrayList; public class KEY extends BaseOperator { private Robot robot; @Override public ArrayList<String> exe(String cmdBody) throws Exception { ArrayList<String> ackMsg = new ArrayList<String>(); robot=new Robot(); int splitIdx = cmdBody.indexOf(","); if (splitIdx < 1) { int splitIdx2 = cmdBody.indexOf("+"); if(splitIdx2<1){ singleKeyPress(cmdBody); }else{ simpleComboKeyPress(cmdBody); }}else{String keyPressStr=cmdBody. subString (0, splitIdx); String keyReleaseStr=cmdBody.substring(splitIdx+1); comboKeyPress(keyPressStr,keyReleaseStr); } ackmsg. add(" successfully run hotkey :"+cmdBody); return ackMsg; } private void simpleComboKeyPress(String keyPressStr){ String[] keyPressArray = keyPressStr.split("\\+"); For (int I =0; for(int I =0; for(int I =0; i<keyPressArray.length; i++){ int keycode = VisualKeyMap.getVisualKey(keyPressArray[i]); robot.keyPress(keycode); } for(int i=keyPressArray.length-1; i>=0; I -) {/ / release order button int keycode. = VisualKeyMap getVisualKey (keyPressArray [I]); robot.keyRelease(keycode); } } private void comboKeyPress(String keyPressStr, String keyReleaseStr) { // TODO Auto-generated method stub String[] keyPressArray = keyPressStr.split("\\+"); String[] keyReleaseArray = keyReleaseStr.split("\\+"); for(int i=0; i<keyPressArray.length; i++){ int keycode = VisualKeyMap.getVisualKey(keyPressArray[i]); robot.keyPress(keycode); } for(int i=0; i<keyReleaseArray.length; i++){ int keycode = VisualKeyMap.getVisualKey(keyReleaseArray[i]); robot.keyRelease(keycode); } } private void singleKeyPress(String cmdBody) { // TODO Auto-generated method stub int keycode = VisualKeyMap.getVisualKey(cmdBody); robot.keyPress(keycode); robot.keyRelease(keycode); }}Copy the code

New VisualKeyMap. Java

Store the shortcut keys we want to use, set here to call directly when using

package lrz.tool; import java.awt.event.KeyEvent; import java.util.HashMap; public class VisualKeyMap { private static HashMap<String, Integer> hashMap = new HashMap<String, Integer>(); private static final VisualKeyMap VISUAL_KEY_MAP = new VisualKeyMap(); private VisualKeyMap() { hashMap.put("VK_0", KeyEvent.VK_0); Hashmap. put("VK_TAB", keyevent.vk_tab); hashMap.put("VK_ALT", KeyEvent.VK_ALT); hashMap.put("VK_ESCAPE", KeyEvent.VK_ESCAPE); hashMap.put("VK_LEFT", KeyEvent.VK_LEFT); hashMap.put("VK_RIGHT", KeyEvent.VK_RIGHT); hashMap.put("VK_F5", KeyEvent.VK_F5); hashMap.put("VK_F4", KeyEvent.VK_F4); hashMap.put("LEFT", KeyEvent.BUTTON1_MASK); hashMap.put("RIGHT", KeyEvent.BUTTON3_MASK); hashMap.put("WIN", KeyEvent.VK_WINDOWS); hashMap.put("VK_D", KeyEvent.VK_D); hashMap.put("VK_CTRL", KeyEvent.VK_CONTROL); hashMap.put("VK_V", KeyEvent.VK_V); / / is omitted the need to increase the mapping operation} public static int getVisualKey (String key) {/ / call just VisualKeyMap getVisualKey (String key) to return hashMap.get(key.toUpperCase()); // Uppercase key}}Copy the code

Operator.java

Added operation invocation after key command resolution

if (cmdHead.equals("key")) { msgBackList = new KEY().exe(cmdBody); Msgbacklist.add (0,"key"); // add "ok" return msgBackList; }Copy the code

Android update

Add hotkey operation, slide control panel, generate key operation command when triggering event, and submit server through SocketClient

Added dialog_view_opt_do.xml layout

The XML version = "1.0" encoding = "utf-8"? > < menu XMLNS: android = "http://schemas.android.com/apk/res/android" > < item android: id = "@ + id/to_do" android: title = "hotkey operation" / > <item Android :id="@+id/to_show" Android :title=" slide control "/> <item Android :id="@+ ID /to_set" Android :title=" setup "/> </menu>Copy the code

Update the SocketClient. Java

Public static int SERVER_MSG_KEY=4; // Returns the KEY operation

        else if(status.equalsIgnoreCase("KEY")){
            msgType=SERVER_MSG_KEY;
        }
Copy the code

Update MainActivity. Java

Added hotkey and slide control options in function selection

                    case R.id.to_do:

                        break;
Copy the code

Add the corresponding showDialog_opt_do and showDialog_opt_show methods to realize the corresponding panel pop-up

public void showDialog_opt_do(final Context context){ AlertDialog.Builder bl = new AlertDialog.Builder(context); Bl.settitle (" Control panel "); View v = LayoutInflater.from(context).inflate(R.layout.dialog_view_opt_do, null, false); final Button bt1=v.findViewById(R.id.vk_alt_tab); final Button bt2=v.findViewById(R.id.vk_f5); final Button bt3=v.findViewById(R.id.vk_win_d); final Button bt4=v.findViewById(R.id.vk_ctrl_f4); bt1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { socketClient=new SocketClient(ip,Integer.parseInt(port),handler); socketClient.work("key:vk_alt+vk_tab,vk_tab+vk_alt"); }}); bt2.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { socketClient=new SocketClient(ip,Integer.parseInt(port),handler); socketClient.work("key:vk_f5"); }}); bt3.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { socketClient=new SocketClient(ip,Integer.parseInt(port),handler); socketClient.work("key:win+vk_d,vk_d+win"); }}); bt4.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { socketClient=new SocketClient(ip,Integer.parseInt(port),handler); socketClient.work("key:vk_ctrl+vk_f4,vk_f4+vk_ctrl"); }}); bl.setView(v); bl.setPositiveButton("OK", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, Int which) {String s = "shortcut mode closed "; Toast.makeText(context,s,Toast.LENGTH_SHORT).show(); }}); bl.create().show(); } public void show_Dialog_opt_show(final Context context){ AlertDialog.Builder bl = new AlertDialog.Builder(context); Bl.settitle (" slide control "); View v = LayoutInflater.from(context).inflate(R.layout.dialog_view_opt_show, null, false); final Button bt1=v.findViewById(R.id.vk_f5); final Button bt2=v.findViewById(R.id.vk_right); final Button bt3=v.findViewById(R.id.vk_left); final Button bt4=v.findViewById(R.id.vk_esc); bt1.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { socketClient=new SocketClient(ip,Integer.parseInt(port),handler); socketClient.work("key:vk_f5,vk_f5"); }}); bt2.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { socketClient=new SocketClient(ip,Integer.parseInt(port),handler); socketClient.work("key:vk_right,vk_right"); }}); bt3.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { socketClient=new SocketClient(ip,Integer.parseInt(port),handler); socketClient.work("key:vk_left,vk_left"); }}); bt4.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { socketClient=new SocketClient(ip,Integer.parseInt(port),handler); socketClient.work("key:vk_escape,vk_escape"); }}); bl.setView(v); bl.setPositiveButton("OK", new DialogInterface.OnClickListener() { @Override public void onClick(DialogInterface dialog, Int which) {String s = "Slide control mode turned off "; Toast.makeText(context,s,Toast.LENGTH_SHORT).show(); }}); bl.create().show(); }Copy the code

Add listener returned by key command in handler

Else if(fp== socketClient.server_msg_key){show_msg_settext (" execute KEY successfully "); }Copy the code

The key hot-key operation is implemented.
