今天我们接着昨天的继续
1、实现控制球的点击拖动
2、点击控制球后弹出菜单选择界面
3、菜单选择功能
其实这几个都不难，思路如下：1、要实现我们的控制球悬浮在所有App界面之上：通过WindowManager来设置App的显示方式
2、控制球的拖动：重写onTouchListener即可，这个相信很多人都做过了
3、弹出菜单界面和菜单选择功能：这个就是一个比较好看的PopupWindow
通过这几条分析，我们可以发现，这个项目其实还是比较简单的哈，所以说，我一直坚信的，思路很重要
下面我们一点点来实现吧：so easy
程序核心必然是一个Service，相信我不要多说了：
MainService：
package com.xys.xtouchassistant.service;import com.xys.xtouchassistant.R;import android.app.Service;import android.content.Context;import android.content.Intent;import android.graphics.Color;import android.graphics.PixelFormat;import android.graphics.drawable.ColorDrawable;import android.graphics.drawable.Drawable;import android.os.IBinder;import android.provider.Settings;import android.util.DisplayMetrics;import android.view.Gravity;import android.view.LayoutInflater;import android.view.MotionEvent;import android.view.View;import android.view.View.OnClickListener;import android.view.View.OnTouchListener;import android.view.WindowManager;import android.widget.Button;import android.widget.PopupWindow;import android.widget.TextView;import android.widget.Toast;public class MainService extends Service implements OnClickListener, OnTouchListener { // 控制球View private View touchBallView; // 弹出菜单View private View menuView; // 控制球 private Button touchBall; // WindowManager WindowManager wm; // WindowManagerParams WindowManager.LayoutParams params; private PopupWindow popup; // 点击坐标 private float x, y; private float touchX, touchY; // 移动Flag private boolean isMoving; // Menu上的组件 private TextView tvApps; private TextView tvHomeScreen; private TextView tvSetting; private TextView tvLockScreen; private TextView tvFavor; @Override public void onCreate() { super.onCreate(); // 初始化Views initView(); // 显示TouchBall createTouchBallView(); // 监听事件 regListener(); } /** * 监听事件 */ private void regListener() { touchBall.setOnTouchListener(this); touchBall.setOnClickListener(this); tvApps.setOnClickListener(this); tvHomeScreen.setOnClickListener(this); tvSetting.setOnClickListener(this); tvLockScreen.setOnClickListener(this); tvFavor.setOnClickListener(this); } /** * 初始化Views */ private void initView() { // 加载控制球View touchBallView = LayoutInflater.from(this).inflate(R.layout.touch_ball, null); touchBall = (Button) touchBallView.findViewById(R.id.touch_ball); // 初始化MenuView menuView = LayoutInflater.from(this).inflate(R.layout.shown_menu, null); tvApps = (TextView) menuView.findViewById(R.id.tv_apps); tvHomeScreen = (TextView) menuView.findViewById(R.id.tv_home_screen); tvSetting = (TextView) menuView.findViewById(R.id.tv_setting); tvLockScreen = (TextView) menuView.findViewById(R.id.tv_lock_screen); tvFavor = (TextView) menuView.findViewById(R.id.tv_favor); } /** * 显示TouchBall */ private void createTouchBallView() { wm = (WindowManager) getSystemService(Context.WINDOW_SERVICE); params = new WindowManager.LayoutParams(); params.type = WindowManager.LayoutParams.TYPE_PHONE; params.flags = WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE; params.gravity = Gravity.LEFT | Gravity.TOP; params.x = 0; params.y = 0; params.width = WindowManager.LayoutParams.WRAP_CONTENT; params.height = WindowManager.LayoutParams.WRAP_CONTENT; params.format = PixelFormat.RGBA_8888; wm.addView(touchBallView, params); } @Override public IBinder onBind(Intent intent) { return null; } @Override public void onClick(View v) { switch (v.getId()) { case R.id.touch_ball: // 显示Popup菜单 showMenuWindow(); break; case R.id.tv_apps: // 显示Apps菜单 Toast.makeText(this, "APPS", Toast.LENGTH_SHORT).show(); popup.dismiss(); break; case R.id.tv_favor: Toast.makeText(this, "FAVOR", Toast.LENGTH_SHORT).show(); popup.dismiss(); break; case R.id.tv_home_screen: // 显示主菜单 Toast.makeText(this, "HOME", Toast.LENGTH_SHORT).show(); popup.dismiss(); break; case R.id.tv_lock_screen: // 锁屏 Toast.makeText(this, "LOCK", Toast.LENGTH_SHORT).show(); popup.dismiss(); break; case R.id.tv_setting: // 显示Setting界面 Toast.makeText(this, "SETTING", Toast.LENGTH_SHORT).show(); popup.dismiss(); break; default: popup.dismiss(); break; } } /** * 显示Popup菜单 */ private void showMenuWindow() { DisplayMetrics dm = getResources().getDisplayMetrics(); popup = new PopupWindow(menuView, (int) (dm.widthPixels * 0.7), (int) (dm.heightPixels * 0.5)); Drawable transpent = new ColorDrawable(Color.TRANSPARENT); popup.setBackgroundDrawable(transpent); popup.setFocusable(true); popup.setOutsideTouchable(true); popup.showAtLocation(touchBallView, Gravity.CENTER, 0, 0); popup.update(); } /** * Touch监听事件 */ @Override public boolean onTouch(View v, MotionEvent event) { x = event.getRawX(); y = event.getRawY(); // 触摸事件 switch (event.getAction()) { case MotionEvent.ACTION_DOWN: isMoving = false; // 触摸坐标赋值 touchX = event.getX(); touchY = event.getY(); break; case MotionEvent.ACTION_MOVE: isMoving = true; // 触摸坐标赋值 params.x = (int) (x - touchX); params.y = (int) (y - touchY); wm.updateViewLayout(touchBallView, params); break; case MotionEvent.ACTION_UP: // 触摸坐标赋值 touchX = touchY = 0; break; default: break; } if (isMoving) { return true; } else { return false; } }}开启Service的主程序：
MainActivity：
package com.xys.xtouchassistant.activity;import com.xys.xtouchassistant.R;import com.xys.xtouchassistant.service.MainService;import android.os.Bundle;import android.app.Activity;import android.content.Intent;public class MainActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); Intent service = new Intent(); service.setClass(this, MainService.class); startService(service); }}这里只是简单的用一个Activity去开启这个服务，后面我们会重新实现开启服务的方法：
1、通过注册一个开机广播事件去开启我们的服务
2、通过进程守护来实现我们的Service不被kill（也可以通过在通知面板显式显示服务的方式来防止被kill）
3、实现菜单界面功能的可配置化
ps：需要源码的请留意哦
