悬浮菜单+虚拟按键

1.首先控制悬浮窗要用service

2.悬浮窗的参数

        if (wm == null)
            wm = (WindowManager) getApplicationContext().getSystemService("window");
        if (ballWmParams == null) {
            ballWmParams = new WindowManager.LayoutParams();// ((MyApplication)
                                                            // getApplication()).getMywmParams();
            ballWmParams.type = WindowManager.LayoutParams.TYPE_PHONE;
            ballWmParams.flags |= WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;
            ballWmParams.gravity = Gravity.LEFT | Gravity.TOP;
            ballWmParams.x = 50;
            ballWmParams.y = 50;
            ballWmParams.width = WindowManager.LayoutParams.WRAP_CONTENT;
            ballWmParams.height = WindowManager.LayoutParams.WRAP_CONTENT;
            ballWmParams.format = PixelFormat.RGBA_8888;
            // 添加显示层
        }
        wm.addView(ballView, ballWmParams);

移除的时候要wm.removeViewImmediate(v);

3.LinearLayout的边框，用drawable类型的xml画出

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >

    <gradient
        android:angle="180"
        android:centerX="5"
        android:centerY="5"
        android:endColor="#22080808"
        android:gradientRadius="100"
        android:startColor="#ddffffff"
        android:type="radial" />

    <stroke
        android:dashWidth="2dp"
        android:width="2dp"
        android:color="#99ffffff" />

    <corners android:radius="5dp" />
    <!-- <solid android:color="#11ffffff" /> -->
    <padding
        android:bottom="1dp"
        android:left="1dp"
        android:right="1dp"
        android:top="1dp" />

</shape>

---------------------------------------------虚拟按键

分为两种思路，一种是使用系统签名+反射机制，一种是root
前一种，如果有签名的很方便，后一种可以适用大多是机型。


1.反射方法调用按键，反射+签名+特殊权限+平台编译
<uses-permission android:name="android.permission.INJECT_EVENTS" />

void test() {

        new Thread() {
            public void run() {
                KeyEvent keyEventDown = new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_BACK);
                KeyEvent keyEventUp = new KeyEvent(KeyEvent.ACTION_UP, KeyEvent.KEYCODE_BACK);
                final int repeatCount = (KeyEvent.FLAG_VIRTUAL_HARD_KEY & KeyEvent.FLAG_LONG_PRESS) != 0 ? 1 : 0;
                final KeyEvent evDown = new KeyEvent(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(),
                        KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_BACK, repeatCount, 0, KeyCharacterMap.VIRTUAL_KEYBOARD,
                        0, KeyEvent.FLAG_VIRTUAL_HARD_KEY | KeyEvent.FLAG_FROM_SYSTEM | KeyEvent.FLAG_VIRTUAL_HARD_KEY,
                        InputDevice.SOURCE_KEYBOARD);

                final KeyEvent evUp = new KeyEvent(SystemClock.uptimeMillis(), SystemClock.uptimeMillis(),
                        KeyEvent.ACTION_UP, KeyEvent.KEYCODE_BACK, repeatCount, 0, KeyCharacterMap.VIRTUAL_KEYBOARD, 0,
                        KeyEvent.FLAG_VIRTUAL_HARD_KEY | KeyEvent.FLAG_FROM_SYSTEM | KeyEvent.FLAG_VIRTUAL_HARD_KEY,
                        InputDevice.SOURCE_KEYBOARD);

                Class<?> ClassInputManager;
                try {
                    ClassInputManager = Class.forName("android.hardware.input.InputManager");
                    Method[] methods = ClassInputManager.getMethods();
                    System.out.println("cchen " + Arrays.toString(methods));
                    Method methodInjectInputEvent = null;
                    Method methodGetInstance = null;
                    for (Method method : methods) {
                        System.out.println("cchen " + method.getName());
                        if (method.getName().contains("getInstance")) {
                            methodGetInstance = method;
                        }
                        if (method.getName().contains("injectInputEvent")) {
                            methodInjectInputEvent = method;
                        }
                    }
                    Object instance = methodGetInstance.invoke(ClassInputManager, null);
                    boolean bool = InputManager.class.isInstance(instance);
                    System.out.println("cchen  -- " + bool);
                    // methodInjectInputEvent =
                    // InputManager.getMethod("injectInputEvent",
                    // KeyEvent.class, Integer.class);
                    methodInjectInputEvent.invoke(instance, evDown, 0);
                    methodInjectInputEvent.invoke(instance, evUp, 0);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
        }.start();
    }

2.root方式

获得root权限，模拟在android机器上在shell中输入命令模拟按键

代码源于这里：
[url]http://leoly-fullnexus4.googlecode.com/svn/trunk/FullNexus4/[/url]

要导入其中的类库。

            // String apkRoot="chmod 777 "+getPackageCodePath();
            // RootCommand(apkRoot);
            // full();

   public static boolean RootCommand(String command) {
        Process process = null;
        DataOutputStream os = null;
        try {
            process = Runtime.getRuntime().exec("su");
            os = new DataOutputStream(process.getOutputStream());
            os.writeBytes(command + "\n");
            os.writeBytes("exit\n");
            os.flush();
            process.waitFor();
        } catch (Exception e) {
            Log.d("*** DEBUG ***", "ROOT REE" + e.getMessage());
            return false;
        } finally {
            try {
                if (os != null) {
                    os.close();
                }
                process.destroy();
            } catch (Exception e) {
            }
        }
        Log.d("*** DEBUG ***", "Root SUC ");
        return true;
    }

    private void full() {
        try {
            InputShell localInputShell = getInputShell();
            String str1 = "keycode " + KeyEvent.KEYCODE_BACK;
            localInputShell.runCommand(str1);
        } catch (Exception localException) {
            String str2 = localException.getMessage();
            Log.e("Button Savior", str2);
            localException.printStackTrace();
        }
    }

    public InputShell getInputShell() throws Exception {
        String str1 = null;
        InputStream localInputStream = null;
        FileOutputStream localFileOutputStream = null;
        byte[] arrayOfByte = new byte[4096];
        InputShell localInputShell1 = this.mInputShell;
        AssetManager localAssetManager;
        File localFile;
        int m;
        if (localInputShell1 == null) {
            localAssetManager = this.getApplicationContext().getResources().getAssets();
            str1 = this.getApplicationContext().getFilesDir().getAbsolutePath();
            int i = Build.VERSION.SDK_INT;
            if (i > 15) {
                Log.d("button", "using JB code");
                String str2 = str1 + "/input2_jb.jar";
                localFile = new File(str2);
                str2 = "input2_jb.jar";
                localInputStream = localAssetManager.open(str2);
            } else if (i > 10 && i < 16) {
                String str2 = str1 + "/input2_hc.jar";
                localFile = new File((String) str2);
                str2 = "input2_hc.jar";
                localInputStream = localAssetManager.open(str2);
            } else {
                String str2 = str1 + "/input2.jar";
                localFile = new File(str2);
                str2 = "input2.jar";
                localInputStream = localAssetManager.open(str2);
            }

            localFileOutputStream = new FileOutputStream(localFile);
            m = localInputStream.read(arrayOfByte);
            if (m == -1)
                return null;
            localFileOutputStream.write(arrayOfByte, 0, m);
            localFileOutputStream.close();
            localInputStream.close();
            this.mInputShell = new InputShell("su", str1);
        }
        return this.mInputShell;
    }
