标题: 解决Luancher的overscan设置不一致的问题
1，setDisplayOverscan这个函数起作用的：
这个函数是被谁调用的呢？
2，根据搜索的结果：
base/policy/src/com/android/internal/policy/impl/PhoneWindowManager.java: public void setDisplayOverscan(Display display, int left, int top, int right, int bottom) {
base/core/java/android/view/WindowManagerPolicy.java: public void setDisplayOverscan(Display display, int left, int top, int right, int bottom);
base/services/core/java/com/android/server/wm/WindowManagerService.java:       mPolicy.setDisplayOverscan(displayContent.getDisplay(),

应该是WindowManagerService.java调用的。
private void configureDisplayPolicyLocked(DisplayContent displayContent) {
      mPolicy.setInitialDisplaySize(displayContent.getDisplay(),
            displayContent.mBaseDisplayWidth,
            displayContent.mBaseDisplayHeight,
            displayContent.mBaseDisplayDensity);

      DisplayInfo displayInfo = displayContent.getDisplayInfo();
      mPolicy.setDisplayOverscan(displayContent.getDisplay(),
            displayInfo.overscanLeft, displayInfo.overscanTop,
            displayInfo.overscanRight, displayInfo.overscanBottom);
}

3，继续：
private void setOverscanLocked(DisplayContent displayContent,
         int left, int top, int right, int bottom) {
      final DisplayInfo displayInfo = displayContent.getDisplayInfo();
      synchronized (displayContent.mDisplaySizeLock) {
         displayInfo.overscanLeft = left;
         displayInfo.overscanTop = top;
         displayInfo.overscanRight = right;
         displayInfo.overscanBottom = bottom;
      }

      mDisplaySettings.setOverscanLocked(displayInfo.name, left, top, right, bottom);
      mDisplaySettings.writeSettingsLocked();

      reconfigureDisplayLocked(displayContent);
}

4， @Override
public void setOverscan(int displayId, int left, int top, int right, int bottom) {
      if (mContext.checkCallingOrSelfPermission(
            android.Manifest.permission.WRITE_SECURE_SETTINGS) !=
            PackageManager.PERMISSION_GRANTED) {
         throw new SecurityException("Must hold permission " +
                  android.Manifest.permission.WRITE_SECURE_SETTINGS);
      }
      final long ident = Binder.clearCallingIdentity();
      try {
         synchronized(mWindowMap) {
            DisplayContent displayContent = getDisplayContentLocked(displayId);
            if (displayContent != null) {
                  setOverscanLocked(displayContent, left, top, right, bottom);
            }
         }
      } finally {
         Binder.restoreCallingIdentity(ident);
      }
}

5，继续：
base/cmds/wm/src/com/android/commands/wm/Wm.java

private void runDisplayOverscan() throws Exception {
      String overscanStr = nextArgRequired();
      Rect rect = new Rect();
      int density;
      if ("reset".equals(overscanStr)) {
         rect.set(0, 0, 0, 0);
      } else {
         final Pattern FLATTENED_PATTERN = Pattern.compile(
                  "(-?\\d+),(-?\\d+),(-?\\d+),(-?\\d+)");
         Matcher matcher = FLATTENED_PATTERN.matcher(overscanStr);
         if (!matcher.matches()) {
            System.err.println("Error: bad rectangle arg: " + overscanStr);
            return;
         }
         rect.left = Integer.parseInt(matcher.group(1));
         rect.top = Integer.parseInt(matcher.group(2));
         rect.right = Integer.parseInt(matcher.group(3));
         rect.bottom = Integer.parseInt(matcher.group(4));
      }

      try {
         mWm.setOverscan(Display.DEFAULT_DISPLAY, rect.left, rect.top, rect.right, rect.bottom);
      } catch (RemoteException e) {
      }
}

是这里导致的吗？

debug WMS中间的几个函数有没有被调用过呢？

kernel-3.10/arch/arm64/configs/konka6735_bk929_l_debug_defconfig：：：
中间有：
CONFIG_LCM_HEIGHT="1920"
CONFIG_LCM_WIDTH="1080"
device/konka/konka6735_bk929_l/ProjectConfig.mk：：：
中间有
LCM_HEIGHT = 1920
LCM_WIDTH = 1080
这里参数如果修改会如何呢？

修改这个文件：
/media/doraemon/express/alps_ok/packages/apps/Launcher3/src/com/android/launcher3/Launcher.java
protected void onCreate(Bundle savedInstanceState) {
      if (DEBUG_STRICT_MODE) {
         StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
                  .detectDiskReads()
                  .detectDiskWrites()
                  .detectNetwork() // or .detectAll() for all detectable problems
                  .penaltyLog()
                  .build());
         StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()
                  .detectLeakedSqlLiteObjects()
                  .detectLeakedClosableObjects()
                  .penaltyLog()
                  .penaltyDeath()
                  .build());
      }

      super.onCreate(savedInstanceState);

      /// M: [OP09]Whether Edit and Hide Apps support or not.@{
      mSupportEditAndHideApps = LauncherExtPlugin.getInstance().getWorkspaceExt(
                        this.getApplicationContext()).supportEditAndHideApps();
      //}@

      LauncherAppState.setApplicationContext(getApplicationContext());
      LauncherAppState app = LauncherAppState.getInstance();
      LauncherAppState.getLauncherProvider().setLauncherProviderChangeListener(this);

      /// M: Add for smart book feature. Change DB if UI layout is changed.
      boolean isDatabaseIdChanged = false;
      if (SystemProperties.get("ro.mtk_smartbook_support").equals("1")) {
         int originalDatabaseId = app.getLauncherProvider().getDatabaseId();
         int newDatabaseId = getResources().getInteger(R.integer.database_id);
         if (LauncherLog.DEBUG) {
            LauncherLog.d(TAG, "+++++++++[Smartbook or Phone+++++++++"
      + "\n" + "originalDatabaseId = " + originalDatabaseId
         + "\n" + "newDatabaseId = " + newDatabaseId
      + "\n" + "+++++++++Smartbook or Phone]+++++++++");
         }
         if (originalDatabaseId != newDatabaseId) {
            isDatabaseIdChanged = true;
            app.updateScreenInfo();
            app.getIconCache().flush();
            Utilities.initStatics(this);
            app.getLauncherProvider().setDatabaseId(newDatabaseId);
         }
      }

      // Determine the dynamic grid properties
      Point smallestSize = new Point();
      Point largestSize = new Point();
      Point realSize = new Point();
      Display display = getWindowManager().getDefaultDisplay();
      display.getCurrentSizeRange(smallestSize, largestSize);
      display.getRealSize(realSize);
      DisplayMetrics dm = new DisplayMetrics();
      display.getMetrics(dm);

//zcfdebug++<<
realSize.x=realSize.x/2;
dm.widthPixels=dm.widthPixels/2;
//zcfdebug>>++
      // Lazy-initialize the dynamic grid
      /// M: Add for smart book feature. Force re-init dynamic grid if database ID is changed.
      DeviceProfile grid = app.initDynamicGrid(this,
            Math.min(smallestSize.x, smallestSize.y),
            Math.min(largestSize.x, largestSize.y),
            realSize.x, realSize.y,
            dm.widthPixels, dm.heightPixels, isDatabaseIdChanged);
这样，图标就不乱了
