android 13MTK平台禁止状态栏下拉
最近在搞android13的项目，之前搞过android11的Systemui禁止下拉，想着应该可以直接移植过去。直到开始着手修改发现11到13的变化还是挺大的，很多类都找不到了。于是又重新研究了下，好了废话不多说。
1.解锁状态下禁止Syatemui下拉
代码路径：\SystemUI\src\com\android\systemui\statusbar\CommandQueue.java
public boolean panelsEnabled() {
//KingYan 注释掉现有的返回 默认返回false
return false;
/** KingYan 注释掉以下代码
final int disabled1 = getDisabled1(DEFAULT_DISPLAY);
final int disabled2 = getDisabled2(DEFAULT_DISPLAY);
return (disabled1 & StatusBarManager.DISABLE_EXPAND) == 0
&& (disabled2 & StatusBarManager.DISABLE2_NOTIFICATION_SHADE) == 0
&& !ONLY_CORE_APPS;*/
}2.禁止解锁状态下在Launcher空白区域下拉
代码路径：SystemUI/src/com/android/systemui/recents/OverviewProxyService.java
@Override
public void onStatusBarMotionEvent(MotionEvent event) {
// KingYan 注释掉以下代码
/* verifyCallerAndClearCallingIdentity("onStatusBarMotionEvent", () -> {
mCentralSurfacesOptionalLazy.get().ifPresent(centralSurfaces -> {
if (event.getActionMasked() == ACTION_DOWN) {
centralSurfaces.getPanelController().startExpandLatencyTracking();
}
mHandler.post(() -> {
int action = event.getActionMasked();
if (action == ACTION_DOWN) {
mInputFocusTransferStarted = true;
mInputFocusTransferStartY = event.getY();
mInputFocusTransferStartMillis = event.getEventTime();
centralSurfaces.onInputFocusTransfer(
mInputFocusTransferStarted, false *//* cancel *//*,
0 *//* velocity *//*);
}
if (action == ACTION_UP || action == ACTION_CANCEL) {
mInputFocusTransferStarted = false;
float velocity = (event.getY() - mInputFocusTransferStartY)
/ (event.getEventTime() - mInputFocusTransferStartMillis);
centralSurfaces.onInputFocusTransfer(mInputFocusTransferStarted,
action == ACTION_CANCEL,
velocity);
}
event.recycle();
});
});
});*/
