SystemUI问题修改总结二

案例一：Launcher界面下滑启动下拉栏

android5.0上可以直接使用

private StatusBarManager mStatusBarManager = null;

mStatusBarManager = (StatusBarManager) getSystemService(Context.STATUS_BAR_SERVICE);

mStatusBarManager.expandNotificationsPanel(); //半展开

mStatusBarManager.expandSettingsPanel();//全展开

android6.0上用上面两个方法下拉速度较慢，只能通过广播来实现

SystemUI\src\com\android\systemui\statusbar\phone\NotificationPanelView.java中添加

public void expandWithQsQuickly() {

if (mQsExpansionEnabled) {

mQsExpandImmediate = true;

}

expandQuickly();

}

public void expandQuickly() {

if (isFullyCollapsed()) {

mBar.startOpeningPanel(this);

notifyExpandingStarted();

fling(15000.0f, true /* expand */);

} else if (DEBUG) {

}

}

SystemUI\src\com\android\systemui\statusbar\phone\PhoneStatusBar.java中添加

public void animateExpandSettingsPanelQuickly() {

if (!panelsEnabled()) {

return;

}

// Settings are not available in setup

if (!mUserSetup) return;

mNotificationPanel.expandWithQsQuickly();

if (false) postStartTracing();

}

然后通过监听广播来调用animateExpandSettingsPanelQuickly方法实现快速伸展

案例二：下拉栏布局及控件具体位置

SystemUI/res/layout/status_bar_expanded_header.xml 下拉栏头部一段布局

SystemUI/res/layout/status_bar_expanded.xml 下拉栏快速设置界面布局

<include layout="@layout/qs_panel" 是快速设置布局

com.android.systemui.statusbar.phone.NotificationsQuickSettingsContainer 是消息和快速设置集装箱的意思

com.android.systemui.statusbar.phone.ObservableScrollView是控制上下滑动的控件

com.android.systemui.statusbar.stack.NotificationStackScrollLayout 是信息提示布局

NotificationStackScrollLayout.java 中的属性mSidePaddings是控制信息宽度的

案例三：锁屏密码

解锁父控件

frameworks\base\packages\Keyguard\src\com\android\keyguard\KeyguardAbsKeyInputView.java

解锁辅助类

frameworks\base\core\java\com\android\internal\widget\LockPatternChecker.java

设置中设置密码锁的时候调用的底层的类

frameworks\base\core\java\com\android\internal\widget\LockPatternUtils.java

设置锁屏密码的地方

SystemUI\packages\apps\Settings\src\com\android\settings\ChooseLockPassword.java

解锁的地方一

frameworks\base\packages\Keyguard\src\com\android\keyguard\KeyguardPasswordView.java

@Override

public void afterTextChanged(Editable s) {

if (!TextUtils.isEmpty(s)) {

onUserInput();

}

}

解锁的地方二

base/packages/Keyguard/src/com/android/keyguard/KeyguardPinBasedInputView.java

mPasswordEntry.setUserActivityListener(new PasswordTextView.UserActivityListener() {

@Override

public void onUserActivity() {

onUserInput();

}

});
