android自动息屏时间修改,Android

Android 永不锁屏，开机不锁屏，删除设置中休眠时间选项

Android 6.0.1

1.Settings 删掉屏幕待机选项

packages/apps/Settings/res/xml/display_settings.xml

注释掉这个ListPreference

packages/apps/Settings/src/com/android/settings/DisplaySettings.java

添加if条件，如果没有找到这个preference就不执行相关操作；具体可以参考被隐藏的 night_mode

mScreenTimeoutPreference = (ListPreference) findPreference(KEY_SCREEN_TIMEOUT);

if (mScreenTimeoutPreference !=null ) {

final long currentTimeout = Settings.System.getLong(resolver, SCREEN_OFF_TIMEOUT,

FALLBACK_SCREEN_TIMEOUT_VALUE);

mScreenTimeoutPreference.setValue(String.valueOf(currentTimeout));

mScreenTimeoutPreference.setOnPreferenceChangeListener(this);

disableUnusableTimeouts(mScreenTimeoutPreference);

updateTimeoutPreferenceDescription(currentTimeout);

}

2.禁止锁屏
