【Android】安卓开机禁止锁屏，禁止屏幕休眠

1.Settings 删掉开机锁屏界面

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

1. <!-- Hide screen sleep

2. <ListPreference

3. android:key="screen_timeout"

4. android:title="@string/screen_timeout"

5. android:summary="@string/screen_timeout_summary"

6. android:persistent="false"

7. android:entries="@array/screen_timeout_entries"

8. android:entryValues="@array/screen_timeout_values" /> -->

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

1. mScreenTimeoutPreference = (ListPreference) findPreference(KEY_SCREEN_TIMEOUT);

2. if (mScreenTimeoutPreference !=null ) {

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

4. FALLBACK_SCREEN_TIMEOUT_VALUE);

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

6. mScreenTimeoutPreference.setOnPreferenceChangeListener(this);

7. disableUnusableTimeouts(mScreenTimeoutPreference);

8. updateTimeoutPreferenceDescription(currentTimeout);

2. 此处设置锁屏以及时间：
frameworks/base/packages/SettingsProvider/res/values/defaults.xml

vendor/mediatek/proprietary/packages/apps/SettingsProvider/res/values/defaults.xml

<bool name="def_lockscreen_disabled">false</bool> 改为 true；即默认禁止锁屏

<integer name="def_screen_off_timeout">6000</integer> 6000改成2147483647，即默认永不灭屏

 

以下是 adb 设置方法

adb shell settings put system screen_off_timeout 2147483647

adb shell settings put system def_lockscreen_disabled true
