Android 应用程序中-设置-蓝牙，隐藏蓝牙功能

Android 应用程序中-设置-蓝牙要隐藏蓝牙功能步骤如

1.通过搜索">Bluetooth<"找到相关的定义

Settings\res\values\String.xml

./res/values/strings.xml:206:    <string name="bluetooth">Bluetooth</string>

./res/values/strings.xml:958:    <string name="bluetooth_quick_toggle_title">Bluetooth</string>

./res/values/strings.xml:962:    <string name="bluetooth_settings">Bluetooth</string>

./res/values/strings.xml:964:    <string name="bluetooth_settings_title">Bluetooth</string>

./res/values/strings.xml:2940:    <string name="power_bluetooth">Bluetooth</string>

2.通过bluetooth_settings定义名字找到相关的xml文件

Settings\res\xml\settings_headers.xml

<!-- Bluetooth -->

    <header

        android:id="@+id/bluetooth_settings"

        android:fragment="com.android.settings.bluetooth.BluetoothSettings"

        android:title="@string/bluetooth_settings_title"

        android:icon="@drawable/ic_settings_bluetooth2" />

3.通过ID，@+id/bluetooth_settings（R.id.bluetooth_settings）找到相关的Java文件

Settings\src\com\android\settings\Settings.java

private void updateHeaderList(List<Header> target) {//更新Header列表

    if (id == R.id.bluetooth_settings) {
                // Remove Bluetooth Settings if Bluetooth service is not available.
                if (!getPackageManager().hasSystemFeature(PackageManager.FEATURE_BLUETOOTH)) {
                    target.remove(header);
                }

改为：当为真的时候都去移除蓝色选项

    if (id == R.id.bluetooth_settings) {
                // Remove Bluetooth Settings if Bluetooth service is not available.
                if (!getPackageManager().hasSystemFeature(PackageManager.FEATURE_BLUETOOTH)) {
                    target.remove(header);
                }
