Question

请原谅我，如果我完全忽略了这里的明显，但我似乎无法从代码中找出如何区分smartWatch 1和smartWatch 2.硬件和显示尺寸似乎有些差异我想说明这一点。 Soo ...如果有人知道如何获得当前的手表显示尺寸，或者确定当前的手表是SmartWatch 1还是2，我会非常感激!!! \ / p>

这是我尝试过的，但是对于这两款手表来说，似乎总是返回220x176

public static int getSupportedControlWidth(Context context) {
    return context.getResources().getDimensionPixelSize(R.dimen.smart_watch_2_control_width);
}

public static int getSupportedControlHeight(Context context) {
    return context.getResources().getDimensionPixelSize(R.dimen.smart_watch_2_control_height);
}

Answer 1

查看SampleControlExtension项目并了解它的用途：

DeviceInfoHelper.isSmartWatch2ApiAndScreenDetected()

但如果你愿意的话，你可以随时随地打电话。

这是SampleExtensionService决定SW1或SW2的方式：

@Override
public ControlExtension createControlExtension(String hostAppPackageName) {
    // First we check if the API level and screen size required for
    // SampleControlSmartWatch2 is supported
    boolean advancedFeaturesSupported = DeviceInfoHelper.isSmartWatch2ApiAndScreenDetected(
            this, hostAppPackageName);
    if (advancedFeaturesSupported) {
        return new SampleControlSmartWatch2(hostAppPackageName, this, new Handler());
    } else {
        // If not we return an API level 1 control based on screen size
        final int controlSWWidth = SampleControlSmartWatch.getSupportedControlWidth(this);
        final int controlSWHeight = SampleControlSmartWatch.getSupportedControlHeight(this);
        final int controlSWHPWidth = SampleControlSmartWirelessHeadsetPro
                .getSupportedControlWidth(this);
        final int controlSWHPHeight = SampleControlSmartWirelessHeadsetPro
                .getSupportedControlHeight(this);

        for (DeviceInfo device : RegistrationAdapter.getHostApplication(this,
                hostAppPackageName)
                .getDevices()) {
            for (DisplayInfo display : device.getDisplays()) {
                if (display.sizeEquals(controlSWWidth, controlSWHeight)) {
                    return new SampleControlSmartWatch(hostAppPackageName, this, new Handler());
                } else if (display.sizeEquals(controlSWHPWidth, controlSWHPHeight)) {
                    return new SampleControlSmartWirelessHeadsetPro(hostAppPackageName, this,
                            new Handler());
                }
            }
        }
        throw new IllegalArgumentException("No control for: " + hostAppPackageName);
    }
}

就个人而言，我发现不需要使用资源，所以这就是我选择这样做的方式。我定义了enum，我使用与上面查询类似的代码isSmartWatch2ApiAndScreenDetected然后传递正确的枚举值。

import android.graphics.Bitmap.Config;

public enum ScreenConfiguration {

    SMARTWATCH1(128, 128, Config.RGB_565), SMARTWATCH2(220, 176, Config.RGB_565);

    private final int mWidth;
    private final int mHeight;
    private final Config mBitmapConfig;

    private ScreenConfiguration(int width, int height, Config bitmapConfig) {
        mWidth = width;
        mHeight = height;
        mBitmapConfig = bitmapConfig;
    }

    public int getWidth() {
        return mWidth;
    }

    public int getHeight() {
        return mHeight;
    }

    public Config getBitmapConfig() {
        return mBitmapConfig;
    }

}

编辑您必须告诉系统您要支持智能手表2.

在RegistrationInformation课程中：

@Override
public int getTargetControlApiVersion() {
    return 2;
}

如果是1，那么isSmartWatch2ApiAndScreenDetected只会出错。

编辑第2部分如何使用枚举

@Override
public ControlExtension createControlExtension(String hostAppPackageName) {
    // First we check if the API level and screen size required for
    // SampleControlSmartWatch2 is supported
    boolean advancedFeaturesSupported = DeviceInfoHelper.isSmartWatch2ApiAndScreenDetected(
            this, hostAppPackageName);
    if (advancedFeaturesSupported) {
        return new SampleControlSmartWatch(ScreenConfiguration.SMARTWATCH2, hostAppPackageName, this, new Handler());
    } else {
        // If not we return an API level 1 control based on screen size
        final int controlSWWidth = SampleControlSmartWatch.getSupportedControlWidth(this);
        final int controlSWHeight = SampleControlSmartWatch.getSupportedControlHeight(this);
        final int controlSWHPWidth = SampleControlSmartWirelessHeadsetPro
                .getSupportedControlWidth(this);
        final int controlSWHPHeight = SampleControlSmartWirelessHeadsetPro
                .getSupportedControlHeight(this);

        for (DeviceInfo device : RegistrationAdapter.getHostApplication(this,
                hostAppPackageName)
                .getDevices()) {
            for (DisplayInfo display : device.getDisplays()) {
                if (display.sizeEquals(controlSWWidth, controlSWHeight)) {
                    return new SampleControlSmartWatch(ScreenConfiguration.SMARTWATCH1, hostAppPackageName, this, new Handler());
                } else if (display.sizeEquals(controlSWHPWidth, controlSWHPHeight)) {
                    return new SampleControlSmartWirelessHeadsetPro(hostAppPackageName, this,
                            new Handler());
                }
            }
        }
        throw new IllegalArgumentException("No control for: " + hostAppPackageName);
    }
}

与第一个示例大致相同，但是看看我如何使用相同的控件类SampleControlSmartWatch并将ScreenConfiguration enum传递给它，因此它可以知道宽度和高度。

Answer 2

要获取SmartWatch 1的屏幕尺寸，您需要使用R.dimen.smart_watch_control_width作为宽度，R.dimen.smart_watch_control_height作为高度。

Answer 3

好的，我刚刚找到了一种方法来完成这项工作！我打开了我的SampleExtensionService.java文件，并从CreateControlExtension函数中捕获了hotAppPackageName。基本上我更新了SampleExtensionService.java，就像这样工作：

public static String hostPackage = "";
@Override
public ControlExtension createControlExtension(String hostAppPackageName) {
    hostPackage = hostAppPackageName;
    return new SampleSensorControl(hostAppPackageName, this);
}

现在我只需从SampleExtenionService调用hostPackage：

String pkg = SampleExtensionService.hostAppPackageName

现在返回com.sonymobile.smartwatch2或com.sonyericsson.extras.smartwatch

似乎对我有用!!希望能帮到别人！

------------编辑-------------

好的，所以我现在觉得自己像个白痴！我正在创建一个控件扩展，在初始化步骤中就是hostAppPackageName

SampleSensorControl(final String hostAppPackageName, final Context context) {

： - 0 !!!!!我会留下我的初步答案，以防它对其他人有用。

获取SmartWatch 1和2显示大小或区分两者
