android - 获取SmartWatch 1和2的显示尺寸或区分两者

如果我完全忽略了这里的明显内容，请原谅我，但是我似乎无法从代码中找出如何区分smartWatch 1和smartWatch2。在硬件和显示尺寸上似乎有些差异，我想来说明这一点。太...如果有人知道如何获取当前手表的显示尺寸，或者确定当前手表是SmartWatch 1还是2，我将不胜感激！

这是我尝试过的方法，但对于两块手表，它似乎总是返回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);
}

最佳答案

查看SampleControlExtension项目，并查看其用法：

DeviceInfoHelper.isSmartWatch2ApiAndScreenDetected()

但是，您可以根据需要随时随地致电。

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);
    }
}

我个人认为资源的使用是不必要的，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isSmartWatch2ApiAndScreenDetected相似的代码，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要支持smartwatch 2。

在您的RegistrationInformation类中：

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

如果是1，则对于isSmartWatch2ApiAndScreenDetected您只会得到false。

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);
    }
}

基本上与第一个示例相同，但是请参见如何使用相同的控件类SampleControlSmartWatch并将ScreenConfiguration enum传递给它，以便它可以知道宽度和高度。
