如何确定Android设备是否有屏幕，即它是否是Android机顶盒？

Question

I know one can obtain screen sizes, but I would like to know if someone has ever been able to find out if the Android device has a screen or not. ie whether it is a set top box or not.

I guess screen size returned should be "zero", but I am not sure if that is actually the response in the real world.

Thank you.

You can check for a TV device .

public static final String TAG = "DeviceTypeRuntimeCheck";

UiModeManager uiModeManager = (UiModeManager) getSystemService(UI_MODE_SERVICE);
if (uiModeManager.getCurrentModeType() == Configuration.UI_MODE_TYPE_TELEVISION) {
    Log.d(TAG, "Running on a TV Device");
} else {
    Log.d(TAG, "Running on a non-TV Device");
}

In staring of your code paste this code:

    int screenSize = getResources().getConfiguration().screenLayout &
        Configuration.SCREENLAYOUT_SIZE_MASK;

String toastMsg;
switch(screenSize) {
    case Configuration.SCREENLAYOUT_SIZE_LARGE:
        toastMsg = "Large screen";
        break;
    case Configuration.SCREENLAYOUT_SIZE_NORMAL:
        toastMsg = "Normal screen";
        break;
    case Configuration.SCREENLAYOUT_SIZE_SMALL:
        toastMsg = "Small screen";
        break;
    default:
        toastMsg = "Screen size is neither large, normal or small";
}
Toast.makeText(this, toastMsg, Toast.LENGTH_LONG).show();

you can determine screen size by toastMsg .
