按下按钮在Arduino上时打电话

Question

嗨，我正在尝试结合2个项目1.告诉我Arduino上的Wen按钮2.打电话给Android

我试图做的是按下按钮在Arduino上打电话。但是没有运气：（

呼叫

    package net.mitchtech.adb;
    import net.mitchtech.adb.simpledigitalinput.R;
    import android.app.Activity;
    import android.content.ActivityNotFoundException;
    import android.content.Intent;
    import android.net.Uri;
    import android.os.Bundle;
    import android.util.Log;
    public class phonecalls extends Activity {
    private void call() {
        try {
            Intent callIntent = new Intent(Intent.ACTION_CALL);
            callIntent.setData(Uri.parse("tel:[phone]"));
            startActivity(callIntent);
        } catch (ActivityNotFoundException activityException) {
            Log.e("dialing-example", "Call failed", activityException);
        }
    }
        /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.input);
        }
    }

按钮

public class ButtonView extends FrameLayout {
    private static final String TAG = ButtonView.class.getSimpleName();
    private final View mButtonView;
    private Server mServer;
    private final int BUTTON1 = 2;
    private final int BUTTON2 = 3;
    public ButtonView(Context context, AttributeSet attrs) {
        super(context, attrs);
        LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        mButtonView = inflater.inflate(R.layout.input, this);
    }
    public void setServer(Server server) {
        mServer = server;
        mServer.addListener(new AbstractServerListener() {
            @Override
            public void onReceive(org.microbridge.server.Client client, byte[] data) {
                if (data.length < 2)
                    return;
                final int pinNumber = data[0];
                final int pinState = data[1];
                Log.i(TAG, "data[0]:" + pinNumber + "  data[1]:" + pinState);
                final TextView positionText = (TextView) findViewById(R.id.activeText);
                class InputAction implements Runnable {
                    public void run() {
                        switch (pinNumber) {
                        case BUTTON1:
                            if (pinState == 1) {
                                call();
                                positionText.setText("Button 1 Active");
                            } else {
                                positionText.setText("");
                            }
                            break;
                        case BUTTON2:
                            if (pinState == 1) {
                                positionText.setText("Button 2 Active");
                            } else {
                                positionText.setText("");
                            }
                            break;
                        default:
                            break;
                        }
                    }
                };
                InputAction action = new InputAction();
                post(action);
            }
        });
    }
    public View getmButtonView() {
        return mButtonView;
    }
}

和另一个活动

package net.mitchtech.adb;
import java.io.IOException;
import net.mitchtech.adb.simpledigitalinput.R;
import org.microbridge.server.Server;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
public class SimpleDigitalInputActivity extends Activity {
    private final static String TAG = SimpleDigitalInputActivity.class.getSimpleName();
    @Override
    public void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Server server = null;
        try
        {
            server = new Server(4567);
            server.start();
            ButtonView buttonView = (ButtonView) findViewById(R.id.inputView);
            buttonView.setServer(server);
            } catch (IOException e)
        {
            Log.e(TAG, "Unable to start TCP server", e);
            System.exit(-1);
        }
    }
}

Answer 1

您的call()功能在您的活动中声明，但是您正在尝试在ButtonView类中访问它。尝试将其移至ButtonView（复制＆amp;粘贴）。
