Question

我已成功创建了一个google + signin按钮。我已经关注link谷歌开发者网站程序。但是，当我点击按钮时，没有任何事情发生。我在下面附上了代码

GoogleAcivity.java

    public abstract class GoogleActivity extends Activity implements OnClickListener,
        ConnectionCallbacks, OnConnectionFailedListener {
    private static final String TAG = "ExampleActivity";
    private static final int REQUEST_CODE_RESOLVE_ERR = 9000;

    private ProgressDialog mConnectionProgressDialog;
    private PlusClient mPlusClient;
    private ConnectionResult mConnectionResult;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);


        mPlusClient = new PlusClient.Builder(this, this, this)
                .setActions("http://schemas.google.com/AddActivity", "http://schemas.google.com/BuyActivity")
                .setScopes(Scopes.PLUS_LOGIN)  // recommended login scope for social features
                // .setScopes("profile")       // alternative basic login scope
                .build();
        findViewById(R.id.sign_in_button).setOnClickListener(this);

        // Progress bar to be displayed if the connection failure is not resolved.
        mConnectionProgressDialog = new ProgressDialog(this);
        mConnectionProgressDialog.setMessage("Signing in...");
            }

    @Override
    public void onClick(View view) {
        if (view.getId() == R.id.sign_in_button && !mPlusClient.isConnected()) {
            if (mConnectionResult == null) {
                mConnectionProgressDialog.show();
            } else {
                try {
                    mConnectionResult.startResolutionForResult(this, REQUEST_CODE_RESOLVE_ERR);
                } catch (SendIntentException e) {

                    // Try connecting again.
                    mConnectionResult = null;
                    mPlusClient.connect();
                }
            }
        }
    }
    @Override
    protected void onStart() {
        super.onStart();
        mPlusClient.connect();
    }

    @Override
    protected void onStop() {
        super.onStop();
        mPlusClient.disconnect();
    }

    @Override
    public void onConnectionFailed(ConnectionResult result) {
      if (mConnectionProgressDialog.isShowing()) {
        // The user clicked the sign-in button already. Start to resolve
        // connection errors. Wait until onConnected() to dismiss the
        // connection dialog.
        if (result.hasResolution()) {
          try {
                   result.startResolutionForResult(this, REQUEST_CODE_RESOLVE_ERR);
           } catch (SendIntentException e) {
                   mPlusClient.connect();
           }
        }
      }
      // Save the result and resolve the connection failure upon a user click.
      mConnectionResult = result;
    }

    @Override
    protected void onActivityResult(int requestCode, int responseCode, Intent intent) {
        if (requestCode == REQUEST_CODE_RESOLVE_ERR && responseCode == RESULT_OK) {
            mConnectionResult = null;
            mPlusClient.connect();
        }
    }


    @Override
    public void onConnected(Bundle connectionHint) {
        String accountName = mPlusClient.getAccountName();
        Toast.makeText(this, accountName + " is connected.", Toast.LENGTH_LONG).show();
    }

    @Override
    public void onDisconnected() {
        Log.d(TAG, "disconnected");
    }
}

我在代码中遗漏了什么。请帮忙..

Answer 1

TAG ="ExampleActivity" "ExampleActivity"应该是GoogleActivity。

Answer 2

 public abstract class GoogleActivity extends Activity implements OnClickListener,
        ConnectionCallbacks, OnConnectionFailedListener {
    private static final String TAG = "ExampleActivity";
    private static final int REQUEST_CODE_RESOLVE_ERR = 9000;

    private ProgressDialog mConnectionProgressDialog;
    private PlusClient mPlusClient;
    private ConnectionResult mConnectionResult;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);


        mPlusClient = new PlusClient.Builder(this, this, this)
                .setActions("http://schemas.google.com/AddActivity", "http://schemas.google.com/BuyActivity")
                .setScopes(Scopes.PLUS_LOGIN)  // recommended login scope for social features
                // .setScopes("profile")       // alternative basic login scope
                .build();
        findViewById(R.id.sign_in_button).setOnClickListener(this);

        // Progress bar to be displayed if the connection failure is not resolved.
        mConnectionProgressDialog = new ProgressDialog(this);
        mConnectionProgressDialog.setMessage("Signing in...");
            }

    @Override
    public void onClick(View view) {
        if (view.getId() == R.id.sign_in_button && !mPlusClient.isConnected()) {
            if (mConnectionResult == null) {
                mConnectionProgressDialog.show();
            } else {
