Question

我想在我的Android应用中放置谷歌登录按钮。我从https://developers.google.com/+/mobile/android/sign-in获取了参考资料，它显示了我的持续进度条，但未登录我的帐户。我已经在模拟器上添加了我的id。我附上它的形象。这是我的代码。

public class MyActivity extends Activity implements GooglePlayServicesClient.ConnectionCallbacks, GooglePlayServicesClient.OnConnectionFailedListener, View.OnClickListener {

    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
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        mPlusClient = new PlusClient.Builder(this, this, this)
                .setActions("http://schemas.google.com/AddActivity", "http://schemas.google.com/BuyActivity")
                .build();
        findViewById(R.id.sign_in_button).setOnClickListener(this);
        mConnectionProgressDialog = new ProgressDialog(this);
        mConnectionProgressDialog.setMessage("Signing in...");
    }


    @Override
    public void onConnected(Bundle bundle) {
        // We've resolved any connection errors.
        mConnectionProgressDialog.dismiss();
        Toast.makeText(this, " User is connected.", Toast.LENGTH_LONG).show();
    }

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

    @Override
    public void onConnectionFailed(ConnectionResult connectionResult) {
        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 (connectionResult.hasResolution()) {
                try {
                    connectionResult.startResolutionForResult(this, REQUEST_CODE_RESOLVE_ERR);
                } catch (IntentSender.SendIntentException e) {
                    mPlusClient.connect();
                }
            }
        }

        // Save the intent so that we can start an activity when the user clicks
        // the sign-in button.
        mConnectionResult = connectionResult;
    }

    @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 (IntentSender.SendIntentException e) {
                    // Try connecting again.
                    mConnectionResult = null;
                    mPlusClient.connect();
                }
            }
        }
    }

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

main.xml中

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:orientation="vertical"
              android:layout_width="fill_parent"

            android:layout_centerVertical="true"

即使在控制台中启用google api后，它也会显示错误谷歌+应用程序已安装在我的设备上。我发布了两张图片。

mPlusClient.connect();未在任何地方被调用。您只是在点击事件中显示进度条而不是尝试连接。

来自Plusclient doc

你应该在Activity的onCreate（Bundle）方法中实例化这个对象，然后在onStart（）中调用connect（），在onStop（）中调用disconnect（），无论状态如何。

尝试在onStart或按钮单击中添加mPlusClient。
