我正在使用本教程，并且收到错误：对于onConnectionFailed类中的ConnectionResult类型，未定义方法getIntentSender（）。 我想点击按钮
整合Google Plus以下是完整代码：

}
}
}
@Override

if (requestCode == RC_SIGN_IN) {

}
}
}

尝试以下代码：
private static final int REQUEST_CODE_RESOLVE_ERR = 9000;
private static final int REQUEST_CODE_SHARE = 1000;
private PlusClient mPlusClient;
private PlusClient.Builder mPlusClientBuilder;
private PlusShare.Builder mPlusShareBuilder;
//In your onCreate method write below code:
mPlusClientBuilder = new Builder(this, this, this);
mPlusClientBuilder.setScopes(Scopes.PLUS_LOGIN, Scopes.PROFILE);
mPlusClient = mPlusClientBuilder.build();
mPlusClient.connect();
//OnActivityResult method:
@Override
protected void onActivityResult(int requestCode, int responseCode, Intent data) {
super.onActivityResult(requestCode, responseCode, data);
if (requestCode == REQUEST_CODE_RESOLVE_ERR && responseCode == RESULT_OK) {
mPlusClient.disconnect();
mPlusClient.connect();
} else if (requestCode == REQUEST_CODE_SHARE && responseCode == RESULT_OK) {
finish();
}
}
//OnConnectionFailed method:
@Override
public void onConnectionFailed(ConnectionResult result) {
if (result.hasResolution()) {
// The user clicked the sign-in button already. Start to resolve
// connection errors. Wait until onConnected() to dismiss the
// connection dialog.
try {
result.startResolutionForResult(this, REQUEST_CODE_RESOLVE_ERR);
} catch (SendIntentException e) {
mPlusClient.disconnect();
mPlusClient.connect();
}
}
}
//OnConnected method:
@Override
public void onConnected(Bundle arg0) {
String accountName = mPlusClient.getAccountName();
}
//SignIn Button click:
btnSignIn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
if (!mPlusClient.isConnected() && btnSignIn.getText().equals(getString(R.string.signin))) {
mPlusClient.connect();
} else if (mPlusClient.isConnected() && btnSignIn.getText().equals(getString(R.string.signout))) {
mPlusClient.clearDefaultAccount();
mPlusClient.disconnect();
}
}
});
// Share on google plus button click event:
btnShare.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if (mPlusClient.isConnected()) {
mPlusShareBuilder = new PlusShare.Builder(getApplicationContext());
mPlusShareBuilder.setType("text/plain");
mPlusShareBuilder.setText(IN_SHARE_MESSAGE + IN_SHARE_LINK);
mPlusShareBuilder.setContentUrl(Uri.parse(IN_SHARE_LINK));
// Intent shareIntent =
// PlusShare.Builder.from(YOUR ACTIVITY.this).setText().setType("text/plain").setContent(Uri.parse("http://example.com/cheesecake/lemon"))
// .getIntent();
Intent shareIntent = mPlusShareBuilder.getIntent();
startActivityForResult(shareIntent, REQUEST_CODE_SHARE);
} else {
//print failure message here
}
}
});
