我已经按照谷歌播放服务示例在我的 Android 应用程序中添加了一个 PlusOneButton,加号和减号功能到目前为止运行良好。只是当用户通过他们的 +1 网站(在个人资料 -> +1 中)删除加号项目并返回应用程序时,我遇到了一个问题,加号状态不会在我的应用程序中更新,它将保持加号状态。(看起来 Play 商店会将状态更改为 un-plus)。我不知道play store是怎么做的。有人可以给我一些建议吗?还有有什么方法可以像 Play Store 那样实现 +1 功能吗?不必显示弹出对话框。
以下是我的代码:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.plustest);
int errorCode = GooglePlusUtil.checkGooglePlusApp(this);
if(errorCode != GooglePlusUtil.SUCCESS) {
GooglePlusUtil.getErrorDialog(errorCode, this, 0).show();
} else {
// The +1 button does not require scopes.
mPlusClient = new PlusClient.Builder(this, this, this)
.clearScopes()
.build();
}
/*
* The {@link PlusOneButton} can be configured in code, but in this example we
* have set the parameters in the layout.
*
* Example:
* mPlusOneSmallButton.setAnnotation(PlusOneButton.ANNOTATION_INLINE);
* mPlusOneSmallButton.setSize(PlusOneButton.SIZE_MEDIUM);
*/
mPlusOneSmallButton = (PlusOneButton) findViewById(R.id.plus_one_small_button);
mPlusOneMediumButton = (PlusOneButton) findViewById(R.id.plus_one_medium_button);
mPlusOneTallButton = (PlusOneButton) findViewById(R.id.plus_one_tall_button);
mPlusOneStandardButton = (PlusOneButton) findViewById(R.id.plus_one_standard_button);
mPlusOneStandardButtonWithAnnotation = (PlusOneButton) findViewById(
R.id.plus_one_standard_ann_button);
}
@Override
protected void onStart() {
super.onStart();
mPlusClient.connect();
}
@Override
protected void onResume() {
super.onResume();
// Refresh the state of the +1 button each time we receive focus.
mPlusOneSmallButton.initialize(mPlusClient, URL, PLUS_ONE_REQUEST_CODE);
mPlusOneMediumButton.initialize(mPlusClient, URL, this);
mPlusOneTallButton.initialize(mPlusClient, URL, PLUS_ONE_REQUEST_CODE);
mPlusOneStandardButton.initialize(mPlusClient, URL, PLUS_ONE_REQUEST_CODE);
mPlusOneStandardButtonWithAnnotation.initialize(mPlusClient, URL, PLUS_ONE_REQUEST_CODE);
}
@Override
protected void onStop() {
super.onStop();
mPlusClient.disconnect();
}
@Override
public void onClick(View v) {
}
@Override
public void onButtonClick(int id) {
}
@Override
public void onDashboardClick() {
}
@Override
public void onConnected(Bundle bundle) {
String name = mPlusClient.getAccountName();
}
@Override
public void onDisconnected() {
}
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
mConnectionResult = connectionResult;
if(!mPlusClient.isConnected()) {
try {
mConnectionResult.startResolutionForResult(this, PLUS_ONE_REQUEST_CODE);
} catch (IntentSender.SendIntentException e) {
mConnectionResult = null;
mPlusClient.connect();
}
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent){
if(requestCode == PLUS_ONE_REQUEST_CODE && resultCode == RESULT_OK) {
mConnectionResult = null;
mPlusClient.connect();
}
}
@Override
public void onPlusOneClick(Intent intent) {
if(!mPlusClient.isConnected()) {
mPlusClient.connect();
} else {
startActivityForResult(intent, 0);
}
}
