public class DataUploadPresenter {

private static DataUploadPresenter dataUploadPresenter;

private DataUploadPresenter() {

}

public synchronized static DataUploadPresenter getIntstance() {
if (dataUploadPresenter == null) {
dataUploadPresenter = new DataUploadPresenter();
}
return dataUploadPresenter;
}
//上传提醒
public void uploadRemind(final Context context) {
DataRequest.updateRemind(new RequestListener() {

@Override
public void requestFinish(Object result) {
((BaseActivity) context).setResult(Activity.RESULT_OK);
((BaseActivity) context).finish();
((BaseActivity) context).closeLoading();
}

@Override
public void requestNext() {
((BaseActivity) context).setResult(Activity.RESULT_OK);
((BaseActivity) context).finish();
((BaseActivity) context).closeLoading();
}
});
}

//上传案件
public void uploadCase(final Context context) {
DataRequest.requestUploadCase(new RequestListener() {
@Override
public void requestFinish(Object result) {
((BaseActivity) context).setResult(Activity.RESULT_OK);
((BaseActivity) context).finish();
((BaseActivity) context).closeLoading();
}

@Override
public void requestNext() {
((BaseActivity) context).setResult(Activity.RESULT_OK);
((BaseActivity) context).finish();
((BaseActivity) context).closeLoading();
}
});
}

//上传工作日志
public void uploadWorkLog(final Context context){
DataRequest.updateWorkLog(new RequestListener() {

@Override
public void requestNext() {
((BaseActivity) context).setResult(Activity.RESULT_OK);
((BaseActivity) context).finish();
((BaseActivity) context).closeLoading();
}

@Override
public void requestFinish(Object result) {
((BaseActivity) context).setResult(Activity.RESULT_OK);
((BaseActivity) context).finish();
((BaseActivity) context).closeLoading();
}
});
}

}

1.自定义的一个类，然后在里面写了一个自定的方法

2.单例的编写方法，需要看看
