cc_美團項目之Util使用

1. Toast工具

   
   

   
   

public class MyToast {

public static void makeText(Context context, CharSequence text){

Toast.makeText(context, text, Toast.LENGTH_SHORT).show();

}

}

1.1 Toast工具 

final User user = new User(username, password,"138604167");

user.signUp(getActivity(), new SaveListener() {

public void onSuccess() {

MyToast.makeText(getActivity(),"注冊成功:" + user.getUsername() + "-" + user.getObjectId()

+ "-" + user.getCreatedAt() + "-"

+ user.getSessionToken() + ",是否驗證："

+ user.getEmailVerified());

2. 判斷登錄狀態工具

private static LoginStatus mInstance = new LoginStatus();

private boolean hasLogin;

private LoginStatus(){}

public static LoginStatus getInstance(){

return mInstance;

}

public boolean hasLogin() {

return hasLogin;

}

public void setHasLogin(boolean hasLogin) {

this.hasLogin = hasLogin;

}

}

2.1 注冊成功后設置登錄狀態為true，再跳轉

myUser = BmobUser.getCurrentUser(getActivity(), com.chencheng.model.User.class);

Log.e("life","本地用戶信息:objectId = " + myUser.getObjectId() + ",name = " + myUser.getUsername()

);

LoginStatus.getInstance().setHasLogin(true);

Intent intent = new Intent(getActivity(),

MainActivity.class);

intent.putExtra("user", myUser);

intent.putExtra("flag", "hasLogin");

startActivity(intent);

2.2 MainActivity中接受Intent值，如果是登陸成功，直接條狀到MineFragment

Intent intent=getIntent();

       flag = intent.getStringExtra("flag");

       if(flag!=null){

       Log.e("MainIntent", flag);

       if(flag.equals("hasLogin")){

      mTabHost.setCurrentTab(2);

       }

       }

2.3 MineFragment里面根據登錄狀態設置不同顯示界面

if (LoginStatus.getInstance().hasLogin()){

com.chencheng.model.User myUser = BmobUser.getCurrentUser(getActivity(), com.chencheng.model.User.class);

TextView username=(TextView)mLayout.findViewById(R.id.username);

username.setText(myUser.getUsername());

mLayout.findViewById(R.id.has_not_login_container).setVisibility(View.GONE);

mLayout.findViewById(R.id.logined_container).setVisibility(View.VISIBLE);

}else{

mLayout.findViewById(R.id.has_not_login_container).setVisibility(View.VISIBLE);

mLayout.findViewById(R.id.logined_container).setVisibility(View.GONE);

}

3.跳轉工具（基于判斷登錄狀態）

public class UnLoginUtils {

public static void startActivity(Context context, Class class1){

if (LoginStatus.getInstance().hasLogin()){

context.startActivity(new Intent(context, class1));

}else{

context.startActivity(new Intent(context, LoginActivity.class));

}

}

}
