我的主要活动有一个导航视图,并希望在导航视图上的用户更新信息,恢复活动:
1- if user is log in show the charging account menu item and sign
out menu item
2- if user is sign out , show sign in menu item and hide charging
account
private void handleUserLogin(){
NavigationView navigationView = (NavigationView) findViewById(R.id.navigation_main);
TextViewWithCustomFont fullNameTextView=(TextViewWithCustomFont)findViewById(R.id.userName_navigation);
TextViewWithCustomFont emailTextView=(TextViewWithCustomFont)findViewById(R.id.user_email_navigation);
final TextViewWithCustomFont balanceTextview=(TextViewWithCustomFont)findViewById(R.id.user_balance_navigation);
ImageView avatarImageView=(ImageView)findViewById(R.id.navigation_profile_image);
MenuItem chargeHesabMenuItem=navigationView.getMenu().findItem(R.id.navigation_charge);
applyFontToMenuItem(chargeHesabMenuItem);
if (isLogined()) {
try {
MenuItem menuItem=navigationView.getMenu().findItem(R.id.navigation_sign_out);
menuItem.setTitle("خروج از حساب کاربری");//set title to sign out
applyFontToMenuItem(menuItem);
menuItem.setOnMenuItemClickListener(new MenuItem.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
new SignoutFragment().show(getSupportFragmentManager(), "");
return true;
}
});
chargeHesabMenuItem.setOnMenuItemClickListener(new MenuItem.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
//show dialog of charging account because user stock is not enough
ChargeDialog dialog = new ChargeDialog();
dialog.show(getSupportFragmentManager(), "");
dialog.setOnDismissListener(new DialogInterface.OnDismissListener() {
@Override
public void onDismiss(DialogInterface dialog) {
getUserBalance(getUserId());
}
});
return false;
}
});
//fill user data
SharedPreferences sharedPreferences=getSharedPreferences(ReservationActivity.SHP_NAME, MODE_PRIVATE);
String firstName=sharedPreferences.getString(ReservationActivity.JSON_KEY_FIRST_NAME, "");
String lastName=sharedPreferences.getString(ReservationActivity.JSON_KEY_LAST_NAME,"");
fullNameTextView.setText(firstName+" "+lastName);
String email=sharedPreferences.getString(ReservationActivity.JSON_KEY_EMAIL,"");
emailTextView.setText(email);
String avatarUrl=sharedPreferences.getString(ReservationActivity.JSON_KEY_AVATAR,"");
Picasso.with(this).load(avatarUrl).placeholder(ResourcesCompat.getDrawable(getResources(),R.drawable.profile_image,null)).error(ResourcesCompat.getDrawable(getResources(),R.drawable.profile_image,null)).into(avatarImageView);
//get balance of user
int userId=sharedPreferences.getInt(ReservationActivity.JSON_KEY_USER_ID, 0);
onBalanceGetted=new OnBalanceGetted() {
@Override
public void onBalanceGetted(long balance) {
balanceTextview.setText(ConvertEnglishDigitsToFarsi.getInstance().convert(balance) + " ریال");
}
};
getUserBalance(userId);
//set visibilities
balanceTextview.setVisibility(View.VISIBLE);
emailTextView.setVisibility(View.VISIBLE);
} catch (Exception e) {
e.printStackTrace();
}
}else {
MenuItem menuItem= navigationView.getMenu().findItem(R.id.navigation_sign_out);
chargeHesabMenuItem.setVisible(false);
menuItem.setTitle("ورود به حساب کاربری");//set title to sign in
applyFontToMenuItem(menuItem);
menuItem.setOnMenuItemClickListener(new MenuItem.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
startActivity(new Intent(ConsultantsActivity.this, LoginActivity.class));
return true;
}
});
//fill user data
fullNameTextView.setText("وارد حساب کاربری خود شوید");
avatarImageView.setImageDrawable(ResourcesCompat.getDrawable(getResources(),R.drawable.profile_image,null));
//set visibilities
emailTextView.setVisibility(View.GONE);
balanceTextview.setVisibility(View.GONE);
}
navigationView.buildLayer();
navigationView.forceLayout();
navigationView.invalidate();
navigationView.requestLayout();
}
但是当对导航视图进行此更改时,它不起作用,并且在用户单击其中一个菜单项之前不会刷新!
这是什么原因!!!如何刷新导航视图菜单项???
