Я хотел бы использовать нижнюю навигацию, чтобы отображать URL-адрес в основном веб-просмотре, который есть в приложении. WebView называется AdvancedWebView и загружается в MainActivity. У меня в BottomNavigation 3 предмета. Мне нужно убедиться, что при нажатии на «Панель управления» в BottomNavigation в нее загружается URL.
Нижняя навигация Java для «DashBoard»:
package com.eternal.andamans;
import androidx.annotation.NonNull;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.MenuItem;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import com.eternal.andamans.activity.MainActivity;
import com.google.android.material.bottomnavigation.BottomNavigationView;
public class DashBoard extends AppCompatActivity {
WebView wv;
String url = "https://www.eternalandamans.com/tsg-bella-bay-in-andaman";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_dash_board);
//My Code from Here
BottomNavigationView bottomNavigationView = findViewById(R.id.bottom_navigation);
// Setting Home Selected here
bottomNavigationView.setSelectedItemId(R.id.dashboard);
// ItemSelectListener
bottomNavigationView.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
@Override
public boolean onNavigationItemSelected(@NonNull MenuItem menuItem) {
switch (menuItem.getItemId()){
case R.id.dashboard:
return true;
case R.id.home:
startActivity(new Intent(getApplicationContext()
, MainActivity.class));
overridePendingTransition(0,0);
return true;
case R.id.about:
startActivity(new Intent(getApplicationContext()
, About.class));
overridePendingTransition(0,0);
return true;
}
return false;
}
});
wv = (WebView) findViewById(R.id.DashboardWebView);
wv.setWebViewClient(new WebViewClient());
wv.getSettings().setJavaScriptEnabled(true);
wv.loadUrl(url);
}
}
В настоящее время я добавил для этого новый WebView. Мне нужно показать URL-адрес в том же WebView, что и в основном действии Java Файл.
