在單個webview中打開多個鏈接

Question

我正在創建一個具有包含多個網站鏈接的導航抽屜的項目。我想在單個webview中顯示所有的網站鏈接，以便在應用程序中打開它們。我嘗試了所有發佈和可能的解決方案，但沒有任何工作。請任何人都可以幫助我.. !!

您可以創建自己的網絡視圖活動，並在選擇導航項時像下面那樣開始活動。

Intent startWebViewIntent=new Intent(this,SurahWebviewActivity.class); 
    startWebViewIntent.putExtra("PrayerTime",1); 
    startActivity(startWebViewIntent); 

但是在您的代碼中，您可以創建一個方法來加載帶有鏈接的Web視圖，並在選擇導航項時調用該方法。它可能像下面這樣。

public boolean onNavigationItemSelected(MenuItem item) 
    { 
     // Handle navigation view item clicks here. 

     int id = item.getItemId(); 

     if (id == R.id.classmaster) 
     { 
      URI uri=Uri.parse("http://app.schoolbios.com/main#/class_master")); 
      populateWebView(uri); 
     } 
} 

private void populateWebView(URI uri){ 
    thisWebView.loadUrl(uri); 
}
