使用適配器將數據從第一個活動傳遞到片段

Question

我能夠將數據從第一個活動傳遞到第二個活動，但我決定在我的第二個活動中添加片段，現在它不起作用。 我對 Android Studio 完全陌生，我試圖尋找解決方案，但找不到。

我在 logcat 中遇到錯誤

    java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.galila/com.example.galila.MainDetails}: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.TextView.setText(java.lang.CharSequence)' on a null object reference

Answer 1

您需要使用 Bundle 將數據從活動傳遞到片段

這是一個示例代碼：

創建捆綁包 object 並像這樣分配值

 Bundle bundle = new Bundle();
 bundle.putString("image", mainHelperClass.getImage());
 bundle.putString("gallery1", mainHelperClass.getGallery1());
 bundle.putString("gallery2", mainHelperClass.getGallery2());
 bundle.putString("gallery3", mainHelperClass.getGallery3());
 bundle.putString("gallery4", mainHelperClass.getGallery4());
 bundle.putString("place name", mainHelperClass.getPlaceName());
 bundle.putString("location", mainHelperClass.getLocation());
 bundle.putString("description", mainHelperClass.getDescription());
 bundle.putString("distance", mainHelperClass.getDistance());
 bundle.putString("km", mainHelperClass.getKm());
 bundle.putString("todo1", mainHelperClass.getTodo1());
 bundle.putString("todo2", mainHelperClass.getTodo2());
 bundle.putString("todo3", mainHelperClass.getTodo3());
 bundle.putString("todo4", mainHelperClass.getTodo4());
 bundle.putString("todo5", mainHelperClass.getTodo5());

調用片段並從適配器 class 傳遞 arguments

    YourFragment fragment = new YourFragment();
    fragment.setArguments(bundle);
    FragmentManager fragmentManager = ((FragmentActivity) context).getSupportFragmentManager();
    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
    fragmentTransaction.replace(R.id.frame_id, fragment);
    fragmentTransaction.addToBackStack(null);
    fragmentTransaction.commit();

Answer 2

您可以通過Bundle將數據活動傳遞給片段

Bundle bundle = new Bundle();
bundle.putString("edttext", "From Activity");
// set Fragmentclass Arguments
Fragmentclass fragobj = new Fragmentclass();
fragobj.setArguments(bundle);

在片段中獲取這些數據

String strtext = getArguments().getString("edttext");    
return inflater.inflate(R.layout.fragment, container, false);
