UARTlogfragment.javaのAndroidManifest.xmlに宣言されているグローバル変数にアクセスしようとしていますが、getApplication()の使用にエラーがあり、「解決できません」です。 私はAndroidManifest.xmlとUARTlogfragment.javaをここに掲載しています。Android Studio：getApplication（）を解決できません
のAndroidManifest.xmlは次のとおりです。（私はグローバル変数にアクセスしようとしています）

UARTlogfragment.javaは次のとおりです。エラーです
public View onCreateView(final LayoutInflater inflater, final ViewGroup container, final Bundle savedInstanceState) {
final View view = inflater.inflate(R.layout.fragment_feature_uart_log, container, false);
mydb = new no.nordicsemi.android.nrftoolbox.myDbAdapter(getContext());
String s = ((ToolboxApplication) this.getApplication()).getSomeVariable();
Cursor rs = mydb.getData(1);
rs.moveToFirst();
String nam = rs.getString(rs.getColumnIndex(no.nordicsemi.android.nrftoolbox.myDbAdapter.CONTACTS_COLUMN_NAME));
String phon = rs.getString(rs.getColumnIndex(no.nordicsemi.android.nrftoolbox.myDbAdapter.CONTACTS_COLUMN_PHONE));
String emai = rs.getString(rs.getColumnIndex(no.nordicsemi.android.nrftoolbox.myDbAdapter.CONTACTS_COLUMN_EMAIL));
String cit = rs.getString(rs.getColumnIndex(no.nordicsemi.android.nrftoolbox.myDbAdapter.CONTACTS_COLUMN_CITY));
String gend = rs.getString(rs.getColumnIndex(no.nordicsemi.android.nrftoolbox.myDbAdapter.CONTACTS_COLUMN_GENDER));
String pas = rs.getString(rs.getColumnIndex(no.nordicsemi.android.nrftoolbox.myDbAdapter.CONTACTS_COLUMN_PASS));
String dobb = rs.getString(rs.getColumnIndex(no.nordicsemi.android.nrftoolbox.myDbAdapter.CONTACTS_COLUMN_DOB));
if (!rs.isClosed()) {
rs.close();
}
final EditText field = mField = view.findViewById(R.id.field);
mField.setText(nam+" "+emai+" "+phon+" "+gend+" "+cit);
field.setOnEditorActionListener((v, actionId, event) -> {
if (actionId == EditorInfo.IME_ACTION_SEND) {
onSendClicked();
return true;
}
return false;
});
final Button sendButton = mSendButton = view.findViewById(R.id.action_send);
sendButton.setOnClickListener(v -> onSendClicked());
return view;
}
何？それでなぜ解決できないのですかgetApplication() ??
String s = ((ToolboxApplication) getActivity().getApplication()).getSomeVariable();
'getActivity（）。getApplicationを（）'を使用する必要が代わりに
this.getApplication()の、あなたのコードでをsumupする
