我在MainAvtivity中有以下代码:

private DBOperations DataDBoperation;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        DataDBoperation = new DBOperations(this);
        DataDBoperation.open();

        List values = DataDBoperation.getAllUserSIMs();

                android.R.layout.simple_list_item_1, values);
        setListAdapter(adapter);



    }
    public void addSim(View view) {

        ArrayAdapter adapter = (ArrayAdapter) getListAdapter();

        EditText text = (EditText) findViewById(R.id.editText1);
        SIMsClass stud = DataDBoperation.addSIMs(text.getText().toString());

        adapter.add(stud);

    }

    public void deleteSim(View view) {

        ArrayAdapter adapter = (ArrayAdapter) getListAdapter();
        SIMsClass sim = null;

        if (getListAdapter().getCount() > …

我正在开发一个Android应用程序,它要求我扫描所有可用的公共wifi网络并连接到具有最高信号强度的网络.这可以实现如此如何？

现在我的应用程序只需打开wifi并连接到已保存的网络.
