我是android编程的新手。我在互联网上搜索但我找不到任何解决方案，也许为此我的英语不好。反正。当用户单击网络链接时，我想向打开 wifi 的用户显示警报对话框，然后用户单击 OK 按钮，显示 wifi 设置。

这是我的带有链接的 TextView：

  <TextView
    android:id="@+id/sitename"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/site2"
    android:background="@color/white"
    android:layout_below="@id/address"
    android:layout_toLeftOf="@id/site"
    android:paddingTop="3dp"
    android:paddingRight="5dp"
    android:autoLink="web"/>

我用strings.xml 设置web 文本。

对不起，如果我的问题被重复，对不起我糟糕的英语。干杯。

编辑：Contact.java：

public class Contact extends Fragment {

public String fonts="Tahoma.TTF";
Typeface face;

TextView siteName;

@Override 
public View onCreateView(LayoutInflater inflater,ViewGroup container, Bundle savedInstanceState){
    View view=inflater.inflate(R.layout.contact, container, false);
            siteName=(TextView)view.findViewById(R.id.sitename);
    siteName.setOnClickListener(onClickListener);

    return view;
}

private OnClickListener onClickListener=new OnClickListener(){

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        switch(v.getId()){
        case R.id.sitename:
            AlertDialog.Builder alertDialog=new AlertDialog.Builder(getActivity());
            alertDialog.setTitle("Turn on WI-Fi..");
            alertDialog.setMessage("Do you want to go to wifi settings?");
            alertDialog.setNegativeButton("Cancle", new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    // TODO Auto-generated method stub
                    dialog.cancel();
                }
            });
            alertDialog.setPositiveButton("OK", new DialogInterface.OnClickListener() {

                @Override
                public void onClick(DialogInterface dialog, int which) {
                    // TODO Auto-generated method stub
                    startActivity(new Intent(WifiManager.ACTION_PICK_WIFI_NETWORK));
                }
            });

            alertDialog.show();

            break;
        }
    }

};
 }

点击按钮试试这个：

AlertDialog.Builder alertDialog = new AlertDialog.Builder(
                this);

        // Setting Dialog Title
        alertDialog.setTitle("Confirm...");

        // Setting Dialog Message
        alertDialog.setMessage("Do you want to go to wifi settings?");

        // Setting Icon to Dialog
        // alertDialog.setIcon(R.drawable.ic_launcher);

        // Setting Positive "Yes" Button
        alertDialog.setPositiveButton("yes",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {

                        // Activity transfer to wifi settings
                        startActivity(new Intent(Settings.ACTION_WIFI_SETTINGS));
                    }
                });

        // Setting Negative "NO" Button
        alertDialog.setNegativeButton("no",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        // Write your code here to invoke NO event

                        dialog.cancel();
                    }
                });

        // Showing Alert Message
        alertDialog.show();

尝试将以下内容添加到onClickofButton

context.startActivity(new Intent(WifiManager.ACTION_PICK_WIFI_NETWORK));

这会将用户直接重定向到 wifi 设置屏幕

希望这有效

这应该工作

startActivity(new Intent(WifiManager.ACTION_PICK_WIFI_NETWORK));
