以下是Android Studio代码，同时我添加了下面的html代码，使用JavaScript在cookie中记住用户名和密码。它只在某些Android设备上有效。我不知道为什么。我希望它能在所有Android设备上运行。 希望有一个简单的方法实现。请帮忙看看。 我希望用户只需在第一次输入用户名/密码，下次访问时就可以自动填写。
public class MainActivity extends AppCompatActivity {
private Toolbar toolbar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.app_bar);
setSupportActionBar(toolbar);
getSupportActionBar().setTitle("Go To Our Facebook Page");
WebView myWebView = (WebView) findViewById(R.id.webview);
myWebView.setWebViewClient(new WebViewClient());
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
myWebView.loadUrl("http://www.hksalonjob.comslogin.php");
}
在这里使用HTML代码，使用JavaScript来记住用户名和密码。
