我在CollapsingToolBar里面使用CoordinatorLayout,我NestScrollView包含一些EditText作为子视图.我面临的是当edittext聚焦并且keybaoard出现时我的完整视图没有向上滚动.

下面是代码和图像作为该布局的输出.

我想在本地连接mysql数据库与android模拟器.我使用http GET和POST方法通过app引擎访问Google Cloud SQL中的数据,但我想使用phpmyadmin将其与本地连接.

当我使用以下代码时,它显示Toast连接失败

        String result = "";
        //the year data to send
        ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
        nameValuePairs.add(new BasicNameValuePair("name","Hammad"));

        //http post
        try{
                HttpClient httpclient = new DefaultHttpClient();
                HttpPost httppost = new HttpPost("http://localhost/myApp/read_data.php");
                httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
                HttpResponse response = httpclient.execute(httppost); 
                HttpEntity entity = response.getEntity();
                is = entity.getContent();

                Log.e("log_tag", "connection success ");
                Toast.makeText(getApplicationContext(), "pass", Toast.LENGTH_SHORT).show();
        }catch(Exception e){
                Log.e("log_tag", "Error in http connection "+e.toString());
                Toast.makeText(getApplicationContext(), "Connection fail", Toast.LENGTH_SHORT).show();

        }
        //convert response to string
        try{
                BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
