php - 将输入数据从android发送到php

Question

这些代码在按下按钮后执行。我正在尝试将字符串数据发送到我服务器中的 php 文件。但是在我按下按钮后应用程序停止了。我能知道这里有什么问题吗？非常感谢任何帮助:D

        HttpClient client = new DefaultHttpClient();
        HttpPost hpost = new HttpPost("http://myservername.com/postTest.php");
        status = mStatus.getText().toString();
        event = mEvent.getText().toString();
        time = mTime.getText().toString();
        try{
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
            nameValuePairs.add(new BasicNameValuePair("status", status));
            nameValuePairs.add(new BasicNameValuePair("event", event));
            nameValuePairs.add(new BasicNameValuePair("time", time));
            hpost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
            client.execute(hpost);
            mStatus.setText("");
            mEvent.setText("");
            mTime.setText("");
        }catch (UnsupportedEncodingException e){
            Toast.makeText(this, "Unsupported Encoding Exception " + e.getMessage(), Toast.LENGTH_LONG).show();
        }catch (ClientProtocolException e){
            Toast.makeText(this, "Client Protocol Exception " + e.getMessage(), Toast.LENGTH_LONG).show();
        }catch (IOException e){
            Toast.makeText(this, "IO Exception "+e.getMessage(), Toast.LENGTH_LONG).show();
        }

将你的代码放到线程中

new Thread(new Runnable() {

    @Override
    public void run() {
        // TODO Auto-generated method stub
        // do something
    }
}).start();

并检查你的 AndroidManifest.xml 权限

<uses-permission android:name="android.permission.INTERNET"/>
