我对使用Android Studio进行开发相当陌生,所以我很可能会发现这个完全错误...
我的PHP脚本运行良好:
<?php
$con=mysqli_connect("xxx.178.143.xxx","roomapp","xxx","roomapp");
date_default_timezone_set('America/New_York');
$testschedulesql = "SELECT * from raRmSchedule WHERE '" . date('Y-m-d G:i:s') . "' > rsintime and '" . date('Y-m-d G:i:s') . "' < rsouttime";
$testscheduleqry = mysqli_query($con, $testschedulesql);
$testschedule = mysqli_num_rows($testscheduleqry);
$testscheduletext = mysqli_fetch_array($testscheduleqry);
if($testschedule > 0){
echo'Busy';
}
else{
echo'Free';
}
?>
我希望这能在我的Android应用中运行。到目前为止,我的java文件看起来像这样:
package com.sinteksolutions.roomapp2;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.TextView;
import android.widget.Toast;
import org.apache.http.HttpRequest;
import org.apache.http.HttpResponse;
import org.apache.http.client.HttpClient;
import org.apache.http.client.methods.HttpGet;
import org.apache.http.impl.client.DefaultHttpClient;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.URI;
public class MyActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my);
Thread thread = new Thread(new Runnable() {
@Override
public void run() {
try {
Thread.sleep(1000);
runOnUiThread(new Runnable() {
public void run() {
BufferedReader in = null;
try {
HttpClient client = new DefaultHttpClient();
HttpGet request = new HttpGet();
URI website = new URI("http://sinteksolutions.com/rmscheduler/timetest.php");
request.setURI(website);
HttpResponse response = client.execute(request);
in = new BufferedReader(new InputStreamReader(
response.getEntity().getContent()
));
String line = in.readLine();
TextView rmstatus = (TextView) findViewById(R.id.therm);
rmstatus.setText(line);
} catch (Exception e) {
//do something here
}
}
});
} catch (InterruptedException e) {
}
}
});
thread.start();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.my, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
这是我的XML:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
tools:context=".MyActivity">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/therm"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true" />
</RelativeLayout>
我有互联网权限设置。
有时这在模拟器中工作正常并显示文本。有时它什么也没显示。但该应用程序始终运行。
我做错了什么?或者有更好的方法吗?谢谢!
