项目中加入xutils
compile 'org.xutils:xutils:3.3.42'使用前加入权限:
<uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <EditText android:id="@+id/et_main_uname" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="admin" /> <EditText android:id="@+id/et_main_upass" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="123456" /> <Button android:id="@+id/btn_main_login" android:layout_width="match_parent" android:layout_height="wrap_content" android:text="登录" />一个简单登录的dom，这里就没有连接数据库，使用前初始化xutils
@Override public void onCreate() { super.onCreate(); //初始化XUtils x.Ext.init(this); }在mainActivity中写调用:
@Override PRotected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); x.view().inject(this); } @Event(value = R.id.btn_main_login,type = View.OnLongClickListener.class) private boolean login(View view){ //获取文本框的值 String name=et_main_uname.getText().toString(); String pass=et_main_upass.getText().toString(); //发送请求RequestParams params=new RequestParams("http://192.168.43.196:8090/loginResult.xhtml"); params.addParameter("uname",name); params.addParameter("upass",pass); x.http().post(params, new Callback.CommonCallback<String>() { @Override public void onSuccess(String result) { Toast.makeText(MainActivity.this, result, Toast.LENGTH_SHORT).show(); } @Override public void onError(Throwable ex, boolean isOnCallback) { } @Override public void onCancelled(CancelledException cex) { } @Override public void onFinished() { } }); return true; }}新闻热点
