1.访客预约的设计完成

思路：

（1）界面依据需求设计 VisitorActivity

（2）选择时间功能的时间

（3）下一步：二维码生成（包含信息：卡ID，开始时间，结束时间）

【具体解决】

（1）界面设计

...常用 <LinearLayout> <RelativeLayout>来共同完成

固定边框或图标可用xml文件布置，在空间中用background调用

drawable/corners_bg文件如下

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="@color/white" />
<stroke android:color="@color/frame_color" android:width="2px"/> //宽度大小
<corners android:topLeftRadius="5dp"
android:topRightRadius="5dp"
android:bottomRightRadius="5dp"
android:bottomLeftRadius="5dp"/>
</shape>

Button风格也可由资源文件配置

style="@style/ButtonStyle1"文件如下：

<item name="android:background">@drawable/selector_bg_btn_1</item>
<item name="android:textColor">@android:color/white</item>
<item name="android:textSize">@dimen/button1_textSize</item>
<item name="android:gravity">center</item>
<item name="android:layout_width">@dimen/button1_defaultWidth</item>
<item name="android:layout_height">@dimen/button1_defaultHeight</item>
</style>

drawable/selector_bg_btn_1文件如下：
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/shape_bg_btn_1_pressed" android:state_pressed="true"/>
<item android:drawable="@drawable/shape_bg_btn_1_disabled" android:state_enabled="false"/>
<item android:drawable="@drawable/shape_bg_btn_1_default"/>
</selector>

drawable/shape_bg_btn_1_pressed" android:state_pressed="true文件如下：
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >

<solid android:color="@color/button1_bg_pressed" />


<corners android:radius="@dimen/button1_radius" />

<padding
android:bottom="10dp"
android:left="10dp"
android:right="10dp"
android:top="10dp" />
</shape>

【标题边框】

设置个性标题边框，无需将原有的边框隐藏，就可覆盖原有的边框

public class VisitorActivity extends AppBaseActivity{

}

VisitorActivity 继承一个原有的类AppBaseActivity

原有类中提供了固定标题栏

在AndroidManifest.xml 文件中添加 android:label="@string/VisitorOrder" 新标题即可完成一个自定义的标题边框

public abstract class AppBaseActivity extends BaseActivity {
protected LinearLayout llActionbarRight;
protected TextView tvTitle;
protected Button btnBack;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

ActionBar actionBar = getActionBar();
if (actionBar != null) {
actionBar.setDisplayShowCustomEnabled(true);
// actionBar.setDisplayShowTitleEnabled(false);
// actionBar.setDisplayShowHomeEnabled(false);
actionBar.setCustomView(R.layout.ui_actionbar);
actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);

btnBack = (Button) actionBar.getCustomView().findViewById(R.id.actionbar_back_button);
tvTitle = (TextView) actionBar.getCustomView().findViewById(R.id.actionbar_title_textview);
llActionbarRight = (LinearLayout) actionBar.getCustomView().findViewById(R.id.ll_actionbar_right);

tvTitle.setText(getTitle());

btnBack.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {
onBackPressed();
}
});
}
}

@Override
public void setTitle(int titleId) {
super.setTitle(titleId);
tvTitle.setText(titleId);
}

@Override
public void setTitle(CharSequence title) {
super.setTitle(title);
tvTitle.setText(title);
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item.getItemId() == android.R.id.home) {
finish();
return true;
}
return super.onOptionsItemSelected(item);
}

protected boolean onPreInvoke() {
if (!NetworkUtils.isNetworkConnected()) {
Toast.makeText(AppBaseActivity.this, R.string.noNetworkConnect, Toast.LENGTH_SHORT).show();
return false;
} else {
return true;
}
}

protected boolean needCallback;

protected ProgressDialog mProgressDialog;

protected abstract class AbstractRequestCallback implements RequestCallback {

@Override
public abstract void onSuccess(String content);

@Override
public void onFail(int code) {
if (mProgressDialog != null && mProgressDialog.isShowing()) {
mProgressDialog.dismiss();
mProgressDialog = null;
}

String errMsg = "";
switch (code) {
case HttpRequest.EXCEPTION_CODE_NOT_FROM_SERVER:
errMsg = "连接服务器失败";
break;

default:
errMsg = "获取数据失败. error code " + code;
break;
}

new AlertDialog.Builder(AppBaseActivity.this)
.setTitle(R.string.tip)
.setMessage(errMsg)
.setPositiveButton(R.string.confirm, null)
.show();
}

@Override
public void onCookieExpired() {
if (mProgressDialog != null && mProgressDialog.isShowing()) {
mProgressDialog.dismiss();
mProgressDialog = null;
}

new AlertDialog.Builder(AppBaseActivity.this)
.setTitle(R.string.tip)
.setMessage("Cookie过期，请重新登录")
.setPositiveButton(R.string.confirm,
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
try {
Class clazz = Class.forName("com.leelen.account.activity.LoginActivity");
if (clazz != null) {
Intent intent = new Intent(AppBaseActivity.this, clazz);
intent.putExtra(LeelenConst.NEED_CALLBACK, true);
startActivity(intent);
}
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
})
.show();
}
}
}

/*
*BaseActivity
*/

public abstract class BaseActivity extends Activity {
protected Context mContext;
protected Resources mResources;
/**
* 请求列表管理器
*/
protected RequestManager requestManager = null;

@Override
protected void onCreate(Bundle savedInstanceState) {
mContext = this;
mResources = mContext.getResources();
requestManager = new RequestManager();

super.onCreate(savedInstanceState);

initVariables();
initViews(savedInstanceState);
loadData();
}

protected abstract void initVariables();
protected abstract void initViews(Bundle savedInstanceState);
protected abstract void loadData();

@Override
protected void onDestroy() {
/**
* 在activity销毁的时候同时设置停止请求，停止线程请求回调
*/
if (requestManager != null) {
requestManager.cancelRequest();
}
super.onDestroy();
}

@Override
protected void onPause() {
/**
* 在activity停止的时候同时设置停止请求，停止线程请求回调
*/
if (requestManager != null) {
requestManager.cancelRequest();
}
super.onPause();
}

public RequestManager getRequestManager() {
return requestManager;
}
}
