android脚步---UI界面修改，增加按钮和监听

我的UU界面，其布局如下：

需要修改的部分：

意见反馈居中，还有增加backbutton

首先在mainactivity中找到我的UU的定义：dialogue

public void showAboutDialog() {
    	if(mAboutDialog == null) {
            LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View aboutView = inflater.inflate(R.layout.aboutuu_layout, null, false);
            Button backBnt = (Button)aboutView.findViewById(R.id.backbutton);
            backBnt.setOnClickListener(mViewClickListener);
            TextView versionTxt = (TextView)aboutView.findViewById(R.id.versiontext);
            RelativeLayout versionCheckLayout = (RelativeLayout)aboutView.findViewById(R.id.checkversion);
            versionCheckLayout.setOnClickListener(mViewClickListener);
            RelativeLayout frameCheckLayout = (RelativeLayout)aboutView.findViewById(R.id.checkframe);
            frameCheckLayout.setOnClickListener(mViewClickListener);
     //       RelativeLayout focusWbLayout = (RelativeLayout)aboutView.findViewById(R.id.focusweibo);
     //       focusWbLayout.setOnClickListener(mViewClickListener);
     //       RelativeLayout focusWxLayout = (RelativeLayout)aboutView.findViewById(R.id.focusweixin);
     //       focusWxLayout.setOnClickListener(mViewClickListener);
            RelativeLayout  marketScore = (RelativeLayout)aboutView.findViewById(R.id.toscore);
            marketScore.setOnClickListener(mViewClickListener);
            RelativeLayout contactsLayout = (RelativeLayout)aboutView.findViewById(R.id.contactus);
            contactsLayout.setOnClickListener(mViewClickListener);
            RelativeLayout fansLayout = (RelativeLayout)aboutView.findViewById(R.id.introtomyfriend);
            fansLayout.setOnClickListener(mViewClickListener);
           
            if(isNeedAd == true) {
            	RelativeLayout rl_ad= (RelativeLayout)aboutView.findViewById(R.id.rl_ad);
            	banner=new DiandeBanner(this,banner_AD_ID);
            	if(banner != null) {
            		// rl_ad=(RelativeLayout)findViewById(R.id.rl_ad);
            		rl_ad.addView(banner);
            		banner.show();
            	}
            }
            

 根据R.layout找到各个对应的xml文件

，意见反馈对应的是contactus.进入它的监听中，监听按键找到它的xml入口。

 OnClickListener mViewClickListener = new OnClickListener() {
		
		@Override
		public void onClick(View v) {
			switch(v.getId()) {
			case R.id.checkversion:
			    UpdateManager manager = new UpdateManager(CameraActivity.this);
			    if (manager.isNetworkConnected()) {
			        manager.checkUpdate();
			    } else {
			        manager.showNetworkDialog();
			    }
				break;
				
			case R.id.toscore:
			    Uri uri = Uri.parse("market://details?id="+getPackageName());
			    Intent intent = new Intent(Intent.ACTION_VIEW,uri);
			    intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
			    try {
			    	startActivity(intent);
			    }catch(ActivityNotFoundException e) {
			    	CustomToast.showToast(CameraActivity.this, R.string.toast_appmarket_not_installed, Toast.LENGTH_SHORT);
			    }
			    break;
			case R.id.checkframe:
			    if (mCurrentModule instanceof PhotoModule) {
			        PhotoUI ui = ((PhotoModule) mCurrentModule).getPhotoUIInstance();
			        if (ui != null) {
			            PhotoFrameUpdateManager photoFrameManager = 
			                    new PhotoFrameUpdateManager(CameraActivity.this, ui);
			            if (photoFrameManager.isNetworkConnected()) {
//			                photoFrameManager.checkUpdate();
			            	startActivityForResult(new Intent(CameraActivity.this, KuangDownloadActivity.class), REQ_CODE_DOWNLOAD);
			            } else {
			                photoFrameManager.showNetworkDialog();
			            }
			        }
			    }
			    break;
			case R.id.contact_weibo:
				followWB();
				break;
			case R.id.contact_weixin:
				showFollowWxDialog();
				break;
			case R.id.contactus:
				showContactsFunc();
				break;
			case R.id.contact_fans:
				showFansforumPage();
				break;
            case R.id.introtomyfriend:
            	Intent recIntent = new Intent(Intent.ACTION_SEND);
            	recIntent.setType("text/plain");
            	recIntent.putExtra(Intent.EXTRA_TEXT, CameraActivity
            			.this.getString(R.string.rec_app_msg)+Constants.UU_LINK_URI);
				startActivity(recIntent);
            	break;
			case R.id.backbutton:
				if(mAboutDialog != null) {
					mAboutDialog.dismiss();
					mAboutDialog = null;
				}
				break;
			case R.id.backbutton1:
				if(mFeedBackDialog != null) {
					mFeedBackDialog.dismiss();
					mFeedBackDialog = null;
				}
				break;
			}
		}
	};
	

 找到R.id.contact_weibo,点击进入xml文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:background="#ffffff" >
    
<RelativeLayout
        android:id="@+id/title"
        android:layout_height="@dimen/about_title_height"
        android:layout_width="match_parent"
        android:background="@color/aboutuu_title"
        >
    <TextView
        android:id="@+id/title_text"
        android:layout_width="match_parent"
        android:layout_height="@dimen/about_title_height"
        android:gravity="center"
        android:text="@string/contact_us"
        android:textColor="#ffffff"
        android:textSize="@dimen/about_title_text_size" 
        android:background="@color/aboutuu_title"
        android:paddingLeft="@dimen/about_title_btn_margin_left"/>

    <Button
        android:id="@+id/backbutton1"
        android:layout_width="@dimen/about_title_height"
        android:layout_height="@dimen/about_title_height"
        android:layout_centerVertical="true"
        android:layout_marginLeft="@dimen/about_title_btn_margin_left"
        android:background="@drawable/about_back" />
    </RelativeLayout>
    

 将其 android:gravity="center"变成居中，还有增加Button，因为增加Button后提示android:layout_centerVertical="true"应用于相对布局，所以将线性布局改成相对布局。布局文件修改iwanbi后在JAVA文件中增加监听：

if(mFeedBackDialog == null) {
    		LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View fbView = inflater.inflate(R.layout.feedback_layout, null, false); 
            Button backBn = (Button)fbView.findViewById(R.id.backbutton1);
            backBn.setOnClickListener(mViewClickListener);

 利用inflater引入布局文件，定义按钮，引用公共监听类，公共监听类中增加按钮backbutton1.
