RyMiniFramework(4)-引导界面

由于引导界面处于欢迎界面和主界面之间， 所以，最后还是把引导界面的实现放在了前面写好的RmfSplash类中。

RMF中引导界面是用gallery来实现，当处于最后一张图片时，向右滑动即可进入主界面。

 

1、cn.rydiy.rmf.common.RmfGuide.java

package cn.rydiy.rmf.common;import java.util.ArrayList;import android.app.Activity;import android.content.Context;import android.content.res.Resources;import android.graphics.Bitmap;import android.graphics.BitmapFactory;import android.util.AttributeSet;import android.view.KeyEvent;import android.view.MotionEvent;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.Gallery;import android.widget.ImageView;import android.widget.LinearLayout;import android.widget.LinearLayout.LayoutParams;/** * Guide Display Class *  * @author Rydiy * @version 1.0.0 * @Date 2012-07-30 */public class RmfGuide {private ArrayList<Integer> mImgList; // guide images' idprivate RmfGallery mGallery; // guide galleryprivate Resources mRes; // Resourcesprivate Activity mAct; // MainActivityprivate int mCurPosition; //gallery current page/** * Constructor *  * @param imgs *            : A array of guide-images' id * @param act *            : your object's main activity's instance * @param res *            : A Resources instance for your application's package */public RmfGuide(ArrayList<Integer> imgs, Activity act, Resources res) {mImgList = imgs;mAct = act;mRes = res;mCurPosition = 0;}/** * Show guide */public void show() {//get layoutLinearLayout layout = (LinearLayout) mAct.findViewById(mRes.getIdentifier("rmf_id_splash_ly", "id",mAct.getPackageName()));mGallery = new RmfGallery(mAct);ImageAdapter imgAdapter = new ImageAdapter(mAct);mGallery.setAdapter(imgAdapter);//add gallery to layoutlayout.removeAllViews();layout.addView(mGallery, new LayoutParams(LinearLayout.LayoutParams.FILL_PARENT,LinearLayout.LayoutParams.FILL_PARENT));}/** * Custom gallery * @author Rydiy *  */private class RmfGallery extends Gallery {public RmfGallery(Context context) {super(context);}public RmfGallery(Context context, AttributeSet attrs) {super(context, attrs);}private boolean isScrollingLeft(MotionEvent e1, MotionEvent e2) {return e2.getX() > e1.getX();}@Overridepublic boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,float velocityY) {int kEvent;if (isScrollingLeft(e1, e2)) {// Check if scrolling leftkEvent = KeyEvent.KEYCODE_DPAD_LEFT;} else {// Otherwise scrolling rightkEvent = KeyEvent.KEYCODE_DPAD_RIGHT;//if it is the last page, load main layoutif (mCurPosition == getSelectedItemPosition()&& mCurPosition == getCount() - 1) {mAct.setContentView(mRes.getIdentifier("main", "layout",mAct.getPackageName()));} else {mCurPosition = getSelectedItemPosition();}}onKeyDown(kEvent, null);return true;}}/** * ImageAdapter for gallery * @author Rydiy *  */private class ImageAdapter extends BaseAdapter {private Context mContext = null;public ImageAdapter(Context c) {this.mContext = c;}public int getCount() {return mImgList.size();}public Object getItem(int position) {return position;}public long getItemId(int position) {return position;}public View getView(int position, View convertView, ViewGroup parent) {ImageView mImageView = new ImageView(mContext);int id = mImgList.get(position);Bitmap bmp = BitmapFactory.decodeResource(mRes, id);mImageView.setImageBitmap(bmp);mImageView.setScaleType(ImageView.ScaleType.FIT_XY);mImageView.setLayoutParams(new android.widget.Gallery.LayoutParams(android.widget.Gallery.LayoutParams.FILL_PARENT,android.widget.Gallery.LayoutParams.FILL_PARENT));return mImageView;}}}

 

2、cn.rydiy.rmf.common.RmfSplash.java修改如下：

package cn.rydiy.rmf.common;import java.util.ArrayList;import android.app.Activity;import android.content.SharedPreferences;import android.content.res.Resources;import android.graphics.Bitmap;import android.graphics.BitmapFactory;import android.os.Handler;import android.os.Message;import android.util.Log;import android.view.Window;import android.view.WindowManager;import android.widget.ImageView;/** * Splash Display Class. It will display splash with full screen and then quit * full screen. *  * @author Rydiy * @version 1.0.0 * @Date 2012-07-29 */public class RmfSplash {private Activity mActivity; // MainActivityprivate int mDelayTime; // delay timeprivate int mMainLayoutResID; // /the resource id of the main layoutprivate int mSplashLayoutResID; // /the resource id of the splash layoutprivate int mSplashImgViewResID; // /the resource id of the splash imageviewprivate int mSplashImgResID; // the resource id of the splash image dataprivate ArrayList<Integer> mGuideImgs; // imags for guideprivate Handler mHandler; // message handlerprivate Resources mRes; // the resources object containing the image data/** * Constructor *  * @param mainActivity *            :Application's main acitivity */public RmfSplash(Activity mainActivity) {this.mActivity = mainActivity;}/** * Set splash settings * @param res *            :The resources object containing the image data * @param splashImgResID *            :The resource id of the image data */public void setSplash(Resources res, int splashImgResID) {this.mRes = res;String packageName = mActivity.getPackageName();// get R.layout.mainmMainLayoutResID = mRes.getIdentifier("main", "layout", packageName);setSplash(res, splashImgResID, mMainLayoutResID);}/** * Set splash settings * @param res *            :The resources object containing the image data * @param splashImgResID *            :The resource id of the image data * @param mainLayoutResID *            :The resource id of the application's main layout */public void setSplash(Resources res, int splashImgResID, int mainLayoutResID) {this.mRes = res;this.mSplashImgResID = splashImgResID;this.mMainLayoutResID = mainLayoutResID;String packageName = mActivity.getPackageName();// get R.layout.rmf_ly_splashmSplashLayoutResID = mRes.getIdentifier("rmf_ly_splash", "layout",packageName);// get R.id.rmf_id_splash_imgmSplashImgViewResID = mRes.getIdentifier("rmf_id_splash_img", "id",packageName);// create HandlermHandler = new Handler() {@Overridepublic void handleMessage(Message msg) {if (1 == msg.arg1) {Log.d("RMF", "RmfSplash recive handler");// quit full screenquiteFullScreen();// show guideViewif (null == mGuideImgs) {mActivity.setContentView(mMainLayoutResID);} else {showGuide();}}}};}/** * Show splash and guide * @param delayTime *            : Time for splash display */public void show(int delayTime) {Log.d("RMF", "RmfSplash show()");this.mDelayTime = delayTime;// no titlemActivity.requestWindowFeature(Window.FEATURE_NO_TITLE);// full screenmActivity.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);// set splash layoutmActivity.setContentView(mSplashLayoutResID);// load bitmapBitmap bmp = BitmapFactory.decodeResource(mActivity.getResources(),mSplashImgResID);ImageView img = (ImageView) mActivity.findViewById(mSplashImgViewResID);img.setImageBitmap(bmp);// delay timenew Thread() {public void run() {Message msg = Message.obtain(mHandler);msg.arg1 = 1;mHandler.sendMessageDelayed(msg, mDelayTime);};}.start();}/** * Set images for guide * @param guideImgs *            :Images for guide */public void setGuide(ArrayList<Integer> guideImgs) {mGuideImgs = guideImgs;}/** * Quite full screen */private void quiteFullScreen() {final WindowManager.LayoutParams attrs = mActivity.getWindow().getAttributes();attrs.flags &= (~WindowManager.LayoutParams.FLAG_FULLSCREEN);mActivity.getWindow().setAttributes(attrs);mActivity.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);}/** * Show guide view */private void showGuide() {SharedPreferences appInfo = mActivity.getPreferences(0);Boolean first = appInfo.getBoolean("first", true);if (first) {// first time, show guideappInfo.edit().putBoolean("first", false).commit();RmfGuide rmfGuide = new RmfGuide(mGuideImgs, mActivity, mRes);rmfGuide.show();} else {// Not the first time, set main layoutmActivity.setContentView(mMainLayoutResID);}}}

3、调用

 

       Log.d("RMF", "OnCreate");        //new RmfSplash        RmfSplash rSplash = new RmfSplash(this);                //imgs for guide        ArrayList<Integer> imgs = new ArrayList<Integer>();        imgs.add(R.drawable.feature_guide_0);        imgs.add(R.drawable.feature_guide_1);        imgs.add(R.drawable.feature_guide_2);        imgs.add(R.drawable.feature_guide_3);        //set imgs to RmfSplash        rSplash.setGuide(imgs);        //set splash settings        //rSplash.setSplash(getResources(), R.drawable.rmf_img_splash);              rSplash.setSplash(getResources(), R.drawable.rmf_img_splash, R.layout.rmf_ly_tabmain);                //show splash and guide        rSplash.show(3000);

 

现在的版本可以指定加载的主layout，  默认为main.layout
