android 引导图engine类封装

暂时做的是全局点击区域,如果要做那种热点点击区域也是可以的哈,给我一个填充器就能产生一个view,既然能产生一个view,那么也就能产生一个引导.....

附上我的原创封装代码:

GuidePageEngine.java<pre style="font-family: 宋体; font-size: 12pt; background-color: rgb(255, 255, 255);"><pre name="code" class="java">import android.app.Activity;
import android.util.Log;
import android.view.View;
import android.view.ViewGroup;
import android.view.ViewParent;
import android.widget.FrameLayout;
import android.widget.ImageView;

import com.meimi.youganjue.interf.INotify;

import java.util.ArrayList;

public class GuidePageEngine {


    private static final String TAG = "GuidePageEngine";
    private int nextResouceIndex =0;
    private ArrayList<Integer> lists;
    private Activity activity;
    int currentLayoutId;
    private INotify iNotify;
    private ImageView currentGuideImage;
    private ViewParent viewParent;

    /**
     *

    public void  init(final Activity activity,int currentLayoutId,ArrayList<Integer> lists,INotify iNotify){
        this.activity =activity;
        this.lists =lists;
        this.currentLayoutId=currentLayoutId;
        this.iNotify =iNotify;
    }
    public void guide() {
        View view = activity.getWindow().getDecorView().findViewById(currentLayoutId);
        if(view==null){
            new RuntimeException("找不到id对应的view,请给当前布局文件的顶级节点添加id为你传递过来的id");
        }
        viewParent = view.getParent();
        if (viewParent instanceof FrameLayout) {
            final FrameLayout frameLayout = (FrameLayout) viewParent;
            if (nextResouceIndex <lists.size()) {//设置了引导图片
                currentGuideImage = new ImageView(activity);
                FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.FILL_PARENT);
                currentGuideImage.setLayoutParams(params);
                currentGuideImage.setScaleType(ImageView.ScaleType.CENTER_CROP);
                currentGuideImage.setImageResource(lists.get(nextResouceIndex));
                currentGuideImage.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        nextResouceIndex++;
                        frameLayout.removeView(v);
                        guide();
                    }
                });
                frameLayout.addView(currentGuideImage);//添加引导图片

            } else {
                //已经完毕了
                Log.i(TAG,"引导完毕");
                currentGuideImage=null;
                iNotify.onNotify(null);
//                SPUtils.setValue(getApplicationContext(), ParamConstant.STR_FIRST_RUN, false);//设为已引导
            }
        }else{
            Log.i(TAG,"无法引导! viewParent:"+ viewParent);
        }
    }

    /**
     * 当不小心弹出了引导但是要关闭
     */
    public void canelGuide(){
            if(currentGuideImage!=null && viewParent!=null && currentGuideImage.getParent()!=null && viewParent instanceof  ViewGroup){
                ((ViewGroup) viewParent).removeView(currentGuideImage);
                currentGuideImage=null;
            }
    }
    public boolean guideIsShow(){
        return currentGuideImage!=null;
    }
}

INotify.java 其实就是个回调接口 

package space.qssq.interfaces;

/**
 * Created by luozheng on 15/12/2.
 */
public interface INotify<T> {
     void onNotify(T param);
}

用法:

第一步:给那个用的activity的顶级加一个id,其实你也可以给一个android 根id,叫啥来着,R.id.content_view???反正都可以的,只要不是线性布局等影响显示就好了.

下面是直接添加图片资源id了。也就是你每给添加一个id,它都会new一个图片...

if(SPUtils.getValue(this, ParamConstant.SP_GUIDE_7_8_ChatActivity,false)){//sp的判断不用说了吧..
   <strong> GuidePageEngine guidePageEngine=new GuidePageEngine();</strong>
    ArrayList<Integer> listGuide=new ArrayList<>();
    listGuide.add(R.drawable.guide_7_friend);
    listGuide.add(R.drawable.guide_8_gift);
    guidePageEngine.init(ConversationActivity.this, R.id.my_content_view, listGuide, new INotify() {
        @Override
        public void onNotify(Object o) {

//执行完毕了
            SPUtils.setValue(MainActivity.this,ParamConstant.SP_GUIDE_7_8_ChatActivity,true);
        }
    });
}

能用图片肯定直接给布局文件也是可以的，修改engine为直接读取布局资源，inflate一个view然后add进去就行了一样的道理..不过我们公司的太懒直接给整个屏幕的引导图片.
