andorid实现pdf批注、笔记demo
Andorid实现pdf批注、笔记demo
1、兴建andorid项目
2、导入pdf包
implementation ‘com.lonelypluto:pdf-viewer:1.0.5’
1、创建页面和java类
1.1创建OutlineAdapter
package com.example.myapplication.adapter;
import android.content.Context;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import com.artifex.mupdfdemo.OutlineItem;
import com.example.myapplication.R;
/**
* @Description: 文件目录adapter
* @author: ZhangYW
* @time: 2019/1/22 11:17
*/
public class OutlineAdapter extends RecyclerView.Adapter {
private Context mContext;
private OutlineItem mList[];
public OutlineAdapter(Context context, OutlineItem mList[]){
this.mContext = context;
this.mList = mList;
}
/**
* 渲染具体的ViewHolder
* @param parent ViewHolder的容器
* @param viewType 一个标志，我们根据该标志可以实现渲染不同类型的ViewHolder
* @return
*/
@Override
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(mContext).inflate(R.layout.outline_item,parent,false);
return new OutlineViewHolder(itemView);
}
/**
* 绑定ViewHolder的数据。
* @param holder
* @param position 数据源list的下标
*/
@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, final int position) {
OutlineItem bean = mList[position];
if (null == bean)
return;
OutlineViewHolder viewHolder = (OutlineViewHolder) holder;
int level = bean.level;
if (level > 8) level = 8;
String space = "";
for (int i=0; i 1.2创建OutlineAdapter的outline_item.xml页面
1.3创建OnRecyclerItemClickListener
package com.example.myapplication.widget;
import android.support.v4.view.GestureDetectorCompat;
import android.support.v7.widget.RecyclerView;
import android.view.GestureDetector;
import android.view.MotionEvent;
import android.view.View;
/**
* RecyclerView监听事件
*/
public abstract class OnRecyclerItemClickListener implements RecyclerView.OnItemTouchListener {
private GestureDetectorCompat mGestureDetector;
private RecyclerView recyclerView;
public OnRecyclerItemClickListener(RecyclerView recyclerView) {
this.recyclerView = recyclerView;
mGestureDetector = new GestureDetectorCompat(recyclerView.getContext(), new ItemTouchHelperGestureListener());
}
@Override
public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e) {
mGestureDetector.onTouchEvent(e);
return false;
}
@Override
public void onTouchEvent(RecyclerView rv, MotionEvent e) {
mGestureDetector.onTouchEvent(e);
}
@Override
public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {
}
private class ItemTouchHelperGestureListener extends GestureDetector.SimpleOnGestureListener {
@Override
public boolean onSingleTapUp(MotionEvent e) {
View child = recyclerView.findChildViewUnder(e.getX(), e.getY());
if (child != null) {
RecyclerView.ViewHolder vh = recyclerView.getChildViewHolder(child);
onItemClick(vh);
}
return true;
}
@Override
public void onLongPress(MotionEvent e) {
View child = recyclerView.findChildViewUnder(e.getX(), e.getY());
if (child != null) {
RecyclerView.ViewHolder vh = recyclerView.getChildViewHolder(child);
onItemLongClick(vh);
}
}
}
public abstract void onItemClick(RecyclerView.ViewHolder vh);
public abstract void onItemLongClick(RecyclerView.ViewHolder vh);
}
1.4创建OutlineActivity
package com.example.myapplication.activity;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import com.artifex.mupdfdemo.OutlineActivityData;
import com.artifex.mupdfdemo.OutlineItem;
import com.example.myapplication.R;
import com.example.myapplication.adapter.OutlineAdapter;
import com.example.myapplication.widget.OnRecyclerItemClickListener;
/**
* @Description: 目录
* @author: ZhangYW
* @time: 2019/3/8 10:29
*/
public class OutlineActivity extends AppCompatActivity {
private RecyclerView recyclerView;
private OutlineAdapter adapter;
private OutlineItem mItems[];
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_outline);
initData();
initView();
setListener();
}
/**
* 初始化数据
*/
private void initData(){
mItems = OutlineActivityData.get().items;
}
/**
* 初始化布局
*/
private void initView(){
adapter = new OutlineAdapter(this,mItems);
recyclerView = (RecyclerView)findViewById(R.id.outline_rv);
recyclerView.setHasFixedSize(true);
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(this);
linearLayoutManager.setOrientation(LinearLayoutManager.VERTICAL);//HORIZONTAL 水平
recyclerView.setLayoutManager(linearLayoutManager);
recyclerView.setAdapter(adapter);
}
/**
* 设置点击事件
*/
private void setListener(){
recyclerView.addOnItemTouchListener(new OnRecyclerItemClickListener(recyclerView) {
@Override
public void onItemClick(RecyclerView.ViewHolder vh) {
OutlineActivityData.get().position = vh.getLayoutPosition();
setResult(mItems[vh.getLayoutPosition()].page);
finish();
}
@Override
public void onItemLongClick(RecyclerView.ViewHolder vh) {
}
});
}
}
1.5创建OutlineActivity的activity_outline.xml页面

1.14创建MoreSetActivity的activity_more_set.xml页面
1.15 activity配置
1.16 设置文件权限
1.17 java文件展示
1.18 xml文件展示
1.19运行项目报错
Manifest merger failed : uses-sdk:minSdkVersion 16 cannot be smaller than version 17 declared in library [com.lonelypluto:pdf-viewer:1.0.5] C:\Users\yangkai.gradle\caches\transforms-1\files-1.1\pdf-viewer-1.0.5.aar\26470ca641a88cc4ca3b1dd0fff680b9\AndroidManifest.xml as the library might be using APIs not available in 16
Suggestion: use a compatible library with a minSdk of at most 16,
or increase this project’s minSdk version to at least 17,
or use tools:overrideLibrary=“com.lonelypluto.pdflibrary” to force usage (may lead to runtime failures)
需要修改sdk:minSdkVersion 版本：
这里我修改为19，运行正常
打包运行正常
提示访问文件
1.19 如果文件不能打开
提示：Permission denied，需要设置手机或平板的存储储存权限
首先提示访问文件权限已经设置
平板为例设置权限：设置=>应用管理=>高级=>应用权限=>存储=>找到对应的app打开权限
3 成功效果
注意：权限是手机和代码都需要设置权限，才能完成pdf的读取
会存在的问题：ObjectBox的包和pdf的包存在不兼容性，会导致pdf运行失败！
