二次采样的工具类:

public class ImaegUtil {
    public interface CallBack{
        void getdata(Bitmap bitmap);
    }
    public static void yibu(String uri, final int width, final int height, final CallBack callBack){

                return ImaegUtil.ercicaiyang(strings[0],width,height);
            }

            @Override
            protected void onPostExecute(Bitmap bitmap) {
                callBack.getdata(bitmap);
            }
        }.execute(uri);
    }
    //二次采样
    public static Bitmap ercicaiyang(String uri,int width,int height){

        BitmapFactory.Options options = new BitmapFactory.Options();
        //第一次只加载宽高信息
        options.inJustDecodeBounds=true;
        BitmapFactory.decodeFile(uri,options);
        //根据图片原始宽高 和请求宽高 计算采样率
        options.inSampleSize=Math.max(options.outWidth/width,options.outHeight/height);
        //第二次加载图片
        options.inJustDecodeBounds=false;
        Bitmap bitmap = BitmapFactory.decodeFile(uri, options);
        return bitmap;
    }
}

Fragmentleft：

public class Fragmentleft extends BaseFragment {

    private Letfadapter letfadapter;
    private ListView listView;
    private final int ZHI=100;
    @Override
    protected void initData() {
        List<String> list=new ArrayList<>();
        list.add("首页");
        list.add("电影");
        list.add("消息");
        letfadapter.setList(list);
    }

    @Override
    protected void initView(View view) {
        listView = view.findViewById(R.id.listview);
        letfadapter = new Letfadapter(getActivity());
        listView.setAdapter(letfadapter);
        //条目点击
        listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                //判断下标是否为0
                if (position==0){
                    Intent intent=new Intent(Intent.ACTION_PICK);
                    intent.setType("image/*");
                    startActivityForResult(intent,ZHI);
                }
                //点击切换到哪个界面
                ((MainActivity)getActivity()).cc(position-1);
            }
        });
    }

    @Override
    public int getLayoutResId() {
        return R.layout.fragmentleft;
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode==ZHI&&resultCode==getActivity().RESULT_OK){
            Uri uri=data.getData();
            progeressImage(Url2path(uri));
        }
    }
    //二次采样并把图片传给适配器
    private void progeressImage(String imagePath) {
        int size = getResources().getDimensionPixelSize(R.dimen.leftIconSize);
        ImaegUtil.yibu(imagePath, size, size, new ImaegUtil.CallBack() {
            @Override
            public void getdata(Bitmap bitmap) {
                letfadapter.setBitmap(bitmap);
            }
        });
    }

    //Uri转换为字符流
    private String Url2path(Uri uri) {
        String[] proj={MediaStore.Images.Media.DATA};
        CursorLoader loader = new CursorLoader(getActivity(), uri, proj, null, null, null);
        Cursor cursor = loader.loadInBackground();
        int columnIndexOrThrow = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        return cursor.getString(columnIndexOrThrow);
    }
}

string文件夹创建dimen.xml:

<resources>
    <dimen name="leftIconSize">100dp</dimen>
</resources>

tab布局的适配器：

public class Mainadapter extends FragmentPagerAdapter {
    private String[] ming=new String[]{"首页","电影","我的"};

        super(fm);
    }
    @Override

        switch (i){
            case 0:
                return new Fragmentone();
            case 1:
                return new Fragmenttwo();
            case 2:
                return new Fragmentthree();
        }
        return null;
    }

    @Nullable
    @Override
    public CharSequence getPageTitle(int position) {
        return ming[position];
    }

    @Override
    public int getCount() {
        return ming.length;
    }
}

        toggle = new ActionBarDrawerToggle(this,draw,R.string.open,R.string.close);
        draw.addDrawerListener(toggle);
        toggle.syncState();
        //往侧滑里添加fragment
        if (savedInstanceState==null){
            getSupportFragmentManager().beginTransaction()
                    .add(R.id.frame,new Fragmentleft())
                    .commit();
        }
        //获取资源ID
        viewPager = findViewById(R.id.viewpager);

        //设置适配器
        viewPager.setAdapter(new Mainadapter(getSupportFragmentManager()));
        //根据viewpager设置TabLayout
        tab.setupWithViewPager(viewPager);
    }
    //点击切换到哪个界面
    public void cc(int posintion){

        draw.closeDrawer(Gravity.START);
    }
    @Override

            return true;

配置图片：

        //格式配置
        DisplayImageOptions options=new DisplayImageOptions.Builder()

                .memoryCacheSizePercentage(10)
                .diskCacheSize(20*1024*1024)
                .defaultDisplayImageOptions(options)
                .build();
        //初始化
        ImageLoader.getInstance().init(configuration);

创建数据库：

public class SqliteHelper extends SQLiteOpenHelper {

    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
