recycleview双列表联动卡顿问题一直没解决,今天找了个检测卡顿原因的神器,附上地址
https://github.com/markzhai/AndroidPerformanceMonitor
集成步骤先简单,
1.加依赖

 compile 'com.github.markzhai:blockcanary-android:1.5.0'

2.新建一个类

package com.huarenbang.zndc.utils;

import android.content.Context;

import com.github.moduth.blockcanary.BlockCanaryContext;
import com.github.moduth.blockcanary.internal.BlockInfo;

import java.io.File;
import java.util.LinkedList;
import java.util.List;

/**

 * 检测卡顿
 */
public class AppBlockCanaryContext extends BlockCanaryContext {

    /**
     * Implement in your project.
     *
     * @return Qualifier which can specify this installation, like version + flavor.
     */
    public String provideQualifier() {
        return "unknown";
    }

    /**
     * Implement in your project.
     *
     * @return user id
     */
    public String provideUid() {
        return "uid";
    }

    /**
     * Network type
     *
     * @return {@link String} like 2G, 3G, 4G, wifi, etc.
     */
    public String provideNetworkType() {
        return "unknown";
    }

    /**
     * Config monitor duration, after this time BlockCanary will stop, use
     * with {@code BlockCanary}'s isMonitorDurationEnd
     *
     * @return monitor last duration (in hour)
     */
    public int provideMonitorDuration() {
        return -1;
    }

    /**
     * Config block threshold (in millis), dispatch over this duration is regarded as a BLOCK. You may set it
     * from performance of device.
     *
     * @return threshold in mills
     */
    public int provideBlockThreshold() {
        return 1000;
    }

    /**
     * Thread stack dump interval, use when block happens, BlockCanary will dump on main thread
     * stack according to current sample cycle.
     * <p>
     * Because the implementation mechanism of Looper, real dump interval would be longer than
     * the period specified here (especially when cpu is busier).
     * </p>
     *
     * @return dump interval (in millis)
     */
    public int provideDumpInterval() {
        return provideBlockThreshold();
    }

    /**
     * Path to save log, like "/blockcanary/", will save to sdcard if can.
     *
     * @return path of log files
     */
    public String providePath() {
        return "/blockcanary/";
    }

    /**
     * If need notification to notice block.
     *
     * @return true if need, else if not need.
     */
    public boolean displayNotification() {
        return true;
    }

    /**
     * Implement in your project, bundle files into a zip file.
     *
     * @param src  files before compress
     * @param dest files compressed
     * @return true if compression is successful
     */
    public boolean zip(File[] src, File dest) {
        return false;
    }

    /**
     * Implement in your project, bundled log files.
     *
     * @param zippedFile zipped file
     */
    public void upload(File zippedFile) {
        throw new UnsupportedOperationException();
    }


    /**
     * Packages that developer concern, by default it uses process name,
     * put high priority one in pre-order.
     *
     * @return null if simply concern only package with process name.
     */
    public List<String> concernPackages() {
        return null;
    }

    /**
     * Filter stack without any in concern package, used with @{code concernPackages}.
     *
     * @return true if filter, false it not.
     */
    public boolean filterNonConcernStack() {
        return false;
    }

    /**
     * Provide white list, entry in white list will not be shown in ui list.
     *
     * @return return null if you don't need white-list filter.
     */
    public List<String> provideWhiteList() {
        LinkedList<String> whiteList = new LinkedList<>();
        whiteList.add("org.chromium");
        return whiteList;
    }

    /**
     * Whether to delete files whose stack is in white list, used with white-list.
     *
     * @return true if delete, false it not.
     */
    public boolean deleteFilesInWhiteList() {
        return true;
    }

    /**
     * Block interceptor, developer may provide their own actions.
     */
    public void onBlock(Context context, BlockInfo blockInfo) {

    }
}

3.在application的oncreate方法里加上:

  BlockCanary.install(this, new AppBlockCanaryContext()).start();

然后运行就行,有点像leak这个.
最后我发现原因是加载图片Glide的问题,我看下提示的代码行,

 Glide.with(MyApplication.getContext()).load(mlist.get(position).getImg()).into(holder.ig_image);

adapter里这个context我直接给的是application的,貌似已经知道了,改成从adapter的构造器传进来的context试试
ok,完美,已经解决.上图:
