Question

一切正常，直到我更新了我的gradle文件，现在我的tablayout由于错误而崩溃：

Java.lang.NoClassDefFoundError：解析失败：Landroid / support / v7 / widget / TintManager; 在android.support.design.widget.TabLayout $ TabView。（TabLayout.java:1185）在android.support.design.widget.TabLayout.createTabView（TabLayout.java:656）在android.support.design.widget.TabLayout.addTabView（TabLayout.java:695）在android.support.design.widget.TabLayout.addTab（TabLayout.java:386）在android.support.design.widget.TabLayout.addTab（TabLayout.java:361）在android.support.design.widget.TabLayout.setTabsFromPagerAdapter（TabLayout.java:645）在android.support.design.widget.TabLayout.setupWithViewPager（TabLayout.java:616） at com.example.ScrollableTabsActivity.onCreate（ScrollableTabsActivity.java:307）在android.app.Activity.performCreate（Activity.java:6033）在android.app.Instrumentation.callActivityOnCreate（Instrumentation.java:1106）在android.app.ActivityThread.performLaunchActivity（ActivityThread.java:2288）在android.app.ActivityThread.handleLaunchActivity（ActivityThread.java:2397）在android.app.ActivityThread.access $ 800（ActivityThread.java:151）在android.app.ActivityThread $ H.handleMessage（ActivityThread.java:1310）在android.os.Handler.dispatchMessage（Handler.java:102）在android.os.Looper.loop（Looper.java:135）在android.app.ActivityThread.main（ActivityThread.java:5268） at java.lang.reflect.Method.invoke（Native Method）在java.lang.reflect.Method.invoke（Method.java:372）在com.android.internal.os.ZygoteInit $ MethodAndArgsCaller.run（ZygoteInit.java:902）在com.android.internal.os.ZygoteInit.main（ZygoteInit.java:697）引起：java.lang.ClassNotFoundException：路径上没有找到类“android.support.v7.widget.TintManager”：DexPathList [[zip file“/data/app/com.example-1/base.apk”] ，nativeLibraryDirectories = [/ vendor / lib，/ system / lib]] 在dalvik.system.BaseDexClassLoader.findClass（BaseDexClassLoader.java:56） at java.lang.ClassLoader.loadClass（ClassLoader.java:511） at java.lang.ClassLoader.loadClass（ClassLoader.java:469）在android.support.design.widget.TabLayout $ TabView。（TabLayout.java:1185）在android.support.design.widget.TabLayout.createTabView（TabLayout.java:656）在android.support.design.widget.TabLayout.addTabView（TabLayout.java:695）在android.support.design.widget.TabLayout.addTab（TabLayout.java:386）在android.support.design.widget.TabLayout.addTab（TabLayout.java:361）在android.support.design.widget.TabLayout.setTabsFromPagerAdapter（TabLayout.java:645）在android.support.design.widget.TabLayout.setupWithViewPager（TabLayout.java:616）

这是我的gradle文件

apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "23.0.2"

defaultConfig {
    applicationId "com.example"
    minSdkVersion 11
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.2.1'

compile 'com.daimajia.easing:library:1.0.1@aar'
compile 'com.daimajia.androidanimations:library:1.1.3@aar'
compile project(':lib')
}

请帮帮我错误

Answer 1

更改依赖项就行了，只需将com.android.support:support-v4:23.2.0和更新的构建工具版本添加到23.0.2

compile 'com.android.support:appcompat-v7:23.2.0'
compile 'com.android.support:design:23.2.0'
compile 'com.android.support:recyclerview-v7:23.2.0'
compile 'com.android.support:support-v4:23.2.0'
compile 'com.android.support:cardview-v7:23.2.0'

我不知道为什么有些人认为我的问题是否定的，反正这可能对某人有帮助

所有支持库必须具有相同的版本。 23.2.1或23.1.1或其他任何东西，但你不能混合版本。

ext.supportLibVersion = "23.2.1"
// design includes recyclerview-v7 and appcompat-v7, which includes support-v4
compile "com.android.support:design:$supportLibVersion"
compile "com.android.support:cardview-v7:$supportLibVersion"

首先创建一个新活动但不是空活动，然后选择标签活动，然后像我一样做..

步骤1：创建三个片段活动首先从每个片段活动中删除所有内容，然后将此代码写入每个活动

package com.yourpakagename.tabedactivity;
import android.content.Context;
import android.net.Uri;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;


public class layout1 extends Fragment {
public layout1() {
// Required empty public constructor
}


@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                     Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_layout12, container, false);
//changes in each activity-->R.layout.fragment_layout_name<----
}
}

第2步：最后在标签式活动中我们不需要这两个功能

  public static class PlaceholderFragment extends Fragment {

private static final String ARG_SECTION_NUMBER = "section_number";

public PlaceholderFragment() {
}


public static PlaceholderFragment newInstance(int sectionNumber) {
    PlaceholderFragment fragment = new PlaceholderFragment();
    Bundle args = new Bundle();
    args.putInt(ARG_SECTION_NUMBER, sectionNumber);
    fragment.setArguments(args);
    return fragment;
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.fragment_main, container, false);
    TextView textView = (TextView) rootView.findViewById(R.id.section_label);
    textView.setText(getString(R.string.section_format, getArguments().getInt(ARG_SECTION_NUMBER)));
    return rootView;
}
}

第3步：最后使用此代码更改您的sectionpageradapter函数 - ＆gt;

public class SectionsPagerAdapter extends FragmentPagerAdapter {

public SectionsPagerAdapter(FragmentManager fm) {
    super(fm);
}

@Override
public Fragment getItem(int position) {
    // getItem is called to instantiate the fragment for the given page.
    // Return a PlaceholderFragment (defined as a static inner class below).
    //delete  return PlaceholderFragment.newInstance(position + 1);
    switch (position)
    {
        case 0:
            return new layout1();
        case 1:
            return new layout2();
        case 2:
            return new layout3();
        default:
            return  new layout1();
    }
}

@Override
public int getCount() {
    // Show 3 total pages.
    return 3;
}

@Override
public CharSequence getPageTitle(int position) {
    switch (position) {
        case 0:
            return "SECTION 1";
        case 1:
            return "SECTION 2";
        case 2:
            return "SECTION 3";
    }
    return null;
 }
 }

将支持库更新到23.2.1后，TabLayout崩溃
