我正在开发一款具有带滑动功能的Tab的应用。我正在使用Eclipse进行开发。我已通过Property将support design library
导入为Library。在运行期间,我不断收到此错误" Error inflating class android.support.design.widget.CoordinatorLayout
"。
android support design.jar
并尝试了,这是行不通的class.jar
support design library
文件{J} ava build path
support design library
Properties->Android->Add Library
导入Theme.AppCompat.Light.DarkActionBar
作为库,这也无效<style name="MyMaterialTheme.Base" parent="Theme.AppCompat.Light.DarkActionBar">
&#34; &#34; AppCompatActivity
&#34;
我正在扩展import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.widget.Button;
import com.example.scrollingtab.R;
public class MainActivity extends AppCompatActivity implements View.OnClickListener {
private Toolbar toolbar;
private Button btnSimpleTabs, btnScrollableTabs, btnIconTextTabs, btnIconTabs, btnCustomIconTextTabs;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
btnSimpleTabs = (Button) findViewById(R.id.btnSimpleTabs);
btnSimpleTabs.setOnClickListener(this);
}
,请参阅我的MainActivity.Java
package com.example.scrollingtab.activity;

答案 1 :(得分:11)
对我来说,此错误是由于使用了某些 androidx
库而导致的,但随后在某些layout.xml
文件中仍具有旧的坐标布局。
build.gradle
:
com.android.support:coordinatorlayout
-> androidx.coordinatorlayout:coordinatorlayout:1.0.0-alpha1
如果您使用的是androidx
,那么也许也是您的问题。
我还必须更新其他v7
库,例如Toolbar
。
在此处查看androidx
迁移指南:https://developer.android.com/topic/libraries/support-library/refactor
答案 2 :(得分:5)
在迁移到AndroidX时出现此错误
要解决,我做到了:
,如@Mikeumus所建议-并将其添加到模块的build.gradle依赖项中:
实现“ androidx.coordinatorlayout:coordinatorlayout:latest.version.here”
检入Layout XML文件(您尝试使用 setContentView
如果布局包含:
<< strong> android.support.design.widget.CoordinatorLayout
...
替换为: <androidx.coordinatorlayout.widget.CoordinatorLayout
</android.support.design.widget.CoordinatorLayout>
使用
</androidx.coordinatorlayout.widget.CoordinatorLayout>
答案 3 :(得分:3)
我找到了eclipse的解决方案
我遇到的问题是{/ 1}}文件未在gen /文件夹中的 support.design 下生成。
执行以下步骤后,生成R.Java
文件。主要问题是设计库目标为22.更改为23工作。
将支持设计库从R.Java
导入到eclipse工作区。
打开 AppCompat 和设计库的\sdk\extras\android\support\design
并将其定位到 23
清除 Appcompat ,设计和您的项目。

确保在您的活动中设置主题AppCompat
<activity
android:name=".newApp.screens.main.MainActivity"
android:label="@string/title_activity_main_launch"
android:theme="@style/AppThemes"></activity>
<!-- Base application theme. -->
<style name="AppThemes" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#673AB7</item>
<item name="colorPrimaryDark">#512DA8</item>
