Question

美好的一天，你能帮助我吗？在模拟器上编译/运行我的代码时出现此错误。这是我过去的示例教程。我使用了最小的Target API - 15并编译了最新的gradle 'com.android.support:design:23.0.0'

http://www.android4devs.com/2015/06/navigation-view-material-design-support.html

代码错误：

AndroidRuntime：java.lang.RuntimeException：无法启动活动ComponentInfo {com.eccp.projects.ecosavers.ecosavers / com.eccp.projects.ecosavers.ecosavers.activities.MainActivity}：android.view.InflateException ：二进制XML文件行＃29：二进制XML文件行＃29：错误膨胀类android.support.design.widget.NavigationView 12-29 06：43：39.409 3448-3448 / com.eccp.projects.ecosavers.ecosavers E / AndroidRuntime：at android.app.ActivityThread.performLaunchActivity（ActivityThread.java:2416)<< em>

E / AndroidRuntime：引起：android.view.InflateException：二进制XML文件行＃29：二进制XML文件行＃29：错误膨胀类android.support.design.widget.NavigationView < / p>
以下是我的代码：MainActivity.java

@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //SET my own toolbar toolbar = (Toolbar) findViewById(R.id.tool_bar); setSupportActionBar(toolbar); getSupportActionBar().setDisplayShowHomeEnabled(true); getSupportActionBar().setHomeButtonEnabled(true); mNavigationView = (NavigationView) findViewById(R.id.navigation_view); mNavigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() { @Override public boolean onNavigationItemSelected(MenuItem menuItem) { if (menuItem.isChecked()) menuItem.setChecked(false); else menuItem.setChecked(true); //Closing drawer on item click mDrawerlayout.closeDrawers(); //Check to see which item was being clicked and perform appropriate action switch (menuItem.getItemId()) { //Replacing the main content with ContentFragment Which is our Inbox View; case R.id.events: Toast.makeText(getApplicationContext(), "Inbox Selected", Toast.LENGTH_SHORT).show(); Eco_events fragment = new Eco_events(); android.support.v4.app.FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction(); fragmentTransaction.replace(R.id.frame, fragment); fragmentTransaction.commit(); return true; // show a toast on click case R.id.activities: Toast.makeText(getApplicationContext(), "Send Selected", Toast.LENGTH_SHORT).show(); return true; case R.id.spam: Toast.makeText(getApplicationContext(), "Spam Selected", Toast.LENGTH_SHORT).show(); return true; default: Toast.makeText(getApplicationContext(), "Somethings Wrong", Toast.LENGTH_SHORT).show(); return true; } } }); // Initializing Drawer Layout and ActionBarToggle mDrawerlayout = (DrawerLayout) findViewById(R.id.drawer); mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerlayout, toolbar, R.string.drawerOpened, R.string.drawerOpened) { @Override public void onDrawerClosed(View drawerView) { // Code here will be triggered once the drawer closes as we dont want anything to happen so we leave this blank super.onDrawerClosed(drawerView); } @Override public void onDrawerOpened(View drawerView) { // Code here will be triggered once the drawer open as we dont want anything to happen so we leave this blank super.onDrawerOpened(drawerView); } }; //Setting the actionbarToggle to drawer layout mDrawerlayout.setDrawerListener(mDrawerToggle); //calling sync state is mDrawerToggle.syncState(); } @Override public boolean onOptionsItemSelected(MenuItem item) { return super.onOptionsItemSelected(item); }

Answer 1

请按照以下步骤操作：

右键点击Project->Open Module Settings。
然后打开“依赖关系”选项卡。
单击+符号，然后选择Library Dependency。您将看到一个名为Choose Library Dependency的弹出窗口。
输入＆＃34; com.android.support＆＃34;。然后单击搜索图标。

现在选择设计库。然后单击“确定”。

感谢您的关注，我很感激。我终于找到了（我）这个问题的答案。

错误膨胀类android.support.design.widget.NavigationView＃28或＃29

对我有用的解决方案是，您必须与support design library和支持AppCompat Library相匹配。在gradle模块中，

更改gradle版本（您想要的库号）您也可以在我给出的链接中找到最新的gradle构建，但我建议您检查您的gradle模块（第2张图片，因为它们是第一次更新gradle构建。然后在我的gradle模块中 - compile: ...已突出显示，这意味着有一个更新的版本，只需更改编号，例如24.0.0编译，如果它是稳定的，而不是预览），平均值我的时间是23.1.1。

- ＆GT; more gradle lib- gradleplease.appspot.com

compile 'com.android.support:appcompat-v7:23.1.1'

compile 'com.android.support:design:23.1.1'

:)它对我有用！

观察（对我而言，当我更改/解决此错误时，值为23.x.x）：如果您的support-design与AppCompat-lib不匹配，则生成＃28 如果您的AppCompat与support-design生成＃29 不匹配。试试吧，也许我会交换＃。

Answer 3

您收到此错误是因为您需要设计支持库。

打开SDK Manager并下载Android Support Repository，而不是在这里找到该库的最新版本：

<android-sdk>/extras/android/m2repository/com/android/support/design/23.0.1/design-23.0.1.aar

将其复制到libs目录中，然后将依赖项添加到build.gradle：

repositories {
    flatDir {
        dirs 'libs'
    }
}

dependencies {
    compile 'android.support.design:design:23.0.1@aar'
}
