我想我只是解决了这个问题，在。 java的。删除了setContentView（R.layout.activity_main）下的所有内容;错走了，现在...

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
    setSupportActionBar(toolbar); 

    FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab); 
    fab.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG) 
        .setAction("Action", null).show(); 
     } 
    }); 
}

     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
     setSupportActionBar(toolbar); 

     FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab); 
     fab.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) {

         .setAction("Action", null).show(); 
      } 
     }); 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.menu_main, menu); 
     return true; 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     // Handle action bar item clicks here. The action bar will 
     // automatically handle clicks on the Home/Up button, so long 
     // as you specify a parent activity in AndroidManifest.xml. 
     int id = item.getItemId(); 

     //noinspection SimplifiableIfStatement 
     if (id == R.id.action_settings) { 
      return true; 
     } 

     return super.onOptionsItemSelected(item); 
    } 
}

如果您需要关于此问题的更多信息，请告知我，这是And的新安装roid Studio

什么是你的android项目minSDk和targetSdkVersion？ – Inducesmile

Rendering Problem 
The following classes could not be instantiated: 

android.support.desitn.widget.FloatingActionButton (open class, show exception, clear cache)

某处你有一个错字，写了“desitn”而不是“design”（android.support。 desitn .widget.FloatingActionButton）。

对.java文件进行编辑并且错误消失，请在编辑时查看原始文章。似乎错误消失了，我也只是在帖子中输入了这个错字。谢谢 –

这就是为什么你剪切和粘贴，绝不会重新输入错误信息。 –

我想你忘记了贴activity_main.xml中的文件，确保文件看起来像这样（通过向导创建）

<?xml version="1.0" encoding="utf-8"?>

<android.support.design.widget.AppBarLayout 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:theme="@style/AppTheme.AppBarOverlay"> 

    <android.support.v7.widget.Toolbar 
     android:id="@+id/toolbar" 
     android:layout_width="match_parent" 
     android:layout_height="?attr/actionBarSize" 
     android:background="?attr/colorPrimary" 
     app:popupTheme="@style/AppTheme.PopupOverlay" /> 

</android.support.design.widget.AppBarLayout> 

<include layout="@layout/content_main" /> 

<android.support.design.widget.FloatingActionButton 
    android:id="@+id/fab" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:layout_gravity="bottom|end" 
    android:layout_margin="@dimen/fab_margin" 
    android:src="@android:drawable/ic_dialog_email" />

我有相同的问题随着Android Studio的全新安装。对build.gradle（Module：app）文件的最后几行进行的以下更改似乎已对其进行了更正。（这种变化是基于通过没有表现出这个问题最近的样本项目看）：

原文：

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

更改为：

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

谢谢，这解决了这个问题。 – Alice

这为我解决了它。为什么23.2.0有这个问题？有谁知道？ –

首先，你需要改变这一行在你的构建中。gradle这个

从

compile 'com.android.support:design:23.2.0'

到

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

然后去：

Build -> Clean Project 
Build -> Rebuild Project

上述步骤解决了这个问题对我来说...好运气。
