Floating Action Button throing Fehler

Question

Ich weiß wirklich nicht, warum mein Programm nicht ausgeführt wird. Ich glaube, ich habe every hier erklärt: FloatingActionButton example with Support Library

my_layout.xml

<android.support.design.widget.CoordinatorLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 


    <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" /> 

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

gradle:

apply plugin: 'com.android.application' 

dependencies { 
    compile fileTree(dir: 'libs', include: '*.jar') 
    compile project(':appcompat_v7') 
    compile 'com.android.support:appcompat-v7:23.1.1' 
    compile 'com.android.support:design:23.1.1' 
} 

android { 
    compileSdkVersion 22 
    buildToolsVersion "22.0.1" 

    sourceSets { 
     main { 
      manifest.srcFile 'AndroidManifest.xml' 
      java.srcDirs = ['src'] 
      resources.srcDirs = ['src'] 
      aidl.srcDirs = ['src'] 
      renderscript.srcDirs = ['src'] 
      res.srcDirs = ['res'] 
      assets.srcDirs = ['assets'] 
     } 

     // Move the tests to tests/java, tests/res, etc... 
     instrumentTest.setRoot('tests') 

     // Move the build types to build-types/<type> 
     // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ... 
     // This moves them out of them default location under src/<type>/... which would 
     // conflict with src/ being used by the main source set. 
     // Adding new build types or product flavors should be accompanied 
     // by a similar customization. 
     debug.setRoot('build-types/debug') 
     release.setRoot('build-types/release') 
    } 

hinzugefügt @ color/floating_action_button_color auf \ AppData \ Local \ Android \ android-sdk \ Plattformen \ android-22 \ data \ res \ values ​​\ themes.xml

aber nach der Ausführung des Programms gibt es immer diesen Fehler:

Jede Idee, wie dieses Problem beheben? Vielen Dank.

Answer 1

ok .... Ich wechselte zu Android Studio ... wow alles funktioniert.

Answer 2

Ihre MyLayoutActivity sollte die AppCompactActivity statt ActionBarActivity verlängern.

Answer 3

Probieren Sie n das Projekt übergeordneten Thema ändern:

<style name="Base.AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
