错误:包 android.support.design.widget 不存在 [英] error: package android.support.design.widget does not exist

问题描述

我是安卓新手.当我想将一个项目导入我的 android studio 时，它会抱怨这个错误:错误包 android.support.design.widget 不存在

i'm new to android. when i want to import a project into my android studio it complain about this error that : error package android.support.design.widget does not exist

这是我的代码:

public class CatalogActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_catalog);

// Setup FAB to open EditorActivity
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        Intent intent = new Intent(CatalogActivity.this, EditorActivity.class);
        startActivity(intent);
    }
});
}
}

这是我的 build.gradle:

and this is my build.gradle:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
buildToolsVersion "25.0.2"

defaultConfig {
    applicationId "com.example.android.pets"
    minSdkVersion 16
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}
}

dependencies {
     compile fileTree(include: ['*.jar'], dir: 'libs')
     testCompile 'junit:junit:4.12'
     compile 'com.android.support:appcompat-v7:25.3.1'
     compile 'com.getbase:floatingactionbutton:1.9.1'
}

我该如何解决这个问题以及另一件事，每次我想将另一个其他项目导入我的 android studio 时，都会出现一堆错误，需要更改 build.gradle 和 build.gradle.properties 并且每次我有这样的问题.谁能给我一个关于这个 build.gradle 的参考资料，以了解它应该如何?

how can i solve this problem and one another thing that every time that i want to import another else project into my android studio there is bunch of error and need to change build.gradle and build.gradle.properties and every time i have some problem like this . can anyone give me a reference about this build.gradle to learn how it should be ?

推荐答案

浮动操作 按钮用于特殊类型的升级操作.所以你需要添加com.android.support:design library在你的 build.gradle 中也包括这一行:

Floating action buttons are used for a special type of promoted action. so you need to add com.android.support:design library Include this line also in your build.gradle:

在你的build.gradle中编译这个dependencies:

compile 'com.android.support:design:25.3.1'
