Android的工作室1.0.2新项目 - 无法解析符号“ActionBarActivity”新项目、符号、工作室、Android

2023-09-04 23:52:46 作者:荔莞少年。

我很困惑。今天,我刚刚重新安装Android的工作室版本1.0.2(和Android SDK),因为我昨天遇到了一些问题,当我创建了一个新的项目。我希望我能解决这些问题,只需重新安装了一切,但实际上问题依然存在,我不知道如何解决它。

I’m very confused. Today I just reinstalled Android Studio Version 1.0.2 (and the Android SDK) because I had some problems yesterday when I created a new project. I hoped that I could solve them by just reinstall everything, but actually the problem still exists and I don’t know how to solve it.

在我创建了Android的Studio中的一个新项目,并切换到我的MainActivity(我没有在文件中的一个改变任何东西),我总是在文件中显示以下错误。

After I created a new project in Android Studio and switch to my MainActivity (I didn't changed anything in one of the files), I always get the following errors displayed in the file.

MainActivity.class:

package com.android.testapplication;

import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;


public class MainActivity extends ActionBarActivity {

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


    @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);
    }
}

错误:

在无法解析符号ActionBarActivity 在无法解析的方法的onCreate(android.os.Bundle) 在无法解析的方法的setContentView(int)的 在无法解析法getMenuInflater() 在无法解析的方法的setContentView(int)的 在无法解析法onOptionsItemSelected(android.view.MenuItem)

项目:build.gradle

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.0.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

模块:build.gradle

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.android.testapplication"
        minSdkVersion 14
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:21.0.3'
}

我已经重建和清理我的项目,同步工程与摇篮文件但他们没有固定的我的问题。

I already rebuild and cleaned my project and 'Sync Project with Gradle Files' but none of them fixed my issues.

有趣的是,我可以编译和我的智能手机上运行我的项目...

The funny thing is, that I can compile and run my project on my smartphone…

PS:我想这似乎是一个摇篮的问题,因为每当我添加一个新的库,例如'com.google.android.gms:玩-服务:87年6月5日,然后尝试导入'进口com.google.android.gms.gcm.GoogleCloudMessaging; 。我也得到了无法解析符号......显示错误。我没有与GCM服务符合它...

PS: I guess it seems to be a gradle issue, because whenever I add a new library such as 'com.google.android.gms:play-services:6.5.87' and then try to import it 'import com.google.android.gms.gcm.GoogleCloudMessaging;'. I also get the 'Cannot resolve symbol…' error displayed. I didn’t complied it with the GCM Service…

感谢您的帮助提前:)
