java - 由 : java. lang.NoSuchFieldError : android. support.v7.appcompat 引起

标签 java android android-appcompat

使用这段代码:

package com.example.newsapp;

import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

public class MainActivity extends ActionBarActivity {

    private Button mTrueButton;
    private Button mFalseButton;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

            mTrueButton = (Button)findViewById(R.id.true_button);
            mTrueButton.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                            Toast.makeText(MainActivity.this,
                                            R.string.correct_toast,
                                            Toast.LENGTH_SHORT).show();


                    }
            });
            mFalseButton = (Button)findViewById(R.id.true_button);
            mFalseButton.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                            Toast.makeText(MainActivity.this,
                                            R.string.incorret_toast,
                                            Toast.LENGTH_SHORT).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.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();
            if (id == R.id.action_settings) {
                    return true;
            }
            return super.onOptionsItemSelected(item);


    }

}

还有这个 XML:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.newsapp"
android:versionCode="1"

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

</manifest>

我收到以下错误:

我在网上搜索并找到了不同的“解决方案”，但没有一个对我有用。 有什么建议么？对此日志的一些见解将不胜感激，当我尝试启动它时它就崩溃了

最佳答案

<强>1。将依赖项导入 Maven 仓库

如果您使用的是 Maven 和默认存储库，则 appcompat 库已过时。将库从您的 Android SDK 手动导入到您的本地存储库中，然后重试。 (旧的appcompat是508KB，Android SDK的是497KB)

要导入 jar(指定 Android SDK 的正确路径):

mvn install:install-file -Dfile=/path/to/sdk/extras/android/compatibility/v7/appcompat/libs/android-support-v7-appcompat.jar -DgroupId=com.google.android -DartifactId=support-v7-appcompat -Dversion=r21 -Dpackaging=jar

然后在您的 pom 文件中添加依赖项:

<dependency>
   <groupId>com.google.android</groupId>
   <artifactId>support-v7-appcompat</artifactId>
   <version>r21</version>
   <type>jar</type>
   <scope>compile</scope>
</dependency>

<强>2。或者查看使用 Maven Android SDK 部署程序: https://github.com/simpligility/maven-android-sdk-deployer
