我试图制作一个简单的应用程序,我想添加一个新的 Activity,但是当我在模拟器上运行我的应用程序时(Eclipse 没有给我任何错误)它就崩溃了。

这是我的日志:

这是我的 MainActivity:

package com.example.proyecto_1;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity {

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

Button button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
Intent test_scrn1 = new Intent(MainActivity.this, TestScrn1.class);
startActivity(test_scrn1);
}
});

}
}

最后这是我的 AndroidManifest:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.proyecto_1"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
android:minSdkVersion="7"
android:targetSdkVersion="15" />

<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" android:hasCode="false" android:allowTaskReparenting="false">
<activity
android:name=".MainActivity"
android:label="@string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="TestScrn1"></activity>
</application>

我不知道我做错了什么,我一直在寻找解决方案,但我做不到,请帮助我。

最佳答案

您的错误有多种可能性。

  • 首先将 (.)DOT 放在 TestScrn1 Activity 声明的前面机器人。
  • 确保您的 list 中的 android:hasCode 未设置为 false文件。
  • 清理您的项目并再次运行。
  • 勾选项目 > 自动构建。
