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：

package="com.example.proyecto_1"

android:versionCode="1"

android:versionName="1.0" >

android:minSdkVersion="7"

android:targetSdkVersion="15" />

android:icon="@drawable/ic_launcher"

android:label="@string/app_name"

android:theme="@style/AppTheme" android:hasCode="false" android:allowTaskReparenting="false">

android:name=".MainActivity"

android:label="@string/title_activity_main" >

我不知道我做错了什么,我找到了解决方案,但我不能,请帮助我.

解决方法:

您的错误有很多可能性.

>首先把(.)DOT引导你的TestScrn1活动声明

机器人.

>确保清单中的android：hasCode未设置为false

文件.

>清理您的项目并再次运行.

> Tick项目>自动构建.
