java - 用按钮错误链接两个 Java Activity ! "Android Studio"

Question

嗨，我对 Java 很陌生，您能告诉我哪里出了问题吗？我将不胜感激，非常感谢!我想在按下按钮时链接两个 java Activity

<小时/>

package com.example.matt.androidui;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Button;


public class MainActivity extends Activity {

在 Activity 顶部调用。

我遇到问题的代码似乎出了问题!

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

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

    public void onClick (View v){

        Intent intent = new Intent (v.getContext(), MainActivity2Activity.class);
        startActivityForResult(kntent, 0);
    }
  }
}

按钮代码到此结束!

@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) {

    int id = item.getItemId();

    // noinspection SimplifiableIfStatement

    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}
}

如果您想通过按下按钮开始第二个 Activity ，则只需执行此操作即可，

Intent intent = new Intent (MainActivity.this, SecondActivity.class);
startActivity(intent);
