我知道以前肯定已经回答过这个问题，但是我已经连续两个晚上做了这个工作，我要么听不懂，要么就搞砸了. 我试图用按钮调用方法.我的方法仅是复制和粘贴，因此不会打开其他活动.

I know this has certainly been answered before, but I have been working on this for two straight nights and I either don't understand or I have messed something up badly. I am trying to call a method with a button. My method is only going to copy and paste so it's not opening another activity.

package com.example.copypastetest;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class PDFtester extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_pdftester);
            Button b1 = (Button) findViewById(R.id.button2);
            b1.setOnClickListener(new OnClickListener(){;

        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub
            //public void work (View view){
    this is my issue??-->Intent intent = new Intent(this, copyAsset.class);
            startActivity(intent);}         
        }

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.activity_pdftester, menu);
        return true;}
    };

感谢您的关注，我承认我完全是个黑客.我到目前为止做的唯一原因是这个网站，第一个问题，我相信很多人，但希望有人能提供帮助.我不是要当吸血鬼，但如果有可以阅读的页面，我能全力以赴，那么我真的是在这里寻找正确的答案.

thank you for looking, I admit I am a total hack. The only reason I made it this far is this website, first question, im sure of many but hopefully someone can help. I am not trying to be a vampire but I really am looking for the correct answer here if there is a page i can read to understand what i did wrong i am all ears.

谢谢.

推荐答案

使用以下代码:

    @Override
    public void onClick(View view) {
        // TODO Auto-generated method stub
        //public void work (View view){
        Intent intent = new Intent(PDFtester.this, copyAsset.class);
        startActivity(intent);}         
    }

注意:-诸如OnClickListener，OnTouchListener等的接口不使用this来获取Context尝试使用YourActivity.this或getApplicationContext()

Note :- Interfaces like OnClickListener,OnTouchListener etc don't use this for getting Context try to use YourActivity.this or getApplicationContext()
