Question

这是我的大问题:

和代码:

package org.madmax.sudoku;

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

public class SudokuActivity extends Activity implements OnClickListener {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        //Set up Click Listener for all Buttons
        View continueButton = findViewById(R.id.continue_button);
        continueButton.setOnClickListener(this);
        View newButton = findViewById(R.id.new_button);
        newButton.setOnClickListener(this);

        public void onClick(View v) {
            switch(v.getId()) {
            case R.id.about_button:
                Intent i = new Intent(this, About.class);
                startActivity(i);
                break;
            }
        }

    }
}

错误是:

-void is an invalid type for the variable onCLick()

为什么 Eclipse 会给我这个错误？

您可以像这样在 onCreate 方法中使用 onclick

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



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

        public void onClick(View v) {
            // your code here

        }
    });
}
