Question

我问过类似的问题。这段代码的目的是检查核对清单是否被选中，如果它是在分数上加1。我被告知问题在于我还没有举办活动。请解释我需要做些什么来使它工作，我是Android开发的新手，并且已经坚持了几天。请给出答案的代码示例。

package xyz.ashraf.whoisdelasalle;

import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.TextView;
import android.widget.CompoundButton.OnCheckedChangeListener;

/**

public class check_Button extends Pop_sallian{
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.popwindow_sallian);
        // Connects The variable to an xml id


        TextView output = (TextView) findViewById(R.id.output);

        final int[] score = {0};
        //sets the variable to 0



         OnCheckedChangeListener checkedListener = new OnCheckedChangeListener() {

            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                switch(buttonView.getId()){
                    case R.id.concern:
                        score[0]++;
                        break;
                    case R.id.faith:
                        score[0]++;
                        break;
                    case R.id.respect:
                        score[0]++;
                        break;
                    case R.id.education:
                        score[0]++;
                        break;
                    case R.id.community:
                        score[0]++;
                        break;
                }
            }
        };

        // adds the variables together to form a score

        if(score[0] == 0){
            output.setText("Come on! Get involved, your la sallian community needs you.");
        } else if(score[0] == 1){
            output.setText("Good start, keep going!");
        } else if(score[0] == 2){
            output.setText("Room to improve but doing good!");
        } else if(score[0] == 3){
            output.setText("Very good, others look up to you!");
        } else if(score[0] == 4){
            output.setText("Wow, you really are an inspiration");
        } else if(score[0] == 5){
            output.setText("Excellent! You're a leader in your la sallian community. Nice work!");
        } else{
            output.setText("Unknown");
        }
        // changes the output text based on score value
    }
}

Answer 1

您正在定义一个已检查的侦听器，但不对其执行任何操作。您需要将其设置为复选框或复选框。

mCheckBox = (CheckBox) findViewById(R.id.concern);
mCheckBox.setOnCheckedChangedListener(checkedListener);

就像按钮一样。

为按钮设置事件
