如何Android中在第二按钮中的第一个和数据（INT）数据（int）的比较？ [英] How to compare data(int) in the first and data(int) in second button in Android?

问题描述

我有我想要做比较的问题按钮，在数据

I have a problem where I want to make the comparison the data in button

package lynn.calculate.KaunterKalori;

import lynn.calculate.KaunterKalori.R;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.TextView;
import android.widget.EditText;

public class CalculateAll extends Activity implements OnClickListener {


protected int totalKalori1;
protected int totalKalori2;
protected int totalKalori3;

EditText EstimateCalorie;
TextView TotalKaloriSehari;
TextView totalsarapan;
TextView totallunch;
TextView totaldinner;
TextView calorieneeds;
TextView resultDiff;

public CalculateAll() {

}

@Override
public void onCreate(Bundle savedInstancesState) {
    super.onCreate(savedInstancesState);
    setContentView(R.layout.calculate_all);

    View kiraButton = findViewById(R.id.buttonKiraAll);
    kiraButton.setOnClickListener(this);

    View bezaButton = findViewById(R.id.caloriediff);
    bezaButton.setOnClickListener(this);

    TotalKaloriSehari = (TextView) findViewById(R.id.JumlahKalori);
    totalsarapan = (TextView) findViewById(R.id.sarapantext);
    totallunch = (TextView) findViewById(R.id.lunchtext);
    totaldinner = (TextView) findViewById(R.id.dinnertext);
    EstimateCalorie = (EditText) findViewById(R.id.BMR);
    // calorieneeds = (TextView) findViewById(R.id.BMR);
    resultDiff = (TextView) findViewById(R.id.result);

    Bundle extras = getIntent().getExtras();
    if (extras != null) {
        totalKalori1 = extras.getInt("totalBreakfast");
        totalKalori2 = extras.getInt("totalLunch");
        totalKalori3 = extras.getInt("totalDinner");
    }

    totalsarapan.setText(totalKalori1 + "");
    totallunch.setText(totalKalori2 + "");
    totaldinner.setText(totalKalori3 + "");



}

public void onClick(View v) {
    if (v.getId() == R.id.buttonKiraAll) {


     int TotalKalori = calculateTotalKalori(totalKalori1, totalKalori2,
                totalKalori3);
        TotalKaloriSehari.setText(TotalKalori + "");

    }

    else if (v.getId()== R.id.caloriediff) {

        int nilaikalori = Integer.parseInt(EstimateCalorie.getText()
                .toString());


        int bmr = calculatebmr(nilaikalori);

        String deskripsiKalori = describekalori(bmr);
        resultDiff.setText("kalori makanan" + TotalKalori + " calori  diperlukan " + bmr + "=" + deskripsiKalori); 
// --> this TotalKalori also can't be used


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

    }

}




public int calculateTotalKalori(int totalKalori1, int totalKalori2,
        int totalKalori3) {
    return (int) (totalKalori1 + totalKalori2 + totalKalori3);

}

public int calculatebmr(int nilaikalori) {
    return (int) (nilaikalori);
}

private String describekalori(int bmr) { 

    if (bmr < TotalKalori ) { //<-- this TotalKalori can't be read/used
        return "bykkan makan";
    } else if (bmr == TotalKalori) {

        return "kekalkan jumlah kalori ini";

    } else if (bmr > TotalKalori) {

        return "kurangkan pengambilan kalori";

    } else
        return "oiii";

} 
}

第一个按钮，buttonKiraAll阅读INT totalKalori，然后我想用与第二数据按钮calorieDiff进行比较totalKalori数据，我多么想使totalKalori可以通过第二个按钮读取？这样我就可以作出比较

The first button, buttonKiraAll read int totalKalori, then i want to use the totalKalori data to be compare with 2nd data button calorieDiff, how i want to make the totalKalori can be read by the second button? so i can make the comparison

推荐答案

声明的 INT TotalKalori 只有一次全球性（你声明的部分保护INT totalKalori1;保护INT totalKalori2; ... ），并简单地使用它像两个按钮：在Button1的TotalKalori = calculateTotalKalori（totalKalori1，totalKalori2，totalKalori3）;这个值是全球化，所以按钮2已经可以简单地使用TotalKalori你需要，也是比较的部分。

Declare int TotalKalori only once globally (in the section you declared protected int totalKalori1; protected int totalKalori2;... ) and simply use it for both buttons like: in button1 TotalKalori = calculateTotalKalori(totalKalori1, totalKalori2,totalKalori3); this value is global so button2 already can acess it by simply using TotalKalori where you need and also the comparison portion.
