将参数与R.id. [attribute]捆绑在一起

问题描述

我试图将整数从7个不同的片段发送到第8个片段，该片段将被发送到SQLite数据库。 不过目前，我什么也无法发送到另一个片段。

MiscTab.java

package com.example.test.test;

import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.TextView;




public class MiscTab extends Fragment {
    private static final String TAG = "MiscTab";
    private View root;

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup @Nullable Bundle savedInstanceState) {
        // Find the root view, and put in into a variable for later use by other functions
        this.root = inflater.inflate(R.layout.misc_tab, container, false); //creates this.setupButton(R.id.misc_dead_bot_int, R.id.misc_dead_bot_plus, 0, 1, 1);
        this.setupButton(R.id.misc_dead_bot_int, R.id.misc_dead_bot_minus, 0, 1, -1);
        this.setupButton(R.id.misc_disabled_bot_int, R.id.misc_disabled_bot_plus, 0, 1, 1);
        this.setupButton(R.id.misc_disabled_bot_int, R.id.misc_disabled_bot_minus, 0, 1, -1);
        this.setupButton(R.id.misc_tipped_bot_int, R.id.misc_tipped_bot_plus, 0, 1, 1);
        this.setupButton(R.id.misc_tipped_bot_int, R.id.misc_tipped_bot_minus, 0, 1, -1);
        this.setupButton(R.id.misc_didnt_show_int, R.id.misc_didnt_show_plus, 0, 1, 1);
        this.setupButton(R.id.misc_didnt_show_int, R.id.misc_didnt_show_minus, 0, 1, -1);
        return this.root;
    }

    private void setupButton(int textID, int buttonID, final int minimum, final int maximum, final int stepValue) {
        // Find the button from the view
        Button button = this.root.findViewById(
        // Find the buttons textview from the view
        final TextView text = this.root.findViewById(
        // Set the buttons actions to increase the count by the step value
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View 
                // Find the text views current value. If there is an error, assume 0
                int initialCount;
                try {
                    initialCount = Integer.parseInt(text.getText().toString());
                } catch (Exception e) {
                    e.printStackTrace();
                    initialCount = 0;
                }
                // Calculate the final count value
                int finalCount = initialCount + stepValue;
                // Check if it matches the bounds
                if (finalCount > maximum) {
                    finalCount = maximum;
                }
                if (finalCount < minimum) {
                    finalCount = minimum;
                }
                // Update the text to display the new final count
                text.setText(String.valueOf(finalCount));
            }
        });

    }
}

我的MainActivity.java中的相关代码

Bundle arguments = new Bundle();
arguments.putInt(MiscTab.misc_dead_bot_int);

当我尝试将MiscTab.misc_dead_bot_int传递给MiscTab.misc_dead_bot_int的参数时，它告诉我无法解决它。 我认为这是因为它没有在任何地方初始化，而是仅跟随XML中的字符串。 我不确定如何将这些值转换为可发送格式。 我尝试将其发送到字符串，但是我得到的唯一输出值却是一个大数字。
