我的应用程序意外停止时遇到问题。这是一个简单的应用程序，让用户输入骰子数和过滤器数。即使我多次清洁它，它也会意外崩溃。这是java文件：

package com.greg.rostov.dice;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

public class DiceRoller extends Activity {
DiceRoller r=new DiceRoller();

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

    Button roll=(Button)findViewById(R.id.roll);

    roll.setOnClickListener(onRoll);
}
private View.OnClickListener onRoll=new View.OnClickListener() {
        public void onClick(View v){
            EditText numberofdice=(EditText)findViewById(R.id.roll);
            EditText filterdice=(EditText)findViewById(R.id.roll);
        }
    };




private String numberofdice="";
private String filterdice="";

public String getNumberofdice() {
    return(numberofdice);
}
public void setNumberofdice(String numberofdice){
    this.numberofdice=numberofdice;
}

public String getFilterdice() {
    return(filterdice);
}
public void setFilterdice(String filterdice){
    this.filterdice=filterdice;
}
}

这是错误日志：

看看你的听众：

private View.OnClickListener onRoll=new View.OnClickListener() {
    public void onClick(View v){
        EditText numberofdice=(EditText)findViewById(R.id.roll);
        EditText filterdice=(EditText)findViewById(R.id.roll);
    }
};

您为 EditText 引用相同的 ID：numberofdice 和 filterdice。

将其更改为：

private View.OnClickListener onRoll=new View.OnClickListener() {
public void onClick(View v){
    EditText numberofdice=(EditText)findViewById(R.id.dicebox);
    EditText filterdice=(EditText)findViewById(R.id.filterdicebox);
}

};

我怀疑你的问题出在你的 XML 文件中，这里：

android:background="@string/backgroundcolor"

您在这里所做的是将字符串传递给应该采用颜色或可绘制参考的字段。据我所知，所讨论的字符串是否是有效的颜色字符串（如#012）并不重要。这不会被视为替换文本的预处理器宏，而是会在运行时查找它并获得它不期望的值。

要修复它，请将定义从

<string name="backgroundcolor">#000000</string>

到

<color name="backgroundcolor">#000000</color>

并在您的布局文件中将其引用为

android:background="@color/backgroundcolor"
