Android应用程序意外崩溃

我遇到问题，我的应用程序意外停止。这是一个简单的应用程序，让用户输入骰子数和过滤器编号。它意外崩溃，即使我多次清理它。这里是java文件：Android应用程序意外崩溃

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; 
} 
}

这里是错误日志：

您的应用程序正在试图寻找一个可绘制名为'＃000000'。这是黑色的颜色，不是可绘制的。我觉得你已经把它放在你的XML的某个地方，它不属于它。 – Eric

logcat告诉你这是你的布局XML文件中的错误，在＃2行。请张贴该文件，以便我们提供帮助。 – Huang

是的。这是我的XML的背景颜色。 –

我怀疑你的问题是在XML文件中，在这里：

android:background="@string/backgroundcolor"

你在做什么这里传递一个字符串，应该采取一种颜色或绘制参考的字段。据我所知，如果有问题的字符串是有效的颜色字符串（如＃012），则无关紧要。这不会像预处理宏那样被替换为文本，而是会在运行时查找它，并获得它不期望的值。

为了解决这个问题，从

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

的定义修改为

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

，并指它在布局文件

android:background="@color/backgroundcolor"

非常感谢解决方案。但是，我使用＃000000而不是字符串，它的工作。 –

哎呀我实际上混淆了我所说的，意思是说从字符串到颜色的变化，而不是相反（现在将编辑）：P很高兴我能帮忙，虽然:) – Xono

谢谢。希望别人能看到它并修正它们的程序：D –

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); 
    } 
};

你是指两个EditText上相同的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); 
}

};
