android - 运行简单墙纸应用程序时出错

我对android编程很新颖。我试图通过创建一个简单的应用程序来设置墙纸背景来学习Android。我承认在android开发中有很多基本概念，我仍然不知道和理解，所以请对我好。android - 运行简单墙纸应用程序时出错

我使用Android SDK 4.1，Eclipse Indigo。

设置我的AVD规格：

CPU/ABI: ARM (armeabi-v7a) 
Target: Android 4.1 (API level 16) 
Skin: WVGA800 
SD Card: 512

我有一个错误，每次我运行应用程序。

错误：

你的问题说得清楚吗，请清楚说明吧 – Ramkumar 2012-08-11 06:55:04

刚刚更新了我的问题。我每次尝试运行应用程序时总会遇到错误。 – AndroidMoron 2012-08-11 07:00:45

尝试改变你的java文件到这里，看看它是如何工作的。不知道这是否正是你想要的，但我认为它应该可以帮助你一点。

package com.example.androidwallpaper; 

import android.os.Bundle; 
import android.app.Activity; 
import android.app.AlertDialog; 
import android.view.Menu; 
import android.view.View; 

public class MainActivity extends Activity { 

    AlertDialog.Builder builder; 

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

     builder = new AlertDialog.Builder(this); 
     builder.setTitle("Codes"); 
     builder.setMessage("Put codes here later!"); 
     builder.show(); 
    } 
    /* 
    public void setWallPaper (View view) { 
     new AlertDialog.Builder(this).setTitle("Codes").setMessage("Put codes here later!"). 
     setNeutralButton("Close", null).show(); 
    }*/ 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     getMenuInflater().inflate(R.menu.activity_main, menu); 
     return true; 
    } 
}

你也应该可以说所有的builder.setNeutralButton()

问题不在于按钮功能。其实应用程序甚至没有启动。单击运行后 - > Android应用程序后，我收到错误。 – AndroidMoron 2012-08-11 07:14:45

它看起来像一个运行时错误 - 比编译时错误更难以捕捉;当我得到运行时错误时，清理一下我的代码，或者改变它通常都有帮助。有时甚至有助于简单地重启AVD。但是这就是为什么我建议改变它，只是为了测试，只是为了看看它是否真正以这种方式切换它的方式。 – corecase 2012-08-11 07:18:27

我实际上创建了一个新的AVD，并尝试在那里运行它，但仍然有相同的错误。我不知道这是否与内存不足问题有关，我只是猜测。 – AndroidMoron 2012-08-11 07:21:25

首先请参阅你是给了壁纸的正确道路进行设置。

2.如果你是新的Android或任何编程语言或框架，然后分解成东西部分，当你把所有的功能部件，然后把它们放在一起......

您已经使用警告对话框，菜单等......但是你有没有尝试将墙纸放在第一位，在这种情况下是你的主要目标。

编写程序时，无论是微小或巨大的你应该申请OOAD原则....

下面是两行代码申请墙纸，尝试了这一点..然后尝试围绕它建设

WallpaperManager wpm = WallpaperManager.getInstance(Your_Activity.this); 
wpm.setBitmap(bit_map_name);
