试图显示一个列表视图

Question

我是新来的Android，我试图显示一个ListView，但每次我启动我的应用程序停止。我一直试图找出几个小时我的问题，但我没有发现什么是错的。提前感谢任何能够向我解释问题的人。这是我的main_activity类：

public TextView textView; 
public int count = 0; 
public ListView listView; 
public Context context; 
public List<HashMap<String,String>> list = new ArrayList<>(); 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    setContentView(R.layout.activity_main); 
    context = getApplicationContext(); 

    textView = (TextView)findViewById(R.id.text); 
    listView = (ListView)findViewById(R.id.listView); 

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

    button.setOnClickListener(new OnClickListener(){ 
     public void onClick(View v){ 
      count++; 
      addLine(count); 
      textView.setText(String.valueOf(count)); 
     } 
    }); 
} 

void addLine(int counter){ 
    if(counter>0){ 
    HashMap<String,String> hashMap = new HashMap<String,String>(); 
    for(int i=0;i < counter;i++){ 
     hashMap.clear(); 
     hashMap.put(String.valueOf(i),"test" + String.valueOf(i)); 
     list.add(hashMap); 
    } 
    String[] from = {"first","second"}; 
    int[] to = {android.R.layout.simple_list_item_1, android.R.layout.simple_list_item_2 }; 
    SimpleAdapter simpleAdapter = new SimpleAdapter(context,list,R.id.listView, from, to); 

    listView.setAdapter(simpleAdapter); 
    } 
} 

activity_main.xml中和我的logcat：

<?xml version="1.0" encoding="utf-8"?> 

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
     android:id="@+id/myLayout" 
     android:orientation="vertical" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent" 
     android:padding="8dp"> 

    <Button android:id="@+id/button" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_weight="10" 
     android:text="@string/buttonName" /> 

    <TextView 
     android:id="@+id/text" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_weight="20" 
     android:text="test"/> 


    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
     android:orientation="vertical" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_weight="70" 
     android:padding="8dp" > 

     <ListView 
      android:id="@+id/listView" 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      android:layout_weight="10" /> 

    </LinearLayout> 


</LinearLayout>

你to阵列必须具备的意见IDS在项目视图布局内绑定（通常他们是android.R.id.text1和android.R.id.text2如果您正在使用来自Android资源的简单项目布局），而不是其他一些布局ID。
