私はAndroidには新しく、リストビューを表示しようとしていますが、アプリケーションを起動するたびに停止します。私は何時間も私の問題を理解しようとしてきましたが、何が間違っているのか分かりません。問題が何であるか私に説明することができるかもしれない誰かに事前に感謝します。ここに私のmain_activityクラスです：リストビューを表示しようとしています
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と私のlogcat：

アプリがクラッシュしていることを「停止」した場合、LogCatを使用してクラッシュに関連するJavaスタックトレースを調べます。https://stackoverflow.com/questions/23353173/unfortunately-myapp-has-stopped-how -can-i-solve-this – CommonsWare
これは私がやったことです、私は私のポストにlogcatコンテンツを与えます。しかし、私はまだ問題をターゲットにすることはできません – masterbate
