以下のようにスレッドメソッドでListViewを変更したため、上記のエラーが発生しましたが、致命的なエラーの部分です。
private Runnable ChkSuggestionListConn = new Runnable(){
@Override
public void run() {
try{
... here is get my http link connection
}(Exception e){
Log.e("log_tag", "Error converting result "+e.toString());
}
try{
... here is get my http result and put it into array
}(Exception e){
listView.setVisibility(View.GONE);
//so the problem at here
}
ここで、ハンドルメソッドで解決した私の解決策を示します
public void handleMessage(Message msg) {
super.handleMessage(msg);
if(msg.what == EMPTY_RESULT){
System.out.println("handleMsg EMPTY_RESULT");
listView.setVisibility(View.GONE);
}
}
};
//note that handle method is do at the above OnCreate
private Runnable ChkSuggestionListConn = new Runnable(){
@Override
public void run() {
try{
... here is get my http link connection
}(Exception e){
Log.e("log_tag", "Error converting result "+e.toString());
}
try{
... here is get my http result and put it into array
}(Exception e){
messageHandler.sendEmptyMessage(EMPTY_RESULT);
}
