KSOAP を使用した Web サービスを使用して、データベースに保存する詳細を送信しています。正常に動作する Web サービスに問題はありません。このコードは、AsyncTask クラスを使用していないときに機能しました。私はアンドロイドが初めてで、AsyncTask クラスを使用しようとしたのはこれが初めてで、機能しません。ログ cat エラーを添付しました。doinbackround メソッドに何か問題があります。私は何を間違っていますか？助けてください

を使用して文字列を比較しないでください==。

protected void onPostExecute(String result) {
        if(result=="Registered")

これが、予期しない動作の背後にある理由である可能性があります。次のようなものを使用してみてください

result.equals("registered")

これを試して....

  1. 常に UI 作業を UI スレッドに保持し、非 UI 作業を非 UI スレッドに保持します。

  2. doInBackground は非 UI スレッドであるため、これから UI スレッドに投稿することはできません。

  3. Toast ステートメントは doInBackgroud の問題です。UI スレッドで動作している postExecute に移動します。

    Toast.makeText(Registration.this, "You have been registered Successfully", Toast.LENGTH_LONG).show();

あなたが呼んでいる

Toast.makeText(Registration.this, "You have been registered Successfully", Toast.LENGTH_LONG).show();

UIスレッドで実行されていないdoInBackground（）内。それが問題の原因です。

これを試して：

runOnUiThread(new Runnable() {
    public void run() {
         Toast.makeText(Registration.this, "You have been registered Successfully", Toast.LENGTH_LONG).show();
    }
});
}

またはToast.makeText、UI スレッドで実行される onPostExecute() メソッドに移動します。

これは、doInBackground() で Toast を呼び出しているためです。doInBackground のどの UI でも looper() 例外が発生します。AsynTask の PostExecute() で UI を次のように作成してみてください。

@Override
protected void onPostExecute(String result) {

 Toast.makeText(Registration.this, "You have been registered Successfully",Toast.LENGTH_LONG).show();

}
 }

それはあなたに役立つかもしれません..
