     if (equipment != null){ 

      desc.setText(String.valueOf(equipment.get_description())); 
      details.setText(String.valueOf(equipment.get_details()));

      desc.setVisibility(View.VISIBLE); 
      details.setVisibility(View.VISIBLE); 
      responsibility.setVisibility(View.VISIBLE); 
      btnupdate.setVisibility(View.VISIBLE); 
     }else { 
      Toast.makeText(Search_Equipments.this,"Not Found",Toast.LENGTH_LONG).show(); 
     } 
    } 

}

有人可以幫助我的代碼。如果通過了數據成功更新的條件，但是當我顯示來自數據庫數據的更新數據沒有更新時，有人可以幫我解決這個問題。。。。。。因爲我不在那裏是我的錯誤。看我的更新代碼。謝謝:)不能更新sqlite數據庫中的數據

這個equipment_id名稱是否與您的表列名稱相同？ –

post ur table schema too ..... –

query =「CREATE TABLE IF NOT EXISTS tbl_equipments（equipment_id TEXT，description TEXT，details TEXT，responsibility_center TEXT，status TEXT，date_taken DATETIME）」; – mics

你忘了提交交易。

database.setTransactionSuccessful(); 
database.endTransaction();
