推荐答案

以下链接 Android SQLite

您必须将值存储在数组列表中，并从数据库检索，并将值设置为编辑文本

You have to store the value in an arraylist and which is retrieved from database and set the value to the edit text as

// myarraylist is the arraylist which contains 
// the data retrieved from database
editText.setText(myarraylist.get(0)); 

检索数据后，必须检查 editText的条件。 getText（）。toString（）长度大于零，您不应允许他们使用以下

After the data is retrieved, you have to check the condition whether editText.getText().toString() length is greater then zero you should not allow them to edit the text in editText by using following

  editText.setFocusable(false);
