我在sqlite中使用edittext插入值并在listview中显示...之后我点击listview中的单行并且单行值再次显示在之前的edittext中..现在我想更新此edittext来自listview的价值。请有人告诉我怎么做？
< Intent intent = getIntent（）;
name = intent.getStringExtra（Name）;
desg = intent.getStringExtra（Designation）;
nam =（EditText）findViewById（R.id.NameEditText）;
des =（EditText）findViewById（R.id.desgEditText）;
nam.setText（name）;
des.setText（desg）;
insertButton.setOnClickListener（new View.OnClickListener（）{
@Override
public void onClick（View v）{
String employeename = nameEditText.getText（）。toString（）;
int employeeno = Integer.parseInt（noEditText.getText（）。toString（））;
字符串指定= desgEditText.getText（）。toString（）;
dbhelper.insertIntoEmployeeTable（employeename，designation，employeeno）;
Log .V（E mp_Name，employeename）;
Log.v（Emp_no，String.valueOf（employeeno））;
Log.v（Emp_Desg，名称）;
Toast.makeText（getBaseContext（），你的数据被插入，Toast.LENGTH_SHORT）.show（）;
}
}）;
updateButton.setOnClickListener（new View.OnClickListener（）{
@Override
public void onClick（View v）{
String employeename = nam.getText（）。toString（）;
int employeeno = Integer.parseInt（noEditText.getText（）。toString（））;
字符串指定= des.getText（）。toString（）;

}）;
displayButton.setOnClickListener（new View.OnClickListener（）{
@Override
public void onClick（View v）{
Intent i = new Intent（MainActivity.this，GridViewActivity.class）;
