在回复获得成功消息后，我想在各自的编辑文本字段中保存已编辑的详细信息，请帮助。成功消息后，我通过意图移动到主屏幕，然后我又回到此屏幕显示以前的详细信息。

您希望在从网络下载后或在编辑文本字段中进行编辑后保存数据吗？
如果来自网络，请在下载数据成功的代码中添加一些保存方法执行语句
if (json_status.equalsIgnoreCase("Success")){
Toast.makeText(getApplicationContext(), "changed parent details successfully", Toast.LENGTH_SHORT).show();
// here you have successful received data so u can map them to edit text or save in shared prefs
// add method to save data here
saveData(response);
startActivity(new Intent(getApplicationContext(),ActivityHome.class));
}
private void saveData(JSONObject response) {
// use JSon response object save here to shared preferences
// see how to load data from json object
// https://processing.org/reference/JSONObject_getString_.html
SharedPreferences sharedPreferences = getSharedPreferences(AppConstants.OOSH_PREFERENCES, Context.MODE_PRIVATE);
sharedPreferences.putString(....).apply;
// or set edit text controls with JSon data
}
要保存编辑文字更改，您有两个选择：
添加到布局保存按钮（您有一个）按钮并使用方法设置点击监听器以保存数据：
btnSave = (CustomButton) findViewById(R.id.btn_save_parent);
btnSave.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
saveData(v);
}
});
private void saveData(View view) {
// get root view
View rootView = view.getRootView();
// find edit text widget on root view
EditText etFirstName = (EditText) rootView.findViewById(R.id.edit_first_name);
// get string from edit text widget
String firstName = etFirstName.getString.toString();
// get shared preferences
SharedPreferences sharedPreferences = getSharedPreferences(AppConstants.OOSH_PREFERENCES, Context.MODE_PRIVATE);
// save to shared prefs firstName wher NAME_KEY is string to identified your saved data for later use - to load
sharedPreferences.putString(NAME_KEY,firstName).apply;
}
private void loadDataFromSharedPredferences(View view) {
// get shared preferences
SharedPreferences sharedPreferences = getSharedPreferences(AppConstants.OOSH_PREFERENCES, Context.MODE_PRIVATE);
// load data from shared prefs firstName wher NAME_KEY is string to identified data to load
String firstName = sharedPreferences.getString(NAME_KEY,firstName);
// get root view
View rootView = view.getRootView();
// find edit text widget on root view
EditText etFirstName = (EditText) rootView.findViewById(R.id.edit_first_name);
// set string to edit text widget
etFirstName.setText(firstName);
}
为edittext小部件添加文本更改侦听器
<强> PS。你需要澄清 - 写下你想要实现的目标的确切步骤

这一切都发生在这里：
...
if (json_status.equalsIgnoreCase("Success")){
Toast.makeText(getApplicationContext(), "changed parent details successfully", Toast.LENGTH_SHORT).show();
startActivity(new Intent(getApplicationContext(),ActivityHome.class));
}
...
成功回复后，将已编辑的值保存在首选项中，例如etFirstName，将其保存为相应首选项的新值：
...
if (json_status.equalsIgnoreCase("Success")){
Toast.makeText(getApplicationContext(), "changed parent details successfully", Toast.LENGTH_SHORT).show();
editor.putString(AppConstants.PARENT_FNAME, parentFirstName);
editor.apply(); //don't forget this
startActivity(new Intent(getApplicationContext(),ActivityHome.class));
}
...
您以任何方式创建编辑器但不使用它。
