voici mon code java (enfin le tien) :
package com.example.montestparametre;
import androidx.appcompat.app.AppCompatActivity;
import android.content.Context;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.preference.PreferenceManager;
import android.view.View;
import android.widget.EditText;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
public String txt1, txt2;
public EditText string1, string2;
public SharedPreferences sharedpreferences ;
public final static String TXT1="", TXT2="";
public static final String filepref = "filepref";
@override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
string1 = (EditText) findViewById(R.id.editText1);
string2 = (EditText) findViewById(R.id.editText2);
sharedpreferences = getSharedPreferences(filepref, Context.MODE_PRIVATE);
}
public void sauvegarde_txt(View v) {
String s1 = string1.getText().toString();
String s2 = string2.getText().toString();
SharedPreferences.Editor editor = sharedpreferences.edit();
editor.putString(TXT1, s1);
editor.putString(TXT2, s2);
editor.commit();
}
public void recuperation_txt(View v) {
string1 = (EditText) findViewById(R.id.editText1);
string2 = (EditText) findViewById(R.id.editText2);
sharedpreferences = getSharedPreferences(filepref, Context.MODE_PRIVATE);
if (sharedpreferences.contains(TXT1)) {
string1.setText(sharedpreferences.getString(TXT1, ""));
}
if (sharedpreferences.contains(TXT2)) {
string2.setText(sharedpreferences.getString(TXT2, ""));
}
}
}
