android-edittext - PLZ帮忙！如何让应用程序保存用户在edittext中写的内容？

Question

如图所示，我想将用户写的内容保存为便笺。因此，当用户重新打开应用程序时，他写的笔记将保留在日历下，顺便说一句，我使用了 EditText Multiline

package com.example.test;

import androidx.appcompat.app.AppCompatActivity;

import android.content.SharedPreferences;
import android.os.Bundle;
import android.widget.EditText;

public class MainActivity extends AppCompatActivity {

    private EditText editText;
    SharedPreferences sharedPreferences;

    private static final String SHARED_PREF_NAME= "mypref";
    private static final String KEY_NAME = "name";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        editText=findViewById(R.id.editTextTextMultiLine);

        sharedPreferences=getSharedPreferences(SHARED_PREF_NAME ,MODE_PRIVATE);

        String name = sharedPreferences.getString(KEY_NAME,null);


        SharedPreferences.Editor editor = sharedPreferences.edit();
        editor.putString(KEY_NAME, editText.getText().toString());
        editor.apply();
        editor.clear();
        editor.commit();
}
}

我认为你应该移到editor.clear()下面editor.commit()
