Android Studio中选中的SharedPreferences Save复选框

Question

我尝试遵循此示例Shared Preferences Example 在此示例中创建2复选框。我尝试了不同的方法，但是没有保存任何更改。如果只是单击复选框并保留最后一个选择的值，我只是不希望其安全。我是Java的新手，希望有人可以向我解释如何通过此示例解决此问题。

package example.com.max.lschennn;

import android.app.Activity;
import android.content.Context;
import android.content.SharedPreferences;
import android.os.Bundle;
import android.view.View;
import android.widget.CheckBox;
import android.widget.TextView;

public class MainActivity extends Activity {
SharedPreferences sharedpreferences;
TextView name;
TextView email;
CheckBox check1;
CheckBox check2;

public static final String mypreference = "mypref";
public static final String Name = "name";
public static final String Email = "email";
public static final String CHECK1 = "check1";
public static final String CHECK2 = "check2";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    name = (TextView) findViewById(R.id.etName);
    email = (TextView) findViewById(R.id.etEmail);
    check1 = (CheckBox) findViewById(R.id.checkBox1);
    check2 = (CheckBox) findViewById(R.id.checkBox2);
    sharedpreferences = getSharedPreferences(mypreference,
            Context.MODE_PRIVATE);
    if (sharedpreferences.contains(Name)) {
        name.setText(sharedpreferences.getString(Name, ""));
    }
    if (sharedpreferences.contains(Email)) {
        email.setText(sharedpreferences.getString(Email, ""));

    }

}

public void Save(View view) {
    String n = name.getText().toString();
    String e = email.getText().toString();
    SharedPreferences.Editor editor = sharedpreferences.edit();
    editor.putString(Name, n);
    editor.putString(Email, e);
    editor.putBoolean(String.valueOf(check1), true); // Storing boolean - true/false
    editor.putBoolean(String.valueOf(check2), true); // Storing boolean - true/false
    editor.commit();
}

public void clear(View view) {
    name = (TextView) findViewById(R.id.etName);
    email = (TextView) findViewById(R.id.etEmail);
    name.setText("");
    email.setText("");

}

public void Get(View view) {
    name = (TextView) findViewById(R.id.etName);
    email = (TextView) findViewById(R.id.etEmail);

    sharedpreferences = getSharedPreferences(mypreference,
            Context.MODE_PRIVATE);

    if (sharedpreferences.contains(Name)) {
        name.setText(sharedpreferences.getString(Name, ""));
    }
    if (sharedpreferences.contains(Email)) {
        email.setText(sharedpreferences.getString(Email, ""));

    }
}

}
