Android Studio - 如何保存按钮值？

Question

我喜欢在使用按钮后保存和禁用按钮（下面的代码行）：

btn1.setEnabled(false);

我已经知道我必须使用 SharedPreferences，但我仍然需要代码方面的帮助。我已经尝试了很多但没有成功。那是我的代码。

public class Pass extends AppCompatActivity implements View.OnClickListener {

private Button btn1;
private EditText text1;


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

    btn1 = (Button) findViewById(R.id.button);
    btn1.setOnClickListener(this);

    text1 = (EditText) findViewById(R.id.editText);
    text1.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);



}


public void onClick (View view){


    if (text1.getText().toString().equals("Pass)){
        AlertDialog ad = new AlertDialog.Builder(this).create();
        ad.setMessage("Super");
        ad.show();
        Intent intent = new Intent(this,Popup.class);
        startActivity(intent);

        btn1.setEnabled(false);

    }else{
        String message = "Leider falsch";
        Toast.makeText(this,message, Toast.LENGTH_LONG).show();
    }
}

}

感谢您的帮助

public class Pass extends AppCompatActivity implements View.OnClickListener 
{

private Button btn1;
private EditText text1;
private SharedPreferences sharefPref;
private SharedPreferences.Editor editor;

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

btn1 = (Button) findViewById(R.id.button);
btn1.setOnClickListener(this);

text1 = (EditText) findViewById(R.id.editText);
text1.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD);
sharedPref = getActivity().getPreferences(Context.MODE_PRIVATE);
editor = sharedPref.edit();
}


public void onClick (View view){

if(sharedPref.getBoolean("YourKey"),true)
{
editor.putBoolean("YourKey",false);
editor.commit();

if (text1.getText().toString().equals("Pass)){
    AlertDialog ad = new AlertDialog.Builder(this).create();
    ad.setMessage("Super");
    ad.show();
    Intent intent = new Intent(this,Popup.class);
    startActivity(intent);

}else{
    String message = "Leider falsch";
    Toast.makeText(this,message, Toast.LENGTH_LONG).show();
}

}
}
