感谢您的帮助

只需传递在您的“意图到家”活动中按下的按钮，并在您的“意图到家”活动中从“意图”获取数据，然后使用“如果”条件应用您的按钮禁用

因此，如果您的家庭活动仅由选择活动打开，则可以使用意图传递此数据，否则可以使用SharedReference保存数据，然后在家庭活动中检索此首选项

要通过intent传递数据和检索数据，请参阅此处-

要通过共享首选项存储和检索，请参阅此处-

当按下雇主按钮时，通过意图传递
false
值。

使用
setEnabled（false）
从
onClickListener

如果您想更方便地了解按钮是否被选中/按下，您可以使用按钮的
setSelected（true）
（或false）功能，以便随时询问按钮是否被选中

希望有帮助：）

使用
setEnabled（false）
在
onClickListener中禁用您想要禁用的按钮

如果您不需要传递
意图
就可以通过注册到
OnSharedPreferenceChangeListener
来实现此行为。下面是一个例子：

HomeActivity.java:


Intent i = new Intent(Selection.this, HomeActivity.class);
intent.putExtra("IS_EMPLOYEE", true);
startActivity(i);



if(getIntent().getExtras().getBoolean("IS_EMPLOYEE")){
    // do what you want to do on employee button press.
}
else{
    // do what you want to do on employer button press.
}



public class HomeActivity extends AppCompatActivity implements View.OnClickListener, 
SharedPreferences.OnSharedPreferenceChangeListener{

    public static final String BTN_EMPLOYEE_PREFS_TAG = "employeeTag";
    private ImageButton addEmployee;
    private ImageButton generateReport;
    private SharedPreferences prefs;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_home);
        addEmployee = (ImageButton) findViewById(R.id.addEmployee);
        generateReport = (ImageButton) findViewById(R.id.generateReport);
        .
        .
        .
        prefs = PreferenceManager.getDefaultSharedPreferences(this);
        prefs.registerOnSharedPreferenceChangeListener(this);
        .
        .
        .
     }


    @Override
    public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {

        if(BTN_EMPLOYEE_PREFS_TAG.equals(key)){
        // listens to any changes made on this tag
            boolean enableOrDisable = prefs.getBoolean(BTN_EMPLOYEE_PREFS_TAG, false);
            addEmployee.setEnabled(enableOrDisable);
            generateReport.setEnabled(enableOrDisable);
        }
    }
