我在名为“选择”的活动中有两个按钮“雇员”和“雇主”，如果按下“雇员”按钮，则应禁用“主页”活动中的两个按钮“addEmployee”和“generateReport”。

选拔活动

public class Selection extends AppCompatActivity {

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

    final Button btn_Employee = (Button) findViewById(R.id.btn_Employee);
    Button btn_Employer = (Button) findViewById(R.id.btn_Employer);

    btn_Employee.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View vEmployee) {
            if(btn_Employee.isPressed())
            {
                //markAttendance and generateReport button should be disabled

                Intent i = new Intent(Selection.this, HomeActivity.class);
                             startActivity(i);
            }

    }
    });

    btn_Employer.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View vEmployer) {

        }
    });
}
}

家庭活动

public class HomeActivity extends AppCompatActivity implements View.OnClickListener {

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

    ImageButton markAttendance = (ImageButton) findViewById(R.id.markAttendance);
    ImageButton viewHolidays = (ImageButton) findViewById(R.id.viewHolidays);
    ImageButton addEmployee = (ImageButton) findViewById(R.id.addEmployee);
    ImageButton generateReport = (ImageButton) findViewById(R.id.generateReport);

    Toolbar toolbar = (Toolbar) findViewById(R.id.sign_in_toolbar);
    setSupportActionBar(toolbar);
    getSupportActionBar().setTitle(getTitle());

    markAttendance.setOnClickListener(this);
    viewHolidays.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            holidays();
        }
    });
  addEmployee.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
            AddEmployee();
      }
  });
   generateReport.setOnClickListener(new View.OnClickListener() {
       @Override
       public void onClick(View v) {
           report();
       }
   });
}

private void AddEmployee() {
    Intent addIntent =  new Intent(this, EmployeeDetails.class);
    startActivity(addIntent);
}

private void report() {
    Intent webIntent = new Intent(this, TempWeb.class);
    startActivity(webIntent);
}

private void holidays() {
Intent holidayIntent = new Intent(this, Holiday.class);
    startActivity(holidayIntent);
}

@Override
public void onClick(View v) {
    attendance();
}

private void attendance() {
    Intent attendanceIntent = new Intent(this, MarkAttendance.class);
    startActivity(attendanceIntent);
}
}

您可以通过通过您的 Intent 传递一些数据来实现，这些数据可以识别在中Home Acitivity，按下了哪个按钮Selection Activity。

在按下员工按钮的选择活动中：

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

在 Home Activity 中检查是否按下了员工按钮，并执行相应的操作：

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.
}

false当Selection Activity，雇主按钮被按下时，也通过意图传递值。
