java - 如何设置从另一个 Activity 检查的单选按钮？

Question

我有两项 Activity 。第一个 Activity 具有不同的布局，可打开另一个 Activity 。在另一个 Activity 中，我有一组分段的单选按钮，我想根据在第一个 Activity 中单击的布局将其设置为选中。为了检查单选按钮，我使用了这个。

segmented5.check(R.id.pickupbakButton);

这将按钮设置为选中，但我希望从另一个 Activity 中检查它，因为我在布局中进行了其他更改。

我有第一个这样的 Activity :

我们可以说 PICKUPBOX/BLIND VAN 的 onClick

它应该显示选中的皮卡/盲车单选按钮。

我怎样才能实现这个目标？

GoBoxActivity

public class GoBoxActivity extends AppCompatActivity {

private Intent i;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_go_box);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    toolbar.setTitle("GO-BOX");
    setSupportActionBar(toolbar);

    toolbar.setNavigationIcon(R.drawable.ic_arrow_back_white_24dp);

    toolbar.setNavigationOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            onBackPressed();
        }
    });

   final GoBoxPickupActivity gobox = new GoBoxPickupActivity();

   LinearLayout pickupBak = (LinearLayout)findViewById(R.id.PickupBak);
    LinearLayout picupBox = (LinearLayout)findViewById(R.id.pickupbox);
    LinearLayout engkelBak = (LinearLayout)findViewById(R.id.engkelBak);
    LinearLayout engkelBox = (LinearLayout)findViewById(R.id.engkelBox);

    pickupBak.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            i=new Intent(getApplicationContext(),GoBoxPickupActivity.class);
            startActivity(i);
        }
    });

    picupBox.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            i=new Intent(getApplicationContext(),GoBoxPickupActivity.class);
            startActivity(i);
        }
    });

    engkelBak.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            i=new Intent(getApplicationContext(),GoBoxPickupActivity.class);
            startActivity(i);
        }
    });
    engkelBox.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            i=new Intent(getApplicationContext(),GoBoxPickupActivity.class);
            startActivity(i);
        }
    });
  }
}

PickupBoxActivity

     @Override

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
segmented5 = (SegmentedGroup) findViewById(R.id.segmented3);

    segmented5.setOnCheckedChangeListener(this);

 @Override
    public void onCheckedChanged(RadioGroup group, int checkedId) {
        switch (checkedId) {
            case R.id.pickupbakButton:

                engkelTextview.setVisibility(View.GONE);
                extraEngkelTextView.setVisibility(View.GONE);
                airConditioning.setVisibility(View.GONE);
                picBoxTextview.setVisibility(View.VISIBLE);
                extraPickBoxTextview.setVisibility(View.VISIBLE);

                return;

            case R.id.pickupboxButton:

                engkelTextview.setVisibility(View.GONE);
                extraEngkelTextView.setVisibility(View.GONE);
                airConditioning.setVisibility(View.VISIBLE);
                picBoxTextview.setVisibility(View.VISIBLE);
                extraPickBoxTextview.setVisibility(View.VISIBLE);

                extraPickBoxTextview.setVisibility(View.GONE);
                engkelTextview.setVisibility(View.VISIBLE);
                extraEngkelTextView.setVisibility(View.VISIBLE);

                return;
            default:

                extraEngkelTextView.setVisibility(View.GONE);
                airConditioning.setVisibility(View.GONE);
                picBoxTextview.setVisibility(View.VISIBLE);
                extraPickBoxTextview.setVisibility(View.VISIBLE);
        }
    }
}

修改GoBoxActivity中onClick内的代码，如下

i=new Intent(getApplicationContext(),GoBoxPickupActivity.class);
i.putExtra("selected", 1);
startActivity(i);

在 PickupBoxActivity 中，执行类似的操作

int selected = getIntent().getIntExtra("selected",1);

之后

switch(selected)
{
    case 1:
      segmented5.check(R.id.pickupbakButton);
    break;
    case 2:
       .... So on
}
