如何设置从其他活动中选中的单选按钮？

Question

我有两个活动。 第一个活动具有不同的布局，可打开另一个活动。 在另一个活动中，我有一个分段的单选按钮组，我要对其进行设置，以根据在第一个活动中单击的布局进行检查。 要检查单选按钮，我使用了此功能。

segmented5.check（R.id.pickupbakButton）;

这会将按钮设置为选中状态，但由于我在布局中进行了其他更改，因此我希望从其他活动中对其进行检查。

我有这样的第一次活动：

并说“ PICKUPBOX / BLIND VAN”的点击

它应该显示皮箱/百叶窗厢的单选按钮已选中。

我该如何实现？

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
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_go_box_pickup);
        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);

                return;

            case R.id.engkelbakButton:

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

                return;

            case R.id.engkelboxButton:

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

                return;
            default:

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

Answer 1

在GoBoxActivity的 onClick内修改代码，如下所示

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

在PickupBoxActivity中 ，执行以下操作

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

之后

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

让我进一步了解任何问题。
