Java 用按钮链接气泡选择器中的气泡

我使用气泡选择器库。我希望能够将我的气泡选择器（我有10个）中的每个气泡与一个按钮链接，该按钮将执行10个活动中的另一个

我想你必须给OnBubbleSelected添加一些代码

另外，我对编码是新手，所以我很难这么做。谢谢你的回答

public class Main777Activity extends AppCompatActivity {


    BubblePicker picker;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main777);

        final String[] titles = getResources().getStringArray(R.array.hashtags);
        final TypedArray colors = getResources().obtainTypedArray(R.array.colors);

        picker = findViewById(R.id.picker);
        picker.setAdapter(new BubblePickerAdapter() {
            @Override
            public int getTotalCount() {
                return titles.length;
            }

            @NotNull
            @Override
            public PickerItem getItem(int position) {
                PickerItem item = new PickerItem();
                item.setTitle(titles[position]);
                item.setGradient(new BubbleGradient(colors.getColor((position * 2) % 8, 0),
                        colors.getColor((position * 2) % 8 + 1, 0), BubbleGradient.VERTICAL));
                item.setTextColor(ContextCompat.getColor(Main777Activity.this, android.R.color.white));
                return item;
            }



        });


        picker.setBubbleSize(45);
        picker.setSwipeMoveSpeed(2f);
        picker.setAlwaysSelected(false);
        picker.setMaxSelectedCount( 1 );



        picker.setListener(new BubblePickerListener() {
            @Override
            public void onBubbleSelected(@NotNull PickerItem item) {
                picker.getSelectedItems();
                picker.setListener(this);

            }

            @Override
            public void onBubbleDeselected(@NotNull PickerItem item) {

            }
        });
    }
    @Override
    protected void onResume() {
        super.onResume();
        picker.onResume();
    }

    @Override
    protected void onPause() {
        super.onPause();
        picker.onPause();
    }
}

欢迎来到Stackoverflow社区

现在，您希望为每个选定的气泡项目启动不同的活动；如果我错了，请纠正我

为此，您需要在

BubblePicker

小部件的

BubblePickerListener

的

onBubbleSelected（）

中启动活动意图，并利用

item

参数区分项目；您可以使用

item.getTitle（）

进行此操作

为此：

picker.setListener(new BubblePickerListener() {
    @Override
    public void onBubbleSelected(@NotNull PickerItem item) {

        if (item.getTitle() != null) {
            switch(item.getTitle()) {

                case "item1":
                    // start activity of item1 
                    break;

                case "item2":
                    // start activity of item2
                    break;

                case "item3":
                    // start activity of item3
                    break;
            }

        }
    }

    @Override
    public void onBubbleDeselected(@NotNull PickerItem item) {

    }
});

下面是一个完整的示例，所有项目都使用一个单独的活动，但为每个项目传递不同的值（项目标题）

它看起来怎么样

您能否提供一些示例，说明如何编写当前执行的代码及其输出？提供所需的电流输出将有助于明确ask。如果有错误，请添加其stacktrace。
