Question

我有一个带有几个按钮的简单LinearLayout，其中状态颜色/文本根据底层服务的状态而变化，这样可以正常工作。

然而按钮只能在右上角点击???

按钮allSystemServicesToggleButton，我已经在这篇文章中包含了实现，只在右侧/右侧点击了???

这是我的片段xml布局＆amp; “Show Layout bounds”设置为true的实际屏幕截图：

    private static final int CHECK_BT_CODE = 1;
    private static final int CHECK_TTS_CODE = 2;

    @Override
    public Fragment getItem(int position) {

        switch(position) {
            case 0:
                returnFragment = ServicesFragment.newInstance();
                break;
            case 1:

                break;
            default:

        }

        return returnFragment;
    }

    @Override
    public int getCount() {
        return 2;
    }

    public CharSequence getPageTitle(int position) {
        CharSequence title;
        switch (position) {
            case 0:
                title = "Services";

仅用于角点击使用这种逻辑

                    android:background="@color/colorAccent" />

                <TextView
