ShowcaseView 的详情文本不会换行

Question

就是这个问题，我试过使用setPadding、setRight和其他愚蠢的方法，但它们没有帮助。

我需要文本在达到显示限制时换行，所以请帮助我。

它似乎只有在我用作目标时才有用，Target.NONE，其他时候，当我使用某些按钮等时，线条会正常下降，一切正常，但我需要这个介绍在未选择任何特定元素的情况下首次显示的文本。

Answer 1

我通过向 ShowCaseView 添加子视图解决了问题。

UPD,

我被要求分享解决方案，所以我将分享我使用的所有代码。

这是我使用 ShowCaseView 的完整代码：我使用 Fragment 来展示它，因此我不需要每次都复制代码，我还做了一些改进，让使用起来更轻松：

frShowCase.java:

/**
 * Created by Movsar Bekaev on 02/09/2015.
 */
public class frShowCase extends Fragment {
    static boolean is_sc_done;
    static ArrayList<xSchowCaseTarget> elements;
    static ShowcaseView sv;

    int svStep = 0;
    RelativeLayout.LayoutParams svButtonParams;
    TextView tvSvTitle, tvSvDetail;
    View additional_view = null;
    Handler mHandler;


    //SHOWCASE THING************************************
    private View.OnClickListener showCaseListener = new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            sv.hideButton();
            Handler handler = new Handler();
            handler.postDelayed(new Runnable() {
                public void run() {
                    showCaseSwitcher();
                    sv.showButton();
                }
            }, 50);
        }
    };


    public static frShowCase newInstance(ArrayList<xSchowCaseTarget> _elements) {
        frShowCase f = new frShowCase();
        Bundle args = new Bundle();
        elements = new ArrayList<xSchowCaseTarget>();
        sv = null;
        for (xSchowCaseTarget se : _elements) {
            elements.add(se);
        }
        is_sc_done = false;
        f.setArguments(args);
        return f;
    }

    public void svSetButtonPosition(cbActivity.position buttonPortraitPosition) {
        switch (buttonPortraitPosition) {
            case BOTTOM_LEFT:
                svButtonParams = new RelativeLayout.LayoutParams((int) getActivity().getResources().getDimension(R.dimen.btns_width), (int) getActivity().getResources().getDimension(R.dimen.btns_heigh));

}

这是我用来将 Targets 从 Activities 传递到该片段

的目标的 class

xShowCaseTargets.java

 import com.github.amlcurran.showcaseview.targets.Target;

    /**
     * Created by Movsar Bekaev on 15/09/2015.
     */
    public class xSchowCaseTarget{
        protected cbActivity.position b_pos = cbActivity.position.BOTTOM_RIGHT;
        protected Target target = null;
        protected String title = "";
        protected String description = "";
        protected boolean use_splashscreen = false;

        public xSchowCaseTarget(Target target, String title, String desc, cbActivity.position position, Boolean useSplash) {
            this.b_pos = position;
            this.target = target;
            this.title = title;
            this.description = desc;
            this.use_splashscreen = useSplash;
        }

        public xSchowCaseTarget(Target target, String title, String desc, cbActivity.position position) {
            this.b_pos = position;
            this.target = target;
            this.title = title;
            this.description = desc;
            this.use_splashscreen = false;
        }    
    }

这是 ShowCaseView 自定义布局的 xml，当默认布局无法完成其工作时使用（文本从屏幕上消失，按钮不在应有的位置等）

showcase_text.xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="wrap_content"
    android:layout_height="wrap_content">

    <ScrollView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:id="@+id/scvShowCase" >

        <LinearLayout
            android:orientation="vertical"
            android:layout_width="match_parent"
            android:layout_height="match_parent">

            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="@string/welcome"
                android:id="@+id/tvSvTitle"
                android:layout_gravity="center_horizontal"
                android:layout_marginTop="50dp"
                android:textColor="?attr/color_7"
                android:textSize="@dimen/h1_size"
                android:textStyle="bold" />

            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="@string/welcome_text"
                android:id="@+id/tvSvDetailText"
                android:layout_gravity="center_horizontal"
                android:textColor="?attr/color_4"
                android:layout_marginTop="30dp"
                android:layout_marginLeft="5dp"
                android:layout_marginRight="5dp"
                android:textSize="@dimen/text_normal_size"
                android:gravity="center" />
        </LinearLayout>
    </ScrollView>

</FrameLayout>

至于 cbActivity.BoolFromPref(getLocalClassName(), false) - 我使用共享首选项来检查这个 Activity 是否已经启动，所以这一行检查这个值，同样在 Fragment 的代码中你看到阻止布局的所有视图在演示时，如果您不需要它 - 不要调用它。

如果您需要使用自定义视图，您可以在创建 Target 时添加 "true"，如下所示：

svElements.add(new xSchowCaseTarget(Target.NONE, getString(R.string.welcome), getString(R.string.welcome_text), position.FILL_BOTTOM, true));

最后一件事是，活动的 cbActivity - mybase class，我在这里使用它作为对常用方法和变量的引用，所以位置枚举在 class，它看起来像：

 public enum position {TOP_RIGHT, TOP_LEFT, BOTTOM_RIGHT, BOTTOM_LEFT, CENTER, BOTTOM_CENTER, CENTER_TOP, FILL_BOTTOM, FILL_TOP}

这是我如何从活动中调用 ShowcaseView 的示例：

 if (cbActivity.BoolFromPref(getLocalClassName(), false)) {
            ArrayList<xSchowCaseTarget> svElements = new ArrayList<xSchowCaseTarget>();
            svElements.add(new xSchowCaseTarget(Target.NONE, getString(R.string.welcome), getString(R.string.welcome_text), position.FILL_BOTTOM, true));
            svElements.add(new xSchowCaseTarget(new ViewTarget(R.id.xxx, ActMain.this), getString(R.string.xxx), getString(R.string.xxx), position.BOTTOM_LEFT));
            svElements.add(new xSchowCaseTarget(new ViewTarget(R.id.xxx, ActMain.this), getString(R.string.xxx), getString(R.xxx), position.BOTTOM_RIGHT));
            if (isThereActionMenuButton())
                svElements.add(new xSchowCaseTarget(new ActionViewTarget(ActMain.this, ActionViewTarget.Type.OVERFLOW), getString(R.string.xxx), getString(R.string.xxx), position.FILL_BOTTOM));
            svElements.add(new xSchowCaseTarget(new ViewTarget(R.id.xxx, ActMain.this), getString(R.string.xxx), getString(R.string.xxx), position.CENTER));

            frShowCase frSC = frShowCase.newInstance(svElements);
            fm.beginTransaction().add(frSC , "xxx").commit();
        }

ShowcaseView 的详情文本不会换行

ShowcaseView's details text won't go to the new line
