这就是问题所在，我尝试使用 setPadding、setRight 和其他愚蠢的方法，但它们无济于事。
当达到显示限制时，我需要文本转到新行，所以，请帮助我。
它似乎只有当我用作 Target、Target.NONE 时才有位置，其他时候，当我使用一些按钮等时，线条按应有的方式下降，一切正常，但我需要这个介绍性文本首先出现没有选择任何特定元素的时间。

我通过将子视图添加到ShowCaseView.
升级版，
我被要求分享解决方案，所以我将分享我使用的所有代码。
这是我使用的完整代码ShowCaseView：我使用 aFragment来显示它，因此我不需要每次都复制代码，我还做了一些改进以使使用它的生活更轻松：
frShowCase.java:
/**

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();

这是我用来传递到该片段的目标Targets的Activities类
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;
}
}
这是用于 ShowCaseView 的自定义布局的 xml，当默认人无法完成他的工作时使用（文本从屏幕上消失，按钮不在它应该在的位置等等）
陈列柜文本.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_height="fill_parent"
android:id="@+id/scvShowCase" >
<LinearLayout

android:layout_height="match_parent">

</LinearLayout>
</ScrollView>
</FrameLayout>
至于cbActivity.BoolFromPref(getLocalClassName(), false)-我使用共享首选项来检查此 Activity 是否已启动，因此此行检查此值，同样在 Fragment 的代码中，您会看到在演示时阻止所有布局视图，如果您不需要它-不要叫那个。
如果您需要使用自定义视图，请在创建Target这样的时添加“true”：
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，cbActivity - 活动的 mybase 类，我在这里使用它作为对常用方法和变量的引用，因此在该类中声明了位置枚举，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();
}
