我不明白为什么我的editText没有出现。我很困惑的是，我可以在我的日食大纲中看到editText。

    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:hint="@string/editTextHINT1"

Because you have passed android:layout_width="fill_parent" in your button and its taking whole width of your screen.Either change the android:orientation="horizontal"property of LinearLayout to vertical or android:layout_width="fill_parent" to wrap_content.

因为你已经在你的按钮中传递了android：layout_width =“fill_parent”并且它占据了你屏幕的整个宽度。要么将LinearLayout的android：orientation =“horizontal”属性改为vertical，要么将android：layout_width =“fill_parent”更改为wrap_content。

Try this.

尝试这个。

Change your orientation of LinearLayout to "vertical". Then they will be aligned vertically. This is happening because you are setting layout_width="fill_parent" in your Button which will fill the entire parent and thus will not show your EditText box.

将LinearLayout的方向更改为“垂直”。然后它们将垂直对齐。发生这种情况是因为您在Button中设置了layout_width =“fill_parent”，它将填充整个父级，因此不会显示您的EditText框。

Let me thinks what exactly you want to do?

让我想想你到底想做什么？

 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent" 
    android:orientation="vertical" >

    <LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content" 
    android:orientation="horizontal" >
    <Button
        android:id="@+id/buttonTESTER1"
        android:layout_width="100dp"
        android:layout_height="wrap_content"
        android:text="@string/btnTester1_text" 
    />

    <EditText
        android:id="@+id/editTextTESTER1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:hint="@string/editTextHINT1"
        android:inputType="text"
    />

    </LinearLayout>
    </LinearLayout>
