我是Android新手 我想放这样的控件,但我不能:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum = "1.0"
android:orientation="horizontal"
android:background = "#faadadad" >
<TextView
android:layout_width="match_parent"
android:layout_height="44dp"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="Final"
android:id="@+id/textView4"
android:layout_gravity="center_horizontal" />
<LinearLayout android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.8">
<EditText
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft = "2dip"
android:layout_marginTop = "1dip"
android:layout_marginBottom = "1dip"
android:id="@+id/edit1"/>
</LinearLayout>
<LinearLayout android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.8">
<EditText
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft = "2dip"
android:layout_marginTop = "1dip"
android:layout_marginBottom = "1dip"
android:id="@+id/edit2" />
</LinearLayout>
<Button android:text = "grade:"
android:layout_width = "0dip"
android:layout_height="wrap_content"
android:layout_weight = "0.2"/>
</LinearLayout>
使用上面的代码,edittext1和edittext2以及textview2显示在屏幕外和textview1下

您可以使用此xml作为示例,只需替换为您的值
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:weightSum = "1.0"
android:orientation="vertical"
android:background = "#faadadad" >
<TextView
android:id="@+id/textView4"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center_horizontal"
android:text="Final"
android:textAppearance="?android:attr/textAppearanceMedium" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<EditText
android:id="@+id/EditText"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="1dip"
android:layout_marginLeft="2dip"
android:layout_marginTop="1dip"
android:hint="Search Terms" />
<EditText
android:id="@+id/EditText1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="1dip"
android:layout_marginLeft="2dip"
android:layout_marginTop="1dip"
android:hint="Another" />
<Button
android:id="@+id/Button"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_weight="0.2"
android:text="grade:" />
</LinearLayout>
</LinearLayout>

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
删除:
android:weightSum = "1.0"
变化:
android:orientation="horizontal"
垂直:
android:orientation="vertical"
这没关系
android:background = "#faadadad" >
<TextView
android:layout_width="match_parent"
android:layout_height="44dp"
android:textAppearance="?android:attr/textAppearanceMedium"
android:text="Final"
android:id="@+id/textView4"
android:layout_gravity="center_horizontal" />
变化:
<LinearLayout android:layout_width="0dp"
为:
<LinearLayout android:layout_width="match_parent"
确定:
android:layout_height="wrap_content"
删除:
android:layout_weight="0.8">
确定:
<EditText
变化:
android:layout_width="fill_parent"
到:
android:layout_width="0dp"
确定:
android:layout_height="wrap_content"
添加:
android:layout_weight="1"
确定:
android:layout_marginLeft = "2dip"
android:layout_marginTop = "1dip"
android:layout_marginBottom = "1dip"
android:hint="Search Terms" />
您可以尝试添加另一个EditText(复制粘贴)
删除:
</LinearLayout>
确定:
<Button android:text = "grade:"
android:layout_width = "0dip"
android:layout_height="wrap_content"
变化:
android:layout_weight = "0.2"/>
为:
android:layout_weight = "1"/>
添加:
</LinearLayout>
确定:
</LinearLayout>
