嘿我想让视图显示在已创建的最后一个视图下方。
显示如下:
我想让下一个视图显示在最后一个视图下方,因此对于添加的每个新视图,它显示如下。理解?
这是我的代码。 xml文件和java文件。
listitem.xml
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:id="@+id/linearId"
android:padding="6dip"

<ImageView
android:id="@+id/icon"
android:layout_width="wrap_content"

android:layout_marginRight="6dip"
android:src="@drawable/icon"

<LinearLayout

RatedCalls.java

private TableLayout table;

private TableRow row;
private TableRow row2;

List<String> ratedCalls = new ArrayList<String>();

LayoutInflater inflater = (LayoutInflater) this
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
LinearLayout ll = (LinearLayout) this.findViewById(R.id.linearId);
for (int i = 0; i < 1; i++) {
View item = inflater.inflate(R.layout.listitem, null);
TextView x = (TextView) item.findViewById(R.id.txt1);
x.setText(ratedCalls.get(0));
TextView ht = (TextView) item.findViewById(R.id.txt2);
ht.setText(ratedCalls.get(1));
ll.addView(item, ViewGroup.LayoutParams.WRAP_CONTENT);
}
}

您的问题是您应该使用列表适配器中的listitem.xml。您正在做的是,首先将内容视图设置为listitem.xml的实例,然后尝试插入listitem INTO listitem的第一个LinearLayout实例。您应该使用listitem.xml作为在自定义适配器的getView()
方法中充气的视图。有关示例,请参阅this question中的QuoteAdapter
课程,或者只搜索“自定义ArrayAdapter Android”,了解有关此主题的大量结果。

在您的xml文件中,将android:orientation
上的vertical
属性设置为<LinearLayout/>
:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:id="@+id/linearId"
android:padding="6dip"
android:orientation="vertical"/>
查看LinearLayout课程文档和orientation文档以获取更多信息。

mmm ...我完全不了解需要什么,但可能需要将android:orientation =“vertical”添加到LinearLayout,id =“linearId”。

要使用,您需要为每个inflater创建两个不同的xml
在布局文件夹中,新建xml layout / main2.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView
android:id="@+id/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="6dip"
android:src="@drawable/icon"
/>
<TextView
android:id="@+id/txt1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textSize="20sp"
android:gravity="center_vertical"
android:text="My Application"
/>
<TextView
android:id="@+id/txt2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:singleLine="true"
android:ellipsize="marquee"
android:text="Simple application that shows how to use RelativeLayout"
android:textSize="10sp"
/>
</LinearLayout>
然后是 layout / main.xml
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/linearId"
android:orientation="vertical"
>
<TextView android:id="@+id/rowCount" android:layout_width="wrap_content"
android:layout_height="wrap_content" ></TextView>
<LinearLayout
android:id="@+id/linearId2"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:padding="6dip">
</LinearLayout>
</LinearLayout>
然后,您可以设置活动,就像这样
private int ELEMENTINEACHROW=2 ;
private int NOOFROW = 4;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
LinearLayout ll = (LinearLayout) this.findViewById(R.id.linearId);
for (int j = 0; j < NOOFROW; j++) {
View itemMain = inflater.inflate(R.layout.main, null, false);
TextView rowCount = (TextView) itemMain.findViewById(R.id.rowCount);
rowCount.setText("Row:"+(j+1));
LinearLayout ll2 = (LinearLayout) itemMain.findViewById(R.id.linearId2);
for (int i = 0; i < ELEMENTINEACHROW; i++) {
View item = inflater.inflate(R.layout.main2, null, false);
TextView x = (TextView) item.findViewById(R.id.txt1);
x.setText("test");
TextView ht = (TextView) item.findViewById(R.id.txt2);
ht.setText("good");
ll2.addView(item, ViewGroup.LayoutParams.FILL_PARENT);
}
ll.addView(itemMain, ViewGroup.LayoutParams.FILL_PARENT);
}
}
希望它能给你这个想法。
