我有一个活动,其中包含在时间轴中组织的活动。但它看起来很难看。
我想设计一个更漂亮的时间表,就像这个。
有没有简单的方法或库在元素之间画线,就像我的例子一样?
<ScrollView
android:layout_marginTop="10dp"
android:layout_marginLeft="10dp"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_below="@+id/text_data"
android:layout_above="@+id/button_trimite"
android:id="@+id/scroll_timeline"
android:layout_marginBottom="7dp"
>
<TableLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/timelineTable"
>
</TableLayout>
</ScrollView>
这是我的xml。但我的TableLayout是动态生成的,因为我需要对事件进行排序。
for (final Event e : events) {
if(e.getDate().equals(dataComp)) {
//tablerow with event entry
final TableRow row = new TableRow(getActivity());
row.setLayoutParams(new TableRow.LayoutParams(
TableRow.LayoutParams.MATCH_PARENT,
TableRow.LayoutParams.WRAP_CONTENT));
if (indexForDrawable % 2 == 0)
row.setBackgroundResource(R.drawable.marcaj_event_albastru);
else
row.setBackgroundResource(R.drawable.marcaj_event_portocaliu);
TextView txtEvent = new TextView(getActivity());
txtEvent.setText(" "+ e.getHour() +"-"+e.getType()+"-"+e.getTitle());
txtEvent.setTextColor(Color.BLACK);
txtEvent.setTextSize(TypedValue.COMPLEX_UNIT_DIP, trEvent);
txtEvent.setTypeface(Typeface.create(tf, Typeface.BOLD));
row.addView(txtEvent);
row.setClickable(true);
final String date = e.getDate(), hour = e.getHour(), title = e.getTitle(),
type = e.getType(), descriere = e.getDescriere();
final int finalResource = resource;
final int finalIndexForDrawable = indexForDrawable;
row.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
row.setBackground(getActivity().getResources().getDrawable(finalResource));
showPopup2(date, hour, type, title, descriere, row, finalIndexForDrawable);
}
});
timelineTable.addView(row, new TableLayout.LayoutParams(
TableLayout.LayoutParams.MATCH_PARENT,
TableLayout.LayoutParams.WRAP_CONTENT));
indexForDrawable++;
}
else {
//tablerow with date
final TableRow row = new TableRow(getActivity());
row.setLayoutParams(new TableRow.LayoutParams(
TableRow.LayoutParams.MATCH_PARENT,
TableRow.LayoutParams.WRAP_CONTENT));
TextView txtEvent = new TextView(getActivity());
// txtEvent.setText(“\ n”+ dataSplit1 [0] + months.indexOf(dataSplit1 1)); txtEvent.setText(“\ n”+ e.getDate()。substring(0,5)); txtEvent.setTextSize(TypedValue.COMPLEX_UNIT_DIP,trDate); row.addView(txtEvent); timelineTable.addView(row,new TableLayout.LayoutParams( TableLayout.LayoutParams.MATCH_PARENT, TableLayout.LayoutParams.WRAP_CONTENT)); dataComp = e.getDate();
//tablerow with event entry
final TableRow row3 = new TableRow(getActivity());
row3.setLayoutParams(new TableRow.LayoutParams(
TableRow.LayoutParams.MATCH_PARENT,
TableRow.LayoutParams.WRAP_CONTENT));
if (indexForDrawable % 2 == 0)
row3.setBackgroundResource(R.drawable.marcaj_event_albastru);
else
row3.setBackgroundResource(R.drawable.marcaj_event_portocaliu);
TextView txtEvent3 = new TextView(getActivity());
txtEvent3.setText(" "+ e.getHour() +"-"+e.getType()+"-"+e.getTitle());
txtEvent3.setTextColor(Color.BLACK);
txtEvent3.setTextSize(TypedValue.COMPLEX_UNIT_DIP, trEvent);
txtEvent3.setTypeface(Typeface.create(tf, Typeface.BOLD));
row3.addView(txtEvent3);
row3.setClickable(true);
final String date3 = e.getDate(), hour3 = e.getHour(), title3 = e.getTitle(),
type3 = e.getType(), descriere3 = e.getDescriere();
timelineTable.addView(row3, new TableLayout.LayoutParams(
TableLayout.LayoutParams.MATCH_PARENT,
TableLayout.LayoutParams.WRAP_CONTENT));
indexForDrawable++;
}

您可能需要创建自己的自定义适配器,但我使用的是数组适配器供您参考。同时为列表视图提供项目布局,希望您相应地管理代码。
<强> items.xml 强>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical" >
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="match_parent" >
<View
android:layout_width="2dp"
android:layout_height="match_parent"
android:layout_centerVertical="true"
android:layout_marginLeft="10dp"
android:background="@android:color/black" />
<View
android:id="@+id/view1"
android:layout_width="7dp"
android:layout_height="7dp"
android:layout_centerVertical="true"
android:layout_marginLeft="7dp"
android:background="@drawable/dot" />
</RelativeLayout>
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="10dp"
android:padding="20dp"
android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>
dot.xml 这是一个可绘制的
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval" >
<stroke
android:width="1dp"
android:color="@android:color/black" />
<solid android:color="@android:color/white" />
在活动中你可以使用这样的适配器:
list.setAdapter(new ArrayAdapter<String>(this, R.layout.item, R.id.textView1, items));
希望这有帮助!

如果您只想显示一行,我建议您为此创建一个Drawable。 下面是一个小例子: 布局文件
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/line">
</LinearLayout>
和line.xml Drawable
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:left="3dp">
<shape >
<stroke android:width="1dp" android:color="@android:color/holo_purple"/>
</shape>
</item>
<item android:left="4dp">
<shape>
<solid android:color="#ffffff"/>
</shape>
</item>
</layer-list>
也可以更改图层列表以使用其他Drawables作为您已使用的图纸。
使用draw-9的示例可能如下所示: line.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<nine-patch android:src="@drawable/point" android:dither="true"/>
</item>
<!-- <item android:left="3dp">
<shape >
<stroke android:width="1dp" android:color="@android:color/holo_purple"/>
</shape>
</item>
<item android:left="4dp">
<shape>
<solid android:color="#ffffff"/>
</shape>
</item> -->
</layer-list>
布局:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="New Text"
android:background="@drawable/line" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="New Text"
android:background="@drawable/line"/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="New Text"
android:layout_gravity="center_horizontal"
android:background="@drawable/line" />
</LinearLayout>

要应用绘制九贴片,您必须在边框上标记要用黑色拉伸的部分。
