我想创建一个类似表格的视图,其中包含大量的列(7-10),而标题行始终可见(即使向下滚动时也是如此),并且第一列在水平滚动时也始终可见。
我试着把一个列表视图放在一个HorizontalScrollView中,它允许我显示一个列表,它有水平和垂直滚动,但没有静态列/标题。我试图避免使用多个视图,并在用户滚动时在它们之间进行同步。
稍后,我将不得不控制视图内部的事件,比如行/列单击,因此应该使用自定义适配器。
有什么想法吗?

您可以查看我创建的这个库:https://github.com/InQBarna/TableFixHeaders
我认为它实现了您正在寻找的小部件。

我会选择由TableRow
填充的TableLayout
。
下面的代码演示了如何实现这一点。
package com.test;
import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.view.Gravity;
import android.widget.TableLayout;
import android.widget.TableRow;
import android.widget.TableRow.LayoutParams;
import android.widget.TextView;
public class TableLayoutTest extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.table_layout);
TableRow.LayoutParams wrapWrapTableRowParams = new TableRow.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
int[] fixedColumnWidths = new int[]{20, 20, 20, 20, 20};
int[] scrollableColumnWidths = new int[]{20, 20, 20, 30, 30};
int fixedRowHeight = 50;
int fixedHeaderHeight = 60;
TableRow row = new TableRow(this);
//header (fixed vertically)
TableLayout header = (TableLayout) findViewById(R.id.table_header);
row.setLayoutParams(wrapWrapTableRowParams);
row.setGravity(Gravity.CENTER);
row.setBackgroundColor(Color.YELLOW);
row.addView(makeTableRowWithText("col 1", fixedColumnWidths[0], fixedHeaderHeight));
row.addView(makeTableRowWithText("col 2", fixedColumnWidths[1], fixedHeaderHeight));
row.addView(makeTableRowWithText("col 3", fixedColumnWidths[2], fixedHeaderHeight));
row.addView(makeTableRowWithText("col 4", fixedColumnWidths[3], fixedHeaderHeight));
row.addView(makeTableRowWithText("col 5", fixedColumnWidths[4], fixedHeaderHeight));
header.addView(row);
//header (fixed horizontally)
TableLayout fixedColumn = (TableLayout) findViewById(R.id.fixed_column);
//rest of the table (within a scroll view)
TableLayout scrollablePart = (TableLayout) findViewById(R.id.scrollable_part);
for(int i = 0; i < 10; i++) {
TextView fixedView = makeTableRowWithText("row number " + i, scrollableColumnWidths[0], fixedRowHeight);
fixedView.setBackgroundColor(Color.BLUE);
fixedColumn.addView(fixedView);
row = new TableRow(this);
row.setLayoutParams(wrapWrapTableRowParams);
row.setGravity(Gravity.CENTER);
row.setBackgroundColor(Color.WHITE);
row.addView(makeTableRowWithText("value 2", scrollableColumnWidths[1], fixedRowHeight));
row.addView(makeTableRowWithText("value 3", scrollableColumnWidths[2], fixedRowHeight));
row.addView(makeTableRowWithText("value 4", scrollableColumnWidths[3], fixedRowHeight));
row.addView(makeTableRowWithText("value 5", scrollableColumnWidths[4], fixedRowHeight));
scrollablePart.addView(row);
}
}
//util method
private TextView recyclableTextView;
public TextView makeTableRowWithText(String text, int widthInPercentOfScreenWidth, int fixedHeightInPixels) {
int screenWidth = getResources().getDisplayMetrics().widthPixels;
recyclableTextView = new TextView(this);
recyclableTextView.setText(text);
recyclableTextView.setTextColor(Color.BLACK);
recyclableTextView.setTextSize(20);
recyclableTextView.setWidth(widthInPercentOfScreenWidth * screenWidth / 100);
recyclableTextView.setHeight(fixedHeightInPixels);
return recyclableTextView;
}
}
页眉是不会垂直滚动的部分;这就是为什么你需要在列上设置固定宽度的原因。从你不想滚动的第一列开始,你必须为此在行上设置一个固定的高度。
下面是布局XML
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center_horizontal"
android:id="@+id/fillable_area">
<TableLayout
android:id="@+id/table_header"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<ScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<LinearLayout android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center_horizontal"
android:id="@+id/fillable_area">
<TableLayout
android:id="@+id/fixed_column"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<HorizontalScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TableLayout
android:id="@+id/scrollable_part"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</HorizontalScrollView>
</LinearLayout>
</ScrollView>
</LinearLayout>
在刚刚加载时,输出如下所示
像这样滚动到右边和底部

创建将成为标头的TableLayout,并在其下面放置ScrollView中的表本身,如下所示:
<TableLayout
android:id="@+id/tbl_header"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:divider="@drawable/table_divider"
android:showDividers="middle"
android:background="@drawable/table_header_backdround"
/>
<ScrollView android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TableLayout
android:id="@+id/tbl_relesed_wake_locks"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:divider="@drawable/table_divider"
android:showDividers="middle"
android:stretchColumns="1,2"
android:background="@drawable/table_backdround"
/>
</ScrollView>
当你要用数据填充你的头部时,添加下一段代码:
table.post(new Runnable() {
@Override
public void run() {
TableRow tableRow = (TableRow)table.getChildAt(0);
for(int i = 0; i < headerRow.getChildCount(); i++){
headerRow.getChildAt(i).setLayoutParams(new TableRow.LayoutParams(tableRow.getChildAt(i).getMeasuredWidth(), tableRow.getChildAt(i).getMeasuredHeight()));
}
}
});
就这样。
