我在为android编写一段代码时遇到了问题。我正在使用eclipse开发环境。我想要完成的是让一周中的几天在表格的第一行（六行）上均匀分布。我无法弄清楚如何使它实际上扩散出来，而不仅仅是在一个组中。 （是的，我尝试过使用重量）。我的代码如下。我提前为问题中的任何拼写错误或代码中的评论道歉。
package A3.cal;
import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.widget.FrameLayout;
import android.widget.LinearLayout;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.TableLayout;
import android.widget.TableRow;
public class A3Activity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState); //it works dont touch it...
setContentView(R.layout.main); //old Content View
MonthView(); //setup the initial view
}
public void MonthView(){
TableRow[] tableRows = new TableRow[6]; //create table rows for the table
LinearLayout[] dayHeaderFrames = new LinearLayout[7]; //create the frame layouts for the table headers
TextView[] days = new TextView[7]; //create new text views array
days = populateDays(0); //make the textviews say the proper days (this can be faster by manipulating the strings and then adding to textview)
TableLayout monthView = (TableLayout) findViewById(R.id.monthView); //find month View in the xml file
LinearLayout headerLayout = new LinearLayout(this); //create the linear layout that will hold the frame layouts for the text views**
headerLayout.setBackgroundColor(Color.WHITE); //make the linear layouts white
LinearLayout.LayoutParams ll = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT, 1f); //create the layout perameters for childeren
for(int i = 0; i < 6; i++){ //create the table rows
tableRows[i] = new TableRow(this); //create the new rows
}
tableRows[0].addView(headerLayout); //add the header layout to the first row
tableRows[0].setBackgroundColor(Color.RED); //set the background table row (only the first one which I am concentrating on) to red
monthView.setBackgroundColor(Color.BLUE); // make the table blue
for(int i = 0; i < 7; i++){ //add the headers to the month day header row
dayHeaderFrames[i] = new LinearLayout(this); //create new frames
headerLayout.addView(dayHeaderFrames[i], ll); //add the frames to the first row in the table
dayHeaderFrames[i].addView(days[i]); //add the textview objects to the frames (the text view objects already have the correct text from when populate days was called)
}
for(int i = 0; i < 6; i++){ //add the rows to the month view
monthView.addView(tableRows[i]); //add the new rows to the table
}
}
public TextView[] populateDays(int startDay){
TextView[] daysTextViewArr = new TextView[7]; //create a textview array
String[] days = { "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"}; //days of the week
for(int i = 0; i < 7; i++){ //put the days into the order based upon the start day
daysTextViewArr[i] = new TextView(this); //create a new text view object
//the following logic puts the days into order
int day = i + startDay;
if(day > 6){ //if the day will exceed the array put it back to the begining
day = day - 7;
}
daysTextViewArr[i].setText(days[i]); //set the text in the text view to the propper day
}
return daysTextViewArr;
}
}
主要的
中的XML布局<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/ll"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<TableLayout
android:id="@+id/monthView"
android:layout_width="match_parent"
android:layout_height="match_parent">
</TableLayout>
回顾一下代码的工作原理，除了间隔线性布局/文本视图
我想提前感谢你帮助我解决这个（以及其他许多）问题。

解决方案很简单。您需要使用android：stretchColumns属性。 将以下示例翻译成您的代码
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/ll"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TableLayout
android:id="@+id/monthView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:stretchColumns="0,1,2,3,4,5">
</TableLayout>
</LinearLayout>
