问题描述
我有这三个具有相同元素数量的列表
I have these three lists with the same number of elements
List<String>competitoinsIDs = new LinkedList<String>();
List<String>marks = new LinkedList<String>();
List<String>numOfQuestions = new LinkedList<String>();
我想将每个列表的第一个元素放在tablerow中,然后将每个列表的第二个元素放在tablerow中在另一个表格中,您能帮我吗,这是xml
I want to put the first element of each list in a tablerow , then the second element of each list in another tablerow, would you help me please, this is the xml
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TableLayout
android:id="@+id/tlMarksTable"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TableRow
android:id="@+id/tableRow1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="5dip"
android:weightSum="2" >
<TextView
android:id="@+id/tvMarksCompetitionID"
android:layout_weight="1"
android:text="Competition"
android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView
android:id="@+id/tvMarksMarks"
android:layout_weight="1"
android:text="Marks"
android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView
android:id="@+id/tvMarksQuestionsNum"
android:layout_weight="1"
android:text="Questions"
android:textAppearance="?android:attr/textAppearanceMedium" />
</TableRow>
</TableLayout>
</FrameLayout>
推荐答案
首先将XML文件更改为:
First change your XML file to:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TableLayout
android:id="@+id/tlMarksTable"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</TableLayout>
</FrameLayout>
我们将动态添加所有内容。
We'll add all the content dynamically.
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
List<String>competitoinsIDs = new LinkedList<String>();
List<String>marks = new LinkedList<String>();
List<String>numOfQuestions = new LinkedList<String>();
//make sure that the lists contain data or else display will be blank screen
TableRow.LayoutParams params1=new TableRow.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT,1.0f);
TableRow.LayoutParams params2=new TableRow.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT);
TableLayout tbl=(TableLayout) findViewById(R.id.tlMarksTable);
for(int ctr=0;ctr<marks.size();ctr++)
{
//Creating new tablerows and textviews
TableRow row=new TableRow(this);
TextView txt1=new TextView(this);
TextView txt2=new TextView(this);
TextView txt3=new TextView(this);
//setting the text
txt1.setText(competitoinsIDs.get(ctr));
txt2.setText(marks.get(ctr));
txt3.setText(numOfQuestions.get(ctr));
txt1.setLayoutParams(params1);
txt2.setLayoutParams(params1);
txt3.setLayoutParams(params1);
//the textviews have to be added to the row created
row.addView(txt1);
row.addView(txt2);
row.addView(txt3);
row.setLayoutParams(params2);
tbl.addView(row);
}
}
