我不知道什麼是在下面code.But我知道問題是哪裏的問題arises.It是從方法createTL()
..它停止unfortunately.Help我解決這個疑難問題。要創建n行4專欄EditText
查看。 編輯:現在我初始化都等和tr..but錯誤仍然arises..Tis是更新的代碼創建表格佈局時遇到困難?
public TableLayout createTL(int r)
{
int c=4;
LayoutParams params = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);
myTL=new TableLayout(Ybus_Activity.this);
myTL.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT, TableRow.LayoutParams.WRAP_CONTENT));
myTL.setStretchAllColumns(true);
TableRow[] tr = new TableRow[r];
EditText[][] et = new EditText[r][c];
Arrays.fill(et,"0.0");
Arrays.fill(tr,et);
for(int i=0;i<r;i++)
{
for(int j=0;j<4;j++)
{
et[i][j].setLayoutParams(params);
et[i][j].setWidth(100);
et[i][j].setImeOptions(EditorInfo.IME_ACTION_NEXT);
et[i][j].setInputType(InputType.TYPE_CLASS_NUMBER);
et[i][j].setKeyListener(DigitsKeyListener.getInstance());
et[i][j].setMaxLines(1);
tr[i].addView(et[i][j]);
myTL.addView(tr[i]);
}
}
//I already have LinearLayout named "main" under onCreate() method...
//main.addView(myTL);
return myTL;
}
我logcat的:(更新)
