我的Async任务按原样运行，我想通过意图将arraylists的对象传递给下一个活动，该活动将更新屏幕并构建一些视图。
我有我的构造函数：
Async(BigDecimal balance, Date SD, Integer Years, BigDecimal CPY, Date fPayDate, BigDecimal Nom, String PF, Context context) {
this.balance = balance;
this.SD = SD;
this.Years = Years;
this.CPY = CPY;
this.fPayDate = fPayDate;
this.Nom = Nom;
this.PF = PF;
this.context = context;
}
我尝试传递意图并开始活动：
@Override
protected void onPostExecute(arWrapper wrapper) {
super.onPostExecute(wrapper);
this.balAr = wrapper.balAr;
this.payAr = wrapper.payAr;
this.intAr = wrapper.intAr;
this.dateAr = wrapper.dateAr;
this.prinAr = wrapper.prinAr;
Intent intent = new Intent(context,scrollTable.class)
.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra("balance", new myParcelable(balAr, intAr, dateAr, prinAr, payAr));
context.startActivity(intent);
}
然后我尝试启动以下活动来创建动态表格布局：
public class scrollTable extends Activity
{
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
myParcelable object = getIntent().getParcelableExtra("balance");
ArrayList<BigDecimal> balAr = object.balAr;
ArrayList<BigDecimal> intAr = object.intAr;
ArrayList<Calendar> dateAr = object.dateAr;
ArrayList<BigDecimal> prinAr = object.prinAr;
ArrayList<BigDecimal> payAr = object.payAr;
String[] column = { "Payment", "Interest", "Principal",
"Balance"
};
int rl=balAr.size();
int cl=column.length;
ScrollView sv = new ScrollView(this);
TableLayout tableLayout = createTableLayout(dateAr, column,rl, cl, payAr, intAr, prinAr, balAr);
HorizontalScrollView hsv = new HorizontalScrollView(this);
hsv.addView(tableLayout);
sv.addView(hsv);
setContentView(sv);
}
private TableLayout createTableLayout(ArrayList rv, String [] cv,int rowCount, int columnCount, ArrayList pay, ArrayList intr, ArrayList prin, ArrayList bal)
{
// 1) Create a tableLayout and its params
TableLayout.LayoutParams tableLayoutParams = new TableLayout.LayoutParams();
TableLayout tableLayout = new TableLayout(this);
tableLayout.setBackgroundColor(Color.BLACK);
// 2) create tableRow params
TableRow.LayoutParams tableRowParams = new TableRow.LayoutParams();
tableRowParams.setMargins(1, 1, 1, 1);
tableRowParams.weight = 1;
SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy", Locale.US);
for (int i = 0; i < rowCount; i++)
{
// 3) create tableRow
TableRow tableRow = new TableRow(this);
tableRow.setBackgroundColor(Color.BLACK);
for (int j= 0; j < columnCount; j++)
{
// 4) create textView
TextView textView = new TextView(this);
// textView.setText(String.valueOf(j));
textView.setBackgroundColor(Color.WHITE);
textView.setGravity(Gravity.CENTER);
if (i ==0 && j==0)
{
textView.setText("Date");
}
else if(i==0)
{
Log.d("TAG", "set Column Headers");
textView.setText(cv[j-1]);
}
else if( j==0)
{
//set up for dates
Log.d("TAG", "Set Row Headers");
textView.setText(rv.get(i).toString());
}
else if (j == 1)
{
textView.setText(pay.get(i).toString());
}
else if (j == 2)
{
textView.setText(intr.get(i).toString());
}
else if (j == 3)
{
textView.setText(prin.get(i).toString());
}
else if (j == 4)
{
textView.setText(bal.get(i).toString());
}
// 5) add textView to tableRow
tableRow.addView(textView, tableRowParams);
}
// 6) add tableRow to tableLayout
tableLayout.addView(tableRow, tableLayoutParams);
}
return tableLayout;
}
}
为什么启动活动不正常？我没有得到任何错误消息，调试帧只是在它遇到新活动时就停止了。我也不确定主线程是否可以处理表格布局的所有动态创建。除了为什么这不起作用还有办法打破渲染计算？
