当单击按钮时,我成功创建了一个动态TextView和一个按钮,TextView的值发生了变化。
但问题是我有一个最终的“提交按钮”之外的循环,应该得到每个TextView的INDIVIDUAL值,我不能想办法如何做到这一点,有人可以给我一个方法,谢谢! PLS是不错..获取动态生成的文本值的方法
代码
Cursor citem= sdb.rawQuery("SELECT * FROM ITEM INNER JOIN CATEGORY ON item.categoryid = category.id where category.categoryname='"+fcat+"'", null);
ScrollView scrollView= new ScrollView(this);
LinearLayout mainLayout= new LinearLayout(this);
mainLayout.setOrientation(LinearLayout.VERTICAL);
Button border = new Button(this);
border.setId(Integer.parseInt(cuser.getString(cuser.getColumnIndex("id"))));;
border.setText("ORDER");
while (citem.moveToNext())
{
byte[] blob =citem.getBlob(citem.getColumnIndex("itemimage"));
int id = Integer.parseInt(citem.getString(citem.getColumnIndex("id")));
LinearLayout linearLayout = new LinearLayout(this);
linearLayout.setOrientation(LinearLayout.HORIZONTAL);
linearLayout.setTag(id);
int i;
ImageView iv = new ImageView(this);
iv.setId(id);
iv.setImageBitmap(dh.getPhoto(blob));
final TextView txtquantity = new TextView(this);
txtquantity.setId(id);
txtquantity.setText("0");
txtquantity.setTextSize(20);
final TextView txtprice = new TextView(this);
txtprice.setId(id);
txtprice.setText(citem.getString(citem.getColumnIndex("itemprice")));
txtprice.setTextSize(30);
ImageButton btn1 = new ImageButton(this);
btn1.setId(id);
final int id_ = btn1.getId();
btn1.setImageResource(R.drawable.ic_launcher);
btn1.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
int i = 0;
i=Integer.parseInt((String) txtquantity.getText())+1;
txtquantity.setText(String.valueOf(i));
totalprice.setText(String.valueOf(Integer.parseInt(totalprice.getText().toString())+(Integer.parseInt(txtprice.getText().toString())*1)));
}
});
ImageButton btn2 = new ImageButton(this);
btn2.setId(id);
final int id2_ = btn2.getId();
btn2.setImageResource(R.drawable.ic_launcher);
btn2.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
if(Integer.parseInt((String)txtquantity.getText())<=0)
{
}
else
{
int i=0;
i= Integer.parseInt((String) txtquantity.getText())-1;
txtquantity.setText(String.valueOf(i));
totalprice.setText(String.valueOf(Integer.parseInt(totalprice.getText().toString())-(Integer.parseInt(txtprice.getText().toString())*1)));
}
}
});
linearLayout.addView(iv);
linearLayout.addView(txtprice);
linearLayout.addView(btn1);
linearLayout.addView(txtquantity);
linearLayout.addView(btn2);
mainLayout.addView(linearLayout);
}
mainLayout.addView(totalprice);
mainLayout.addView(border);
scrollView.addView(mainLayout);
setContentView(scrollView);
