我使用alert dailog作为号码选择器,我可以选择值并将其设置为我的textview,但我想要的是,如果我选择从数字选择器中选择5,那么它将设置为TextView的,并再次,如果我点击的TextView然后5必须集中或选择numberpicker以前选择的值的开始号码选择器
public void qtyshow()
{
final AlertDialog.Builder alert = new AlertDialog.Builder(ProductView.this);
alert.setTitle("Select the Qty: ");
final NumberPicker np = new NumberPicker(ProductView.this);
np.setMaxValue(20); // max value 20
np.setMinValue(1); // min value 0
np.setWrapSelectorWheel(false);
alert.setView(np);
alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
proqty.setText(String.valueOf(np.getValue())); //set the value to textview
// Do something with value!
Float mulprice=Float.parseFloat(packlist.get(0).getProductPack_SP());
int mulqty= np.getValue();
Float total=mulprice*mulqty;
packsp.setText("$" + String.format("%.2f%n", total));
System.out.println("price test" + packlist.get(0).getProductPack_SP() + "," + mulprice + "," + mulqty + "," + String.format("%.2f%n", total));
Float mulelseprice=Float.parseFloat(packlist.get(0).getProductPack_ElseWhere());
Float totalelse=mulelseprice*mulqty;
packelsewhere.setText("$" + String.format("%.2f%n", totalelse));
}
});
alert.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
// Cancel.
}
});
alert.show();
}
