【问题描述】：
在我设置一些 if else 条件之前，我的代码运行良好。 我认为 for 循环中存在优化问题，但没有得到它
btSetQuantity.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if (etbillQuantity.getText().toString().equals("")) {
Toast.makeText(getApplicationContext(),
"Quantity Not Entered", Toast.LENGTH_SHORT)
.show();
InputMethodManager imm = (InputMethodManager) getSystemService(context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(
etbillQuantity.getWindowToken(), 0);
alertDialog.dismiss();
} else if (Double.parseDouble(etbillQuantity.getText()
.toString()) > initialQuantityValue) {
Toast.makeText(getApplicationContext(),
"Short Of Quantity", Toast.LENGTH_SHORT)
.show();
} else {
strEnteredQuantity = etbillQuantity.getText()
.toString();
enteredQuantityValue = Double
.parseDouble(strEnteredQuantity);
tempproduct_TotalQuantity.add(tvInitialQuantity
.getText().toString());
newQuantityValue = initialQuantityValue
- enteredQuantityValue;
setQuantity.setText(strEnteredQuantity);
String setQuantityStr = "";
GlobalVariables.arrayOfTempProductSetQuantity
.add(strEnteredQuantity);
GlobalVariables.arrayOfTempProductName.add(tvName
.getText().toString());
GlobalVariables.arrayOfTempProductCode.add(tvCode
.getText().toString());
GlobalVariables.arrayOfTempProductUnitPrice
.add(tvPrice.getText().toString());
GlobalVariables.arrayOfTempProductQuantity
.add((String.valueOf(newQuantityValue)));
if (tempproduct_Code.size() <= 0) {
tempproduct_Code.add(tvCode.getText()
.toString());
tempproduct_Name.add(tvName.getText()
.toString());
tempproduct_Quantity.add(strEnteredQuantity);
tempproduct_UnitPrice.add(tvPrice.getText()
.toString());
}
else {
String setQuantityTemp = "";
String setUnitPriceTemp = "";
String setNameTemp = "";
String setCodeTemp = "";
for (int i = 0; i < (tempproduct_Code.size()); i++) {
for (int j = 0; j < (GlobalVariables.arrayOfTempProductCode
.size()); j++) {
if (tempproduct_Code
.get(i)
.contains(
GlobalVariables.arrayOfTempProductCode
.get(j))) {
setQuantityTemp = GlobalVariables.arrayOfTempProductSetQuantity
.get(j);
tempproduct_Quantity.set(i,
setQuantityTemp);
setCodeTemp = GlobalVariables.arrayOfTempProductCode
.get(j);
tempproduct_Code
.set(i, setCodeTemp);
setNameTemp = GlobalVariables.arrayOfTempProductName
.get(j);
tempproduct_Name
.set(i, setNameTemp);
setUnitPriceTemp = GlobalVariables.arrayOfTempProductUnitPrice
.get(j);
tempproduct_UnitPrice.set(i,
setUnitPriceTemp);
} else {
tempproduct_Code.add(tvCode
.getText().toString());
tempproduct_Name.add(tvName
.getText().toString());
tempproduct_Quantity
.add(strEnteredQuantity);
tempproduct_UnitPrice.add(tvPrice
.getText().toString());
}
}
}
}
InputMethodManager imm = (InputMethodManager) getSystemService(context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(
etbillQuantity.getWindowToken(), 0);
onSetQuantityDisplayData();
alertDialog.dismiss();
}
}
});
现在在日志中显示内存不足 我已经使用了列表视图性能优化的最佳方法 显示数组列表内存不足的日志 日志还显示了一段时间的增长堆应用程序是结构和崩溃

【问题讨论】：
-
@Skynet 完成请检查
-
第349行是什么，请在此标出？错误总是出现在这一行吗？
-
@Skynet tempproduct_Code.add(tvCode.getText().toString());不知道怎么标记请帮忙
-
你如何定义
tempproduct_Code -
@Skynet private ArrayList
tempproduct_Code = new ArrayList ();
