大小为arraylist的java内存泄漏
我有一个活动：
public void onCreate(Bundle savedInstanceState) {
time=(EditText) findViewById(R.id.time);
...
public void mass_func(){
...
double ttime=Double.parseDouble(time.getText().toString().trim());
double res=mass*(Math.pow(0.5,ttime/half_time));
....
//filling the array
int temp=(int) ttime;
ArrayList <MyDouble> final_mass=new ArrayList <MyDouble>(temp);//i want the size to be maximum as the ttime
for (int i=0;i<=temp;i++){
MyDouble m1=new MyDouble(mass*(Math.pow(0.5,i/half_time)));
final_mass.add(m1);
}
Intent i=new Intent(this,mass_calcs.class);
...
i.putExtra("time",ttime);
i.putParcelableArrayListExtra("final_mass",final_mass);
startActivity(i);
}
从mass_calcs活动中，我只将值传递给LineGraph活动。 线条图活动是：
public class LineGraph_mass extends Activity {
...
private Double ttime;
//ArrayList <MyDouble> final_mass=new ArrayList <MyDouble>(ttime.intValue());
ArrayList <MyDouble> final_mass=new ArrayList <MyDouble>( 10000);
问题在于，当用户输入的时间值约为“4000”时，应用程序崩溃。 我收到错误“GC\u FOR\u MALLOC freed…”这意味着内存泄漏
从我所做的阅读中，我看到了一种处理方法，那就是给arraylist一个大小
但在我的情况下，我怎么能做到这一点呢
我正在定义“ArrayList final_mass=新ArrayList（temp）；”在第一个活动中，尝试了类似“…==newArrayList（ttime.intValue（））；”的内容在线形图上，但它不起作用
（我也试过像“…==newarraylist（10000）”这样的东西，但它也不起作用

# 1 楼答案
首先，我建议不要创建一个10000个条目的ArrayList——这不是必需的
我对这个问题不是100%熟悉，但是如果您只有这么多的数据点，并且用户输入的内容很遥远，那么为什么不限制用户可以输入的内容呢？如果它不是一个有效的条目，请在Toast消息中告诉他们，并检查输入，使活动不会崩溃
ttime在您的线形图中有什么价值
# 2 楼答案
您不需要设置
ArrayList的大小-这基本上是使用ArrayList的优点之一。它是动态的。不要将它与常规Java数组混淆，在这里可以定义特定的大小
