我在一项活动中有这个：
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活动我只是将值传递给LineGraph活动。 LineGraph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);
问题是，当用户输入大约'4000'的时间值时，应用程序崩溃。 我收到错误“GC_FOR_MALLOC释放...”这意味着内存泄漏。
从我所做的阅读中，我看到一种方法可以让arraylist达到一定的规模。
但我怎么能在我的情况下这样做？
我正在定义“ArrayList final_mass = new ArrayList（temp）;”在第一个活动，并尝试像“... =新的ArrayList（ttime.intValue（））;”在LineGraph，但它不会工作。
（我也试过像“...... =新的ArrayList（10000）”但它也不起作用。

答案 0 :(得分：1)
您没有设置ArrayList的大小 - 这基本上是使用ArrayList的美女之一。这是动态的。不要将它与常规Java数组混淆，您可以在其中定义一定的大小。
答案 1 :(得分：0)
首先，我建议不要制作一个10,000条目ArrayList-这是不必要的。
我不是100％熟悉这个问题，但是如果你只有这么多的数据点，并且用户输入的东西很远，那么为什么不限制用户可以输入的内容呢？如果它不是有效条目，请在Toast消息中告诉它们，并检查输入以使活动不会崩溃。
ttime在LineGraph_mass活动中有什么价值？
