java.lang.ArrayIndexOutOfBoundsException : length=1; index=1 at forloop

Question

我试图在我的 Activity 中膨胀一个 xml，但我在 for 循环中收到这个 Arrayoutofbondception，因为它进入循环我不知道为什么它给我这个光标错误有人可以帮忙吗？

public class ProfleList extends AppCompatActivity {
    private TextView txtProfileName,txtProfileDate,txtProfileTime,txtProfileLocation;
    LinearLayout linearlist ;

    DatabaseHelper mydb;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_profle_list);

        mydb = new DatabaseHelper(this);

        long count = mydb.getCount();
        Log.d("count", "onCreate: "+count);

        if (count == 0){

        }else{
            ArrayList<ItemProfile> listprofile = mydb.profilelist();
            for (int i = 1; i < count; i++ ) {
                ItemProfile itemProfile = listprofile.get(i);

                linearlist = (LinearLayout)findViewById(R.id.layoutlist);
                View[] myView = new View[i];

                LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                myView[i] = inflater.inflate(R.layout.profile_list, null);

                txtProfileName = (TextView)myView[i].findViewById(R.id.txtName);
                txtProfileDate = (TextView)myView[i].findViewById(R.id.txtDate);
                txtProfileTime = (TextView)myView[i].findViewById(R.id.txtTime);
                txtProfileLocation = (TextView)myView[i].findViewById(R.id.txtLocation);

                txtProfileName.setText(itemProfile.getProfileName());
                txtProfileDate.setText(itemProfile.getDay()+itemProfile.getMonth()+itemProfile.getYear());
                txtProfileTime.setText(itemProfile.getHour()+itemProfile.getMinute());
                txtProfileLocation.setText(itemProfile.getCity());
                linearlist.addView(myView[i]);


            }



        }




    }

}

Answer 1

您的错误在这里:

View[] myView = new View[i];
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
myView[i] = inflater.inflate(R.layout.profile_list, null);

你已经定义了一个包含n个元素的 View 数组，那么你不能尝试在索引n处写入......

尝试在 0 到 n-1 之间

示例:

由于您是从 1 而不是 0 开始循环，因此使用 i-1 而不是 i

for (int i = 1; i < count; i++ ) {
...
View[] myView = new View[i];
LayoutInflater inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
myView[i-1] = inflater.inflate(R.layout.profile_list, null);
