我創建了一個實現可執行程序接口的類。然後我創建了該類的數組列表，並將其意圖傳遞給另一個活動。但是，當活動嘗試獲取parcelable數組列表中運行時異常happpening可執行程序對象不能正常工作的列表
我parcelable類是
package com.myapps.sulu.firstapp;
import android.os.Parcel;
import android.os.Parcelable;
public class Details implements Parcelable {
int id = 0;
String name = "";
int number = 0;
public Details(int id, String name, int number) {
this.id = id;
this.name = name;
this.number = number;
}
public Details(Parcel in) {
this.id = in.readInt();
this.name = in.readString();
this.number = in.readInt();
}
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeInt(id);
dest.writeInt(number);
dest.writeString(name);
}
public int getId() {
return id;
}
public String getName() {
return name;
}
public int getNumber() {
return number;
}
public static final Creator<Details> CREATOR = new Creator<Details>() {
@Override
public Details createFromParcel(Parcel in) {
return new Details(in);
}
@Override
public Details[] newArray(int size) {
return new Details[size];
}
};
}
我在這裏創建數組列表
Cursor cursor = writableDatabase.query(TestContracts.TestTable.TABLE_NAME, projection,
null, null, null, null, null);
cursor.moveToFirst();
ArrayList<Details> allDetailses = new ArrayList<Details>();
do {
int id = cursor.getInt(cursor.getColumnIndex(TestContracts.TestTable.ID));
int phone_number = cursor.getInt(cursor.getColumnIndex(TestContracts.TestTable.NUMBER));
String name = cursor.getString(cursor.getColumnIndex(TestContracts.TestTable.NAME));
Details details = new Details(id, name, phone_number);
Log.d("MSG", name + " " + id + " " + phone_number);
allDetailses.add(details);
} while (cursor.moveToNext());
Intent intent = new Intent(DbActivity.this, DetailsActivity.class);
intent.putParcelableArrayListExtra("values", allDetailses);
startActivity(intent);
我得到了例外getParcalableArrayList行如下所示
Intent intent = getIntent();
values = intent.getParcelableArrayListExtra("values");
showRows();

是否要將整個遊標數據添加到Intent的額外？它真的是你想要做的嗎？ – pskink
是的，要在另一個活動 –
中顯示錶格，然後傳遞信息「如何」獲取光標，不傳遞所有數據，如果您有成千上萬的行，那該怎麼辦？ – pskink
