在另一个活动中传递数组列表时出错

Question

这是我的申报单

List lstProfilePicture = new ArrayList（）;

这是我调用另一个活动的代码

Intent I = new Intent(logo activity . this，menu activity . class)；

i.putExtra（“Profile”， （Serializable） lstProfilePicture）;

这是我的个人资料课

公共类配置文件实现可序列化{

private Long employeeCode;
private Bitmap employeePicture;

public Profile() {
}

public Profile(Long employeeCode, Bitmap employeePicture) {
    this.employeeCode = employeeCode;
    this.employeePicture = employeePicture;
}

public Long getEmployeeCode() {
    return employeeCode;
}
public void setEmployeeCode(Long employeeCode) {
    this.employeeCode = employeeCode;
}
public Bitmap getEmployeePicture() {
    return employeePicture;
}
public void setEmployeePicture(Bitmap employeePicture) {
    this.employeePicture = employeePicture;
}

}

这是我的错误信息

/AndroidRuntime：致命异常：主进程：oras.liv.com。在oras中，PID:21484 java.lang.RuntimeException:Parcelable在写入可序列化对象时遇到IOException

如何在课堂上用位图通过？还有别的方法吗？

Answer 1

将其转换为字节数组

活动1:

try {
    //Write file
    String filename = "bitmap.png";
    FileOutputStream stream = this.openFileOutput(filename, Context.MODE_PRIVATE);
    bmp.compress(Bitmap.CompressFormat.PNG, 100, stream);

    //Cleanup
    stream.close();
    bmp.recycle();

    //Pop intent
    Intent in1 = new Intent(this, Activity2.class);
    in1.putExtra("image", filename);
    startActivity(in1);
} catch (Exception e) {
    e.printStackTrace();
}

在活动 2 中，加载位图：

Bitmap bmp = null;
String filename = getIntent().getStringExtra("image");
try {
    FileInputStream is = this.openFileInput(filename);
    bmp = BitmapFactory.decodeStream(is);
    is.close();
} catch (Exception e) {
    e.printStackTrace();
}
