如何通過意圖傳遞View的對象？

-1

我試圖通過Parceable實現我的POJO類。但在向View的對象寫入值時顯示錯誤。如何通過意圖傳遞View的對象？

POJO類：在dest.writeValue（視圖）所示

import android.os.Parcel; 
import android.os.Parcelable; 
import android.view.View; 
import android.widget.EditText; 


public class FieldData implements Parcelable { 
private Integer id; 
private String value; 
private Integer job_transaction_id; 
private Integer field_attribute_master_id; 
private Boolean required; 
private View view; 
private String viewType; 

public Integer getId() { 
    return id; 
} 

public void setId(Integer id) { 
    this.id = id; 
} 

public String getValue() { 
    return value; 
} 

public void setValue(String value) { 
    this.value = value; 
} 

public Integer getJob_transaction_id() { 
    return job_transaction_id; 
} 

public void setJob_transaction_id(Integer job_transaction_id) { 
    this.job_transaction_id = job_transaction_id; 
} 

public Integer getField_attribute_master_id() { 
    return field_attribute_master_id; 
} 

public void setField_attribute_master_id(Integer field_attribute_master_id) { 
    this.field_attribute_master_id = field_attribute_master_id; 
} 

public Boolean getRequired() { 
    return required; 
} 

public void setRequired(Boolean required) { 
    this.required = required; 
} 

public View getView() { 
    return view; 
} 

public void setView(View view) { 
    this.view = view; 
} 

public String getViewType() { 
    return viewType; 
} 

public void setViewType(String viewType) { 
    this.viewType = viewType; 
} 



protected FieldData(Parcel in) { 
    id = in.readByte() == 0x00 ? null : in.readInt(); 
    value = in.readString(); 
    job_transaction_id = in.readByte() == 0x00 ? null : in.readInt(); 
    field_attribute_master_id = in.readByte() == 0x00 ? null : in.readInt(); 
    byte requiredVal = in.readByte(); 
    required = requiredVal == 0x02 ? null : requiredVal != 0x00; 
    view = (View) in.readValue(View.class.getClassLoader()); 
    viewType = in.readString(); 
} 

public FieldData() { 
    // TODO Auto-generated constructor stub 
} 

@Override 
public int describeContents() { 
    return 0; 
} 

@Override 
public void writeToParcel(Parcel dest, int flags) { 
    if (id == null) { 
     dest.writeByte((byte) (0x00)); 
    } else { 
     dest.writeByte((byte) (0x01)); 
     dest.writeInt(id); 
    } 
    dest.writeString(value); 
    if (job_transaction_id == null) { 
     dest.writeByte((byte) (0x00)); 
    } else { 
     dest.writeByte((byte) (0x01)); 
     dest.writeInt(job_transaction_id); 
    } 
    if (field_attribute_master_id == null) { 
     dest.writeByte((byte) (0x00)); 
    } else { 
     dest.writeByte((byte) (0x01)); 
     dest.writeInt(field_attribute_master_id); 
    } 
    if (required == null) { 
     dest.writeByte((byte) (0x02)); 
    } else { 
     dest.writeByte((byte) (required ? 0x01 : 0x00)); 
    } 
    **dest.writeValue(view);**//Error at this line 
    dest.writeString(viewType); 
} 

@SuppressWarnings("unused") 
public static final Parcelable.Creator<FieldData> CREATOR = new Parcelable.Creator<FieldData>()  { 
    @Override 
    public FieldData createFromParcel(Parcel in) { 
     return new FieldData(in); 
    } 

    @Override 
    public FieldData[] newArray(int size) { 
     return new FieldData[size]; 
    } 
};

}

誤差;

嘗試傳遞EditText而不是EditText，而這在android中是不可能的。 – 2014-11-08 13:10:16

View不parcelable。

理想情況下，您可以在第二個活動中創建類似的視圖。必需的attibutes可以從第一個活動傳遞到第二個活動

通過在pojo類中實現Serializable接口使其可序列化。然後你可以把Serializable放在Bundle中。

public final class SavingsAccount implements Serializable { 
{ 

}
