android – 如何以编程方式将图片(位图)分配给联系人？

你必须为那些创建自己的mime类型. @H_404_11@

@H_404_11@这是一个将布尔值作为我的自定义mime类型保存到联系人的示例.它使用最新的SDK 2.1

@H_404_11@重要

@H_404_11@此示例将DATA1用于数据,DATA1已编制索引,但不建议二进制数据.
在您的情况下,要存储二进制数据,如图片,您必须使用DATA15.

@H_404_11@按照惯例,DATA15用于存储BLOB(二进制数据).

public static final String MIMETYPE_FORMALITY = "vnd.android.cursor.item/useformality";
public clsMyClass saveFormality() {
        try {
            ContentValues values = new ContentValues();
            values.put(Data.DATA1,this.getFormality() ? "1" : "0");
            int mod = ctx.getContentResolver().update(
                    Data.CONTENT_URI,values,Data.CONTACT_ID + "=" + this.getId() + " AND "

                c.close();
            }

    data.remove(FORMALITY);
    data.put(FORMALITY,value);
    return this;

@H_404_11@用法是

@H_404_11@

objContact.setFormality(true).saveFormality();
