我正在使用一种名单法,这扔下了Null Pointer例外。
private ContextWrapper ctx;
return ctx.getContentResolver().query(
Data.CONTENT_URI,
new String[] {
Data.DATA1
},
Data.RAW_CONTACT_ID + "=" + this.getId() + " AND " + Data.MIMETYPE + "= " + mimetype

Data.CONTENT_URI,
new String[] {
Data.DATA1
},
Data.RAW_CONTACT_ID + "=" + this.getId() + " AND " + Data.MIMETYPE + "= " + mimetype
+ " ", null, null);
