安卓如何读取联系人不加read_contacts和write_contacts，会有以下的报错

12-10 11:14:42.971 1079-1107/? W/ActivityManager: Permission Denial: opening provider com.android.providers.contacts.ContactsProvider2 from ProcessRecord{b2377c8 14473:com.pic.optimize/u0a212} (pid=14473, uid=10212) requires android.permission.READ_CONTACTS or android.permission.WRITE_CONTACTS

我们打算做一个下面的界面:

xml文件是:

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:rcm="http://schemas.android.com/apk/res/com.ringcentral.android"

android:id="@+id/contact_list_view"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:background="@color/bgColorMain"

android:orientation="vertical" >

<FrameLayout

android:layout_width="match_parent"

android:layout_height="match_parent" >

<ListView

android:id="@android:id/list"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:cacheColorHint="@android:color/transparent"

android:divider="@null"

android:listSelector="@drawable/bg_list_item_selector" />

<com.example.view.SectionIndexerView

android:layout_width="70dip"

android:layout_height="fill_parent"

android:layout_gravity="right"

android:layout_marginBottom="4dip"

android:layout_marginRight="6dip"

android:layout_marginTop="4dip"

android:textSize="12.0sp" />

<TextView

android:layout_height="wrap_content"

android:layout_gravity="center"

android:background="@drawable/section_text_bg"

android:gravity="center"

android:textColor="#FFFFFF"

android:textSize="40sp"

android:visibility="gone" />

</FrameLayout>

<RelativeLayout

android:id="@+id/no_contact_indication"

android:layout_width="match_parent"

android:layout_height="match_parent" >

<TextView

android:id="@+id/emptyListText"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_centerInParent="true"

android:singleLine="true"

android:text="No Contacts"

android:textColor="@color/text_no_items"

android:textSize="20sp" />

<ProgressBar

android:id="@+id/loading"

style="@style/RCMProgressBar"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_centerInParent="true"

android:visibility="gone" />

</RelativeLayout>

</LinearLayout>

android提供了本地数据库的查询uri,可以查询出数据:

采用一个AsyncQueryHandler来进行查询, AsyncQueryHandler自己开启了线程来进行数据查询，很方便

protected final void queryPersonal() {

mQueryHandler.startQuery(QUERY_TOKEN, null, ContactsContract.Contacts.CONTENT_URI,

Personal.CONTACTS_SUMMARY_PROJECTION, null, null, getSortOrder(ContactsContract.Contacts.DISPLAY_NAME));

}

protected static String getSortOrder(String fieldName) {

return "CASE WHEN substr(UPPER(" + fieldName + "), 1, 1) BETWEEN 'A' AND 'Z' THEN 1 else 10 END," +

fieldName + " COLLATE LOCALIZED ASC";

}

protected final class MyHandler extends AsyncQueryHandler {

/**

* Asynchronous query handler constructor.

*/

public MyHandler(Context context) {

super(context.getContentResolver());

}

/**

* On query completion.

*/

@Override

protected void onQueryComplete(int token, Object cookie, Cursor cursor) {

if (cursor == null || cursor.isClosed()) {

return;

}

if (!isFinishing()) {

setLoading(false);

if (mAdapter != null) {

mAdapter.setLoading(false);

mAdapter.changeCursor(cursor);

}

if (cursor.getCount() == 0) {

mEmtytext.setVisibility(View.VISIBLE);

} else {

mEmtytext.setVisibility(View.INVISIBLE);

}

} else {

if (cursor != null && !cursor.isClosed()) {

cursor.close();

}

List的adapter采用ResourceCursorAdapter

public void bindView(View view, Context context, Cursor cursor) {

final SectionedContactListItemCache cache = (SectionedContactListItemCache) view.getTag();

cache.typeView.setVisibility(View.GONE);

cache.photoView.setVisibility(View.VISIBLE);

String name = cursor.getString(Personal.NAME_COLUMN_INDEX);

if (TextUtils.isEmpty(name)) {

cache.nameView.setText(R.string.contact_no_name);

} else {

cache.nameView.setText(name);

}

if(mSectionMapper != null && mSectionMapper.isSection(cursor.getPosition())) {

cache.sectionHeader.setVisibility(View.VISIBLE);

cache.sectionHeader.setText(mSectionMapper.getSection(cursor.getPosition()));

// Set section header unclickable

cache.sectionHeader.setOnClickListener(null);

}else{

cache.sectionHeader.setVisibility(View.GONE);

}

setContactPhoto(cursor, cache.photoView, Personal.PHOTO_COLUMN_INDEX);

}

@Override

public View newView(Context context, Cursor cursor, ViewGroup parent) {

View view = super.newView(context, cursor, parent);

final SectionedContactListItemCache cache = new SectionedContactListItemCache();

cache.nameTypeWrapper = view.findViewById(R.id.name_type);

cache.sectionHeader = (TextView) view.findViewById(R.id.txtSectionHeader);

cache.nameView = (TextView) view.findViewById(R.id.name);

cache.typeView = (TextView) view.findViewById(R.id.type);

cache.photoView = (ImageView) view.findViewById(R.id.photo);

cache.detailItemIcon = (ImageView) view.findViewById(R.id.contacts_detail_item_icon);

view.setTag(cache);

return view;

}

Item的layout:
