contactmanager.xml如下：

The contactmanager.xml as below:

package com.example.android.contactmanager;

        // Obtain handles to UI objects
        mAddAccountButton = (Button) findViewById(R.id.addContactButton);

            }
        });
        mShowInvisibleControl.setOnCheckedChangeListener(new OnCheckedChangeListener() {

                populateContactList();
            }
        });

        // Populate the contact list
        populateContactList();
    }

    /**

    }

    /**
     * Obtains the contact list for the currently selected account.
     *

        Uri uri = ContactsContract.Contacts.CONTENT_URI;
        String[] projection = new String[] {

                ContactsContract.Contacts.DISPLAY_NAME
        };
        String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = '" + (mShowInvisible ? "0" : "1") + "'";
        //String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = '" + (mShowInvisible.get() ? "0" : "1") + "'";
        String[] selectionArgs = null;
        String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";

        return this.managedQuery(uri, projection, selection, selectionArgs, sortOrder);
    }

    /**

推荐答案

设置此属性 android： textView =10dip将Textview转换为contact_entry.xml，它将解决您的问题。

Set this property android:textSize="10dip" of Textview into contact_entry.xml, it will solve your problem.
