我使用游标查询获取所有手机号码。我已启用严格模式获取此异常。

以下是我提取手机号码的代码：

public String queryForPhoneNumber(String contactId) {
    final String[] projection = new String[] {
            Phone.NUMBER,
            Phone.TYPE,
    };

    final Cursor phone = getActivity().getContentResolver().query(
            Phone.CONTENT_URI,  
            projection,
            Data.DISPLAY_NAME + "=?",
            new String[]{contactId},
            null);

    if(phone.moveToFirst()) {
        final int contactNumberColumnIndex = phone.getColumnIndex(Phone.NUMBER);
        //final int contactTypeColumnIndex = phone.getColumnIndex(Phone.TYPE);

        while(!phone.isAfterLast()) {
            mFmFmUserMobile = phone.getString(contactNumberColumnIndex);
            //final int type = phone.getInt(contactTypeColumnIndex);
            phone.moveToNext();
        }

    }
    phone.close();

    if(mFmFmUserMobile.contains(" ")){
        mFmFmUserMobile.replace(" ", "");
    }
    //mFmFmUserMobile.substring(mFmFmUserMobile.length()-10,mFmFmUserMobile.length()

    return mFmFmUserMobile;
}

例外：

您不应该在UI线程上执行工作，而是创建工作线程并在那里完成大部分工作。最简单的解决方案是使用AsyncTask：

public class StrictModeActivity extends AppCompatActivity {

    private static final String TAG = StrictModeActivity.class.getSimpleName();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        StrictMode.setThreadPolicy(new StrictMode.ThreadPolicy.Builder()
                .detectDiskReads()
                .detectDiskWrites()
                .detectNetwork()
                .penaltyLog()
                .penaltyDeath()
                .build());

        new QueryForPhoneNumberTask().execute("your contact display name");
    }

    private class QueryForPhoneNumberTask extends AsyncTask<String, Void, String> {

        @Override
        protected String doInBackground(String... strings) {
            String mFmFmUserMobile = null;
            String contactId = strings[0];

            final String[] projection = new String[]{
                    ContactsContract.CommonDataKinds.Phone.NUMBER,
                    ContactsContract.CommonDataKinds.Phone.TYPE,
            };

            final Cursor phone = getContentResolver().query(
                    ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                    projection,
                    ContactsContract.Data.DISPLAY_NAME + "=?",
                    new String[]{contactId},
                    null);

            if (phone.moveToFirst()) {
                final int contactNumberColumnIndex = phone.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
                //final int contactTypeColumnIndex = phone.getColumnIndex(Phone.TYPE);

                while (!phone.isAfterLast()) {
                    mFmFmUserMobile = phone.getString(contactNumberColumnIndex);
                    //final int type = phone.getInt(contactTypeColumnIndex);
                    phone.moveToNext();
                }
            }
            phone.close();

            if (mFmFmUserMobile != null && mFmFmUserMobile.contains(" ")) {
                mFmFmUserMobile.replace(" ", "");
            }
            //mFmFmUserMobile.substring(mFmFmUserMobile.length()-10,mFmFmUserMobile.length()

            return mFmFmUserMobile;
        }

        @Override
        protected void onPostExecute(String result) {
            Log.d(TAG, result);
        }
    }
}
