我在下面的代码中遇到异常

和我的 ContentPickerTester.java

的源代码

startActivityForResult(intent, PICK_CONTACT);

package com.example.contactpicker;

import android.app.Activity;
import android.content.Intent;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.provider.Contacts.People;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;

public class ContentPickerTester extends Activity {

  public static final int PICK_CONTACT = 1;

  @Override
  public void onCreate(Bundle icicle) {
    super.onCreate(icicle);
    setContentView(R.layout.contentpickertester);

    Button button = (Button)findViewById(R.id.pick_contact_button);

    button.setOnClickListener(new OnClickListener() {
     public void onClick(View _view) {
        Intent intent = new Intent(Intent.ACTION_PICK,
                                   Uri.parse("content://contacts/"));
        startActivityForResult(intent, PICK_CONTACT); 
      }
    });
  }

  @Override
  public void onActivityResult(int reqCode, int resCode, Intent data) {
    super.onActivityResult(reqCode, resCode, data);

    switch(reqCode) {
      case (PICK_CONTACT) : {
        if (resCode == Activity.RESULT_OK) {
          Uri contactData = data.getData();
          Cursor c = managedQuery(contactData, null, null, null, null);
          c.moveToFirst();
          String name = c.getString(c.getColumnIndexOrThrow(People.NAME));
          TextView tv = (TextView)findViewById(R.id.selected_contact_textview);
          tv.setText(name);
        }
        break;
      }
    }
  }
}

我在下面的代码中遇到异常

Answer 1

试试下面的代码：

Intent intent = new Intent(Intent.ACTION_PICK, ContactsContract.Contacts.CONTENT_URI);  
startActivityForResult(intent, 1);  

// ...

@Override  
public void onActivityResult(int reqCode, int resultCode, Intent data) {  
    super.onActivityResult(reqCode, resultCode, data);  
    if (resultCode == Activity.RESULT_OK) {  
        Uri contactData = data.getData();  
        Cursor c =  managedQuery(contactData, null, null, null, null);  
        if (c.moveToFirst()) {  
            String name = c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts.DISPLAY_NAME));  
           TextView tv = (TextView)findViewById(R.id.selected_contact_textview);
      tv.setText(name);
        }  
    }  
}

Answer 2

你可以通过这种方式传递intent。

Intent intent = new Intent(Intent.ACTION_PICK,ContactsContract.Contacts.CONTENT_URI);
        startActivityForResult(intent, 0);

public void onActivityResult(int reqCode, int resultCode, Intent data) {
        super.onActivityResult(reqCode, resultCode, data);
        if (i == reqCode && resultCode == Activity.RESULT_OK) {
            Cursor c = managedQuery(contactData, null, null, null, null);
                    if (c.moveToFirst()) {
                        String id = c.getString(c.getColumnIndexOrThrow(ContactsContract.Contacts._ID));
                        String hasPhone = c.getString(c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));

                        if (hasPhone.equalsIgnoreCase("1")) {
                            Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                                            null,
                                            ContactsContract.CommonDataKinds.Phone.CONTACT_ID
                                                    + " = " + id, null, null);
                            phones.moveToFirst();
                            cNumber = phones.getString(phones.getColumnIndex("data1"));
                            name=phones.getString(phones.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));
                            System.out.println("NAME:"+name+"\n NUMBER:"+cNumber);

                    }
                    }
           }
        }

这很好用，我一直在用这个。
