Dialog 的用法

private void showDialog(final String str,final CharSequence charSequence,final CharSequence charSequence2) {
new AlertDialog.Builder(this)
.setTitle(getResources().getString(R.string.caozuo_contact))
.setPositiveButton(
getResources().getString(
R.string.edit_contact_delete),
new DialogInterface.OnClickListener() {


@Override
public void onClick(DialogInterface dialog,
int which) {
// TODO Auto-generated method stub
dialog.dismiss();
Log.i("mylog", "aaaaaaaaaaaaa");
getContentResolver().delete(  
               ContentUris.withAppendedId(RawContacts.CONTENT_URI,  
                       Long.parseLong(str)), null, null);
}
})
.setNegativeButton(
getResources().getString(
R.string.edit_contact_edit_title),
new DialogInterface.OnClickListener() {


@Override
public void onClick(DialogInterface dialog,
int which) {
// TODO Auto-generated method stub
dialog.dismiss();
Intent intentb = new Intent(ContactActivity.this,
CalllogEditcontact.class);
intentb.putExtra("name", charSequence);

intentb.putExtra("number",charSequence2);
intentb.putExtra("RawId", str);
startActivity(intentb);
finish();
// intent.setDataAndType(
// MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
// "image/*");
// startActivityForResult(intent,
// PHOTO_REQUEST_GALLERY);
}
}).show();
}
