先生,我如何使用baseadapter刷新我的自定义列表视图.我不知道放置什么,或者将它放在我的代码中.请帮我.提前致谢
public class EditDetails extends Activity{
public String nameChanged;
public String numChanged;
public String name;
public String num;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.editdetails);
final EditText sqlName = (EditText)findViewById(R.id.editName);
final EditText sqlNumber = (EditText)findViewById(R.id.editNumber);
name = CustomListView.name;
num = CustomListView.number;
Button bUpdate = (Button)findViewById(R.id.editUpdate);
Button bView = (Button)findViewById(R.id.editView);
sqlName.setText(name);
sqlNumber.setText(num);
bUpdate.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
nameChanged = sqlName.getText().toString();
numChanged = sqlNumber.getText().toString();
GroupDb info = new GroupDb(EditDetails.this);
info.open();
long rowid = info.getRowId(name, num);
info.updateNameNumber(rowid, nameChanged, numChanged);
ArrayList<Contact> …即使在静音模式下如何启动声音？我的原始文件夹中有我的音频文件.我已经制作了一些代码但是当我进入android的声音设置时,铃声和闹钟是唯一被改为最大但不是媒体部分的.这是我的代码
public void playSound(Context context)
{
AudioManager audioManager = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE);
int maxVolumeAlarm = audioManager.getStreamMaxVolume(AudioManager.STREAM_ALARM);
int maxVolumeRing = audioManager.getStreamMaxVolume(AudioManager.STREAM_RING);
audioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
audioManager.setStreamVolume(AudioManager.STREAM_ALARM, maxVolumeAlarm,AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
audioManager.setStreamVolume(AudioManager.STREAM_RING, maxVolumeRing,AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);;
MediaPlayer mMediaPlayer;
mMediaPlayer = new MediaPlayer();
mMediaPlayer = MediaPlayer.create(context, R.raw.puff);
mMediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mMediaPlayer.setLooping(false);
mMediaPlayer.start();
}
先生,我如何根据输入名称,数字返回数据库的rowid？此代码每次都返回值0.我的主键是KEY_ROWID.提前感谢您的帮助
//get rowid
public long getRowId(String name, String number)
{
// TODO Auto-generated method stub
String[] columns = new String[]{KEY_ROWID, KEY_NAME, KEY_NUMBER};
Cursor c = ourDatabase.query(DATABASE_TABLE, columns, KEY_NUMBER+ "=" +number, null, null, null, null);
long rowid = c.getColumnIndex(KEY_ROWID);
return rowid;
}
这是我如何访问它
public void onClick(View arg0) {
nameChanged = sqlName.getText().toString();
numChanged = sqlNumber.getText().toString();
GroupDb info = new GroupDb(EditDetails.this);
info.open();
long rowid = info.getRowId(name, num);
info.updateNameNumber(rowid, nameChanged, numChanged);
Toast.makeText(getApplicationContext(), rowid+" "+nameChanged+" "+numChanged, Toast.LENGTH_LONG).show();
ArrayList<Contact> searchResults = info.getView();
MyCustomBaseAdapter mcba = new …先生，即使铃声静音也可以响铃吗？如果是，如何。而且，我可以将其音量设置为介于两者之间，而不仅仅是最大音量吗？提前致谢
for (SmsMessage msg : messages) {
if (msg.getMessageBody().contains("firealert")) {
Uri alert = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);

if(alert == null){
// alert backup is null, using 2nd backup
alert = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_RINGTONE);
}
}
Ringtone r = RingtoneManager.getRingtone(context.getApplicationContext(), alert);
AudioManager audioManager = (AudioManager)context.getSystemService(Context.AUDIO_SERVICE);
int maxVolumeAlarm = audioManager.getStreamMaxVolume(AudioManager.STREAM_ALARM);
int maxVolumeRing = audioManager.getStreamMaxVolume(AudioManager.STREAM_RING);
audioManager.setStreamVolume(AudioManager.STREAM_ALARM, maxVolumeAlarm,AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
audioManager.setStreamVolume(AudioManager.STREAM_RING, maxVolumeRing,AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
r.play();
Toast.makeText(context.getApplicationContext(), "alarm started", Toast.LENGTH_LONG).show();
}//end if
}//end for
