Android Activity为对话框黑色边框

Question

我有对话活动，我喜欢的所有节目。但我对它们周围的框架有问题。就像这里一样。

我的活动：

public class AlarmAlert extends Activity implements Alarms.AlarmSettings {



    @Override
        protected void onCreate(Bundle icicle) {
            super.onCreate(icicle);

            AlarmAlertWakeLock.acquire(this);

            /*
             * FIXME Intentionally verbose: always log this until we've fully
             * debugged the app failing to start up
             */
            Log.v("AlarmAlert.onCreate()");
            DigitalClock dc = (DigitalClock) findViewById(R.id.digitalClock1);

            mKeyguardManager = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);

            Intent i = getIntent();
            mAlarmId = i.getIntExtra(Alarms.ID, -1);

            Alarms.getAlarm(getContentResolver(), this, mAlarmId);

            mKlaxon = new AlarmKlaxon();
            mKlaxon.postPlay(this, mAlarmId);

            /* Set the title from the passed in label */
            setTitleFromIntent(i);

            /*
             * allow next alarm to trigger while this activity is active
             */
            Alarms.disableSnoozeAlert(AlarmAlert.this);
            Alarms.disableAlert(AlarmAlert.this, mAlarmId);
            Alarms.setNextAlert(this);

            mKlaxon.setKillerCallback(new AlarmKlaxon.KillerCallback() {
                public void onKilled() {
                    if (Log.LOGV)
                        Log.v("onKilled()");
                    updateSilencedText();

                    /* don't allow snooze */
                    mSnoozeButton.setEnabled(false);
                    dismiss();
                    mState = KILLED;
                }
            });

            updateLayout();

            SharedPreferences settings = getSharedPreferences(
                    AlarmClock.PREFERENCES, 0);
            if (settings.getBoolean(AlarmClock.PREF_SHAKE_SNOOZE, true)) {
                mShakeListener = new ShakeListener(this);
                mShakeListener
                        .setOnShakeListener(new ShakeListener.OnShakeListener() {
                            public void onShake() {
                                snooze();
                                if (mCaptchaSnooze == 0)
                                    finish();
                            }
                        });
            }
        }

        private void setTitleFromIntent(Intent i) {
            mLabel = i.getStringExtra(Alarms.LABEL);
            if (mLabel == null || mLabel.length() == 0) {
                mLabel = getString(R.string.default_label);
            }
            setTitle(mLabel);
        }

        private void updateSilencedText() {
            TextView silenced = (TextView) findViewById(R.id.silencedText);
            silenced.setText(getString(R.string.alarm_alert_alert_silenced,
                    mDuration / 1000 * 60));
            silenced.setVisibility(View.VISIBLE);
        }

        private void updateLayout() {
            setContentView(R.layout.alarm_alert);
