android 自定义toast停留时间

Toast类

    //首先定义全局变量mToast已经显示和隐藏函数    private Toast mToast;    // 隐藏toast信息框常量    public static final int AIRPLAY_MESSAGE_HIDE_TOAST = 22;    // 显示toast信息框时间    public static final int AIRPLAY_TOAST_DISPLAY_TIME = 1000;    public void showShortToast(String text) {        if(mToast == null) {            mToast = Toast.makeText(AppContext.getInstance(), text, Toast.LENGTH_SHORT);        } else {            mToast.setText(text);            mToast.setDuration(Toast.LENGTH_SHORT);        }        mToast.show();    }    public void cancelToast() {        if (mToast != null) {            mToast.cancel();        }    }

调用

final Handler m_Handler = new Handler(){                    @Override                    public void handleMessage(Message msg) {                        super.handleMessage(msg);                        // TODO Auto-generated method stub                        switch (msg.what) {                            case 0:                                break;                            case BaseActivity.AIRPLAY_MESSAGE_HIDE_TOAST: {                                cancelToast();                                break;                            }                        }                    }                };      showShortToast(getString(R.string.error_tag_name_input));      Message delayMsg = m_Handler.obtainMessage(AIRPLAY_MESSAGE_HIDE_TOAST);      m_Handler.sendMessageDelayed(delayMsg, AIRPLAY_TOAST_DISPLAY_TIME);

private static final int LONG_DELAY = 3500; // 3.5 seconds

private static final int SHORT_DELAY = 2000; // 2 seconds

Toast.Long = 3.5s

Toast.short = 2.0s

Toast..makeText( Context context, CharSequence text, int duration) .show() 中的duration只能设这两个值，其他值是没有用的
