快速掌握Android三個常用自定義控件Toast AlertDialog Notification

網上相關自定義方法很多，總結整理了下安卓自定義Toast  AlertDialog  Notification：

Toast toast;

 

public void myToast(Context context,String text){
		if(toast==null){
		toast=Toast.makeText(context, text, Toast.LENGTH_SHORT);//或自定義Toast toast=new Toast(this);toast.setView(view);
		toast.show();
		}else{
		toast.setText(text); 
		toast.show();
		}
    }

 

AlertDialog   設置系統級dialog: setType(LayoutParams.TYPE_SYSTEM_ALERT);//建議type=2002

 

public void myAlertDialog(){
       View view=getLayoutInflater().inflate(R.layout.dialog,null);//dialog自定義佈局
       AlertDialog dialog = new AlertDialog.Builder(this).show();
       Window window = dialog.getWindow();
       WindowManager.LayoutParams attributes = window.getAttributes();
       attributes.width=WindowManager.LayoutParams.MATCH_PARENT;//無間距鋪滿
       window.setAttributes(attributes);
       window.setBackgroundDrawableResource(android.R.color.transparent);//背景透明鋪滿
       window.setGravity(Gravity.BOTTOM);
       window.setContentView(view);
       window.clearFlags(WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);//允許輸入法
  /*隱藏輸入法:1.android:windowSoftInputMode="adjustResize|stateAlwaysHidden" 
  *           2.inputMethodManager.hideSoftInputFromWindow(edittext.getWindowToken(),0);
  * 切換輸入法:((InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE)).toggleSoftInput(0,0);
  */    
}

 

Notification

 

public void myNotification(){
       NotificationManager nm = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);

       RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.custom);

       PendingIntent intent = PendingIntent.getActivity(context, 0, intent2, 0);

       Notification notification = new Notification();
                notification.icon =R.drawable.ic_launcher;//圖標
                notification.tickerText = "通知";//標題
                notification.when=System.currentTimeMillis();
                notification.defaults=Notification.DEFAULT_SOUND;
                notification.contentView = views;//通知自定義佈局 setLatestEventInfo默認
                notification.flags=Notification.FLAG_NO_CLEAR;//點擊不消失;
                notification.contentIntent = intent;//點擊意圖不能null

                nm.notify(1, notification);
  }

 

//注意：RemoteViews不支持SeekBar  只支持類標識了@RemoteView的控件
