Android-1-電話撥號器

--重點提要--Android--R中的界面中關於添加控件的設計
        android:id="@+id/button1"---在R文件中添加ID號 
        findViewById(R.id.editText1);---尋找ID對應的空間
--重點提要--Android--啟動控件中的界面中關於添加控件的設計
//意圖：想干一件事==windows start
   Intent intent = new Intent();
//判斷輸入的內容是否為空
if(TextUtils.isEmpty(nummberstr)){
   
   }
----------------------------
android單擊事件的寫法
1.創建一個內部類實現OnClickListener接口
    重寫onClick()方法
2.實例化接口 ,匿名內部類
    bt_dail.setonClickListener( new OnClickListener(){
            CallPhone();
    })
3.MainActivity實現接口
    在類中重寫onClick()方法執行CallPhone()
    public void onClick(View v){
        switch( v.getId ){
            case R.id.bt_cail:
                ....;break;
            default :
                .....break;
        }
    }
 4.內部通過反射機制執行程序
android:onClick = "dailButtonClicked"
在MainActivity主程序中加入方法
執行程序
