Mono自定义图片按钮_移动开发_编程开发_程序员俱乐部

首先，我们编写一个MyImageButton类，继承自LinearLayout

class="code_img_closed" src="/Upload/Images/2014071509/0015B68B3C38AA5B.gif" alt="" />logs_code_hide('0cbaf35e-a9e3-40e9-bb9d-701db4dd9708',event)" src="/Upload/Images/2014071509/2B1B950FA3DF188F.gif" alt="" />

public class MyPhoneImageButton:LinearLayout
    {
        private ImageView mButtonImage = null; 
        private TextView mButtonText = null; 
    
        public MyPhoneImageButton (Context context) :
            base (context)
        {
            mButtonImage = new ImageView(context); 
            mButtonText = new TextView(context); 
        
            mButtonImage.SetPadding(0, 0, 0, 0); 
            mButtonText.SetPadding(0, 0, 0, 0); 
                //设置本布局的属性 
            Clickable = true;
            Focusable = true;
            AddView (mButtonText);
            AddView (mButtonImage);
        
        }
        public void setImageResource(int resId) { 
            mButtonImage.SetImageResource(resId); 
        } 
        public void setText(string resId) { 
            mButtonText.Text=resId; 
        } 
        public void setTextColor(int color) { 
            mButtonText.SetTextColor(Resources.GetColor (color)); 
        } 


    }

View Code

然后在main布局中为我们自定义的Button写xml布局，注意，我们的“按钮”实际上是一个线性布局，因此xml中应该写LinearLayout而不是Button或者ImageButton

 

  <LinearLayout
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:id="@+id/tvPPhone"
                android:orientation="horizontal" />

View Code

 

最后，在Activity中为我们自定义的按钮设置监听

 

        private LinearLayout llbtDataConfig = null;  //main布局中包裹本按钮的容器 
        private MyPhoneImageButton btDataConfig = null; 
btDataConfig = new MyPhoneImageButton (this);
            btDataConfig.setTextColor (Resource.Color.text_color_projectInfo);
            btDataConfig.setText ("我是文字");
            btDataConfig.setImageResource (Resource.Drawable.phone);
            llbtDataConfig=FindViewById<LinearLayout> (Resource.Id.tvPPhone);
            llbtDataConfig.AddView(btDataConfig); 

            llbtDataConfig.SetOnClickListener (new llbtDataConfig_Click());

    //监听事件继承
        public class llbtDataConfig_Click : Java.Lang.Object, View.IOnClickListener  
        {  
            public void OnClick(View v)  
            {  


            }  
        }

View Code

 

另外发现监听不如点击事件好用。

            llbtDataConfig.Click += (object sender, EventArgs e) => {
                llbtDataConfig_Click ();
            };
