Mono自定义图片按钮

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

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 ();

            };
