android開發：按鈕事件

關於按鈕事件，有很多種，參考：http://blog.sina.com.cn/s/blog_7013d1fe01014t3o.html

使用個簡單的：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="vertical"    android:layout_width="fill_parent"    android:layout_height="fill_parent"    ><TextView      android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:text="@string/hello"    /><TextView    android:id="@+id/textView1"    android:layout_width="222dp"    android:layout_height="wrap_content"    android:text="@string/hello"     android:textColor="@color/textcolor"/><Button    android:id="@+id/button1"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:text="@string/button1"     android:onClick="exitOnclick"/></LinearLayout>

 

<?xml version="1.0" encoding="utf-8"?><resources>    <string name="hello">Hello World, MainActivity!</string>    <string name="app_name">HelloWorld</string>    <color name="textcolor">#0000FF</color>    <string name="button1">點擊</string></resources>

 

public class MainActivity extends Activity {    private TextView mytextview;    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);    }        //Button myButton=(Button)findViewById(R.id.button1);    //myButton.setOnClickListener(){        //}        public void exitOnclick(View view)    {        //Intent intenttemp=new Intent();        //Toast toast=Toast.makeText(this, "顯示內容",Toast.LENGTH_LONG);        //toast.show();        mytextview=(TextView)findViewById(R.id.textView1);        String str="my name is langui";        mytextview.setText(str);    }}

注意：exitOnclick(View view) ，括弧裡的內容一定要

按鈕事件完成，的確和js有點相像。。。
