android开发:按钮事件

关于按钮事件,有很多种,参考:http://blog.sina.com.cn/s/blog_7013d1fe01014t3o.html

使用个简单的:

<?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">点击</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, "显示内容",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) ,括弧里的内容一定要

按钮事件完成,的确和js有点相像。。。
