我想让我的布局可点击,我觉得这很容易,但我偶然发现了一些问题。这是我的xml代码:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#0D47A1"
android:id="@+id/mylayout"
android:clickable="true"
android:onClick="layout">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:text="sometext"/>
</RelativeLayout>
和Java代码:
public void layout (View view){
Intent myintent = new Intent(this, some.class);
startActivity(myintent);
}
当我运行应用程序并按下布局时,它会崩溃,并且我会收到非法状态异常。
我的logcat:
java.lang.IllegalStateException: Could not find a method layout(View) in the activity class android.view.ContextThemeWrapper for onClick handler on view class android.widget.RelativeLayout with id 'mylayout'
Caused by: java.lang.NoSuchMethodException: layout [class android.view.View]
我做错了什么?

执行xml中的更改,如下面的代码:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#0D47A1"
android:id="@+id/mylayout">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:text="sometext"/>
</RelativeLayout>
在你的活动中
RelativeLayout relativeLayout;
public class YourActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.NameOfLayout);
relativeLayout = (RelativeLayout)findViewById(R.id.mylayout);
relativeLayout.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Intent myintent = new Intent(getApplicationContext(), some.class);
startActivity(myintent);
}
});
}

删除“查看视图”并更改方法名称“布局”。因为它提到默认值,所以提到Xml布局..
