你能帮助我吗？当我按下按钮时，它保持按下状态，但什么也不做。
对不起，我的英语不好！:)
谢谢！
fasmenupincipal.xml 文件：
<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
我想从膨胀布局开始一个新的活动。我制作了一个滚动视图，然后将视图添加到滚动视图中，从而使布局膨胀。这是de java代码：
public class ProvaPedidoScroll extends Activity {
Context mContext;
HorizontalScrollView mScrollView;
LinearLayout mLinearLayout;
LinearLayout.LayoutParams mLinearLayoutParams;
Display mDisplay;
// scroll behaviour
private int mScrollStartPosition;
private static final float SCROLL_MARGIN = 0.2f;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mContext = this;
// load layout from xml and get references to sub-views
setContentView(R.layout.scrollview);
mScrollView = (HorizontalScrollView) findViewById(R.id.scrollview);
mLinearLayout = (LinearLayout) findViewById(R.id.scrollviewlinearlayout);
// get a display reference (used to find screen size)
mDisplay = ((WindowManager) mContext.getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay();
// get the layout parameters to apply to the sub-views
mLinearLayoutParams = new LayoutParams(mDisplay.getWidth(), mDisplay.getHeight());
// add some views to the ScrollView
addViewsToScrollView();
}
/**
* Inflates and adds some views to the ScrollView
*/
private void addViewsToScrollView() {
LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
View menuprincipal = inflater.inflate(R.layout.fasmenuprincipal, null);
menuprincipal.setLayoutParams(mLinearLayoutParams);
mLinearLayout.addView(menuprincipal);
Button ClientesMenu = (Button) menuprincipal.findViewById(R.id.button1);
ClientesMenu.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
int iOpcio = 1;
Intent VeureClients = new Intent(ProvaPedidoScroll.this, buscar_client.class);
VeureClients.putExtra("Opcio", iOpcio);
startActivity(VeureClients);
}
});
View view2 = inflater.inflate(R.layout.fasmenugestion, null);
view2.setLayoutParams(mLinearLayoutParams);
mLinearLayout.addView(view2);
}
@Override
public boolean dispatchTouchEvent(MotionEvent ev) {
int viewWidth = mDisplay.getWidth(); // width of each view
int triggerWidth = (int) (SCROLL_MARGIN * viewWidth); // amount user has to scroll to move to next view
int pos = mScrollView.getScrollX();
int diff = pos % viewWidth; // offset of current scroll from leftmost view's snap position
int posLeftView = pos - diff; // absolute snap position of the leftmost view on screen
switch (ev.getAction()) {
case MotionEvent.ACTION_DOWN:
// Record the starting scroll position. This is used to decide the scroll direction.
mScrollStartPosition = pos;
break;
case MotionEvent.ACTION_UP:
if (pos > mScrollStartPosition) {
// Scrolling right
if (diff > triggerWidth) mScrollView.smoothScrollTo(posLeftView + viewWidth, 0);
else mScrollView.smoothScrollTo(posLeftView, 0);
} else {
// Scrolling left
if (diff > (viewWidth - triggerWidth)) mScrollView.smoothScrollTo(posLeftView + viewWidth, 0);
else mScrollView.smoothScrollTo(posLeftView, 0);
}
// replacing our scrollTo command with it's own
return true;
}
return super.dispatchTouchEvent(ev);
}
}
