垂直和水平滚动视图
垂直和水平滚动视图
提问于 2013-12-05 07:48:21
我使用的是一个需要垂直滚动和水平滚动的桌子。我使用了两个滚动视图，如下所示。是否可以同时使用单一的一种？意思是将一个滚动视图启用为水平和垂直的：
LinearLayout contentView = (LinearLayout) findViewById(R.id.contentView);
TableLayout tableLayout = new TableLayout(getApplicationContext());
TableRow tableRow;
TextView textView;
for (int i = 0; i <28; i++) {
tableRow = new TableRow(getApplicationContext());
for (int j = 0; j < 16; j++) {
textView = new TextView(getApplicationContext());
textView.setText("test");
textView.setPadding(20, 20, 20, 20);
tableRow.addView(textView);
}
tableLayout.addView(tableRow);
}
ScrollView scroll = new ScrollView(MainActivity.this);
scroll.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.FILL_PARENT));
scroll.addView(tableLayout);
HorizontalScrollView horizontalScroll = new HorizontalScrollView(MainActivity.this);
horizontalScroll.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.FILL_PARENT));
horizontalScroll.addView(scroll);
contentView.addView(horizontalScroll);回答 1

可以使用可以在xml文件中使用的自定义滚动视图代码。这是垂直滚动视图的一个小示例，在这里，您也可以使用水平视图
import android.content.Context;
import android.util.AttributeSet;
import android.util.Log;
import android.view.MotionEvent;
import android.widget.ScrollView;
public class VerticalScrollview extends ScrollView {
public VerticalScrollview(Context context) {
super(context);
}
public VerticalScrollview(Context context, AttributeSet attrs) {
super(context, attrs);
}
public VerticalScrollview(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
@Override
public boolean onInterceptTouchEvent(MotionEvent ev) {
final int action = ev.getAction();
switch (action) {
case MotionEvent.ACTION_DOWN:
Log.i("VerticalScrollview",
"onInterceptTouchEvent: DOWN super false");
super.onTouchEvent(ev);
break;
case MotionEvent.ACTION_MOVE:
return false; // redirect MotionEvents to ourself
case MotionEvent.ACTION_CANCEL:
Log.i("VerticalScrollview",
"onInterceptTouchEvent: CANCEL super false");
super.onTouchEvent(ev);
break;
case MotionEvent.ACTION_UP:
Log.i("VerticalScrollview", "onInterceptTouchEvent: UP super false");
return false;
default:
Log.i("VerticalScrollview", "onInterceptTouchEvent: " + action);
break;
}
return false;
}
@Override
public boolean onTouchEvent(MotionEvent ev) {
super.onTouchEvent(ev);
Log.i("VerticalScrollview", "onTouchEvent. action: " + ev.getAction());
return true;
}
