单击按钮后,鼠标滚动将被激活并向上滚动,按钮值应该增加,当向下滚动时值减少。但按钮外部代码工作,然后按钮内部代码不工作。我的示例代码在这里。
public class MainActivity extends Activity {
Button button;
int x,f;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
button=(Button)findViewById(R.id.button1);
button.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(View arg0, MotionEvent arg1) {
// TODO Auto-generated method stub
// i need implement code here ,how can i do?
return false;
}
});
}
@SuppressLint("NewApi") @Override
public boolean onGenericMotionEvent(MotionEvent event) {
//if (0 != (event.getSource() & InputDevice.SOURCE_CLASS_POINTER)) {
switch (event.getAction()) {
case MotionEvent.ACTION_SCROLL:
if (event.getAxisValue(MotionEvent.AXIS_VSCROLL) < 0.0f)
//selectNext();
{
x=Integer.parseInt(button.getText().toString());
f=x+5;
button.setText(""+f);
}
else
{
x=Integer.parseInt(button.getText().toString());
f=x-5;
button.setText(""+f);
return true;
}
}
return super.onGenericMotionEvent(event);
} }
我需要触摸听众内部的这些功能我不知道该怎么办,请帮助我!
