我有一个带有垂直搜索栏的 LinearLayout
。对于垂直搜索栏,我使用的是自定义类。使用 android:layout_weight="1"
搜索栏拇指对齐不正确。
verticalseekbar.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<com.example.verticalseekbardemo.VerticalSeekBar
android:id="@+id/seekBar1"
android:layout_width="0dp"
android:layout_height="200dp"
android:layout_weight="1"
android:progress="50" />
<com.example.verticalseekbardemo.VerticalSeekBar
android:id="@+id/seekBar2"
android:layout_width="0dp"
android:layout_height="200dp"
android:layout_weight="1"
android:progress="30" />
<com.example.verticalseekbardemo.VerticalSeekBar
android:id="@+id/seekBar3"
android:layout_width="0dp"
android:layout_height="200dp"
android:layout_weight="1"
android:progress="10" />
<com.example.verticalseekbardemo.VerticalSeekBar
android:id="@+id/seekBar4"
android:layout_width="0dp"
android:layout_height="200dp"
android:layout_weight="1" />
<com.example.verticalseekbardemo.VerticalSeekBar
android:id="@+id/seekBar5"
android:layout_width="0dp"
android:layout_height="200dp"
android:layout_weight="1"
android:progress="80" />
</LinearLayout>
VerticalSeekBar.java
public class VerticalSeekBar extends SeekBar{
public VerticalSeekBar(Context context) {
super(context);
}
public VerticalSeekBar(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public VerticalSeekBar(Context context, AttributeSet attrs) {
super(context, attrs);
}
protected void onSizeChanged(int w, int h, int oldw, int oldh) {
super.onSizeChanged(h, w, oldh, oldw);
}
@Override
public synchronized void setProgress(int progress) // it is necessary for
// calling setProgress
// on click of a button
{
super.setProgress(progress);
onSizeChanged(getWidth(), getHeight(), 0, 0);
}
@Override
protected synchronized void onMeasure(int widthMeasureSpec,
int heightMeasureSpec) {
super.onMeasure(heightMeasureSpec, widthMeasureSpec);
setMeasuredDimension(getMeasuredHeight(), getMeasuredWidth());
}
protected void onDraw(Canvas c) {
c.rotate(-90);
c.translate(-getHeight(), 0);
super.onDraw(c);
}
@Override
public boolean onTouchEvent(MotionEvent event) {
if (!isEnabled()) {
return false;
}
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
case MotionEvent.ACTION_MOVE:
case MotionEvent.ACTION_UP:
setProgress(getMax()
- (int) (getMax() * event.getY() / getHeight()));
onSizeChanged(getWidth(), getHeight(), 0, 0);
break;
case MotionEvent.ACTION_CANCEL:
break;
}
return true;
}
}
有没有人遇到过这种问题。
谢谢。
最佳答案
我遇到了同样的问题。解决它的唯一方法是将每个搜索栏放入一个 FrameLayout 中,如下所示:
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1">
<com.example.verticalseekbardemo.VerticalSeekBar
android:id="@+id/seekBar1"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:progress="50" />
</FrameLayout>
希望对你有帮助。
