次のコードでレイアウト展開アニメーションを実行しました。テキストビューをクリックしてアニメーションを呼び出すと問題なく動作しますが、レイアウトをクリックしてアニメーションを実行しようとすると同じことが起こりません。誰でもこれを解決するのを手伝ってもらえますか?
LinearLayout hello= (LinearLayout)findViewById(R.id.lin_hello);
final RelativeLayout rel=(RelativeLayout)findViewById(R.id.rel_nah_hide);
hello.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
expand=!expand;
Animation a=expand(rel, expand);
rel.setAnimation(a);
a.start();
}
});
public static Animation expand(final View v, final boolean expand) {
try {
Method m = v.getClass().getDeclaredMethod("onMeasure", int.class, int.class);
m.setAccessible(true);
m.invoke(v,
MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED),
MeasureSpec.makeMeasureSpec(((View)v.getParent()).getMeasuredWidth(), MeasureSpec.AT_MOST)
);
} catch (Exception e) {
e.printStackTrace();
}
final int initialHeight = v.getMeasuredHeight();
if (expand) {
v.getLayoutParams().height = 0;
} else {
v.getLayoutParams().height = initialHeight;
}
v.setVisibility(View.VISIBLE);
Animation a = new Animation() {
@Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
int newHeight = 0;
if (expand) {
newHeight = (int) (initialHeight * interpolatedTime);
} else {
newHeight = (int) (initialHeight * (1 - interpolatedTime));
}
v.getLayoutParams().height = newHeight;
v.requestLayout();
if (interpolatedTime == 1 && !expand)
v.setVisibility(View.GONE);
}
@Override
public boolean willChangeBounds() {
return true;
}
};
a.setDuration(SPEED_ANIMATION_TRANSITION);
a.setAnimationListener(new AnimationListener(){
@Override
public void onAnimationEnd(Animation arg0) {
animWorkingFlag=false;
}
@Override
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub
}
@Override
public void onAnimationStart(Animation animation) {
animWorkingFlag=true;
}
});
return a;
}
以下はxmlレイアウトです。
