我正在我的应用程序中使用ShowCaseView库。我想将"确定"按钮向左移动。我使用了以下代码(在库中相同):
// The following code will reposition the OK button to the left.
RelativeLayout.LayoutParams lps = new RelativeLayout.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
lps.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
lps.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
int margin = ((Number) (getResources().getDisplayMetrics().density * 12))
.intValue();
lps.setMargins(margin, margin, margin, margin);
View showcasedView = findViewById(R.id.ib_next);
ViewTarget target = new ViewTarget(showcasedView);
ShowcaseView.ConfigOptions co = new ShowcaseView.ConfigOptions();
co.buttonLayoutParams = lps;
co.fadeInDuration = 1000;
co.fadeOutDuration = 1000;
ShowcaseView sv = ShowcaseView.insertShowcaseView(target, this,
R.string.showcase_title, R.string.showcase_details, co);
但是它不起作用?谁能说出问题出在哪里?
我知道
这个问题已经很老了,但如果有人需要有效的解决方案:
RelativeLayout.LayoutParams lps = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
// This aligns button to the bottom left side of screen
lps.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
lps.addRule(RelativeLayout.ALIGN_PARENT_LEFT);
// Set margins to the button, we add 16dp margins here
int margin = ((Number) (getResources().getDisplayMetrics().density * 16)).intValue();
lps.setMargins(margin, margin, margin, margin);
ViewTarget target = new ViewTarget(R.id.buttonBlocked, this);
sv = new ShowcaseView.Builder(this)
.withMaterialShowcase()
.setTarget(target)
.setContentTitle(R.string.showcase_main_title)
.setContentText(R.string.showcase_main_message)
.build();
// Set declared button position to ShowcaseView
sv.setButtonPosition(lps);
这对我有用,希望它对某人有所帮助。
