这两天做了一个项目,发现标签不能更改任意一个标签的字体的颜色,需求如同置前标签,然后就对tagcloudeview稍做修改做了这么一个demo。不为别的,只为以后自己用的时候方便拷贝。
先看效果图:

在源码里面加了两个方法
代码语言:javascript
复制
/**修改某些位置定点颜色**/ public void setTagsByPosition(HashMap<Integer, Boolean positions, List<String tagList){ this.tags = tagList; this.removeAllViews(); if (tags != null && tags.size() 0) { for (int i = 0; i < tags.size(); i++) { TextView tagView = (TextView) mInflater.inflate(mTagResId, null); if (mTagResId == DEFAULT_TAG_RESID) { tagView.setBackgroundResource(mBackground); tagView.setTextSize(TypedValue.COMPLEX_UNIT_SP, mTagSize); if (positions.get(i)){ tagView.setTextColor(mSeclectTagColor); }else{ tagView.setTextColor(mTagColor); } } LayoutParams layoutParams = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); tagView.setLayoutParams(layoutParams); tagView.setText(tags.get(i)); tagView.setTag(TYPE_TEXT_NORMAL); final int finalI = i; tagView.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { if (onTagClickListener != null) { onTagClickListener.onTagClick(finalI); } } }); addView(tagView); } } postInvalidate(); } /**最前面的修改颜色**/ public void setTagsByLength(int length,List<String tagList){ this.tags = tagList; this.removeAllViews(); if (tags != null && tags.size() 0) {
for (int i = 0; i < tags.size(); i++) { TextView tagView = (TextView) mInflater.inflate(mTagResId, null); if (mTagResId == DEFAULT_TAG_RESID) { tagView.setBackgroundResource(mBackground); tagView.setTextSize(TypedValue.COMPLEX_UNIT_SP, mTagSize); if (i = length){ tagView.setTextColor(mTagColor); }else{ tagView.setTextColor(mSeclectTagColor); } } LayoutParams layoutParams = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); tagView.setLayoutParams(layoutParams); tagView.setText(tags.get(i)); tagView.setTag(TYPE_TEXT_NORMAL); final int finalI = i; tagView.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { if (onTagClickListener != null) { onTagClickListener.onTagClick(finalI); } } }); addView(tagView); } } postInvalidate();
}
一目了然的方法,所以不多做解释
另外加了一个选中字体颜色的全局常量,和一个int变量
代码语言:javascript
复制
private static final int SELCECT_TEXT_COLOR = R.color.yellow_bg;//选中后的标签颜色
private int mSeclectTagColor;
在styles.xml中给TagCloudView增加了一个选中字体颜色的attr
代码语言:javascript
复制
<attr name="tcvSeclecTextColor" format="reference" /
剩下就是运用的地方
不多说,直接上代码
代码语言:javascript
复制

private TagCloudView positionsView;//定点
