最近在修改之前的代码发现了有个页面布局如下
这样的话就会导致字体增多就很难看
原始xml布局如下 只截取有关部分
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="@dimen/ten"
android:gravity="center_vertical"
android:orientation="horizontal">
<TextView
android:id="@+id/upload_from"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="4sp"
android:text=""
android:textColor="@color/blue"
android:textSize="12sp"
android:textStyle="bold" />
<TextView
android:id="@+id/reply"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="4dp"
android:text=""
android:textColor="@color/defcolor2"
android:textSize="12sp"
android:visibility="gone"
/>
<TextView
android:id="@+id/upload_to"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="4sp"
android:text=""
android:textColor="@color/blue"
android:textSize="12sp"
android:textStyle="bold"
android:visibility="gone"
/>
<TextView
android:id="@+id/upload_board"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:layout_marginRight="10dp"
android:gravity="center|left"
android:text=""
android:textColor="@color/defcolor0"
android:textSize="12sp" />
</LinearLayout>
相关逻辑判断
private void getbusinesslist() {
adapter = new LCommonAdapter<GetUploadingMessageBean.DataBean>(mContext, R.layout.item_message_board_info) {
@Override
protected void convert(LViewHolder viewHolder, GetUploadingMessageBean.DataBean item, int position) {
viewHolder.setText(R.id.upload_board, item.getContent());
viewHolder.setText(R.id.upload_from, item.getUserName() + ":");
viewHolder.setVisible(R.id.reply, false);
viewHolder.setVisible(R.id.upload_to, false);
if (!TextUtils.isEmpty(item.getReplyName())) {
viewHolder.setVisible(R.id.reply, true);
viewHolder.setText(R.id.reply, "回复");
viewHolder.setText(R.id.upload_to, item.getReplyName()+":");
viewHolder.setVisible(R.id.upload_to, true);
}
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:SS");
Date d1 = new Date(item.getCreateTime());
String t1 = format.format(d1);
viewHolder.setText(R.id.upload_time, t1);
viewHolder.setOnClickListener(R.id.reply_msg, new View.OnClickListener() {
@Override
public void onClick(View v) {
uploadto = item.getUserName();
et_message.setHint("回复:" + uploadto);
et_message.setFocusable(true);
et_message.setFocusableInTouchMode(true);
et_message.requestFocus();
//弹出软键盘
InputMethodManager inputManager = (InputMethodManager) et_message.getContext()
.getSystemService(Context.INPUT_METHOD_SERVICE);
inputManager.showSoftInput(et_message, 0);
}
});
}
};
adapter.clear();
adapter.notifyDataSetChanged();
live_message.setAdapter(adapter);
live_message.setFocusable(false);
}
代码很繁琐而且布局也不对
解决方案：
Xml文件修改为
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="@dimen/ten"
android:gravity="center_vertical"
android:orientation="horizontal">
<TextView
android:id="@+id/content"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:layout_marginRight="10dp"
android:gravity="center|left"
android:text=""
android:textColor="@color/defcolor0"
android:textSize="12sp" />
</LinearLayout>
这里只使用一个TextView
逻辑判断
private void getbusinesslist() {
adapter = new LCommonAdapter<GetUploadingMessageBean.DataBean>(mContext, R.layout.item_message_board_info_test) {
@Override
protected void convert(LViewHolder viewHolder, GetUploadingMessageBean.DataBean item, int position) {
String content=item.getContent();
String from=item.getUserName();
String to=item.getReplyName();
String replymsg=from+" 回复 :"+to+" "+content;
int countfrom=from.length();
int countto=from.length();
String noreply=from+" : "+content;
if (!TextUtils.isEmpty(to)){
SpannableString spannableString=new SpannableString(replymsg);
// ForegroundColorSpan span=new ForegroundColorSpan(mContext.getResources().getColor(R.color.blue));
// spannableString.setSpan(span,0, countfrom, Spannable.SPAN_EXCLUSIVE_INCLUSIVE);
// spannableString.setSpan(span,countfrom+5,countfrom+5+countto,Spannable.SPAN_EXCLUSIVE_INCLUSIVE);
spannableString.setSpan(CharacterStyle.wrap(new ForegroundColorSpan(mContext.getResources().getColor(R.color.blue))),0, countfrom, Spannable.SPAN_EXCLUSIVE_INCLUSIVE);
spannableString.setSpan(CharacterStyle.wrap(new ForegroundColorSpan(mContext.getResources().getColor(R.color.blue))),countfrom+5,countfrom+5+countto,Spannable.SPAN_EXCLUSIVE_INCLUSIVE);
viewHolder.setText(R.id.content,spannableString);
}else {
SpannableString spannableString=new SpannableString(noreply);
ForegroundColorSpan span=new ForegroundColorSpan(mContext.getResources().getColor(R.color.blue));
spannableString.setSpan(span,0, countfrom, Spannable.SPAN_EXCLUSIVE_INCLUSIVE);
viewHolder.setText(R.id.content,spannableString);
}
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:SS");
Date d1 = new Date(item.getCreateTime());
String t1 = format.format(d1);
viewHolder.setText(R.id.upload_time, t1);
viewHolder.setOnClickListener(R.id.reply_msg, new View.OnClickListener() {
@Override
public void onClick(View v) {
uploadto = item.getUserName();
et_message.setHint("回复:" + uploadto);
et_message.setFocusable(true);
et_message.setFocusableInTouchMode(true);
et_message.requestFocus();
//弹出软键盘
InputMethodManager inputManager = (InputMethodManager) et_message.getContext()
.getSystemService(Context.INPUT_METHOD_SERVICE);
inputManager.showSoftInput(et_message, 0);
}
});
}
};
adapter.clear();
adapter.notifyDataSetChanged();
live_message.setAdapter(adapter);
live_message.setFocusable(false);
}
使用SpannableStringBuilder 即可操作同一个TextView中的值实现不同样式和颜色，这里使用方法就不举例了
需要注意的是也是踩坑的是
在同一个spannablestring中同时使用两次
.span方法时会有一个方法不起效，即使你确定了两次方法的起始和终止位置不同但也没用
如上文
spannableString.setSpan(CharacterStyle.wrap(new ForegroundColorSpan(mContext.getResources().getColor(R.color.blue))),0, countfrom, Spannable.SPAN_EXCLUSIVE_INCLUSIVE);
我使用了
CharacterStyle.wrap（）的方法进行带入

最终实现效果如下所示：可以看到就很好了不会出现布局错乱的问题了
