如何在TextView中实现hashtag?我想要做的是在 textview 中实现可链接的主题标签。然后用户可以单击它(主题标签)并切换到另一个 fragment 。这是我的布局和 fragment 。
布局
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/activity_main_fragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".MainFragment" >
<TextView
android:id="@+id/txtHashtag"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Iena I #love you !!!"/>
</RelativeLayout>
fragment
package com.xxxx;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import com.xxxxx.R;
public class MainFragment extends Fragment{
private TextView txtHashtag;
public MainFragment() {
// TODO Auto-generated constructor stub
}
@Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
View v = LayoutInflater.from(getActivity()).inflate(R.layout.activity_main_fragment,
null);
txtHashtag = (TextView) v.findViewById(R.id.txtHashtag);
return v;
}
@Override
public void onDestroy() {
super.onDestroy();
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
}
}
最佳答案
您可以使用这个简单的库 HashTagHelper
它的用法非常简单:
mHashTagText = (TextView) findViewById(R.id.text);
mTextHashTagHelper = HashTagHelper.Creator.create(getResources().getColor(R.color.colorPrimary),
new HashTagHelper.OnHashTagClickListener() {
@Override
public void onHashTagClicked(String hashTag) {
}
});
// pass a TextView or any descendant of it (incliding EditText) here.
// Hash tags that are in the text will be hightlighed with a color passed to HasTagHelper
mTextHashTagHelper.handle(mHashTagText);
