TagsEditText for hashTags
Bài đăng này đã không được cập nhật trong 7 năm
Ever wanted to add tag features to your edittext? Tags such as #tags or @mentions and handle each of the tags as a seperate object. If so then search no more as TagEditText library will do just that. To demostrate this lets start by creating a project and name it whatever we please. Mine is called TagEditTextApp.
Step 1 Add it in your root build.gradle at the end of repositories:
allprojects {
repositories {
maven { url "https://jitpack.io" }
}
}
Step 2 Add the dependency
dependencies {
compile 'com.github.mabbas007:TagsEditText:1.0.5'
}
Now that we have imported the library we can use it instead of the regular Edittext for our mentions/HashTags.
Create a xml in res value folder for template suggestions.

Next create a drawable file to be used as the tags background. square_default.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<padding
android:bottom="1dp"
android:left="1dp"
android:right="1dp"
android:top="1dp" />
<solid android:color="@color/bg_tag_default" />
</shape>
Go into your activity_main.xml and edit the layout as such: activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:TagsEditText="http://schemas.android.com/apk/res-auto"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="10dp"
android:background="@android:color/black"
tools:context="com.example.framgiababatundefatoyesunday.tagedittextapp.MainActivity"
>
<mabbas007.tagsedittext.TagsEditText
android:id="@+id/tagsEditText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
TagsEditText:tagsBackground="@drawable/square_default"
TagsEditText:tagsCloseImageRight="@drawable/tag_close"
android:textColor="@android:color/white"
android:textSize="16sp"
app:tagsTextSize="16sp"
/>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/done"
android:layout_alignParentBottom="true"
/>
</RelativeLayout>
The (mabbas007.tagsedittext.TagsEditText) is the custom edittext and it support custom xml and java properties that can make tagging much more easier. Below are some of the properties.
- TagsEditText:tagsBackground: Will set the background of the tags
- TagsEditText:tagsCloseImageRight: To set a drawable image (on the right usually to delete a tag)
- app:tagsTextSize sets the tag text size
MainActivity
package com.example.framgiababatundefatoyesunday.tagedittextapp;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.Toast;
import java.util.ArrayList;
import java.util.Collection;
import mabbas007.tagsedittext.TagsEditText;
public class MainActivity extends AppCompatActivity implements TagsEditText.TagsEditListener {
private ArrayAdapter arrayAdapter;
private TagsEditText mTagsEditText;
private Button mBtnDone;
private Collection<String> mCollection = new ArrayList<>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTagsEditText = (TagsEditText) findViewById(R.id.tagsEditText);
mBtnDone = (Button) findViewById(R.id.btnDone);
mBtnDone.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (mCollection == null || mCollection.isEmpty()) {
Toast.makeText(MainActivity.this, "Empty", Toast.LENGTH_SHORT).show();
return;
}
for (String country : mCollection)
Toast.makeText(MainActivity.this, country, Toast.LENGTH_SHORT).show();
}
});
mTagsEditText.setHint("Enter names of country");
mTagsEditText.setTagsListener(this);
//To Disable space click (Adds text to tags)
// mTagsEditText.setTagsWithSpacesEnabled(true);
arrayAdapter = new ArrayAdapter<>(this, android.R.layout.simple_dropdown_item_1line,
getResources().getStringArray(R.array.country));
mTagsEditText.setAdapter(arrayAdapter);
mTagsEditText.setThreshold(1);
}
@Override
public void onTagsChanged(Collection<String> collection) {
mCollection = collection;
}
@Override
public void onEditingFinished() {
}
}
The advantage of using this library is that all tags are treated as a single individual objects and not strings. It can easily be deleted and modified to keep user from inputing unnecessary texts. More info can be found on the official git here
