Get Chip Text on click chip

问题

我是Android的新手,正在尝试使用芯片(Chips)功能。我在XML中有一个类似这样的芯片组(ChipGroup):

<com.google.android.material.chip.ChipGroup
    android:padding="10dp"
    android:id="@+id/tags"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:chipSpacing="10dp">
</com.google.android.material.chip.ChipGroup>

我正在动态地向其中添加芯片,像这样:

Chip chip = new Chip(getLayoutInflater().getContext());
for (String genre : tags_text) {
    chip.setText(genre);
    tags.addView(chip);
}

添加芯片的功能正常。现在我想要获取点击芯片的文本内容。我尝试像这样获取:

chip.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
        int chipsCount = tags.getChildCount();
        String TagText = "";
        int i = 0;
        while (i < chipsCount) {
            Chip chip = (Chip) tags.getChildAt(i);
            if (chip.isChecked()) {
                TagText = chip.getText().toString();
            }
            i++;
        }
        Log.e("CHIPS", TagText + "-OK");
    }
});
但是我总是得到空白的文本。如果有人可以帮助我解决这个问题,请告诉我。谢谢!

I am new to android and trying to play with chips. I have chip group like this in xml

&lt;com.google.android.material.chip.ChipGroup
                                android:padding=&quot;10dp&quot;
                                android:id=&quot;@+id/tags&quot;
                                android:layout_width=&quot;match_parent&quot;
                                android:layout_height=&quot;wrap_content&quot;
                                app:chipSpacing=&quot;10dp&quot;&gt;

                            &lt;/com.google.android.material.chip.ChipGroup&gt;

I am dynamically adding chip like this in it.

Chip chip = new Chip(getLayoutInflater().getContext());
            for(String genre : tags_text) {
               chip.setText(genre);
               tags.addView(chip);
           }

Adding chip is working fine. Now I want get chip text of clicked chip. I am trying to get it like this

chip.setOnClickListener(new View.OnClickListener() {

                                        public void onClick(View v) {
                                            int chipsCount = tags.getChildCount();
                                            String TagText =&quot;&quot;;
                                            int i = 0;
                                            while (i &lt; chipsCount) {
                                                Chip chip = (Chip) tags.getChildAt(i);
                                                if (chip.isChecked() ) {
                                                    TagText = chip.getText().toString();
                                                }
                                                i++;
                                            };
                                            Log.e(&quot;CHIPS&quot;, TagText+&quot;-OK&quot;);
                                        }
                                    });

可以使用:

chip.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        String text = ((Chip) view).getText().toString();
        //...
    }
});
英文:

You can use:

    chip.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            String text = ((Chip) view).getText().toString();
            //...
        }
    });
