xml文件中的布局代码

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:zhy="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:orientation="vertical"
    tools:context=".MainActivity">
    <EditText
        android:id="@+id/edit"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <Button
        android:id="@+id/button"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="点击添加"/>
    <com.zhy.view.flowlayout.TagFlowLayout
        android:id="@+id/id_flowlayout"
        zhy:max_select="-1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="20dp"></com.zhy.view.flowlayout.TagFlowLayout>

</LinearLayout>

MainActivity中的相关代码

public class MainActivity extends AppCompatActivity {

    private TextView textView;
    private List<String> list;
    private EditText editText;
    private TagFlowLayout idflowlayout1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        idflowlayout1 = findViewById(R.id.id_flowlayout);
        editText = findViewById(R.id.edit);
        Button button = findViewById(R.id.button);
        list = new ArrayList<>();
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                list.add(""+ editText.getText().toString());
                idflowlayout1.setAdapter(new TagAdapter<String>(list)
                {
                    @Override
                    public View getView(FlowLayout parent, int position, String s)
                    {
                        textView = new TextView(MainActivity.this);
                        //数据之间的距离
                        textView.setPadding(5, 5, 5, 5);
                        //字体大小
                        textView.setTextSize(20);
                        textView.setText(s);
                        return textView;
                    }
                });
            }
        });
        //设置监听
        idflowlayout1.setOnSelectListener(new TagFlowLayout.OnSelectListener() {
            @Override
            public void onSelected(Set<Integer> selectPosSet) {
                //点击
                Toast.makeText(MainActivity.this, ""+textView.getText().toString(), Toast.LENGTH_SHORT).show();
                //跳转
                startActivity(new Intent(MainActivity.this,TwoActivity.class));
            }
        });
