Question

我的应用程序Listview中包含项，并为此项使用扩展BaseAdapter的适配器。滚动到底部时，其他项目的文本与另一个项目中的文本重叠。

这是Listview的布局代码。

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/fragmentRulesLayout"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical">

    <ListView
        android:id="@+id/fragmentRulesFunctions_listView"
        android:layout_width="match_parent"
        android:layout_height="fill_parent"
        android:layout_weight="1">
    </ListView>

</FrameLayout>

这是此列表视图的项目代码

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/ruleFunction_constraintLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:id="@+id/ruleFunction_tvDeviceName"
        app:layout_constraintWidth_percent = "0.6"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginBottom="10dp"
        android:layout_marginLeft="10dp"
        android:layout_marginStart="10dp"
        android:layout_marginTop="10dp"
        android:textSize="20dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />
</android.support.constraint.ConstraintLayout>

初始化适配器

private void initRuleAdapter() {
ruleFunctionAdapter = new RuleFunctionAdapter(deviceWithFunctionalities, 
getActivity());
listView = view.findViewById(R.id.fragmentRulesFunctions_listView);
listView.setAdapter(ruleFunctionAdapter);
}

和自定义适配器：

public View getView(int i, View view, ViewGroup viewGroup) {
    itemView = view;

    final DeviceWithFunctionalities dwf = deviceWithFunctionalities.get(i);

    itemView = (itemView == null) ? inflater.inflate(R.layout.rule_function_item, null): itemView;

    final TextView tvDeviceName = itemView.findViewById(R.id.ruleFunction_tvDeviceName);
    tvDeviceName.setText(dwf.getName());

    constraintLayout = itemView.findViewById(R.id.ruleFunction_constraintLayout);

    if(dwf.getFunctionalities() != null) {
        for (int j = 0; j < dwf.getFunctionalities().size(); j++) {
            final TextView tvFunction = new TextView(itemView.getContext());

            tvFunction.setId(TextView.generateViewId());
            tvFunction.setText(dwf.getFunctionalities().get(j));
            tvFunction.setTextSize(20);
            tvFunction.setTypeface(null, Typeface.BOLD);

            constraintLayout.addView(tvFunction);

            ConstraintSet constraintSet = new ConstraintSet();
            constraintSet.clone(constraintLayout);

            constraintSet.connect(tvFunction.getId(), ConstraintSet.TOP, constraintLayout.getId(), ConstraintSet.TOP, (j) * 100 + 15);
            constraintSet.connect(tvFunction.getId(), ConstraintSet.RIGHT, constraintLayout.getId(), ConstraintSet.RIGHT, 100);

            constraintSet.applyTo(constraintLayout);

            tvFunction.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    SetRuleFunctionsFragment setRuleFunctionsFragment = new SetRuleFunctionsFragment();
                    Bundle bundle = new Bundle();
                    bundle.putString("DeviceName", tvDeviceName.getText().toString());
                    bundle.putString("DeviceFunction", tvFunction.getText().toString());

                    setRuleFunctionsFragment.setArguments(bundle);

                    FragmentManager fragmentManager = ((AppCompatActivity)context).getSupportFragmentManager();
                    fragmentManager.beginTransaction().
                            replace(R.id.content_frame, setRuleFunctionsFragment, setRuleFunctionsFragment.getTag()).
                            addToBackStack(null).commit();
                }
            });
        }
    }

我试图在Listview中使用

android:animateLayoutChanges="false"

但是它根本没有帮助

以下是问题的屏幕截图：text in item "test5"

真的需要帮助。谢谢！
