java - ViewRootImpl : ViewPostImeInputStage processPointer 0 on OnItemClick of Listview in android

Question

我有一个像这样的 cart_layout:

<?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <ListView
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="9"
        android:id="@+id/cart_listview"
        android:layout_gravity="center_horizontal"
        android:background="@color/whiteBg"/>

    <LinearLayout
        android:orientation="horizontal"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:layout_gravity="bottom"
        android:padding="5dp"
        android:gravity="bottom"
        android:background="@color/whiteBg">
        <!-- this layout contains a button and a textview which I don't think is the problem -->
    </LinearLayout>
</LinearLayout>

以及 Cart.java 中的 java 代码:

protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.cart_layout);
    getSupportActionBar().setDisplayShowTitleEnabled(false);
    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    dbhandler = new DatabaseHandler(this);
    product_all = dbhandler.getProduct();
    total = (TextView)findViewById(R.id.cart_total_textview);

    listview = (ListView)findViewById(R.id.cart_listview);
    
    cart_adapter = new Custom_Cart_Adapter(this,product_all);
    listview.setAdapter(cart_adapter);
    
    listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            Log.v("ITEM CLICK","CLICKED ITEM POSITION: "+position);
            Intent intent = new Intent(Cart.this, Item_edit_details.class);
            intent.putExtra("the_product", product_all.get(position));
            startActivity(intent);
        }
    });
}

我只想制作一个 OnItemClick 事件，但每次点击该项目时，即使 listview.setOnItemClickListener 存在与否，Logcat 也会显示

ViewRootImpl: ViewPostImeInputStage processPointer 0

ViewRootImpl: ViewPostImeInputStage processPointer 1

什么都没有发生。

我也看到这样一个奇怪的日志，有时说“真”有时说“假”:

ActivityThread: updateVisibility : ActivityRecord{3308191 token=android.os.BinderProxy@c7ed098 {com.iwant.namhhgames.newiwant/com.iwant.namhhgames.newiwant.Listing_items}} show : false

我不知道它是否与问题有关，我不知道问题何时发生，可能是我搞砸了。

并且 Logcat 仅针对真实设备显示。使用 AVD，什么都不会显示。

感谢您宝贵的时间。

这个运行没有问题，所以也许你的适配器

   @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.testlist);

        ListView listview = (ListView)findViewById(R.id.listest);

        ArrayList<String> cart_adapter = new ArrayList<String>();

        cart_adapter.add("Me");
        cart_adapter.add("Him");
        cart_adapter.add("You");

        listview.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,cart_adapter));

        listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                Log.e("ITEM CLICK","CLICKED ITEM POSITION: "+position);
            }
        });

    }
