自 Glide 较早的更新以来，SimpleTarget 已被弃用

Glide.with(getActivity())
        .load(uri)
        .asBitmap()
        .error(R.drawable.no_result)
        .diskCacheStrategy(DiskCacheStrategy.ALL)
        .into(new SimpleTarget<Bitmap>() {
            @Override
            public void onResourceReady(final Bitmap bitmap, GlideAnimation glideAnimation) {
                imageView.setImageBitmap(bitmap);
                imageView.buildDrawingCache();
            }
        });

我想在用户输入字符时自定义edittext,然后edittext将其更改为图像.看起来像图像:

注意:●图像不是符号.

我有一个顶部和底部有圆角的列表视图.看起来像这个图像:

但是当我单击ListView的顶部和底部时,List Item的背景是矩形而不是圆形作为ListView的顶部和底部背景.喜欢这个图片:

如何解决这个问题？

这是我的代码:

1/list_activity.xml

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

<ListView
    android:id="@+id/listView3"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_margin="10dp"
    android:background="@drawable/list_border"
    android:listSelector="@drawable/list_selector"/>
</LinearLayout>

2/list_border.xml

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#fff"/>
<corners android:bottomRightRadius="10dp"
    android:bottomLeftRadius="10dp"
    android:topLeftRadius="10dp"
    android:topRightRadius="10dp"/>
</shape>

3/list_selector.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true"
        android:drawable="@color/colorPrimary" />
</selector>

4/ListActivity.java

ListView listView = (ListView)findViewById(R.id.listView3);

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

for(int i=0;i<20;i++){
    listItems.add(""+i);
}

ArrayAdapter<String> adapter = new ArrayAdapter<>(getApplicationContext(), android.R.layout.simple_selectable_list_item, listItems);
listView.setAdapter(adapter);

我有一个EditText实现TextWatcher，但是Backspace键有问题。按住退格键时，前5个字符被一一清除，但是按住退格键时，转换为图像的后5个字符不能一一清除。

看图片：

1. MainActivity.java

   public class MainActivity extends AppCompatActivity {
   Spannable.Factory spannableFactory;
   
   protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.activity_main);
   spannableFactory = Spannable.Factory
           .getInstance();
   
   final EditText editText = (EditText) findViewById(R.id.editText);
   editText.addTextChangedListener(new TextWatcher() {
       @Override
       public void beforeTextChanged(CharSequence s, int start, int count, int after) { }
   
       @Override
       public void onTextChanged(CharSequence s, int start, int before, int count) {
           editText.removeTextChangedListener(this);
           if (s.length() >= 5) {
               editText.setText(getTextToIcon(getApplicationContext(), s));
           }
           if(count!=0){                               // != key delete
               if (s.length() - 1 > start) {
                   editText.setSelection(start + 1); …
