问题描述
我有一个RecyclerViewAdapter，我称它为MyAdapter，并在其中设置了书签:ID，名称，图标，SearchUrl.
I have a RecyclerViewAdapter which I have called MyAdapter and there I set for a Bookmark: ID, Name, Icon, SearchUrl.
我能够显示所有这些内容，但是对于图标，它仅在Drawable中有效.
我不想将位图转换为Drawable，我只想获取保存在DB中的url的图标.
我想从位图中获取收藏夹图标，因为该图标依赖于例如它从哪个SearchUrl给出.
SearchUrl =" https://www.youtube.com "
在图标中，我需要显示youtube的收藏夹.
正如我手动说的那样，这可从drawable起作用，但这取决于用户，我不知道它是写哪种类型的Url.
I am able to show all of them but for the icon it works only from Drawable.
I don't want to convert Bitmap to Drawable I only want take favicon of url which is saved in DB.
I want to take the favicon from the Bitmap because the icon depens from which SearchUrl it is gaven for example.
SearchUrl = "https://www.youtube.com"
In the icon I need to show the favicon of the youtube.
As I said manually this works from drawable but this is depended from the user which I do not know what kind of Url it is written.
下面您可以找到代码.
@Override
public void onBindViewHolder(@NonNull RecyclerView.ViewHolder holder, final int position) {
final int itemType = getItemViewType(position);
if (itemType == ITEM_TYPE_ONE) {
final ViewHolder viewHolder = (ViewHolder) holder;
viewHolder.tvName.setText(arrayList.get(position).getName());
Bitmap bitmap = BitmapFactory.decodeStream((InputStream)new URL(viewHolder.tvSearchUrl.setText(arrayList.get(position).getSearchUrl())).getContent()); //Here is the error of the new URL
viewHolder.tvIcon.setImageBitmap(bitmap);
viewHolder.tvId.setText(arrayList.get(position).getId());
viewHolder.tvSearchUrl.setText(arrayList.get(position).getSearchUrl());
viewHolder.tvNativeUrl.setText(arrayList.get(position).getNativeUrl());
viewHolder.tvIcon.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent;
String Url = viewHolder.tvSearchUrl.getText().toString();
String Name = viewHolder.tvName.getText().toString();
intent = new Intent(context, BookmarkActivity.class);
intent.putExtra("WebSearchUrl", Url);
intent.putExtra("WebSearchName", Name);
v.getContext().startActivity(intent);
}
});
viewHolder.tvIcon.setOnLongClickListener(new View.OnLongClickListener() {
@Override
public boolean onLongClick(View v) {
Intent intent = new Intent(context, ActivityChangeBookmark.class);
String Url = viewHolder.tvSearchUrl.getText().toString();
String Name = viewHolder.tvName.getText().toString();
Integer Id = viewHolder.tvId.getId();
Bundle extras = new Bundle();
viewHolder.tvIcon.buildDrawingCache();
Bitmap image = viewHolder.tvIcon.getDrawingCache();
intent.putExtra("Url", Url);
intent.putExtra("Name", Name);
intent.putExtra("ID", Id);
extras.putParcelable("Image", image);
intent.putExtras(extras);
v.getContext().startActivity(intent);
return false;
}
});
} else if (itemType == ITEM_TYPE_TWO) {
ButtonViewHolder buttonViewHolder = (ButtonViewHolder) holder;
buttonViewHolder.imgButton.setImageResource(arrayList.get(position).getIcon());
}
}
如果我更改viewHolder.tvIcon.setImageResource(arrayList.get(position).getIcon());
比这要来自可绘制对象，并且仅适用于可绘制对象中的图标.
If I change viewHolder.tvIcon.setImageResource(arrayList.get(position).getIcon());
than this takes from the drawable and workd only for the icons which are in drawable.

示例代码如何使用
布局
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/parentView" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_margin="10dp" android:orientation="vertical"> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal"> <ImageView android:id="@+id/stackIMG" android:layout_width="32dp" android:layout_height="32dp" android:layout_margin="10dp" /> <ImageView android:id="@+id/fbIMG" android:layout_width="32dp" android:layout_height="32dp" android:layout_margin="10dp" /> <ImageView android:id="@+id/twitterIMG" android:layout_width="32dp" android:layout_height="32dp" android:layout_margin="10dp" /> </LinearLayout> </LinearLayout>活动代码
import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.widget.ImageView; import com.bumptech.glide.Glide; import com.bumptech.glide.request.RequestOptions; public class MainActivity extends AppCompatActivity { String stackOverFlowURL, FacebookURL, TwitterURL; String BASE_URL = "https://besticon-demo.herokuapp.com/icon?url="; ImageView stackIMG,fbIMG,twitterIMG; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); stackIMG = findViewById(R.id.stackIMG); fbIMG = findViewById(R.id.fbIMG); twitterIMG = findViewById(R.id.twitterIMG); stackOverFlowURL = BASE_URL + "https://stackoverflow.com/" + "&size=32;"; FacebookURL = BASE_URL + "https://www.facebook.com/" + "&size=32;"; TwitterURL = BASE_URL + "https://twitter.com" + "&size=32;"; RequestOptions requestOptions = new RequestOptions(); requestOptions.error(R.drawable.ic_fav); Glide.with(MainActivity.this) .load(stackOverFlowURL) .apply(requestOptions) .into(stackIMG); Glide.with(MainActivity.this) .load(FacebookURL) .apply(requestOptions) .into(fbIMG); Glide.with(MainActivity.this) .load(TwitterURL) .apply(requestOptions) .into(twitterIMG); } }输出
更新
在代码中进行以下更改
@Override public void onBindViewHolder(@NonNull RecyclerView.ViewHolder holder, final int position) { String BASE_URL = "https://besticon-demo.herokuapp.com/icon?url="; final int itemType = getItemViewType(position); if (itemType == ITEM_TYPE_ONE) { final ViewHolder viewHolder = (ViewHolder) holder; viewHolder.tvName.setText(arrayList.get(position).getName()); Glide.with(context) .load(BASE_URL+arrayList.get(position).getSearchUrl()+"&size=32;") .apply(requestOptions) .into(viewHolder.tvIcon); viewHolder.tvId.setText(arrayList.get(position).getId()); viewHolder.tvSearchUrl.setText(arrayList.get(position).getSearchUrl()); viewHolder.tvNativeUrl.setText(arrayList.get(position).getNativeUrl()); viewHolder.tvIcon.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { Intent intent; String Url = viewHolder.tvSearchUrl.getText().toString(); String Name = viewHolder.tvName.getText().toString(); intent = new Intent(context, BookmarkActivity.class); intent.putExtra("WebSearchUrl", Url); intent.putExtra("WebSearchName", Name); v.getContext().startActivity(intent); } }); viewHolder.tvIcon.setOnLongClickListener(new View.OnLongClickListener() { @Override public boolean onLongClick(View v) { Intent intent = new Intent(context, ActivityChangeBookmark.class); String Url = viewHolder.tvSearchUrl.getText().toString(); String Name = viewHolder.tvName.getText().toString(); Integer Id = viewHolder.tvId.getId(); Bundle extras = new Bundle(); viewHolder.tvIcon.buildDrawingCache(); Bitmap image = viewHolder.tvIcon.getDrawingCache(); intent.putExtra("Url", Url); intent.putExtra("Name", Name); intent.putExtra("ID", Id); extras.putParcelable("Image", image); intent.putExtras(extras); v.getContext().startActivity(intent); return false; } }); } else if (itemType == ITEM_TYPE_TWO) { ButtonViewHolder buttonViewHolder = (ButtonViewHolder) holder; buttonViewHolder.imgButton.setImageResource(arrayList.get(position).getIcon()); } }这篇关于从Web获取Favicon，并将其保存到Pojo类中的声明的Icon中的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
