使用 VOLLEY 将 onclickListener 放入 RecyclerViewAdapter 时,图像未显示在新 Activity 中
Image is not displaying in new Activity while putting onclickListener in RecyclerViewAdapter using VOLLEY
图像未在新版中显示 activity...我将 OnclickListener 放在 RecyclerViewAdaptor 上...我正在使用 Volley...我想在新版中同时显示图像和文本 activity ..但只显示文字!!..任何人都可以帮助我吗?
我认为问题出在意图部分....但我不明白为什么图像没有显示

这是新的活动文件
DetailsActivity.java
package com.example.volleydemo;
import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;
import com.bumptech.glide.Glide;
public class DetailsActivity extends AppCompatActivity {
ImageView img;
TextView tv1,tv2;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_details);
img = findViewById(R.id.desc_img);
tv1 = findViewById(R.id.desc_header);
tv2 = findViewById(R.id.desc_desc);
img.setImageResource(getIntent().getIntExtra("imagename",0));
//Glide.with(holder.t1.getContext()).load("http://10.0.2.2/volley/images/"+data[position].getImage()).into(holder.img);
tv1.setText(getIntent().getStringExtra("header"));
tv2.setText(getIntent().getStringExtra("desc"));
}
}
这是持有人class..
DisplayUser.java
package com.example.volleydemo;
public class DisplayUser {
//this is helper class
private String rollno,name,desig,image;
public DisplayUser() {
}
public DisplayUser(String rollno, String name, String desig, String image) {
this.rollno = rollno;
this.name = name;
this.desig = desig;
this.image = image;
}
public String getRollno() {
return rollno;
}
public void setRollno(String rollno) {
this.rollno = rollno;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getDesig() {
return desig;
}
public void setDesig(String desig) {
this.desig = desig;
}
public String getImage() {
return image;
}
public void setImage(String image) {
this.image = image;
}
}
在你的 DetailsActivity,
替换:
img.setImageResource(getIntent().getIntExtra("imagename",0));
Glide.with(holder.t1.getContext()).load("http://10.0.2.2/volley/images/"+data[position].getImage()).into(holder.img);
收件人:
Glide.with(getApplicationContext()).load("http://10.0.2.2/volley/images/"+getIntent().getStringExtra("imagename").into(img);
