实现adapter

}
package com.example.moni3;

解析json
public class Person {
public List result;
public String message;
public int status;

public List getResult() { return result; }public void setResult(List result) { this.result = result; }public String getMessage() { return message; }public void setMessage(String message) { this.message = message; }public int getStatus() { return status; }public void setStatus(int status) { this.status = status; }public static class ResultDate{public int id; public String imageUrl; public String name; public int rank; public String summary; public int getId() { return id; }public void setId(int id) { this.id = id; }public String getImageUrl() { return imageUrl; }public void setImageUrl(String imageUrl) { this.imageUrl = imageUrl; }public String getName() { return name; }public void setName(String name) { this.name = name; }public int getRank() { return rank; }public void setRank(int rank) { this.rank = rank; }public String getSummary() { return summary; }public void setSummary(String summary) { this.summary = summary; } }

}
package com.example.moni3;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.TextView;
public class SendActivity extends AppCompatActivity {

private TextView name; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_send); name = findViewById(R.id.name); Intentintent = getIntent(); String name1 = intent.getStringExtra("name"); this.name.setText(name1); }

}
进行BaseActivity的抽取
package com.example.moni3;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
public abstract class BaseActivity extends AppCompatActivity {

@Override protected void onCreate(@Nullable Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(getLayoutId()); init(); initViewBar(); }protected abstract int getLayoutId(); protected abstract void init(); protected abstract void initViewBar();

}
携带数据进行跳转到另一个activity(创建新的activity)
package com.example.moni3;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.ImageView;
import android.widget.TextView;
import com.nostra13.universalimageloader.core.ImageLoader;
public class SendActivity extends BaseActivity {

private TextView name; private ImageView image; @Override protected int getLayoutId() { return R.layout.activity_send; }@Override protected void init() {name = findViewById(R.id.name); image = findViewById(R.id.image); Intentintent = getIntent(); String name1 = intent.getStringExtra("name"); String namen = intent.getStringExtra("name1"); ImageLoader.getInstance().displayImage(name1,image,ImageConfs.getMan()); this.name.setText(namen); }@Override protected void initViewBar() {}

【侧拉框+Xlist下拉加载数据+跳转activity】}
