1,建立当前的界面内容,获取到当前界面的指定需要传的值,我这儿的值获取的是服务器的值,先上代码看看;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.Menu;
import android.widget.LinearLayout;
import android.widget.TextView;
import android.content.Intent;
import android.os.Handler;
import android.os.Message;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import org.json.JSONObject;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;

public class LoginActivity extends AppCompatActivity implements View.OnClickListener {
private LinearLayout back;
private TextView json_one,json_to,json_there,jsonfire,json_sex;
private Button buttom_canle;
private Handler handler;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
handler=new MyHandler();
json_one=(TextView)findViewById(R.id.json_one);
json_to=(TextView)findViewById(R.id.json_to);
json_there=(TextView)findViewById(R.id.json_there);
jsonfire=(TextView)findViewById(R.id.json_fire);
json_sex=(TextView)findViewById(R.id.json_sex);
back=(LinearLayout)findViewById(R.id.back);
back.setOnClickListener(this);//点击跳转界面
}
@Override
public void onClick(View v) {
if(v==back){
String s1 = json_one.getText().toString();//获取到列表的数据值
String s2 = json_to.getText().toString();
String s4 = jsonfire.getText().toString();
String s3 = json_there.getText().toString();
Intent intent = new Intent(LoginActivity.this, NameActivity.class);
intent.putExtra("message", s1);//跳转并且传递过去值,健值对形式;
intent.putExtra("jsonfire", s4);
intent.putExtra("jsonto", s2);
intent.putExtra("json_there", s3);
//启动Intent
startActivityForResult(intent, 1000);
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {//这个非常重要的接收返回过来的数据值onActivityResult函数;
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 1000 && resultCode == 1001) {
String result = data.getStringExtra("result");
json_one.setText(result);
String fire = data.getStringExtra("fire");
jsonfire.setText(fire);
String listool = data.getStringExtra("listool");
json_to.setText(listool);
String noneres1 = data.getStringExtra("noneres1");
json_there.setText(noneres1);
}
}
}
现在主界面第一个界面功能传递做好了,然后就是第二个界面了。
public class NameActivity extends AppCompatActivity implements View.OnClickListener {
private LinearLayout back,imei_tone;
private EditText et_name,sms_name,email_name;
private TextView android_none;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_name);
back = findViewById(R.id.back);
et_name = findViewById(R.id.et_name);//定义控件初始化
sms_name = findViewById(R.id.sms_name);
email_name= findViewById(R.id.email_name);
imei_tone= findViewById(R.id.imei_tone);
android_none= findViewById(R.id.android_none);
back.setOnClickListener(this);//点击返回数据到a界面
Intent intent = getIntent();//接收a跳转过来的值
String message = intent.getStringExtra("message");
et_name.setText(message);//a界面传递过来的值显示到控件上;
String jsonfire = intent.getStringExtra("jsonfire");
sms_name.setText(jsonfire);
String jsonto = intent.getStringExtra("jsonto");
email_name.setText(jsonto);
String json_there = intent.getStringExtra("json_there");
android_none.setText(json_there);
}
@Override
public void onClick(View v) {
switch (v.getId()){
//底部按钮事件点击切换
case R.id.back:
String result = et_name.getText().toString();//获取到更改之后的,或者可以说是当前b界面的控件值;
String result2 = sms_name.getText().toString();
String result3 = email_name.getText().toString();
String result1 = android_none.getText().toString();
Intent intent = new Intent();
intent.putExtra("result", result);//此时返回b控件上的值到a界面;
intent.putExtra("fire", result2);
intent.putExtra("listool", result3);
intent.putExtra("noneres1", result1);
setResult(1001, intent);//通过这个1001指令发送
finish();//关闭当前界面
break;
}
}
nice,大功告成!android返回传值可以顺利的发送和接收到数据了,若对您有所帮助,请点个赞或关注下,还会继续努力更新文章,会把自己所做所学到的实践操作都分享给大家,还有不足之处,尽请谅解!有问题可联系博主,感谢您的阅读!
