这周我学会了安卓如何进行数据共享，android数据进行共享的代码如下
package com.dongnaoedu.chapter04;

 

import androidx.appcompat.app.AppCompatActivity;

 

import android.content.Intent;

import android.os.Bundle;

import android.view.View;

import android.widget.TextView;

 

import com.dongnaoedu.chapter04.util.DateUtil;

 

public class ActSendActivity extends AppCompatActivity implements View.OnClickListener {

 

    private TextView tv_send;

 

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_act_send);

        tv_send = findViewById(R.id.tv_send);

        findViewById(R.id.btn_send).setOnClickListener(this);

    }

 

    @Override

    public void onClick(View v) {

        Intent intent = new Intent(this, ActReceiveActivity.class);

        // 创建一个新包裹

        Bundle bundle = new Bundle();

        bundle.putString("request_time", DateUtil.getNowTime());

        bundle.putString("request_content", tv_send.getText().toString());

        intent.putExtras(bundle);

        startActivity(intent);

    }

}

　　

package com.dongnaoedu.chapter04;

 

import androidx.appcompat.app.AppCompatActivity;

 

import android.os.Bundle;

import android.widget.TextView;

 

public class ActReceiveActivity extends AppCompatActivity {

 

    private TextView tv_receive;

 

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_act_receive);

        tv_receive = findViewById(R.id.tv_receive);

        // 从上一个页面传来的意图中获取快递包裹

        Bundle bundle = getIntent().getExtras();

        String request_time = bundle.getString("request_time");

        String request_content = bundle.getString("request_content");

        String desc = String.format("收到请求消息：\n请求时间为%s\n请求内容为%s", request_time, request_content);

        tv_receive.setText(desc);

    }

}
