Android Fragment向另一个Activity传值

时间：2023-11-20 12:46:26

1.Fragment内：

Intent intent=new Intent(getActivity(),ShowDataActivity.class); //参数1:Fragment所依存的Activity,参数2：要跳转的Activity

Bundle bundle = new Bundle();

bundle.putString("queryresult",queryResultStr); //放入所需要传递的值

intent.putExtras(bundle);

getActivity().startActivity(intent); //这里一定要获取到所在Activity再startActivity()；

2.ShowDataActivity.class

package com.example.lucky.zjzyhq3;

import android.content.Intent;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.view.View;

import android.widget.Button;

import android.widget.TextView;

import android.widget.Toast;

import com.bin.david.form.core.SmartTable;

import com.bin.david.form.data.table.MapTableData;

public class ShowDataActivity extends AppCompatActivity {

    SmartTable table;

    Button btSD_exit;

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_show_data);

        //获取从MyFragment_basicMessage中传过来的值

        Intent intent=getIntent();

        String queryResultStr=intent.getStringExtra("queryresult");

        table =findViewById(R.id.table);

        btSD_exit=findViewById(R.id.btSD_exit);

        if(queryResultStr.equals("[]")){

            Toast.makeText(ShowDataActivity.this,"无匹配查询结果",Toast.LENGTH_LONG).show();

        }else {

            MapTableData tableData = MapTableData.create("表格名",JsonHelper.jsonToMapList(queryResultStr));

            table.setTableData(tableData);

        }

        btSD_exit.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View v) {

                Intent intent1=new Intent(ShowDataActivity.this,MainScreenActivity.class);

                startActivity(intent1);

            }

        });

        System.out.println(queryResultStr);

    }

}
