为什么将 textInput 内容传递给 string 到 ArrayList

Why pass textInput content to string into ArrayList

我想从使用 TextInputLayout 制作的表单传递值,但 Android Studio 将我的内容检测为 INT。 我将 activity 的完整 class 以及视图放在 .xml 中以确定问题

import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.provider.MediaStore;
import android.support.design.widget.TextInputEditText;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
import com.prosegma.rso.R;
import java.io.File;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Date;

public class AccionActivity extends AppCompatActivity {

    ImageView imageView;
    private Context activity;
    private String[]header={"Campo","Respuesta"};
    private String shortText="RSO PROSEGMA";
    private String longText="Eliminamos Riesgos Sumamos Valor";
    private AccionPdf accionPdf;



    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_accion);


        Button btnCamera1 = (Button)findViewById(R.id.BtnCamera1);
        imageView = (ImageView)findViewById(R.id.reporte1);
        btnCamera1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                startActivityForResult(intent,0);
            }
        });


        Date date = new Date();
        String timeStamp = new SimpleDateFormat("dd/MM/yyyy").format(date);

        accionPdf=new AccionPdf(getApplicationContext());
        accionPdf.openDocument();
        accionPdf.addMetaData("Reporte","Acción Insegura","www.prosegma.com");
        accionPdf.addTitle("Reporte Acción Insegura","RSO Prosegma"," " +timeStamp);
        accionPdf.addParagraph(shortText);
        accionPdf.addParagraph(longText);
        accionPdf.createTable(header,getClients());
        accionPdf.closeDocument();
    }

    TextInputEditText Nreport = (TextInputEditText) findViewById(R.id.nReporta);



    private ArrayList<String[]>getClients(){
        ArrayList<String[]>rows=new ArrayList<>();
        rows.add(new String[]{"Nombre de quien reporta", Nreport });
        rows.add(new String[]{"Nombre del trabajador","No"});
        rows.add(new String[]{"Empresa contratista","ju"});
        rows.add(new String[]{"Medidas Necesarias","hu"});
        return rows;
    }


    public void pdfAccion(View view)
    {
accionPdf.verReporteAccion();
    }

    public void enviarA(View view) {

        Intent email = new Intent(Intent.ACTION_SEND);
        email.putExtra(Intent.EXTRA_EMAIL, "receiver_email_address");
        email.putExtra(Intent.EXTRA_SUBJECT, "subject");
        email.putExtra(Intent.EXTRA_TEXT, "email body");
        Uri uri = Uri.fromFile(new File(android.os.Environment.getExternalStorageDirectory(), "pdfFileName"));
        email.putExtra(Intent.EXTRA_STREAM, uri);
        email.setType("application/pdf");
        email.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        getActivity().startActivity(email);
    }

    public Context getActivity() {
        return activity;
    }
}

我用 activity 更新了出版物,我试图通过 EditText 更改 InputTextLayout 但情况是一样的,它抛出一个不兼容错误。

这一行在 OnCreate(Bundle savedInstanceState) 方法之外。这就是它抛出 null 的原因。应该是这样的

public class MainActivity extends AppCompatActivity {
TextInputEditText Nreport;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

  //  Button btnCamera1 = (Button)findViewById(R.id.BtnCamera1);
   // imageView = (ImageView)findViewById(R.id.reporte1);



    Date date = new Date();
    String timeStamp = new SimpleDateFormat("dd/MM/yyyy").format(date);
     Nreport = (TextInputEditText) findViewById(R.id.nReporta);
   getClients();
}





private ArrayList<String[]> getClients(){
    ArrayList<String[]>rows=new ArrayList<>();
    rows.add(new String[]{"Nombre de quien reporta", Nreport.getText().toString() }); // get text like this
    rows.add(new String[]{"Nombre del trabajador","No"});
    rows.add(new String[]{"Empresa contratista","ju"});
    rows.add(new String[]{"Medidas Necesarias","hu"});
    return rows;
}
