Intent 问题。传输数据过程的错误 扔掉我所有的C币了。

Question

package zc.gdzj.ztext;
import zc.gdzj.ztextsqlite.*;
import android.app.Activity;
import android.content.Intent;
import android.database.Cursor;
import android.os.Bundle;
import android.text.method.ScrollingMovementMethod;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

public class showActivity extends Activity {

private EditText searchEditText;
private Button sureButton;
private TextView showTextView;
private int i=0;
@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.list_activity);
    DBAdapter db = new DBAdapter(this);
    sureButton=(Button)findViewById(R.id.sureButton);
    searchEditText=(EditText)findViewById(R.id.findEditText);
    showTextView=(TextView)findViewById(R.id.showTextview);
    showTextView.setMovementMethod(ScrollingMovementMethod.getInstance());
    db.open();
    Cursor c = db.getAllTitles();
    if (c.moveToFirst())
    {
    do {
    DisplayTitle(c,i);
    i++;
    } while (c.moveToNext());
    }
    db.close();

    sureButton.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent intent=new Intent();
            intent.putExtra("id", searchEditText.getText().toString());
            intent.setClass(showActivity.this, singleActicity.class);
            startActivity(intent);
        }
    });
}
public void DisplayTitle(Cursor c,int i)
{
    showTextView.append(c.getString(0)+":TITLE: " +c.getString(1)+ "\n" +c.getString(2)+"\n");
}

}
求问这段程序中Intent 使用问题所在。这是第二个界面不是第一个。第二个Activity 跳转到第三个的时候直接歇火了。

Answer 1

我解决了，是因为我在注册文件中写错了一个字母。这个传输没有问题。谢谢
