          tableRow = new TableRow(getApplicationContext());

          textView5 = new TextView(getApplicationContext());
          textView5.setText(c.getString(c.getColumnIndex("fname")));


          textView6 = new TextView(getApplicationContext());
          textView6.setText(c.getString(c.getColumnIndex("mname1")));

          textView7 = new TextView(getApplicationContext());
          textView7.setText(c.getString(c.getColumnIndex("mname2")));

          textView8 = new TextView(getApplicationContext());
          textView8.setText(c.getString(c.getColumnIndex("lname")));

          textView9 = new TextView(getApplicationContext());
          textView9.setText(c.getString(c.getColumnIndex("email")));

          textView5.setPadding(10, 10, 10, 10);
          textView6.setPadding(10, 10, 10, 10);
          textView7.setPadding(10, 10, 10, 10);
          textView8.setPadding(10, 10, 10, 10);
          textView9.setPadding(10, 10, 10, 10);

          tableRow.addView(textView5);
          tableRow.addView(textView6);
          tableRow.addView(textView7);
          tableRow.addView(textView8);
          tableRow.addView(textView9);



          tableLayout.addView(tableRow);
          c.moveToNext();


        textView5.setClickable(true);

        textView5.setOnClickListener(new View.OnClickListener() {



            @Override
            public void onClick(View arg0) {

                // TODO Auto-generated method stub

                String ett1 = textView5.getText().toString();/* Error is here*/
                String data1 = textView5.getText().toString();/*error is here*/


                Intent intent = new Intent(MainActivity.this , savedata.class);

                intent.putExtra("ett1", data1 + "");



                startActivity(intent);


            }
        });

      }  










public class savedata extends Activity

{

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

        TextView txt2 = (TextView) findViewById(R.id.textView2);
        txt2.setText(getIntent().getStringExtra("ett1"));


}
}

Answer 1

Your Activity :

Intent i=new Intent(Urclassname.this,secondPage.class);
i.putExtra("Id", stringdata);


In Next Page :(in onCreate Method)
Intent intent = getIntent();
String id = intent.getStringExtra("Id");

Android中的TextView初始化。
