android - エディットテキスト値をアダプタークラスに渡す方法

Question

以下のアクティビティからテキスト値を TextAdapter クラスに渡したいと思います。
public class SecondActivity extends Activity {

EditText et1;
TextView t1,t2;
Button b1,b2;
String result;
Context context = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sec);
et1 = (EditText) this.findViewById(R.id.editText1);
t1 = (TextView) this.findViewById(R.id.textView1);
t2 = (TextView) this.findViewById(R.id.textView2);
b1 = (Button) this.findViewById(R.id.button1);
b2 = (Button) this.findViewById(R.id.button2);
b1.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
t2.setText(et1.getText());
}
});
b2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent i = new Intent(v.getContext(),ThirdActivity.class);
startActivity(i);
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

この値は、配列 public class TextAdapter extends PagerAdapter{ に追加されます。

    private String[] textViewer = new String[]{
"Hai"--------------(Here i want the edit text value)
};
public TextAdapter (Context context){
this.context= context;
}

@Override
public int getCount() {
return textViewer.length;
}

@Override
public boolean isViewFromObject(View view, Object object) {
return view==((TextView)object);
}
public Object instantiateItem(ViewGroup container, int position) {
TextView textView = new TextView(context);
textView.setText(textViewer[position]);
((ViewPager) container).addView(textView, 0);
return textView;
}

@Override
public void destroyItem(ViewGroup container, int position, Object object) {
((ViewPager) container).removeView((TextView) object);
}

}
