求大神求解脱 来看看我的代码

import android.view.View;
import android.view.View.OnClickListener;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;

public class AlterPassword extends Activity {
	private TextView text;
	EditText edit1,edit2,edit3;
	ImageView image;
	String jiu;
	String xin1;
	String xin2;
	String username;
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		setContentView(R.layout.alter);
		edit1=(EditText)findViewById(R.id.alter_edit1);
		edit2=(EditText)findViewById(R.id.alter_edit2);
		edit3=(EditText)findViewById(R.id.alter_edit3);
                image.setOnClickListener(new OnClickListener() {
			
			@Override
			public void onClick(View v) {
                                 System.out.println(xin1+"  "+xin2);
}
}
}
}

为什么我在editview输入框输入了数字 为什么xin1 hexin2 是空值
而edit2.getText().toString().trim()     (edit3.getText().toString().trim())是正常的

求解答啊！！！！！！！！！！！！！

ExpandableListView 给这东西 设置一个高度, 把 ExpandableListView 组件的高度 定死了, 不要  warp_content
