b1.setOnClickListener(new OnClickListener() {

在manifest中添加Activity  <activity android:name=".Hwhxt" />

@Override

public void onClick(View v) {

.// 显示方式声明Intent,直接启动SecondActivity

.Intent intent = new Intent(FirstActivity.this,SecondActivity.class);

 intent.putExtra("value", xmlMessage);//传的值

 intent.setClass(AttributeQuery.this, Hwhxt.class);

 //AttributeQuery.this.startActivity(intent2);

startActivity(intent);

}

});

接受值：

        Intent intent = getIntent();

        String xmlMessage = intent.getStringExtra("value");
