传递方：

//点击btn_sub传递 fieldHeight.getText()和 fieldWeight.getText()

private void setListeners()

{

btn_sub.setOnClickListener(calrBMI);

}

private OnClickListener calrBMI = new OnClickListener()

{

public void onClick(View v)

{

Intent intent = new Intent();

Bundle bundle = new Bundle();

bundle.putString("key_height", fieldHeight.getText().toString());

bundle.putString("key_weight", fieldWeight.getText().toString());

intent.setClass(ActivityMain.this,Report.class);

intent.putExtras(bundle);

startActivity(intent);

}

};

接收方：

Bundle bundle = new Bundle();

bundle = this.getIntent().getExtras();

double height = Double.parseDouble(bundle.getString("key_height"))/100;

double weight = Double.parseDouble(bundle.getString("key_weight"));
