Activity间用Intent和Bundle传递参数

    Activity跳转，数据传送，就是它了：intent、bundle，简单最好；

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"));
