}
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"));
