如何检查，如果我的按钮被点击在另一个活动？ [英] How to check if my button is clicked in another activity?

问题描述

我想这取决于在点击另一个按钮布局让文本（我有按钮1和按钮2）我不能做一个if语句语句，因为它不承认的按钮。

I want to get text depending on which button in another layout in clicked (I have button 1 and button 2) I can't do a if clause statement because it doesn't recognize the buttons.

推荐答案

您可以设置不同的一些变量值不同（如，如果你点击按钮1让其值设为1或者2）传递整数变量作为意图在previous活动，并使用GetExtras（）来检索整型变量...现在使用的IF条件来确定哪个按钮被点击

You could set different set some variable to different values(eg. if you click on button1 make its value as 1 or else 2) pass that integer variable as an intent to the previous activity and use GetExtras() to retrieve the integer variable...now use the IF condition to determine which button was clicked

public void onClick(View view) {
int code;

switch(view.getId()){
case R.id.button1:
 code=1;
break;

case R.id.button2:
 code=2;
break;
}
    Intent i = new Intent(this, ResultActivity.class);
    i.putExtra("yourcode", code);
    startActivityForResult(i, REQUEST_CODE);
  }

现在回到你的老活动中使用

Now back to your old activity use

getIntent（）getExtras（你的code）的toString（）。检索它

getIntent().getExtras("yourcode").toString(); to retrieve it
