java - 如何在android中的活动之间传输布尔值？

Question

这就是我目前的做法，但它只是强制关闭应用程序。

在第一个活动中

Intent myIntent = new Intent(Input.this, results.class);
    myIntent.putExtra("perfect", rig);
    startActivity(myIntent);`

我想转移到的活动

    Boolean lovers = getIntent().getExtras().getBoolean("perfect");

Answer 1

正如文档所说，功能是getBooleanExtra

Boolean lovers = getIntent().getExtras().getBooleanExtra("perfect");

Answer 2

我不确定接受的答案::但我认为应该是

Boolean lovers = getIntent().getExtras().getBoolean("perfect");

Answer 3

您可以在发送方尝试此操作：

MyModel model = new MyModel();

 //1. using constructor
    Boolean blnObj1 = new Boolean(model.getBooleanStatus()); // This //getBooleanStatus will return 'boolean' value

    //2. using valueOf method of Boolean class. This is a static method.
    Boolean blnObj2 = Boolean.valueOf(model.getBooleanStatus());
  }

Intent targetIntent = new Intent(MyCalass.this, TargetClass.class);
targetIntent.putExtra("STATUS", new Boolean(model.getBooleanStatus()));
targetIntent.putExtra("STATUS", Boolean.valueOf(model.getBooleanStatus()));
startActivity(targetIntent);

接收方：

Intent receiverIntent = getIntent().getBoolean("STATUS");
