Question

我试图在一个活动（activity1）中的android中的EditTexts中接收两个输入。这两个输入是一个表的维度，我在另一个活动（activity2）中动态创建。我尝试使用Bundles以及简单的意图。我正在接受一个维度而无法收到另一个维度。第二维自动获取第一维的值。

如何在android中发送和接收多个值。请帮忙。

我的第一项活动如下

public final static String EXTRA_MESSAGE = "abc";
public final static String EXTRA_MESSAGE2 = "abc";
       Intent intent = new Intent( c , CreateTimeTable.class);
                    Bundle bun = new Bundle();
                    EditText editText = (EditText) findViewById(R.id.nlec);
                    EditText editText2 = (EditText) findViewById(R.id.nday);
                    String message = editText.getText().toString();
                    String message2 = editText2.getText().toString();
                    bun.putString(EXTRA_MESSAGE, message);
                    bun.putString(EXTRA_MESSAGE2, message2);
                    intent.putExtras(bun);
                    startActivity(intent);

第二项活动是

setContentView(R.layout.activity_create_time_table);

    int j;
    Intent intent = getIntent();
    Bundle bun = this.getIntent().getExtras();
    String message = bun.getString(NewTT.EXTRA_MESSAGE);
    String message2 = bun.getString(NewTT.EXTRA_MESSAGE2);
    int lec = Integer.parseInt(message);
    int day =  Integer.parseInt(message2);

变量lec获取与日相同的值，无论输入是什么

Answer 1

Intent intent= new Intent(YourActivity.this, SecondActivity.class);
intent.putExtra("key1", valuetopass_1);
intent.putExtra("key2", valuetopass_2);
startActivity(intent);

// Get values in second activity

SecondActivity.java

Intent in = getIntent();
String value1 = in.getStringExtra("key1");
String value2 = in.getStringExtra("key2");

Answer 2

Intent myIntent = new Intent(mycurentActivity.this, secondActivity.class);
myIntent.putExtra("key", myEditText1.Text.toString());
myIntent.putExtra("key1", myEditText2.Text.toString());
myIntent.putExtra("key2", myEditText3.Text.toString());
startActivity(myIntent); 


String text = myIntent.getStringExtra("key1");
String text1 = myIntent.getStringExtra("key2");
String text3 = myIntent.getStringExtra("key");

Answer 3

public final static String EXTRA_MESSAGE = "abc";
public final static String EXTRA_MESSAGE2 = "abc";

变量lec获取与日相同的值，无论输入是什么

键是相同的，所以值是相同的。使密钥不同。

Answer 4

发送意图时：

intent.putExtra("YOUR-KEY_1", "data_here");
intent.putExtra("YOUR-KEY_2", "data_here");

收到意图时：

if(getIntents()!= null){
String data1 = getIntents().getExtras().getString("YOUR-KEY_1");
String data2 = getIntents().getExtras().getString("YOUR-KEY_2");
}

就是这样！：）
