In programming, "activity跳转到_转到定义" typically refers to navigating from one activity (Activity) to another in mobile app development, such as on the Android platform. This involves using intents and managing the lifecycle of activities.

In Android development, activity transitions are a common operation. Below, we will discuss how to implement the transition from one activity to another.

1. Create a new Activity

We need to create a new activity that will be used as the target activity, i.e., the activity we want to navigate to from the current activity.

public class TargetActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_target);
    }
}

2. Register the new Activity in the Manifest

After creating the new activity, we need to register it in the AndroidManifest.xml file.

<activity android:name=".TargetActivity"></activity>

3. Transition from the source Activity to the target Activity

In the source Activity, we can use an intent to achieve the transition between activities.

Intent intent = new Intent(SourceActivity.this, TargetActivity.class);
startActivity(intent);

4. Pass data

If you need to pass data between activities, you can use the putExtra method of the Intent.

Intent intent = new Intent(SourceActivity.this, TargetActivity.class);
intent.putExtra("key", "value");
startActivity(intent);

In the target Activity, you can retrieve the passed data using getIntent().getStringExtra() method.

String value = getIntent().getStringExtra("key");

These are the basic steps for transitioning from one activity to another. In actual development, you may need to handle more complex logic, such as launch modes, tasks, and backstacks.

Below is a simple description of the situation where you "跳转" from one activity to another defined as "转到定义":

This description serves as a template, and you can modify the parameters and example values according to your specific needs. In real-world applications, you may need to decide which data to pass and how to perform the transition based on your specific business logic and requirements.
