你可以试试下面的代码:

Intent myIntent = new Intent();
FirstActivity.this.SecondActivity(myIntent);

当用户点击按钮时，直接在XML中，就像这样:

<Button
         android:id="@+id/button"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:text="TextButton"
         android:onClick="buttonClickFunction"/>

使用属性android:onClick我们声明方法名必须出现在父活动上。所以我必须在我们的活动中创建这个方法，像这样:

public void buttonClickFunction(View v)
{
            Intent intent = new Intent(getApplicationContext(), Your_Next_Activity.class);
            startActivity(intent);
}

Intent i = new Intent(firstactivity.this, secondactivity.class);
startActivity(i);

点击按钮时:

loginBtn.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {
        Intent intent= new Intent(getApplicationContext(), NextActivity.class);
        intent.putExtra("data", value); //pass data
        startActivity(intent);
    }
});

从nex战术vity.class接收额外的数据:

Bundle extra = getIntent().getExtras();
if (extra != null){
    String str = (String) extra.get("data"); // get a object
}

    Intent in = new Intent(getApplicationContext(),SecondaryScreen.class);    
    startActivity(in);

    This is an explicit intent to start secondscreen activity.

 imageView.setOnClickListener(v -> {
// your code here
        });
