日食开普勒如何添加按钮以连接到另一种形式

Question

I have 2 files: main_activity.xml and vision.xml. I made a button in main_activity.xml

How can I open the vision.xml using button? Can you give me codes for MainActivity.java?

Answer 1

In your MainActivity.java add a public method as follows

public void startVision(View view){
    Intent intent = new Intent(this,Vision.class);
    startActivity(intent);
}

then in your main_activity.xml make your Button definition look like as follow

<Button
    ...
    android:onClick="startVision" />
