ANDROID组按钮

Question

在主视图中，我有12个按钮。但我会改变这一点。我会做一个预先屏幕。在该视图中，将有4个按钮，当单击其中一个按钮时，将显示主视图中的3个按钮。

我不想为这个单独的观点制作4个观点。必须有办法。

我的按钮：

btnUni.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Log.e(TAG,"ButtonUni clicked");//d.deleteOldEvents();
           // new RetrieveEvents("Uni");
            Intent intent = new Intent(MainActivity.this,ListEvents.class);
            intent.putExtra("Type","Uni");

              //kaldırılabilir bu
            Toast.makeText(getApplication(), "LUTFEN BEKLEYINIZ... UNIVERSITE ETKINLIKLERI GOSTERILMEK ICIN HAZIRLANIYOR...",
                    Toast.LENGTH_LONG).show();

            Log.e(TAG,"Intent created, now executing");
            startActivity(intent);
        }
    });

    btnConcert.setOnClickListener(new View.OnClickListener() {
        @Override

例如，屏幕前会显示art。点击后，将显示艺术剧院展览按钮。

Answer 1

将您的12个按钮分为四个独立的布局，通过点击之前的屏幕按钮设置这些布局的可见性。

Answer 2

尝试此方法，在xml文件中更新此按钮

<Button
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="UNIVERSITE"
    android:id="@+id/btn_uni"
    android:onClick="btn_uni"
    android:layout_alignParentTop="true"
    android:layout_alignParentLeft="true"
    android:layout_alignParentStart="true" />

在Java文件中使用onclick方法 无需初始化，

public void btn_uni(view View){
   // your code goes here
}
