可以setEnabled（）函数可以被覆盖，如果是这样如何？(Can setEnabled() Function can be overidden,if so how?)

可以setEnabled（）函数可以被覆盖，如果是这样如何？(Can setEnabled() Function can be overidden,if so how?) public class AppaSwitch extends AppCompatImageButton implements View.OnClickListener { @Override public void onClick(View v) { } }

像上面的code有一种方法来覆盖android setEnabled()函数。下面是一个例子，但我看不到像这样的方法

public class AppaSwitch extends AppCompatImageButton implements View.OnEnabled { @Override public void OnEnabled(View v) { } }

或者有没有其他方法可以做到这一点？

public class AppaSwitch extends AppCompatImageButton implements View.OnClickListener { @Override public void onClick(View v) { } }

Like the above code is there a way to override setEnabled() function in android.The below is an example but I see no method like this

public class AppaSwitch extends AppCompatImageButton implements View.OnEnabled { @Override public void OnEnabled(View v) { } }

Or is there any alternate way of doing this ?

最满意答案

setEnabled（）是View类的方法， AppCompatImageButton已经扩展了View Class，所以你可以直接覆盖这里所做的：

public class AppaSwitch extends AppCompatImageButton { @Override public void setEnabled(boolean enabled) { //your piece of code //if you want to remove below line to remove the function of super class. super.setEnabled(enabled); } }

setEnabled() is the method of View class and AppCompatImageButton already extends View Class, so you can directly override as done here:

public class AppaSwitch extends AppCompatImageButton { @Override public void setEnabled(boolean enabled) { //your piece of code //if you want to remove below line to remove the function of super class. super.setEnabled(enabled); } }
