单击时更改按钮颜色

Question

OK, when I use setBackground on a button, the button no longer shows any feedback when its clicked. How can I fix this. I just want the button to get darker or some type of feedback so the user knows it was clicked.

Hope this makes sense!

Answer 1

Create this drawable and bind it to button background

<selector 
xmlns:android="http://schemas.android.com/apk/res/android">
 <item android:state_focused="true" android:state_pressed="false" android:drawable="@drawable/YOURIMAGE" />
 <item android:state_focused="true" android:state_pressed="true" android:drawable="@drawable/gradient" />
 <item android:state_focused="false" android:state_pressed="true" android:drawable="@drawable/gradient" />
 <item android:drawable="@drawable/YOURIMAGE" />
 </selector>

Apply it to button

android:background="@drawable/button"

You need to create a selector inside the XML and have it linked to state_pressed = "true". Inside of the item, you can specify the shape of the object. I've linked to the Android developer site so you can see other options available as well.

        <item android:state_pressed="true">
            <shape>
                <solid android:color="#73E5E4D7" />
            </shape>
        </item>
        <item>
            <shape>
                <solid android:color="#E6E5E4D7" />
            </shape>
        </item>

hope this works well. first assign your button into a button type reference in your activity class. ex: newBtn=(Button) findViewById(R.id.yourButton);

after that set an listener to that button.

  yourButton.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            yourButton.setBackgroundColor(int colorCode);
        }
    });
