Android StateListDrawable pressed 상태가 항상 마지막으로 표시됨

Question

사용자 지정 단추가 있고 프로그래밍 방식으로 누름 및 기본 색을 변경했습니다.

public class CustomApplicationButton extends Button { 

public CustomApplicationButton(Context context) { 
    this(context, 0, 0, 0); 
} 

public CustomApplicationButton(Context context, int topDrawableResId, int outlineDefaultColorId, int outlinePressedColorId) { 
    super(context); 

    // set width and height 
    LinearLayout.LayoutParams params = new LayoutParams(
      context.getResources().getDimensionPixelSize(R.dimen.sr_application_button_width), 
      context.getResources().getDimensionPixelSize(R.dimen.sr_application_button_height)); 
    setLayoutParams(params); 

    // set drawable top icon 
    if (topDrawableResId != 0) { 
     setCompoundDrawablesWithIntrinsicBounds(0, topDrawableResId, 0, 0); 
    } 

    // set background and outline color 

    int strokeWidth = context.getResources().getDimensionPixelSize(R.dimen.sr_launcher_button_stroke_size); 

    // unpressed state drawable 
    LayerDrawable defaultLayers = (LayerDrawable) context.getResources().getDrawable(
      R.drawable.btn_launcher_shape_default); 
    GradientDrawable defaultShapeOutline = (GradientDrawable) defaultLayers.findDrawableByLayerId(R.id.outline_default); 
    defaultShapeOutline.setStroke(strokeWidth, context.getResources().getColor(outlineDefaultColorId)); 

    // pressed state drawable 
    LayerDrawable pressedLayers = (LayerDrawable) context.getResources().getDrawable(
      R.drawable.btn_launcher_shape_pressed); 
    GradientDrawable pressedShapeOutline = (GradientDrawable) pressedLayers.findDrawableByLayerId(R.id.outline_pressed); 
    pressedShapeOutline.setStroke(strokeWidth, context.getResources().getColor(outlinePressedColorId)); 

    // set states 
    StateListDrawable states = new StateListDrawable(); 
    states.addState(new int[] {android.R.attr.state_pressed}, pressedLayers); 
    states.addState(new int[] { }, defaultLayers); 

    // set background 
    this.setBackground(states); 
}

다음

, 내부에있는 LinearLayout을 가지고 내 활동이 버튼을 추가했습니다.

public class MainActivity extends Activity { 

private LinearLayout applicationPanel; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    applicationPanel = (LinearLayout) findViewById(R.id.application_panel); 
    ssPanel = (LinearLayout) findViewById(R.id.ss_panel); 

    CustomApplicationButton btnLauncherApp = new CustomApplicationButton(this, R.drawable.ic_application, 
      R.color.application_green_default_color, R.color.application_green_pressed_color); 
    btnLauncherApp.setText("Button 1"); 
    applicationPanel.addView(btnLauncherApp); 

    btnLauncherApp = new CustomApplicationButton(this, R.drawable.ic_camera, 
      R.color.camera_blue_default_color, R.color.camera_blue_pressed_color); 
    btnLauncherApp.setText("Button 2"); 
    applicationPanel.addView(btnLauncherApp); 

    btnLauncherApp = new CustomApplicationButton(this, R.drawable.ic_browser, 
      R.color.browser_gray_default_color, R.color.browser_gray_pressed_color); 
    btnLauncherApp.setText("Button 3"); 
    applicationPanel.addView(btnLauncherApp); 

} 

}

내 문제는 3 버튼은 다른 기본 획 색상을 가지고 있지만 누르면 획 색상은 항상 마지막에 추가 버튼 색상 것입니다.

요약하면 다음과 같습니다.

으로 명확하게 문서에 언급 된 :

"Note: changing this property will affect all instances of a drawable loaded from a resource. It is recommended to invoke mutate() before changing this property." 

당신이 모든 setStroke 메소드() 이전의 mutate()를 호출한다면, 문제 것 해결되다.

defaultShapeOutline.mutate(); 
defaultShapeOutline.setStroke(strokeWidth, context.getResources().getColor(outlineDefaultColorId));
