如何以编程方式更改radiobutton

中的popupmenu颜色

private void showPopupMenu(View view) {
    PopupMenu popupMenu = new PopupMenu(getContext(), view);
    popupMenu.getMenuInflater().inflate(R.menu.menu_publish_more_popup, popupMenu.getMenu());
    MenuItem postItem = popupMenu.getMenu().findItem(R.id.action_post);
    postItem.setChecked(true);
    RadioButton radioButton = (RadioButton) (postItem.getActionView());
    if (Build.VERSION.SDK_INT >= 21) {
        ColorStateList colorStateList = new ColorStateList(
                new int[][]{
                        new int[]{-android.R.attr.state_enabled}, //disabled
                        new int[]{android.R.attr.state_enabled} //enabled
                },
                new int[]{
                        Color.GREEN
                        , Color.RED
                }
        );
        radioButton.setButtonTintList(colorStateList);//set the color tint list
        radioButton.invalidate(); //could not be necessary
    }
    popupMenu.show();
}

Answer 1

首先定义colorstatelist

ColorStateList colorStateList = new ColorStateList(
                new int[][]{
                        new int[]{android.R.attr.state_enabled} //enabled
                },
                new int[] {getResources().getColor(R.color.colorPrimary) }
        );

然后分配

AppCompatRadioButton radioButton = (AppCompatRadioButton) findViewById(R.id.rb);
radioButton.setSupportButtonTintList(colorStateList);

AppCompatCheckBox cbSelected = (AppCompatCheckBox) findViewById(R.id.cbSelected);
cbSelected.setSupportButtonTintList(colorStateList);

或者如果这不起作用，那么使用它：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    male.setButtonTintList(ColorStateList.valueOf(ContextCompat.getColor(ReservationContact.this, R.color.background)));
}
male.setHighlightColor(getResources().getColor(R.color.background));

试试这段代码：

PopupMenu popupMenu = new PopupMenu(this, view);
        popupMenu.getMenuInflater().inflate(R.menu.menu_publish_more_popup, popupMenu.getMenu());
         popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {  
                     public boolean onMenuItemClick(MenuItem item) {  
                      if(item.getTitle().equals("Create Post")){
    if(Build.VERSION.SDK_INT>=21)
    {

        ColorStateList colorStateList = new ColorStateList(
                new int[][]{

                        new int[]{-android.R.attr.state_enabled}, //disabled
                        new int[]{android.R.attr.state_enabled} //enabled
                },
                new int[] {

                        Color.WHITE//disabled
                        ,Color.RED//enabled

                }
            );                       


        radio.setButtonTintList(colorStateList);//set the color tint list
        radio.invalidate(); //could not be necessary
    }
    } 
                      return true;  
                     }  
                    });  

                    popup.show();//showing popup menu

Answer 3

你可以尝试，

MenuItem menuitem=popupMenu.getMenu().findItem(R.id.action_post);
RadioButton radioButton=  (RadioButton)(MenuItemCompat.getActionView(menuitem));//menuitem.getActionView();
radioButton.setButtonTintList(colorstateList);

在您的菜单中，添加actionViewClass，

<item
android:id="@+id/action_post"
android:actionViewClass="android.widget.RadioButton"
/>

您的colorStateList应该是，

 ColorStateList colorStateList = new ColorStateList(
            new int[][]{
                    new int[]{}, //otherwise for all cases
                    new int[]{android.R.attr.state_checked} //checked
            },
            new int[]{
                    Color.GREEN,Color.RED
            }
    );
