Android - 单击按钮时使用 If 语句调用 function
[英]Android - Using If statement when button is clicked to call a function
问题描述
当我更改应用程序的主题时，我有多个 onClickListeners 被调用。 我正在使用图像和 colors 来更改我的应用程序的背景，并且图像和 colors 也会根据您选择的主题而改变。 每当我更改背景图像或颜色时，都会在 OnCreate 中调用两个单独的函数，即 setLayoutBGColor() 和 setLayoutBGImage()。 问题是我需要使用 if 语句来检查用户是否单击了 colors 或图像之一，然后基于此调用 function。 我无法添加完整的 onCreate function 因为它超出了字数限制
CreateNote class OnCreate function：
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.layout_create_note);
coordinatorLayout = findViewById(R.id.layoutBGcolor);
layoutCopyNote = findViewById(R.id.copyNote);
bgColorView = findViewById(R.id.bgColorImageView);
theme = Utils.getTheme(this);
if(theme == 1) {
selectedNoteColor = "#333333";
}
else{
selectedNoteColor = "#FFFFFF";
}
selectedColorIndex = 0;
selectedImagePath = "";
selectedNoteBgImage = "";
selectedImageIndex = 0;
initMisc();
//add an if else statement
setLayoutBGColor();
setLayoutBGImage();
}
InitMisc Function 提到了所有的听众：
private void initMisc() {
layoutMisc = findViewById(R.id.layoutMisc);
bottomSheetBehavior = BottomSheetBehavior.from(layoutMisc);
layoutMisc.findViewById(R.id.textMisc).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (bottomSheetBehavior.getState() != BottomSheetBehavior.STATE_EXPANDED) {
bottomSheetBehavior.setState(BottomSheetBehavior.STATE_EXPANDED);
} else {
bottomSheetBehavior.setState(BottomSheetBehavior.STATE_COLLAPSED);
}
}
});

两个功能：
private void setLayoutBGColor(){
coordinatorLayout.setBackgroundColor(Color.parseColor(getResources().getString(getColorCodeFromColorIndex(selectedColorIndex))));
bgColorView.setBackgroundColor(Color.parseColor(getResources().getString(getColorCodeFromColorIndex(selectedColorIndex))));
}
private void setLayoutBGImage(){
coordinatorLayout.setBackground(getResources().getDrawable(getImageCodeFromImageIndex(selectedImageIndex)));
}

尝试使用以下模式更改您的代码：
private void setImageResources(int id) {
imageColor1.setImageResource(0);
imageColor2.setImageResource(0);
imageColor3.setImageResource(0);
imageColor4.setImageResource(0);
imageColor5.setImageResource(0);
switch (id) {
default:
case R.id.no_color:
selectedNoteColor = "#FFFFFF";
selectedColorIndex = 0;
coordinatorLayout.setBackgroundColor(getResources().getColor(R.color.DefaultNoteColorDay));
return;
case R.id.color1:
selectedNoteColor = "#FFFFFF";
selectedColorIndex = 0;
imageColor1.setImageResource(R.drawable.ic_done_create);
break;
case R.id.color2:
selectedNoteColor = "#CCF49E";
selectedColorIndex = 1;
imageColor2.setImageResource(R.drawable.ic_done_create);
break;
case R.id.color3:
selectedNoteColor = "#F8A39D";
selectedColorIndex = 2;
imageColor3.setImageResource(R.drawable.ic_done_create);
break;
case R.id.color4:
selectedColorIndex = 3;
selectedNoteColor = "#93CCC6";
imageColor4.setImageResource(R.drawable.ic_done_create);
break;
case R.id.color5:
selectedColorIndex = 4;
selectedNoteColor = "#EFD074";
imageColor5.setImageResource(R.drawable.ic_done_create);
break;
}
setLayoutBGColor();
}
并设置监听器：
View.OnClickListener listener = v-> setImageResource(v.getId());
layoutMisc.findViewById(R.id.no_color).setOnClickListener(listener);
layoutMisc.findViewById(R.id.color1).setOnClickListener(listener);
layoutMisc.findViewById(R.id.color2).setOnClickListener(listener);
layoutMisc.findViewById(R.id.color3).setOnClickListener(listener);
layoutMisc.findViewById(R.id.color4).setOnClickListener(listener);
layoutMisc.findViewById(R.id.color5).setOnClickListener(listener);
