对话与自定义视图背景 [英] Dialog with custom view background
问题描述
解决:请参阅下面的
答案我是子类对话框来创建一个自定义背景的对话框。我添加了一个子类视图对话框,它是正确绘制位图背景和布局。但是,按钮将不会对任何触摸事件。
我怀疑的LinearLayout有对话框类加载,但我想我必须加载它在视图类上绘制位图的顶部。
我是全新的Android开发人员,所以我对这个问题表示歉意。下面是我在做什么:
公共类CustomDialog扩展对话框{私有静态最后弦乐TAG =CustomDialog;
私有静态诠释layoutWidth = 640;
私有静态诠释layoutHeight = 400;公共CustomDialog(上下文的背景下){ 超(背景下,android.R.style.Theme_Translucent_NoTitleBar); requestWindowFeature(Window.FEATURE_NO_TITLE); 的LayoutParams PARAMS = getWindow()的getAttributes()。
params.width = LayoutParams.FILL_PARENT;
getWindow()setAttributes((android.view.WindowManager.LayoutParams)PARAMS)。//的setContentView(R.layout.layout_dialog); //这工作得很好,按键的工作
的setContentView(新NewLayoutDialogView(上下文));
}公共静态类NewLayoutDialogView扩展视图{ 私人可绘制BG;
公众的LinearLayout布局;
私人OnColorChangedListener mListener; 公共接口OnBrushChangedListener {
无效brushChanged(浮点半径);
} NewLayoutDialogView(上下文的背景下){ 超级(上下文); 。InputStream的流= getResources()openRawResource(R.drawable.dialog_bg);
BG = NinePatchDrawable.createFromStream(流,NULL); 布局=(的LinearLayout)LinearLayout.inflate(背景下,R.layout.layout_dialog,NULL); OK按钮=(按钮)layout.findViewById(R.id.ok_button); layout.setWillNotDraw(假); layout.setVisibility(View.VISIBLE);
setVisibility(View.VISIBLE); layout.measure(layoutWidth,layoutHeight);
layout.layout(0,0,layoutWidth,layoutHeight);
} @覆盖
保护无效的onDraw(帆布油画){ 如果(BG!= NULL){
bg.setBounds(10,0,canvas.getWidth(),canvas.getHeight());
bg.draw(画布);
} layout.draw(画布);
}
}
}
编辑:这是我如何设置监听器。我必须禁用此code。使用如图所示的视图子类时。但按键还是应该表现出不,他们没有一个听众点击状态。
对话对话框=新ChangeLayoutDialog(getActivity()); 按钮取消=(按钮)dialog.findViewById(R.id.cancel_button);
cancel.setTypeface(字体);
cancel.setOnClickListener(新View.OnClickListener(){
公共无效的onClick(视图v){
dialog.dismiss();
}
}); OK按钮=(按钮)dialog.findViewById(R.id.ok_button);
ok.setTypeface(字体);
ok.setOnClickListener(新View.OnClickListener(){
公共无效的onClick(视图v){
dialog.dismiss();
setCellLayout(layoutFile);
}
});
,所有我需要做的是补充:
getWindow()setBackgroundDrawableResource(R.drawable.dialog_bg)。
我想我只是想这样太辛苦了!
Solved: see answer below
I am sub-classing Dialog to create a dialog with a custom background. I have added a subclass View to the Dialog and it is drawing the bitmap background and layout correctly. But the buttons will not respond to any touch events.
I suspect the LinearLayout has to be loaded in the Dialog class, but I think I have to load it in the view class to draw on top of the bitmap.
I am totally new to Android dev, so I apologize for the question. Here is what I am doing:
public class CustomDialog extends Dialog {
private static final String TAG = "CustomDialog";
private static int layoutWidth = 640;
private static int layoutHeight = 400;
public CustomDialog(Context context) {
super(context, android.R.style.Theme_Translucent_NoTitleBar);
requestWindowFeature(Window.FEATURE_NO_TITLE);
LayoutParams params = getWindow().getAttributes();
params.width = LayoutParams.FILL_PARENT;
getWindow().setAttributes((android.view.WindowManager.LayoutParams) params);
// setContentView(R.layout.layout_dialog); // This works fine, the buttons work
setContentView(new NewLayoutDialogView(context));
}
public static class NewLayoutDialogView extends View {
private Drawable bg;
public LinearLayout layout;
private OnColorChangedListener mListener;
public interface OnBrushChangedListener {
void brushChanged(float radius);
}
NewLayoutDialogView(Context context) {
super(context);
InputStream stream = getResources().openRawResource(R.drawable.dialog_bg);
bg = NinePatchDrawable.createFromStream(stream, null);
layout = (LinearLayout) LinearLayout.inflate(context, R.layout.layout_dialog, null);
Button ok = (Button) layout.findViewById(R.id.ok_button);
layout.setWillNotDraw(false);
layout.setVisibility(View.VISIBLE);
setVisibility(View.VISIBLE);
layout.measure(layoutWidth, layoutHeight);
layout.layout(0, 0, layoutWidth, layoutHeight);
}
@Override
protected void onDraw(Canvas canvas){
if (bg != null) {
bg.setBounds(10, 0, canvas.getWidth(), canvas.getHeight());
bg.draw(canvas);
}
layout.draw(canvas);
}
}
}
Edit: This is how I am setting the listeners. I have to disable this code when using the View subclass as shown. But the buttons should still show the click state without a listener which they don't.
Dialog dialog = new ChangeLayoutDialog(getActivity());
Button cancel = (Button) dialog.findViewById(R.id.cancel_button);
cancel.setTypeface(font);
cancel.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
dialog.dismiss();
}
});
Button ok = (Button) dialog.findViewById(R.id.ok_button);
ok.setTypeface(font);
ok.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
dialog.dismiss();
setCellLayout(layoutFile);
}
});
Instead of adding the subview class and drawing the background, all I needed to do was add:
getWindow().setBackgroundDrawableResource(R.drawable.dialog_bg);
I guess I was just trying way too hard!
