前言:在做项目的时候,发现dialog界面太丑陋,从csdn上下载了一份自定义dialog的源码,在他的基础上对界面进行美化...有需要的朋友可以直接拿走
效果图如下：
主要代码:
/**
* 自定义dialog
* @author ansen
*/
public class CustomDialog extends Dialog {
public CustomDialog(Context context) {
super(context);
} public CustomDialog(Context context, int theme) {
super(context, theme);
} public static class Builder {
private Context context;
private String title;
private String message;
private String positiveButtonText;
private String negativeButtonText;
private View contentView;
private DialogInterface.OnClickListener positiveButtonClickListener;
private DialogInterface.OnClickListener negativeButtonClickListener; public Builder(Context context) {
this.context = context;
} public Builder setMessage(String message) {
this.message = message;
return this;
} /**
* Set the Dialog message from resource
* @param title
* @return
*/
public Builder setMessage(int message) {
this.message = (String) context.getText(message);
return this;
} /**
* Set the Dialog title from resource
* @param title
* @return
*/
public Builder setTitle(int title) {
this.title = (String) context.getText(title);
return this;
} /**
* Set the Dialog title from String
* @param title
* @return
*/ public Builder setTitle(String title) {
this.title = title;
return this;
} public Builder setContentView(View v) {
this.contentView = v;
return this;
} /**
* Set the positive button resource and it's listener
* @param positiveButtonText
* @return
*/
public Builder setPositiveButton(int positiveButtonText,
DialogInterface.OnClickListener listener) {
this.positiveButtonText = (String) context
.getText(positiveButtonText);
this.positiveButtonClickListener = listener;
return this;
} public Builder setPositiveButton(String positiveButtonText,
DialogInterface.OnClickListener listener) {
this.positiveButtonText = positiveButtonText;
this.positiveButtonClickListener = listener;
return this;
} public Builder setNegativeButton(int negativeButtonText,
DialogInterface.OnClickListener listener) {
this.negativeButtonText = (String) context
.getText(negativeButtonText);
this.negativeButtonClickListener = listener;
return this;
} public Builder setNegativeButton(String negativeButtonText,
DialogInterface.OnClickListener listener) {
this.negativeButtonText = negativeButtonText;
this.negativeButtonClickListener = listener;
return this;
} //创建dialog对象 主要就是这个方法,加载自定义布局文件
public CustomDialog create() {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
// instantiate the dialog with the custom Theme
final CustomDialog dialog = new CustomDialog(context,
R.style.Dialog);
View layout = inflater.inflate(R.layout.dialog_normal_layout, null);
dialog.addContentView(layout, new LayoutParams(
LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
// set the dialog title
((TextView) layout.findViewById(R.id.title)).setText(title);
// set the confirm button
if (positiveButtonText != null) {
((Button) layout.findViewById(R.id.positiveButton))
.setText(positiveButtonText);
if (positiveButtonClickListener != null) {
((Button) layout.findViewById(R.id.positiveButton))
.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
positiveButtonClickListener.onClick(dialog,
DialogInterface.BUTTON_POSITIVE);
}
});
}
} else {
// if no confirm button just set the visibility to GONE
layout.findViewById(R.id.positiveButton).setVisibility(
View.GONE);
}
// set the cancel button
if (negativeButtonText != null) {
((Button) layout.findViewById(R.id.negativeButton))
.setText(negativeButtonText);
if (negativeButtonClickListener != null) {
((Button) layout.findViewById(R.id.negativeButton))
.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
negativeButtonClickListener.onClick(dialog,
DialogInterface.BUTTON_NEGATIVE);
}
});
}
} else {
// if no confirm button just set the visibility to GONE
layout.findViewById(R.id.negativeButton).setVisibility(
View.GONE);
}
// set the content message
if (message != null) {
((TextView) layout.findViewById(R.id.message)).setText(message);
} else if (contentView != null) {
((LinearLayout) layout.findViewById(R.id.content))
.removeAllViews();
((LinearLayout) layout.findViewById(R.id.content)).addView(
contentView, new LayoutParams(LayoutParams.FILL_PARENT,
LayoutParams.FILL_PARENT));
}
dialog.setContentView(layout);
return dialog;
} }
}
4.Activity中如何调用:
CustomDialog.Builder builder = new CustomDialog.Builder(this);
builder.setMessage("这个就是自定义的提示框");
builder.setTitle("提示");
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
//设置你的操作事项
}
}); builder.setNegativeButton("取消",
new android.content.DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
}); builder.create().show();
