自定义dialog

android的Alertdialog的7种形式http://www.oschina.net/question/54100_32486

根据今天的需求查阅资料写了自定义的dialog

几个步骤：

1、继承

2、添加构造

3、写静态类Builder（1.内部类拥有其外围类的所有元素的访问权。2.外部类必须指明内部类的对象类型，利用内部类对象访问内部类成员）

4、内部类主要实现自己需要用的方法，基本有settitle，setmessage，setpositivebuttontext，setpositivebuttonclick，setnegativebuttonclick，setnegativebuttonclick（这些只是名字，不喜欢可以取别的名字，在调用时对应即可）

先上张效果图



demo：

public class BaseDialog extends Dialog{

public BaseDialog(Context context, int theme) {
super(context, theme);
// TODO Auto-generated constructor stub
}
public BaseDialog(Context context) {
super(context);
// TODO Auto-generated constructor stub
}

public static class Builder{
private String title;
private Context context;
private String message;
private String positiveButtonText;
private String negativeButtonText;
private View contentview;
private Boolean cancle;
private DialogInterface.OnClickListener positiveButtonClickListener;
private DialogInterface.OnClickListener negativeButtonClickListener;

public Builder(Context context){
this.context=context;
}

public Builder setMessage(int message) {
this.message = (String) context.getText(message);
return this;
}
public Builder setMessage(String message){
this.message=message;
return this;
}

public Builder setTitle(int title) {
this.title = (String) context.getText(title);
return this;
}
public Builder setTitle(String title) {
this.title = title;
return this;
}

public Builder setContentView(View v) {
this.contentview = v;
return this;
}

public Builder setCancelable(Boolean cancle){
this.cancle=cancle;
return this;
}

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;
}<pre name="code" class="java">	public BaseDialog create(){

下面就是在activity中进行调用，就和调用Alertdialog是一样的。

BaseDialog.Builder builder = new BaseDialog.Builder(this);
builder.setMessage("自定义");
builder.setTitle("我是提示框");
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();

}
});

builder.setNegativeButton("取消",
new android.content.DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});

builder.create().show();
