Android自定义弹框样式

弹框样式的自定义是通过改变v7包下的alertDialog的Window对象的view及控制Window的宽高实现的。所有源码如下，其中自定义View的宽度设置为手机屏幕宽度的82%。 

import android.app.Dialog;
import android.content.Context;
import android.support.v7.app.alertDialog;
import android.text.TextUtils;
import android.view.LayoutInflater;
import android.view.View;
import android.view.Window;
import android.view.WindowManager;

public class CustomDialog {
 private Context mContext;
 private String mTitle;
 private String mMessage;

 private boolean mCancelable=true;
 private boolean mShowoneBtn=false;//只显示一个按钮

 }
 
 
 public void show() {
 mDialog=showCustomSimpleDialog(mContext, mTitle, mMessage,mCustomView, mPositiveText,mPositiveListener,mNegativeText,mNegativeListener,mCancelable,mShowOneBtn);
 }
 
 public void cancel(){
 if (mDialog!=null){
 mDialog.cancel();
 }
 }
 
 public static class Builder {

 customDialog.mCancelable=this.mCancelable;
 customDialog.mShowoneBtn=this.mShowOneBtn;
 customDialog.mCustomView=this.mCustomView;
 customDialog.show();
 return customDialog;
 }
 }
 
 public interface onPositiveButtonClickListener {
 void onPositiveButtonClick(Dialog dialog);
 }

 }
 
 public static Dialog showCustomSimpleDialog(Context context, String title, String msg,View customView,
   String positiveText,onPositiveButtonClickListener positiveListener,

   boolean cancelable, boolean showOneBtn) {
 alertDialog.Builder builder = new alertDialog.Builder(context);
 Dialog dialog = builder.show();
 //是否可以取消
 dialog.setCancelable(cancelable);
 Window window = dialog.getWindow();
 
 View view = LayoutInflater.from(context).inflate(R.layout.dialog_simple_toast, null);
 
 TextView clickNegative = view.findViewById(R.id.click_negative);

 if (customView!=null){
 dialogMsg.setVisibility(View.GONE);
 dialogCustomViewContainer.setVisibility(View.VISIBLE);
 dialogCustomViewContainer.addView(customView);
 }else {
 dialogMsg.setVisibility(View.VISIBLE);
 //消息自定义
 if (!TextUtils.isEmpty(msg)) {
 dialogMsg.setText(msg);

 //确认按钮自定义
 if (!TextUtils.isEmpty(positiveText)) {

 if (!TextUtils.isEmpty(negativeText)){

 //取消
 clickNegative.setonClickListener(new View.onClickListener() {

  positiveListener.onPositiveButtonClick(dialog);
 }
 }
 });
 
 if (window != null) {
 WindowManager.LayoutParams params = window.getAttributes();
 params.width = CommonUtil.getPhoneWidth(context) * 82 / 100;
 window.setAttributes(params);
 window.setBackgroundDrawableResource(R.drawable.bg_white_corner_5);
 window.setContentView(view);
 }
 return dialog;
 }
}

使用方式如下：链式调用，可查看源码自己选择使用。

CustomDialog.Builder builder=new CustomDialog.Builder(mContext);
 builder.setTitle("自定义弹框")//默认为“提示”
  .setMessage("自定义内容")
  .setNegativeText("自定义取消文字")//默认为“取消”
  .setPositiveText("自定义确认文字")//默认为 “确认”
  .setonPositiveButtonClickListener(new CustomDialog.onPositiveButtonClickListener() {
  @Override
  public void onPositiveButtonClick(Dialog dialog) {
  ToastUtil.makeText(mContext,"自定义确认按钮监听逻辑处理");
  }
  })
  .setonNegativeButtonClickListener(new CustomDialog.onNegativeButtonClickListener() {
  @Override
  public void onNegativeButtonClick(Dialog dialog) {
  ToastUtil.makeText(mContext,"自定义取消按钮监听逻辑处理");
  }
  })
  .setCancelable(false)//默认true
  .build();

效果图如下，使用者可按照实际需要自定义xml文件进行更改：
