先定义个一个继承自Dialog的自定义弹框CustomDialog
import android.app.Dialog;import android.content.Context;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.Button;import android.widget.TextView; public class CustomDialog extends Dialog { private CustomDialog(Context context) { super(context); } private CustomDialog(Context context, int themeResId) { super(context, themeResId); } private CustomDialog(Context context, boolean cancelable, OnCancelListener cancelListener) { super(context, cancelable, cancelListener); } public static class Builder { private TextView tvTitle, tvWarning, tvInfo; private Button btnCancel, btnConfirm; private View mLayout; private View.OnClickListener mButtonCancelClickListener; private View.OnClickListener mButtonConfirmClickListener; private CustomDialog mDialog; public Builder(Context context) { mDialog = new CustomDialog(context, R.style.custom_dialog); LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); // 加载布局文件 mLayout = inflater.inflate(R.layout.dialog_custom, null, false); // 添加布局文件到 Dialog mDialog.addContentView(mLayout, new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT)); tvTitle = (TextView) mLayout.findViewById(R.id.tv_title); tvWarning = (TextView) mLayout.findViewById(R.id.tv_warning); tvInfo = (TextView) mLayout.findViewById(R.id.tv_info); btnCancel = (Button) mLayout.findViewById(R.id.btn_cancel); btnConfirm = (Button) mLayout.findViewById(R.id.btn_confirm); } public Builder setTitle(String title) { tvTitle.setText(title); tvTitle.setVisibility(View.VISIBLE); return this; } public Builder setWarning(String waring) { tvWarning.setText(waring); if (waring == null || waring.equals("")) { tvWarning.setVisibility(View.GONE); } return this; } public Builder setInfo(String message) { tvInfo.setText(message); return this; } public Builder setButtonCancel(String text, View.OnClickListener listener) { btnCancel.setText(text); mButtonCancelClickListener = listener; return this; } public Builder setButtonConfirm(String text, View.OnClickListener listener) { btnConfirm.setText(text); mButtonConfirmClickListener = listener; return this; } public CustomDialog create() { btnCancel.setOnClickListener(new android.view.View.OnClickListener() { @Override public void onClick(View view) { mDialog.dismiss(); mButtonCancelClickListener.onClick(view); } }); btnConfirm.setOnClickListener(new android.view.View.OnClickListener() { @Override public void onClick(View view) { mDialog.dismiss(); mButtonConfirmClickListener.onClick(view); } }); mDialog.setContentView(mLayout); mDialog.setCancelable(true); mDialog.setCanceledOnTouchOutside(false); return mDialog; } }}定义CustomDialo布局文件：dialog_custom
