android自定义dialog

开发中经常会用到dialog，各种各样的，觉得还是写个通用的自定义dialog，以后直接套用，在这里贴上代码，为了方便以后查阅。

先看效果图

EditDialog.java

public class EditDialog extends Dialog {

    public EditDialog(Context context) {
        super(context);
    }

    public EditDialog(Context context, int theme) {
        super(context, theme);
    }

    public static class Builder {
        private Context context;
        private String title;


        public Builder setEditText(String text) {
            editText = text;
            return this;
        }

        public EditText getmEditTextView() {
            return mEditTextView;
        }

        private EditText mEditTextView;
        private String editText;
        private String positiveButtonText;
        private String negativeButtonText;
        private View contentView;
        private DialogInterface.OnClickListener positiveButtonClickListener;
        private DialogInterface.OnClickListener negativeButtonClickListener;

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


        /**
         * 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) {

                    .getText(negativeButtonText);

        }

        public Builder setNegativeButton(String negativeButtonText,
                                         DialogInterface.OnClickListener listener) {
            this.negativeButtonText = negativeButtonText;
            this.negativeButtonClickListener = listener;
            return this;
        }

        public EditDialog create() {

                                }

    </LinearLayout>
</LinearLayout>

最后贴上使用这个dialog的地方

       final EditDialog.Builder builder = new EditDialog.Builder(this);
        builder.setTitle("编辑导语");
        builder.setEditText("helloword");
        builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialogInterface, int i) {
                dialogInterface.dismiss();
                String edit = builder.getmEditTextView().getText().toString();
                Log.i("shenlong","edit="+edit);
            }
        });

        builder.setNegativeButton("No", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialogInterface, int i) {
                dialogInterface.dismiss();
            }
        });


        builder.create().show();

如果自己实现出来效果不好，应该是有些东西没有设置好，这里是源码地址。
