2、多选项dialog

private String[] favor = {"美容  ", "汽车  ", "游戏  ", "社交  ", "体育  ", "阅读  ","影视  ", "母婴  ", "健康  ", "家居  ", "服饰  ", "其他  "};
private String hobby;
private int befoid;

    //兴趣爱好设置private void hobbySetting() {AlertDialog.Builder dialogm = new AlertDialog.Builder(this);dialogm.setMultiChoiceItems(favor, new boolean[]{false, false, false, false, false, false, false, false, false, false, false, false},new DialogInterface.OnMultiChoiceClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which, boolean isChecked) {if (!TextUtils.isEmpty(hobby)&&hobby.split("\\  ").length > 2&&befoid!=which) {

默认提示框

public class DialogUtils {//自定义View对话框public static Dialog show(Context context, View view) {AlertDialog.Builder builder = new AlertDialog.Builder(context).setView(view).setCancelable(true);Dialog dialog = builder.show();dialog.getWindow().getDecorView().setBackground(null);return dialog;}}

调用

//软件说明对话框
public void showDescription() {View view = LayoutInflater.from(mContext).inflate(R.layout.dialog_description, null);//软件说明Button btnDismiss = view.findViewById(R.id.btn_dismiss);mTxvModeChoose = view.findViewById(R.id.txv_mode_choose);final Dialog dialog = DialogUtils.show(mContext, view);btnDismiss.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {//点击右上角 × 关闭弹窗dialog.dismiss();}});mTxvModeChoose.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {//点击选择模式mTxvModeChoose.setBackgroundResource(R.drawable.txv_stroke);mTxvModeFill.setBackground(null);mTxvDictionary.setBackground(null);mTxvDescription.setText(R.string.str_descrip_choose);}});}

 点击事件Dialog

public class TipDialog2 extends Dialog {@BindView(R.id.Cancel_tv)TextView mCancelTv;@BindView(R.id.confirm_tv)TextView mConfirmTv;@BindView(R.id.tv_content)TextView mTvContent;@BindView(R.id.tv_title)TextView mTvTitle;private CallBack mCallBack;public TipDialog2(@NonNull Context context) {super(context, R.style.CommonDialogStyle);setContentView(R.layout.dialog_tip2);ButterKnife.bind(this);}@OnClick({ R.id.Cancel_tv, R.id.confirm_tv })public void onClick(View view) {switch (view.getId()) {case R.id.Cancel_tv:dismiss();break;case R.id.confirm_tv:if (mCallBack != null) {mCallBack.confirm();}dismiss();break;}}public void setCallBack(CallBack callBack) {this.mCallBack = callBack;}public interface CallBack {void confirm();}public void setTitle(boolean isVisible,String title){mTvTitle.setVisibility(isVisible?View.VISIBLE:View.GONE);mTvTitle.setText(title);}public void setTvContent(String content) {mTvContent.setText(content);}
}

调用

TipDialog2 tipDialog2 = new TipDialog2(this);
tipDialog2.setCallBack(new TipDialog2.CallBack() {@Overridepublic void confirm() {finish();}
});
tipDialog2.show();

EditText键盘不弹出 

//弹出软键盘
public void showKeyboard(EditText editText) {//其中editText为dialog中的输入框的 EditTextif(editText!=null){//设置可获得焦点editText.setFocusable(true);editText.setFocusableInTouchMode(true);//请求获得焦点editText.requestFocus();//调用系统输入法InputMethodManager inputManager = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);inputManager.showSoftInput(editText, 0);}
