javascript - EditText Values Get Written To Database Values On Cancel

问题描述

I have a dialog box that allowing the user to enter in values, each value gets validated to ensure the correct value has been entered. However on an invalid entry the values of the EditText are getting written to the SQLite database when the user clicks Cancel.

This is my code for the Dialog Box:

final AlertDialog alertDialog = alertDialogBuilderUserInput.create();
        alertDialog.show();

        alertDialog.getButton( AlertDialog.BUTTON_POSITIVE).setOnClickListener( new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //Show Toast Message When No Text Is Entered
                //Validation Being Done Here
                if (TextUtils.isEmpty(inputScore.getText().toString())) {
                    inputScore.setText( "0" );
                    //return;
                }
                if (TextUtils.isEmpty(inputStrikes.getText().toString())) {
                    inputStrikes.setText( "0" );
                    //return;
                }
                if (TextUtils.isEmpty(inputSpares.getText().toString())) {
                    inputSpares.setText( "0" );
                    //return;
                }
                if (TextUtils.isEmpty(inputSplits.getText().toString())) {
                    inputSplits.setText( "0" );
                    //return;
                }
                if (TextUtils.isEmpty(inputSplitConversions.getText().toString())) {
                    inputSplitConversions.setText( "0" );
                    //return;
                }
                if (TextUtils.isEmpty(inputOpenFrames.getText().toString())) {
                    inputOpenFrames.setText( "0" );
                    //return;
                }

                final int valueScore = Integer.valueOf(inputScore.getText().toString());
                final int valueStrikes = Integer.valueOf(inputStrikes.getText().toString());
                final int valueSpares = Integer.valueOf(inputSpares.getText().toString());
                final int valueSplits = Integer.valueOf(inputSplits.getText().toString());
                final int valueSplitConversions = Integer.valueOf(inputSplitConversions.getText().toString());
                final int valueOpenFrame = Integer.valueOf(inputOpenFrames.getText().toString());
                if (valueScore > 300) {
                    inputScore.setError("Maximum value allowed is 300");
                    //return;
                } else
                if (valueStrikes > 12) {
                    inputStrikes.setError("Maximum value allowed is 12");
                    //return;
                } else
                if (valueSpares > 10) {
                    inputSpares.setError("Maximum value allowed is 10");
                    //return;
                } else
                if (valueSplits > 10) {
                    inputSplits.setError("Maximum value allowed is 10");
                    //return;
                } else
                if (valueSplitConversions > 10) {
                    inputSplitConversions.setError("Maximum value allowed is 10");
                    //return;
                } else
                if (valueOpenFrame > 10) {
                    inputOpenFrames.setError("Maximum value allowed is 10");
                    //return;
                } else {

                        alertDialog.dismiss();
                    }


                //Check If User Is Updating Game
                //Create New Game
                if (shouldUpdate && game != null) {
                    //Update Game By It's Id
                    updateGame(inputScore.getText().toString(), inputStrikes.getText().toString(), inputSpares.getText().toString(), inputSplits.getText().toString(), inputSplitConversions.getText().toString(), inputOpenFrames.getText().toString(), position);
                } else {
                    createGame(leagueId.getText().toString(), bowlerId.getText().toString(), seriesId.getText().toString(), inputScore.getText().toString(), inputStrikes.getText().toString(), inputSpares.getText().toString(), inputSplits.getText().toString(), inputSplitConversions.getText().toString(), inputOpenFrames.getText().toString());
                }
                seriesAverage = db.getSeriesAverage(savedLeagueId, savedBowlerId, savedSeriesId);
                bowlerAverage = db.getBowlerAverage(savedLeagueId, savedBowlerId);
                leagueAverage = db.getLeagueAverage(savedLeagueId);
            }
        });

    }

I would like it to display all the fields that are incorrect at once and not save the values on a cancel. Can't seem to get this to happen though. Below is a image of what is currently happening.

解决方案

试试这个代码，它带有一个布尔标志，指示所有值是否都有效。
我包含取消按钮的代码只是为了关闭对话框（我希望没有拼写错误）。

final AlertDialog alertDialog = alertDialogBuilderUserInput.create();
alertDialog.show();

alertDialog.getButton(AlertDialog.BUTTON_POSITIVE).setOnClickListener( new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        //Show Toast Message When No Text Is Entered
        //Validation Being Done Here
        Boolean allValid = true;

        if (TextUtils.isEmpty(inputScore.getText().toString())) {
            allValid = false;
            inputScore.setText( "0" );
        }
        if (TextUtils.isEmpty(inputStrikes.getText().toString())) {
            allValid = false;
            inputStrikes.setText( "0" );
        }
        if (TextUtils.isEmpty(inputSpares.getText().toString())) {
            allValid = false;
            inputSpares.setText( "0" );
        }
        if (TextUtils.isEmpty(inputSplits.getText().toString())) {
            allValid = false;
            inputSplits.setText( "0" );
        }
        if (TextUtils.isEmpty(inputSplitConversions.getText().toString())) {
            allValid = false;
            inputSplitConversions.setText( "0" );
        }
        if (TextUtils.isEmpty(inputOpenFrames.getText().toString())) {
            allValid = false;
            inputOpenFrames.setText( "0" );
        }

        final int valueScore = Integer.valueOf(inputScore.getText().toString());
        final int valueStrikes = Integer.valueOf(inputStrikes.getText().toString());
        final int valueSpares = Integer.valueOf(inputSpares.getText().toString());
        final int valueSplits = Integer.valueOf(inputSplits.getText().toString());
        final int valueSplitConversions = Integer.valueOf(inputSplitConversions.getText().toString());
        final int valueOpenFrame = Integer.valueOf(inputOpenFrames.getText().toString());
        if (valueScore > 300) {
            allValid = false;
            inputScore.setError("Maximum value allowed is 300");
        } 
        if (valueStrikes > 12) {
            allValid = false;
            inputStrikes.setError("Maximum value allowed is 12");
        } 
        if (valueSpares > 10) {
            allValid = false;
            inputSpares.setError("Maximum value allowed is 10");
        } 
        if (valueSplits > 10) {
            allValid = false;
            inputSplits.setError("Maximum value allowed is 10");
        } 
        if (valueSplitConversions > 10) {
            allValid = false;
            inputSplitConversions.setError("Maximum value allowed is 10");
        } 
        if (valueOpenFrame > 10) {
            allValid = false;
            inputOpenFrames.setError("Maximum value allowed is 10");
        } 

        if (!allValid) {
            return;
        }

        alertDialog.dismiss();

        //Check If User Is Updating Game
        //Create New Game
        if (shouldUpdate && game != null) {
            //Update Game By It's Id
            updateGame(inputScore.getText().toString(), inputStrikes.getText().toString(), inputSpares.getText().toString(), inputSplits.getText().toString(), inputSplitConversions.getText().toString(), inputOpenFrames.getText().toString(), position);
        } else {
            createGame(leagueId.getText().toString(), bowlerId.getText().toString(), seriesId.getText().toString(), inputScore.getText().toString(), inputStrikes.getText().toString(), inputSpares.getText().toString(), inputSplits.getText().toString(), inputSplitConversions.getText().toString(), inputOpenFrames.getText().toString());
        }
        seriesAverage = db.getSeriesAverage(savedLeagueId, savedBowlerId, savedSeriesId);
        bowlerAverage = db.getBowlerAverage(savedLeagueId, savedBowlerId);
        leagueAverage = db.getLeagueAverage(savedLeagueId);
    }
});

alertDialog.getButton( AlertDialog.BUTTON_NEGATIVE).setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        alertDialog.dismiss();
    }
});
