Question

您好我正在尝试编写一个小应用程序，当系统上的星期日是星期日时，它应该会拉出一个对话框，它正在做得很好。但是，当我将信息放在对话框的框中并单击“提交”时，它仍然显示我已设置的emptyBox的第二个对话框。

所以回顾一下对话框的所有项目都在工作，除了系统仍然看到EditText框为空，但那里有一个值。价值只会是数字。

final Dialog sundayDialog = new Dialog(this);

    sundayDialog.setContentView(R.layout.sunday_dialog);
    Button sundaySubmitBtn = (Button) sundayDialog
            .findViewById(R.id.sundayDialogSubmitBtn);
    Button sundayCancelBtn = (Button) sundayDialog
            .findViewById(R.id.sundayDialogCancelBtn);

    sundaySubmitBtn.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // Submit Button
            setContentView(R.layout.sunday_dialog);
            final EditText etAmountBought = (EditText) findViewById(R.id.amountBoughtET);
            final EditText etCost = (EditText) findViewById(R.id.pricePaidET);
            String amountBought = etAmountBought.getText().toString();
            String cost = etCost.getText().toString();
            if (amountBought.isEmpty() || cost.isEmpty()) {

                //sundayDialog.dismiss();
                emptyETDialogCall();
            } else {
                try {

                    mAmountBought = Integer.parseInt(amountBought);
                    mPricePaid = Integer.parseInt(cost);

                } catch (NullPointerException e) {
                    Log.e(TAG, "Error in sunday dialog in try/catch");
                }
            }
            if (mPricePaid >= 250) {
                costTooHighDialogCall();
                mPricePaid = 0;
            }

            // textBlockDisplay(); // Update the text block with input.
        }

    });

    sundayCancelBtn.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // Cancel Button
            sundayDialog.dismiss();
            sundayCancelDialog();


        }
    });

    sundayDialog.show();
}

这是logcat中唯一显示的内容：

 08-04 11:42:44.780: W/IInputConnectionWrapper(1209): finishComposingText on inactive InputConnection

我不确定这是否是原因，但每次都要重置内容视图。这应仅在onCreate中调用一次，否则只需删除元素并使用inflater添加新元素。我想每次重置内容视图时，它都会重置文本框。

我想，我遇到了你的问题。

<强> sundayDialog.setContentView（R.layout.sunday_dialog）; 这是您为自定义对话框设置的视图。这很好。

再次点击按钮后，您将重置布局这会再次创建所有视图，并且您将重置所有内容。

final Dialog sundayDialog = new Dialog（this）;

sundayDialog.setContentView(R.layout.sunday_dialog);
Button sundaySubmitBtn = (Button) sundayDialog
        .findViewById(R.id.sundayDialogSubmitBtn);
Button sundayCancelBtn = (Button) sundayDialog
        .findViewById(R.id.sundayDialogCancelBtn);

sundaySubmitBtn.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
        // Submit Button

//这里我删除了setContent View ....

        final EditText etAmountBought = (EditText) findViewById(R.id.amountBoughtET);
        final EditText etCost = (EditText) findViewById(R.id.pricePaidET);
        String amountBought = etAmountBought.getText().toString();
        String cost = etCost.getText().toString();
        if (amountBought.isEmpty() || cost.isEmpty()) {

            //sundayDialog.dismiss();
            emptyETDialogCall();
        } else {
            try {

                mAmountBought = Integer.parseInt(amountBought);
                mPricePaid = Integer.parseInt(cost);

            } catch (NullPointerException e) {
                Log.e(TAG, "Error in sunday dialog in try/catch");
            }
        }
        if (mPricePaid >= 250) {
            costTooHighDialogCall();
            mPricePaid = 0;
        }

        // textBlockDisplay(); // Update the text block with input.
    }

});

sundayCancelBtn.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
        // Cancel Button
        sundayDialog.dismiss();
        sundayCancelDialog();


    }
});

sundayDialog.show();

}

对话框不从EditText框中提取信息
