Question

我想点击一个edittext并显示对话日期，所以我试试

mDateDisplay = (EditText) findViewById(R.id.dateDisplay);
    mDateDisplay.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (hasFocus) {
                showDialog(DATE_DIALOG_ID);
            }
        }
    });

对话框将显示mDateDisplay是否为按钮

但我想使用edittext

我该怎么办？

Answer 1

您可以使用OnClickListener事件来处理对话框，但是在xml文件中禁用EditText的android:focusableInTouchMode后就像这样。例如 - android:focusableInTouchMode="false"。

因为首次触摸EditText时会调用焦点事件，第二次触摸时会调用click事件，因此您必须先禁用焦点事件。

Answer 2

使用此：

mDateDisplay.setClickable(true);
mDateDisplay.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        showDialog(DATE_DIALOG_ID);
    }
});

或者，您可以使用XML中的android:onClick属性指向Activity子类中的单击处理函数。

（当然，当然，当几乎每个人都使用兼容性库时，你可能想要创建并显示一个对话框片段，而不是调用showDialog()，但这个想法是一样的。）

Answer 3

对于我用过的相同的事情：

 sel_date.setClickable(true);
 sel_date.setOnClickListener(new OnClickListener(){
        @Override
        public void onClick(View arg0) {
            // TODO Auto-generated method stub
            showDialog(DEFAULTDATESELECTOR_ID);
        }
    });

并将选定日期设置为EditText的值：

private DateSlider.OnDateSetListener mDateSetListener =
        new DateSlider.OnDateSetListener() {
            public void onDateSet(DateSlider view, Calendar selectedDate) {
                // update the dateText view with the corresponding date
                sel_date.setText(String.format("%te-%tB-%tY", selectedDate, selectedDate, selectedDate).trim());
            }
    };

我已经在Android中编辑了自定义日期选择器中的代码：http://blog.codeus.net/dateslider-1-0-an-alternative-datepicker-for-android/

您可以使用EditText替换Button，并执行与上述代码相同的操作。

当EditText获得焦点时，键盘似乎会弹出。要防止这种情况，请将focusable设置为false：

<EditText
    ...
    android:focusable="false"
    ... />

检查以下代码：

public class Main extends Activity {
EditText et1,et2;
static final int DATE_DIALOG_ID = 0;
static final int DATE_DIALOG_ID1 = 1;
private int mYear;
private int mMonth;
private int mDay;

private int mYear1;
private int mMonth1;
private int mDay1;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    et1=(EditText)findViewById(R.id.EditText01);
    et2=(EditText)findViewById(R.id.EditText02);

    final Calendar c = Calendar.getInstance();
    mYear = c.get(Calendar.YEAR);
    mMonth = c.get(Calendar.MONTH);
    mDay = c.get(Calendar.DAY_OF_MONTH);
    et1.setText("month/year");
    et2.setText("month/year");
    et1.setOnTouchListener(new OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            // TODO Auto-generated method stub
            showDialog(DATE_DIALOG_ID);
            return false;
        }
    });

    et2.setOnTouchListener(new OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            // TODO Auto-generated method stub
            showDialog(DATE_DIALOG_ID1);
            return false;
        }
    });

}

@Override
protected Dialog onCreateDialog(int id) {
    switch (id) {
    case DATE_DIALOG_ID:
        return new DatePickerDialog(this, mDateSetListener, mYear, mMonth,
                mDay);

    case DATE_DIALOG_ID1:
        return new DatePickerDialog(this, mDateSetListener1, mYear1, mMonth1,
                mDay1);
    }
    return null;
}

// updates the date in the TextView

private void updateDisplay() {
    et1.setText(new StringBuilder()
    // Month is 0 based so add 1
            .append(mMonth + 1).append("-").append(mYear));
}
private void updateDisplay1() {

    et2.setText(new StringBuilder()
    // Month is 0 based so add 1
            .append(mMonth1 + 1).append("-").append(mYear1));
}
// the callback received when the user "sets" the date in the dialog
private DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() {
    @Override
    public void onDateSet(DatePicker view, int year, int monthOfYear,
            int dayOfMonth) {
        // TODO Auto-generated method stub
        mYear = year;
        mMonth = monthOfYear;
        mDay = dayOfMonth;
        updateDisplay();
    }
};

private DatePickerDialog.OnDateSetListener mDateSetListener1 = new DatePickerDialog.OnDateSetListener() {
    @Override
    public void onDateSet(DatePicker view, int year1, int monthOfYear1,
            int dayOfMonth1) {
        // TODO Auto-generated method stub
        mYear1 = year1;
        mMonth1 = monthOfYear1;
        mDay1 = dayOfMonth1;
        updateDisplay1();
    }
};

}

Answer 4

我遇到了类似的问题。简单来说，为了解决这个问题，我使用了以下代码：

var express = require('express');
var app = express();

app.all('*', function(req, res){
  res.sendfile("index.html");
});

在XML中：

editText.setClickable(true);
editText.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {
        // showDialog
    }
});

因此，用户无法编辑EditText，只需单击它即可。

Answer 5

这是一个完美的代码，可以为您提供所需的输出：

public class TextView_Calendar extends Activity {
EditText et1,et2;
static final int DATE_DIALOG_ID = 0;

private int mYear;
private int mMonth;
private int mDay;

/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    et1=(EditText)findViewById(R.id.et1);

    final Calendar c = Calendar.getInstance();
    mYear = c.get(Calendar.YEAR);
    mMonth = c.get(Calendar.MONTH);
    mDay = c.get(Calendar.DAY_OF_MONTH);
    et1.setText("month/year");
    et1.setOnTouchListener(new OnTouchListener()
    {
        public boolean onTouch(View v, MotionEvent event)
        {
            showDialog(DATE_DIALOG_ID);
            return false;
        }
    });

}

@Override
protected Dialog onCreateDialog(int id) {
    switch (id) {
    case DATE_DIALOG_ID:
        return new DatePickerDialog(this, mDateSetListener, mYear, mMonth, mDay);
    }
    return null;
}

// updates the date in the TextView

private void updateDisplay() {
    et1.setText(new StringBuilder()
    // Month is 0 based so add 1
            .append(mDay).append("-").append(mMonth + 1).append("-").append(mYear));
}

// the callback received when the user "sets" the date in the dialog
private DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() {
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
        mYear = year;
        mMonth = monthOfYear;
        mDay = dayOfMonth;
        updateDisplay();
    }
};

}

Answer 6

我用以下onFocusChangeListener方式做到了：

mCompleteByEditText = (EditText) findViewById(R.id.completion);
        mCompleteByEditText
                .setOnFocusChangeListener(new OnFocusChangeListener() {

                    @Override
                    public void onFocusChange(View v, boolean hasFocus) {
                        if (hasFocus) {
                            DialogFragment newFragment = new TimePickerFragment();
                            newFragment.show(getSupportFragmentManager(),
                                    "timePicker");
                        }
                    }
                });

hasFocus变量控制当前EditText是否具有焦点。

是否有可能在单击edittext时显示对话框消息？
