你也可以像这样把光标放在EditText视图中文本的末尾:

EditText et = (EditText)findViewById(R.id.textview);
int textLength = et.getText().length();
et.setSelection(textLength, textLength);

我测试过的所有其他代码都没有很好地工作，因为用户仍然可以将插入符号/光标放在字符串中间的任何地方(例如:12|3.00 -其中|是光标)。我的解决方案总是在EditText上发生触摸时将光标放在字符串的末尾。

最终的解决方案是:

// For a EditText like:
<EditText
    android:id="@+id/EditTextAmount"
    android:layout_height="wrap_content"
    android:layout_width="fill_parent"
    android:hint="@string/amount"
    android:layout_weight="1"
    android:text="@string/zero_value"
    android:inputType="text|numberDecimal"
    android:maxLength="13" />

字符串值:

@string/amount="0.00"
@string/zero_value="0.00"

在代码:

// Create a Static boolean flag
private static boolean returnNext; 


// Set caret/cursor to the end on focus change
EditTextAmount.setOnFocusChangeListener(new View.OnFocusChangeListener() {
    @Override
    public void onFocusChange(View editText, boolean hasFocus) {
        if(hasFocus) {
            ((EditText) editText).setSelection(((EditText) editText).getText().length());
        }
    }
});

// Create a touch listener and put caret to the end (no matter where the user touched in the middle of the string)
EditTextAmount.setOnTouchListener(new View.OnTouchListener() {
    @Override
    public boolean onTouch(View editText, MotionEvent event) {
        ((EditText) editText).onTouchEvent(event);
        ((EditText) editText).setSelection(((EditText) editText).getText().length());
        return true;
    }
});


// Implement a Currency Mask with addTextChangedListener
EditTextAmount.addTextChangedListener(new TextWatcher() {
    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
        String input = s.toString();
        String output = new String();
        String buffer = new String();
        String decimals = new String();
        String numbers = Integer.toString(Integer.parseInt(input.replaceAll("[^0-9]", "")));

        if(returnNext) {
            returnNext = false;
            return;
        }

        returnNext = true;

        if (numbers.equals("0")) {
            output += "0.00";
        } else if (numbers.length() <= 2) {
            output += "0." + String.format("%02d", Integer.parseInt(numbers));
        } else if(numbers.length() >= 3) {
            decimals = numbers.substring(numbers.length() - 2);
            int commaCounter = 0;
            for(int i = numbers.length() - 3; i >= 0; i--) {
                if(commaCounter == 3) {
                    buffer += ",";
                    commaCounter = 0;
                }
                buffer += numbers.charAt(i);
                commaCounter++;
            }
            output = new StringBuilder(buffer).reverse().toString() + "." + decimals;
        }

        EditTextAmount.setText(output);
        EditTextAmount.setSelection(EditTextAmount.getText().length());
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
        /*String input = s.toString();
        if(input.equals("0.0")) {
            EditTextAmount.setText("0.00");
            EditTextAmount.setSelection(EditTextAmount.getText().length());
            return;
        }*/
    }

    @Override
    public void afterTextChanged(Editable s) {

    }
});

希望能有所帮助!

你也可以像这样把光标放在EditText视图中文本的末尾:

EditText et = (EditText)findViewById(R.id.textview);
int textLength = et.getText().length();
et.setSelection(textLength, textLength);

这是另一种可能的解决方案:

et.append("");

如果因为某种原因不管用，试试下面的方法:

et.setSelection(et.getText().length());

如果你想选择所有文本，只是输入新的文本而不是旧的，你可以使用

    android:selectAllOnFocus="true"

这是

Editable etext = edittext.getText();
Selection.setSelection(etext,edittext.getText().toString().length());
