文本转换：大写相当于Android的？

问题描述

这是否存在？我需要一个TextView它总是大写。

Does this exist? I need to make a TextView which is always uppercase.

推荐答案

我没有看到这样的事情在TextView的属性，但是你可能只是使文字大写设置前：

I don't see anything like this in the TextView attributes, however you could just make the text uppercase before setting it:

textView.setText(text.toUpperCase());

如果TextView的是一个EditText和任何你想要的用户类型为大写，你可以实现一个TextWatcher和使用的EditText addTextChangedListener添加它，一个在onTextChange方法取得用户输入并与在同一文本替换大写。

If the TextView is an EditText and you want whatever the user types to be uppercase you could implement a TextWatcher and use the EditText addTextChangedListener to add it, an on the onTextChange method take the user input and replace it with the same text in uppercase.

editText.addTextChangedListener(upperCaseTextWatcher);

final TextWatcher upperCaseTextWatcher = new TextWatcher() {

public void beforeTextChanged(CharSequence charSequence, int i, int i1, int i2) {
}

public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
    editText.setText(editText.getText().toString().toUpperCase());
    editText.setSelection(editText.getText().toString().length());
}

public void afterTextChanged(Editable editable) {
}

};
