我在用阿拉伯语工作和活动。我希望用户名和密码的提示从右边开始,从左边开始输入没有问题,但是在我的ui中,我希望提示是右边的。但是当我为edittext添加inputtype时,提示移到左边,我试图用编程的方法解决它,但是没有成功。

    EditText password = (EditText) findViewById(R.id.input_password);
    password.setTypeface(Typeface.DEFAULT);

XML
<EditText
            android:id="@+id/input_password"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:hint="كلمة المرور"
            android:textColorHint="#FFFFFF"
            android:inputType="textPassword"
            android:background="@null"
            android:textColor="#FFFFFF"
            android:textSize="20dp"/>

最佳答案

这是android框架中的一个bug,用于android 4.4+中的edittext字段:https://issuetracker.google.com/issues/37082815https://code.google.com/p/android/issues/detail?id=201471。截至2016年7月,该案件目前尚未解决。
不过,有一种解决方法:
要使提示正确显示在右侧(在从右到左/rtl模式下),必须在没有输入文本时删除inputType属性textPasswordInputType.TYPE_TEXT_VARIATION_PASSWORD)。
要保留显示点以隐藏键入文本的密码输入字段行为,必须在输入第一个字符时动态启用InputType.TYPE_TEXT_VARIATION_PASSWORD。并且必须在删除所有字符时重置。
为了防止拉丁字符输入(ltr文本,如“abc123”)的ui故障跳到左边或完全消失,必须显式地将textdirection设置为rtl。
详情如下:
您的AndroidManifest.xml的先决条件:

<application
    ...
    android:supportsRtl="true"
    ... >
</application>

XML布局包含:
     <EditText
        android:id="@+id/password"
        android:inputType="textPassword"
        android:hint="סיסמא"
        ... />

具有解决方案错误修复的Java代码:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.login_fragment_layout, container, false);
    final EditText password = (EditText) view.findViewById(R.id.password);

    // Workaround https://issuetracker.google.com/issues/37082815 for Android 4.4+
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT && isRTL(getActivity())) {

        // Force a right-aligned text entry, otherwise latin character input,
        // like "abc123", will jump to the left and may even disappear!
        password.setTextDirection(View.TEXT_DIRECTION_RTL);

        // Make the "Enter password" hint display on the right hand side
        password.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);
    }

    password.addTextChangedListener(new TextWatcher() {

        boolean inputTypeChanged;

        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {}

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {}

        @Override
        public void afterTextChanged(Editable s) {

            // Workaround https://code.google.com/p/android/issues/detail?id=201471 for Android 4.4+
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT && isRTL(getActivity())) {
                if (s.length() > 0) {
                    if (!inputTypeChanged) {

                        // When a character is typed, dynamically change the EditText's
                        // InputType to PASSWORD, to show the dots and conceal the typed characters.
                        password.setInputType(InputType.TYPE_CLASS_TEXT |
                                InputType.TYPE_TEXT_VARIATION_PASSWORD |
                                InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);

                        // Move the cursor to the correct place (after the typed character)
                        password.setSelection(s.length());

                        inputTypeChanged = true;
                    }
                } else {
                    // Reset EditText: Make the "Enter password" hint display on the right
                    password.setInputType(InputType.TYPE_CLASS_TEXT |
                            InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);

                    inputTypeChanged = false;
                }
            }
        }
    });

    return view;
}

public static boolean isRTL(Context context) {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
        return context.getResources().getConfiguration().getLayoutDirection()
                == View.LAYOUT_DIRECTION_RTL;
        // Another way:
        // Define a boolean resource as "true" in res/values-ldrtl
        // and "false" in res/values
        // return context.getResources().getBoolean(R.bool.is_right_to_left);
    } else {
        return false;
    }
}
