当EditText处于密码模式时,提示似乎以不同的字体显示(courier ?)我该如何避免这种情况?我想提示出现在相同的字体,当EditText不是在密码模式。
我当前的xml:
<EditText
android:hint="@string/edt_password_hint"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:password="true"
android:singleLine="true" />
我使用这个解决方案来切换字体取决于提示可见性。它与Joe的答案类似,但扩展了EditText:
public class PasswordEditText extends android.support.v7.widget.AppCompatEditText {
public PasswordEditText(Context context) {
super(context);
}
public PasswordEditText(Context context, AttributeSet attrs) {
super(context, attrs);
}
public PasswordEditText(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
@Override
protected void onTextChanged(CharSequence text, int start, int lengthBefore, int lengthAfter) {
super.onTextChanged(text, start, lengthBefore, lengthAfter);
if (text.length() > 0) setTypeface(Typeface.MONOSPACE);
else setTypeface(Typeface.DEFAULT);
}
}
其他答案是大多数情况下的正确解决方案。
但是,如果使用自定义EditText子类,比如在默认情况下应用自定义字体,就会出现一个微妙的问题。如果你在子类的构造函数中设置了自定义字体,如果你设置inputType="textPassword",它仍然会被系统覆盖。
在这种情况下,移动你的样式到onAttachedToWindow后你的超级。onAttachedToWindow电话。
示例实现:
package net.petosky.android.ui;
import android.content.Context;
import android.graphics.Typeface;
import android.util.AttributeSet;
import android.widget.EditText;
/**
* An EditText that applies a custom font.
*
* @author cory@petosky.net
*/
public class EditTextWithCustomFont extends EditText {
private static Typeface customTypeface;
public EditTextWithCustomFont(Context context) {
super(context);
}
public EditTextWithCustomFont(Context context, AttributeSet attrs) {
super(context, attrs);
}
public EditTextWithCustomFont(
Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
/**
* Load and store the custom typeface for this app.
*
* You should have a font file in: project-root/assets/fonts/
*/
private static Typeface getTypeface(Context context) {
if (customTypeface == null) {
customTypeface = Typeface.createFromAsset(
context.getAssets(), "fonts/my_font.ttf");
}
return customTypeface;
}
/**
* Set a custom font for our EditText.
*
* We do this in onAttachedToWindow instead of the constructor to support
* password input types. Internally in TextView, setting the password
* input type overwrites the specified typeface with the system default
* monospace.
*/
@Override protected void onAttachedToWindow() {
super.onAttachedToWindow();
// Our fonts aren't present in developer tools, like live UI
// preview in AndroidStudio.
if (!isInEditMode()) {
setTypeface(getTypeface(getContext()));
}
}
}
