我有一个讨厌的问题。我在EditText
内有ScrollView
(8行)。当我试图在EditText
中滚动文本时,它的行为并不稳定。有时它会滚动,有时它不会聚焦。
这是我的布局文件,让我的问题更清晰:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="8dp" >
<TextView
android:id="@+id/wo_task_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/no_description" />
<TextView
android:id="@+id/wo_task_description"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/no_description" />
<TextView
android:id="@+id/wo_task_comments_label"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:text="@string/comments" />
<Button
android:id="@+id/wo_task_select_comment"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="@string/select_comment_from_template" />
<EditText
android:id="@+id/wo_task_comments"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="top|left"
android:hint="@string/enter_your_comment_here"
android:lines="8"
android:maxLines="10"
android:minLines="6"
android:scrollbars="vertical"
android:singleLine="false" />
</LinearLayout>
我知道我遇到这个问题是因为在另一个内部有一个可滚动控件,但我不知道该如何处理。所以,如果可以,请帮助我。
提前致谢。
public void initComments(final View view) {
EditText comment = (EditText) view.findViewById(R.id.wo_task_comments);
comment.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(final View v, final MotionEvent motionEvent) {
if (view.getId() == R.id.wo_task_comments) {
view.getParent().requestDisallowInterceptTouchEvent(true);
switch (motionEvent.getAction() & MotionEvent.ACTION_MASK) {
case MotionEvent.ACTION_UP:
view.getParent().requestDisallowInterceptTouchEvent(
false);
break;
}
}
return false;
}
});
comment.setText(currentTask.getComment() + "very very long comment"
+ "very very long comment\n" + "very very long comment\n"
+ "very very long comment\n" + "very very long comment\n"
+ "very very long comment");
}
我试过这个,没有结果。我仍然无法滚动我的编辑框。

尝试:
@Override
public void onCreate(Bundle savedInstanceState) {
.....
EditText et = (EditText)findViewById(R.id.wo_task_comments);
et.setOnTouchListener(this);
.....
}
@Override
public boolean onTouch(View view, MotionEvent motionEvent) {
if(view.getId() == R.id.wo_task_comments){
view.getParent().requestDisallowInterceptTouchEvent(true);
switch (motionEvent.getAction() & MotionEvent.ACTION_MASK) {
case MotionEvent.ACTION_UP:
view.getParent().requestDisallowInterceptTouchEvent(false);
break;
}
}
return false;
}
在你的情况下:
public class MyActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
initComments(findViewById(R.id.YOUR_MAIN_LAYOUT_ID));
}
public void initComments(final View view) {
EditText comment = (EditText) view.findViewById(R.id.wo_task_comments);
comment.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(final View v, final MotionEvent motionEvent) {
if (v.getId() == R.id.wo_task_comments) {
v.getParent().requestDisallowInterceptTouchEvent(true);
switch (motionEvent.getAction() & MotionEvent.ACTION_MASK) {
case MotionEvent.ACTION_UP:
v.getParent().requestDisallowInterceptTouchEvent(
false);
break;
}
}
return false;
}
});
comment.setText("very very long comment"
+ "very very long comment\n" + "very very long comment\n"
+ "very very long comment\n" + "very very long comment\n"
+ "very very long comment\n" + "very very long comment\n"
+ "very very long comment\n" + "very very long comment\n"
+ "very very long comment\n" + "very very long comment\n"
+ "very very long comment\n" + "very very long comment\n"
+ "very very long comment\n" + "very very long comment\n"
+ "very very long comment\n" + "very very long comment\n"
+ "very very long comment");
}
}

Shilkin的代码效果很好。我使它更强一些。现在它处理的情况是EditText的直接父级不是ScrollView(例如,EditText在放入scrollview之前包装在LinearLayout中)。
方法代码:
public static void handleEditTextScrollable(EditText editText, final int resId) {
editText.setOnTouchListener(new View.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
if (v.getId() == resId) {
ViewParent parent = v.getParent();
while (!(parent instanceof ScrollView)) {
parent = parent.getParent();
}
parent.requestDisallowInterceptTouchEvent(true);
switch (event.getAction() & MotionEvent.ACTION_MASK) {
case MotionEvent.ACTION_UP:
parent.requestDisallowInterceptTouchEvent(false);
break;
}
}
return false;
}
});
}
这样称呼:
handleEditTextScrollable(comment, R.id.wo_task_comments);

一个选项是将子EditText
的高度设置为总最大行的高度(max_lines * font_height)。因此,内部滚动将关闭,唯一的滚动将是父滚动。
