我确定我做了一些愚蠢的错误，但这是我的问题。

基本上我尝试使用cardviews制作历史列表。在这些卡片视图中，我有一个垂直方向的LinearLayout，可以将我的所有内容都放入我的卡中。

在这个LinearLayout中，我有另一个LinearLayout，其方向为Horizo​​ntal，其中包含标题，....在这个linearLayout下面，我有一个textview，它包含实际的字符串内容。这个内容非常大，出于某种原因它不会包装到下一行。

也许这有点容易理解结构：

CardView

_ LinearLayout(垂直)

_ _ LinearLayout(水平)

_ _ _ Textview

_ _ TextView(这是有问题的那个)

我以编程方式设置这些组件，因为我不知道我需要预先打印多少张卡。

这是代码：

XML：

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:orientation="horizontal"

android:paddingBottom="@dimen/activity_vertical_margin"

android:paddingLeft="@dimen/activity_horizontal_margin"

android:paddingRight="@dimen/activity_horizontal_margin"

android:paddingTop="@dimen/activity_vertical_margin"

tools:context="url.Fragments.History_Fragment">

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_gravity="start">

android:id="@+id/historiekLijst_Layout"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_gravity="start"

android:layout_marginRight="5dp"

android:orientation="vertical">

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_margin="5dp"

android:gravity="start"

android:text="Historiek"

android:textStyle="bold"

android:textSize="25dp"/>

History_Fragment类：

LinearLayout linearLayout = (LinearLayout) historiekView.findViewById(R.id.historiekLijst_Layout);

CardView card = DynamicComponent_Helper.makeNewCardview(5, Gravity.CENTER_HORIZONTAL,Gravity.CENTER , 5, 15, getContext());

TextView title = DynamicComponent_Helper.makeNewTextView(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT, 5, Gravity.START, Gravity.START, 0, 20, "title",getContext());

title.setTypeface(null, Typeface.BOLD);

TextView content= DynamicComponent_Helper.makeNewTextView(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT, 5, Gravity.START, Gravity.START, 0, 15, "content which is too long and doesn't get wrapped",getContext());

LinearLayout titleLayout = DynamicComponent_Helper.makeNewLinearLayout(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT, Gravity.NO_GRAVITY, Gravity.NO_GRAVITY, LinearLayout.HORIZONTAL, getContext());

LinearLayout cardLayout = DynamicComponent_Helper.makeNewLinearLayout(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT, Gravity.CENTER_HORIZONTAL, Gravity.START, LinearLayout.VERTICAL, getContext());

titelLayout.addView(title);

cardLayout.addView(titleLayout);

cardLayout.addView(content);

card.addView(cardLayout);

linearLayout.addView(card);

我的componentCreator_helper：

public static CardView makeNewCardview(int margin, int gravity,int layoutGravity, int radius, int padding, Context context){

// Initialize a new CardView

CardView card = new CardView(context);

// Set the CardView layoutParams

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(

LinearLayout.LayoutParams.MATCH_PARENT,

LinearLayout.LayoutParams.WRAP_CONTENT

);

params.setMargins(geefDPAlsInt(margin, context), geefDPAlsInt(margin, context), geefDPAlsInt(margin, context), geefDPAlsInt(margin, context));

params.gravity = layoutGravity;

card.setLayoutParams(params);

// Set CardView corner radius

card.setRadius(geefDPAlsInt(radius, context));

// Set cardView content padding

card.setContentPadding(geefDPAlsInt(padding, context), geefDPAlsInt(padding, context), geefDPAlsInt(padding, context), geefDPAlsInt(padding, context));

// Set a background color for CardView

card.setCardBackgroundColor(Color.parseColor("#FFFFFF"));

// Set the CardView maximum elevation

card.setMaxCardElevation(15);

// Set CardView elevation

card.setCardElevation(9);

return card;

}

public static LinearLayout makeNewLinearLayout(int width, int length, int gravity, int layoutGravity, int orientation, Context context){

LinearLayout linearLayout = new LinearLayout(context);

LinearLayout.LayoutParams layoutLinearParams =

new LinearLayout.LayoutParams(geefDPAlsInt(width, context), geefDPAlsInt(length, context));

layoutLinearParams.gravity = layoutGravity;

linearLayout.setOrientation(orientation);

linearLayout.setGravity(gravity);

linearLayout.setLayoutParams(layoutLinearParams);

return linearLayout;

}

public static ImageView makeNewImageView(String imageSource, int width, int length, int margin, int gravity, int layoutGravity, int tag, Context context){

ImageView imageView = new ImageView(context);

LinearLayout.LayoutParams imageLayout = new LinearLayout.LayoutParams(geefDPAlsInt(width, context), geefDPAlsInt(length, context));

imageLayout.gravity = layoutGravity;

imageLayout.setMargins(geefDPAlsInt(margin, context), geefDPAlsInt(margin, context), geefDPAlsInt(margin, context), geefDPAlsInt(margin, context));

imageLayout.gravity = gravity;

imageView.setLayoutParams(imageLayout);

imageView.setImageResource(context.getResources().getIdentifier(imageSource, "drawable", context.getPackageName()));

imageView.setTag(tag);

return imageView;

}

public static TextView makeNewTextView(int width, int length, int margin, int gravity, int layoutGravity, int tag, int textsize, String tekst, Context context){

TextView tekstView = new TextView(context);

LinearLayout.LayoutParams layoutTextParams = new LinearLayout.LayoutParams(geefDPAlsInt(width, context), geefDPAlsInt(length, context));

layoutTextParams.setMargins(geefDPAlsInt(margin, context), geefDPAlsInt(margin, context), geefDPAlsInt(margin, context), geefDPAlsInt(margin, context));

layoutTextParams.gravity = layoutGravity;

tekstView.setLayoutParams(layoutTextParams);

tekstView.setGravity(gravity);

tekstView.setText(tekst);

tekstView.setTextSize(TypedValue.COMPLEX_UNIT_SP, textsize);

tekstView.setTag(tag);

return tekstView;

}

所以我尝试了很多我在stackoverflow和互联网上找到的东西。我发现很多但没有用的一些东西是：

content.setMaxWidth(0) => my cards have no more content and the height becomes WAY to big

content.setWidth(0) => same result

content.setInputType(InputType.TYPE_TEXT_FLAG_IME_MULTI_LINE); => no change

content.setSingleLine(false); => no change

content.setMaxLines(10) => no change

content.setHorizontallyScrolling(false); => no change

我也一起试过了其中的一些。我真的希望有人能解决这个问题。哦，是的，它适用于Android 5.1，但不适用于Android版本7。

如果你还在读这行，那么我想明确地感谢你提前花时间和精力！
