setLayoutParams() 在 API <= 23 中不起作用
setLayoutParams() is not working in API <= 23
我试图将一个句子拆分成单词并将这些单词作为 TextView 放入 RelativeLayout 中,但是当我将 layoutparams 设置为 TextView 时,在 API 23 及更早版本中不生效。只有当我使用 LinearLayout.LayoutParams 而不是 RelativeLayout.LayoutParams.
时,它才能在 API 24 和更新版本中正常工作
这是我的拆分方法:
public void splitWords(){
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
int size = 0;
int bgId = 0;
leftM = convertToDp(5);
String [] splitSentence = sentence.split(" ");
size = splitSentence.length;
bgId = R.drawable.word_bg;
for (int i = 0;i < size;i++){
final TextView word = new TextView(this);
word.setText(splitSentence[i]);
word.setBackgroundResource(bgId);
word.measure(0, 0);
int butonWidth = word.getMeasuredWidth();
if(width - convertToDp(60) - leftM <= butonWidth){
leftM = convertToDp(5);
topM += butonWidth + 5;
}
params.leftMargin = leftM + 2;
params.topMargin = topM;
word.setLayoutParams(params);
leftM += butonWidth;
wordsContainer.addView(word);
}
wordsContainer.setGravity(Gravity.CENTER);
}
这是我的 RelativeLayout:
<RelativeLayout
android:id="@+id/wordsContainer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_marginLeft="2dp"
android:layout_marginTop="20dp"
android:layout_marginRight="2dp"
android:background="@drawable/white_bg_no_border"
android:elevation="2dp"
android:orientation="vertical"
android:paddingLeft="20dp"
android:paddingTop="30dp"
android:paddingRight="20dp"
android:paddingBottom="50dp" />
您需要为子视图创建单独的布局参数,而不是为所有子视图使用一个。在您的代码中将其更改为 Loop
