動態創建線性佈局不會包裝內容

Question

我想動態地添加文字瀏覽內LinearLayout。一旦所有文字瀏覽的寬度都大於屏幕寬度，我需要在第一個文字的下方創建另一個LinearLayout並繼續添加文字瀏覽。我基本上是將String分成多個文字瀏覽，因爲我需要檢查一些文字是否在前面有'＃'。如果是這樣，我需要改變顏色。我遇到的問題是第一個LinearLayout非常高（高度不包裹內容）。任何幫助？

LinC是linearLayout計數器。它得到增加，一旦textviews的寬度比屏幕更大

 public void TextMod() 
{ 
    LinearLayout.LayoutParams layoutParams,layoutParams2; 
    layoutParams= new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT); 
    layoutParams= new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT); 
    llay= new LinearLayout(this.c); 
    llay.setOrientation(LinearLayout.HORIZONTAL); 
    llay.setBackgroundColor(Color.GREEN); 
    llay2= new LinearLayout(this.c); 
    llay2.setBackgroundColor(Color.MAGENTA); 
    llay2.setOrientation(LinearLayout.HORIZONTAL); 
    Boolean addl =true; 
     String parts[]= this.Dis.split(" "); 
     size=parts.length; 
     int i=0; 
     while(i<size) 
     { 
      // 
      if(textview_wid < this.w) 
      { 
       TextView valueTV = new TextView(c); 
       String d= parts[i] + " "; 
       valueTV.setText(d); 
       valueTV.measure(MeasureSpec.UNSPECIFIED, MeasureSpec.UNSPECIFIED);  
       textview_wid +=valueTV.getMeasuredWidth(); 
       Log.d(" des", " TEEXT WIDTH " + valueTV.getMeasuredWidth()); 
       if(d.charAt(0)=='#') 
       { 
        valueTV.setTextColor(Color.MAGENTA); 
       } 
       if(addl) 
       { 
        if(LinC==0) 
        { 
         llay.setLayoutParams(layoutParams); 
         this.Lin.addView(llay); 
        } 
        if(LinC==1) 
        { 
         llay2.setLayoutParams(layoutParams); 
         this.Lin.addView(llay2); 
        } 



        addl=false; 

       } 

       valueTV.setLayoutParams(layoutParams); 

       if(LinC==0)llay.addView(valueTV); 
       if(LinC==1)llay2.addView(valueTV); 
       i++; 
      } 
      else 
      { 

       Log.d(" des", " TOTAL TEXTVIE WIDE " + textview_wid); 
       textview_wid =0; 
       LinC++; 
       addl=true; 

      } 


     // valueTV.setLayoutParams(layoutParams); 




     } 

} 

的OnCreate

  @Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    DisplayMetrics metrics = new DisplayMetrics(); 
    getWindowManager().getDefaultDisplay().getMetrics(metrics); 

    height =metrics.heightPixels; 
    width=metrics.widthPixels; 
    L=(LinearLayout)findViewById(R.id.ll); 

    //layoutParams= new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT); 

    sep = new DescriptionStringSep(s,L,this,width); 
    sep.TextMod(); 


} 

XML

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
android:layout_width="match_parent" 

android:layout_height="match_parent" 
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=".MainActivity" > 



<LinearLayout 
     android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:id="@+id/ll" 
    android:orientation="vertical" 

    > 



</LinearLayout> 

</RelativeLayout>

你做錯了什麼

setContentView(R.layout.activity_main); 

這將內容視圖設置爲xml佈局作爲參數傳遞。由於您在TextMod方法中創建了動態佈局，因此稍後在代碼中調用該佈局，並將結果佈局設置爲您的活動。你應該這樣做

onCreate(){ 
    ... 
    LinearLayout mLayout; 
    mLayout = sep.TextMod(); // make TextMod return the root view 
    setContentView(mLayout); 
}
