私のアプリで。プログラムで作成された複数の線形レイアウトと仕切りを含むアクティビティがあり、その実行は正常です。

しかし、線形レイアウトと仕切りを5回複製する必要があり、2つのことを除いてすべて同じです:

1-各線形レイアウトには異なる文字列があります。

2-最初の分割マージンは、他の分割マージンとは異なります。

よりクリーンで短いコードでそれを行うためのより良いアプローチがあります。

どんな助けでも大歓迎です。

public class Dreams extends Activity {

@Override
 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Boolean customTitleSupported =  
      requestWindowFeature(Window.FEATURE_CUSTOM_TITLE); 
     setContentView(R.layout.trip);  
     if (customTitleSupported) { 

  getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE,R.layout.custom_title); 
  } 
         TextView tv = (TextView) findViewById(R.id.title); 
         tv.setTypeface(FontFactory.getOldEnglish(getBaseContext()));
         tv.setText("Dreams");  

     LinearLayout ll = (LinearLayout)findViewById(R.id.linearLayout);       
        // add text view

        tv1.setGravity(Gravity.RIGHT);
        tv1.setTextSize(30);    
        tv1.setTypeface(FontFactory.getOldEnglish(getBaseContext()));

変更されているのは TextView setText() だけなので、これを文字列入力のリストで for ループにすることができます。例えば：

LinearLayout ll = (LinearLayout)findViewById(R.id.linearLayout);       

String[] textEntries = {  getString(R.string.dream),
                          getString(R.string.dream_1),
                          getString(R.string.dream_2),
                          getString(R.string.dream_3),
                          getString(R.string.dream_4),
                          getString(R.string.dream_5)
                        };

for ( int i = 0; i < textEntries.length; i++)
{
    TextView tv = new TextView(this);
    tv.setGravity(Gravity.RIGHT);
    tv.setTextSize(30);
    tv.setTypeface(FontFactory.getOldEnglish(getBaseContext()));
    ll.addView(tv);
    tv.setText(Html.fromHtml(textEntries[i]));

    ImageView divider = new ImageView(this);
    LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, 5);
    lp.setMargins(10, 10, 10, 10);
    divider.setLayoutParams(lp);
    divider.setBackgroundColor(Color.RED);
    ll.addView(divider);
}
