我是安卓新手。我有一个要求，我必须将 imageViews 动态添加到线性布局中，然后必须单独为每个图像设置动画。

我不知道将 imageViews 动态添加到线性布局的方法。请帮帮我。

谢谢

You can add view dynamically like this.

LinearLayout.LayoutParams imParams = 
    new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
ImageView imSex = new ImageView(context);
imSex.setImageResource(getmyImage());

mainlayout.addView(imSex,imParams);

看到这个

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    // setContentView(R.layout.rainbow);
    ImageView tv1 = new ImageView (this);
    tv1.setImageresorce(R.drawable.image1);
    ImageView tv2 = new ImageView (this);
    tv2.setImageresorce(R.drawable.image2);
    ImageView tv3 = new ImageView (this);

    tv3.setGravity(Gravity.CENTER);
    tv3.setImageresorce(R.drawable.image3);
    LinearLayout ll = new LinearLayout(this);
    ll.setOrientation(LinearLayout.VERTICAL);
    ll.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
    ll.setGravity(Gravity.CENTER);
    ll.addView(tv1);
    ll.addView(tv2);
    ll.addView(tv3);
    setContentView(ll);
}

看到这个有用的数据

你可以试试这段代码。它还具有用于设置尺寸的位ImageView以及多个 之间的边距ImageView's。和int dimens = 45是值并且int dimensMargin = 4;正在pixel被转换为 dp。

LinearLayout linlaLikes必须在您的布局中，XML然后在您的活动中投射。

LinearLayout linlaLikes = (LinearLayout) findViewById(R.id.linlaLikes);
ImageView imgUsers = new ImageView(getApplicationContext());

// SET THE IMAGEVIEW DIMENSIONS
int dimens = 45;
float density = getResources().getDisplayMetrics().density;
int finalDimens = (int)(dimens * density);

LinearLayout.LayoutParams imgvwDimens = new LinearLayout.LayoutParams(finalDimens, finalDimens);
imgUsers.setLayoutParams(imgvwDimens);

// SET SCALETYPE
imgUsers.setScaleType(ScaleType.CENTER_CROP);

// SET THE MARGIN
int dimensMargin = 4;
float densityMargin = getResources().getDisplayMetrics().density;
int finalDimensMargin = (int)(dimensMargin * densityMargin);

LinearLayout.LayoutParams imgvwMargin = new LinearLayout.LayoutParams(finalDimens, finalDimens);
imgvwMargin.setMargins(finalDimensMargin, finalDimensMargin, finalDimensMargin, finalDimensMargin);

// SET YOUR IMAGER SOURCE TO YOUR NEW IMAGEVIEW HERE

// ADD THE NEW IMAGEVIEW WITH THE PROFILE PICTURE LOADED TO THE LINEARLAYOUT
linlaLikes.addView(imgUsers, imgvwMargin);

您可以为此http://developer.android.com/guide/components/fragments.html使用片段

FragmentManager fragmentManager = getFragmentManager()
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
ExampleFragment imageFragment = new ExampleFragment();
fragmentTransaction.add(R.id.image_container, imageFragment);
fragmentTransaction.commit();
