次のコードを使用して、Imageviews、ImageIcons[i]の配列の重力を中央に設定したいと思います。 

ImageIcons[i] = new ImageView(this);
ImageIcons[i].setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
layout.addView(ImageIcons[i]);

そして、重力を設定している間、私は立ち往生しています。私は、SOの人々にこれについて私を案内するように頼みます。

ありがとう

これを試して

LinearLayout.LayoutParams layoutParams=new LinearLayout.LayoutParams(width, height);
layoutParams.gravity=Gravity.CENTER;
ImageIcons[i].setLayoutParams(layoutParams);

ビューからレイアウトパラメータを取得し、変更してから再設定します。

image.setBackgroundResource(R.drawable.mobile);
LayoutParams params = (LayoutParams) image.getLayoutParams();
params.gravity = Gravity.CENTER;
image.setLayoutParams(params);

最初に幅をmatch_parentに設定してから、重力を設定します。そうしないと、重力が機能しません。機能することを願っています。

ImageIcons[i].setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
LayoutParams.WRAP_CONTENT));
ImageIcons.setGravity(Gravity.CENTER);

ImageView myImage = new ImageView(this);
FrameLayout.LayoutParams myImageLayout = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT,FrameLayout.LayoutParams.WRAP_CONTENT);
myImageLayout.gravity=Gravity.CENTER_HORIZONTAL | Gravity.CENTER_VERTICAL;
            myImage.setLayoutParams(myImageLayout);

以下のコードは誰かを助けると思います

LinearLayout.LayoutParams layoutParams=new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);
layoutParams.leftMargin = 10;
layoutParams.rightMargin = 10;
parent.addView(tips[i], layoutParams);

あなたImageViewがの子供である場合RelativeLayout

その後、これはうまくいくかもしれません。

public void setLogoPosition(String pos) 
{

    //_Watermark is ImageView Object

    RelativeLayout.LayoutParams layoutParams =
            (RelativeLayout.LayoutParams) _Watermark.getLayoutParams();


    layoutParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT, 0);
    layoutParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT, 0);
    layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, 0);
    layoutParams.addRule(RelativeLayout.CENTER_IN_PARENT, 0);
    layoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP, 0);

    switch (pos) {
        case "topleft":
            layoutParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT, RelativeLayout.TRUE);
            layoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP, RelativeLayout.TRUE);
            break;
        case "topright":
            layoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP, RelativeLayout.TRUE);
            layoutParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT, RelativeLayout.TRUE);
            break;
        case "bottomleft":
            layoutParams.addRule(RelativeLayout.ALIGN_PARENT_LEFT, RelativeLayout.TRUE);
            layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);
            break;
        case "bottomright":
            layoutParams.addRule(RelativeLayout.ALIGN_PARENT_RIGHT, RelativeLayout.TRUE);
            layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);
            break;
        case "center":
            layoutParams.addRule(RelativeLayout.CENTER_IN_PARENT, RelativeLayout.TRUE);
            break;
        case "topcenter":
            layoutParams.addRule(RelativeLayout.CENTER_IN_PARENT, RelativeLayout.TRUE);
            layoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP, RelativeLayout.TRUE);
            break;
        case "bottomcenter":
            layoutParams.addRule(RelativeLayout.CENTER_IN_PARENT, RelativeLayout.TRUE);
            layoutParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM, RelativeLayout.TRUE);
            break;
    }
    _Watermark.setLayoutParams(layoutParams);
}
