java - for循环中的Findviewbyid()

Question

I have tried this ，但我不明白如何为我的变量创建自定义名称。这是我想缩短的代码:

    TextView viewmt1 = (TextView) v.findViewById(R.id.mt1);
    TextView viewmt2 = (TextView) v.findViewById(R.id.mt2);
    TextView viewmt3 = (TextView) v.findViewById(R.id.mt3);
    TextView viewmt4 = (TextView) v.findViewById(R.id.mt4);
    TextView viewmt5 = (TextView) v.findViewById(R.id.mt5);
    TextView viewmt6 = (TextView) v.findViewById(R.id.mt6);
    TextView viewmt7 = (TextView) v.findViewById(R.id.mt7);

    TextView viewtid1 = (TextView) v.findViewById(R.id.tid1);
    TextView viewtid2 = (TextView) v.findViewById(R.id.tid2);
    TextView viewtid3 = (TextView) v.findViewById(R.id.tid3);
    TextView viewtid4 = (TextView) v.findViewById(R.id.tid4);
    TextView viewtid5 = (TextView) v.findViewById(R.id.tid5);
    TextView viewtid6 = (TextView) v.findViewById(R.id.tid6);
    TextView viewtid7 = (TextView) v.findViewById(R.id.tid7);

    ImageView viewImage1 = (ImageView) v.findViewById(R.id.imageView1);
    ImageView viewImage2 = (ImageView) v.findViewById(R.id.imageView2);
    ImageView viewImage3 = (ImageView) v.findViewById(R.id.imageView3);
    ImageView viewImage4 = (ImageView) v.findViewById(R.id.imageView4);
    ImageView viewImage5 = (ImageView) v.findViewById(R.id.imageView5);
    ImageView viewImage6 = (ImageView) v.findViewById(R.id.imageView6);
    ImageView viewImage7 = (ImageView) v.findViewById(R.id.imageView7);

Answer 1

1.初始化TextView、ImageView数组

2.添加for循环

3.获取 View 的id

4.代码中的findViewById

试试这个。

TextView[]  textViews1 = new TextView[7];
TextView[]  textViews2 = new TextView[7];
ImageView[]  imageViews = new ImageView[7];

for (int j = 0; j < 7; j++) {
    String viewmt = "mt" + (i + 1);
    String viewtid = "tid" + (i + 1);
    String viewImage = "imageView" + (i + 1);
    int resIDmt = getResources().getIdentifier(viewmt, "id", getPackageName());
    int resIDtid = getResources().getIdentifier(viewtid, "id", getPackageName());
    int resIDImage = getResources().getIdentifier(viewImage, "id", getPackageName());

    textViews1[j] = ((TextView) v.findViewById(resIDmt));
    textViews2[j] = ((TextView) v.findViewById(resIDtid));
    imageViews[j] = ((ImageView) v.findViewById(resIDImage));
}
