我有一个ImageViews数组。单击这些ImageView即可选择它们。它们的笔触属性从0(未选中)到4(已选中)变化。现在,我有两个按钮,“ ClearAll”和“ Back”。如果单击后退按钮,则所有选中的ImageViews描述将显示在Toast消息中(例如,“您已选择iv1,iv2,iv3”)。 “ ClearAll”按钮的作用是清除选择-假设我单击了ImageView 1、2和3-如果单击“ ClearAll”,则它们的笔划将回到0(指示所有选择均被清除) 。但是我有一个问题,假设我单击了ImageView 1、2和3,然后改变了主意,我想单击ImageView 4、5、6,然后单击“返回”。 Toast消息显示了我也清除过的那些ImageView的描述,输出是这样的,“您选择了iv1,iv2,iv3,iv4,iv5,iv6。如何修复我的代码,以便已被“ ClearAll”清除,不会在Toast中显示?

这是上面每个代码的片段。

ImageViews:

for (int i = 0 ; i < color.length ; i++) {
        color[i] = (ImageView) findViewById (ivCirclesId[i]);
        final GradientDrawable ivCircleOnClick = (GradientDrawable) color[i].getBackground ();
        color[i].setTag ("0");
        color[i].setOnClickListener (new OnClickListener() {

            public void onClick (View v) {
                if (v.getTag ().toString ().equals ("1")) {
                    --ctr;
                    v.setTag ("0");
                    ivCircleOnClick.setStroke (0, Color.WHITE);
                } else {
                    if(ctr >= 8) {
                        Toast.makeText (getApplicationContext (), "Limit reached!", Toast.LENGTH_SHORT).show ();
                        return;
                    }
                    ++ctr;
                    v.setTag ("1");
                    ivCircleOnClick.setStroke (4, Color.WHITE);
                    message = message + "#" + v.getContentDescription ();
                    return;
                }
            }
        });


ClearAll:

Button btnClear = (Button) findViewById (R.id.btnClearAll);
    btnClear.setOnClickListener (new OnClickListener () {

        @Override
        public void onClick (View v) {
            for (int i = 0 ; i < color.length; i++) {
                final GradientDrawable ivCircleOnClick = (GradientDrawable) color[i].getBackground ();
                ivCircleOnClick.setStroke (0, Color.WHITE);
                color[i].setTag ("0");
                ctr = 0;
            }
        }
    });


背部:

Button btnBack = (Button) findViewById (R.id.btnBack);
    btnBack.setOnClickListener (new OnClickListener () {

        @Override
        public void onClick (View v) {
            if (ctr >= 1) {
                Toast.makeText (Filter.this, message, Toast.LENGTH_SHORT).show();
                message = "";
            }
            finish();
        }
    });

最佳答案

当您仅取消选择一个图像视图时,这也应该起作用。希望这可以帮助.....

ImageViews:

for (int i = 0 ; i < color.length ; i++) {
    color[i] = (ImageView) findViewById (ivCirclesId[i]);
    final GradientDrawable ivCircleOnClick = (GradientDrawable) color[i].getBackground ();
    color[i].setTag ("0");
    color[i].setOnClickListener (new OnClickListener() {

        public void onClick (View v) {
            if (v.getTag ().toString ().equals ("1")) {
                --ctr;
                v.setTag ("0");
                ivCircleOnClick.setStroke (0, Color.WHITE);
            } else {
                if(ctr >= 8) {
                    Toast.makeText (getApplicationContext (), "Limit reached!", Toast.LENGTH_SHORT).show ();
                    return;
                }
                ++ctr;
                v.setTag ("1");
                ivCircleOnClick.setStroke (4, Color.WHITE);
                //message = message + "#" + v.getContentDescription ();
                return;
            }
        }
    });


ClearAll:

Button btnClear = (Button) findViewById (R.id.btnClearAll);
btnClear.setOnClickListener (new OnClickListener () {

    @Override

        for (int i = 0 ; i < color.length; i++) {
            final GradientDrawable ivCircleOnClick = (GradientDrawable) color[i].getBackground ();
            ivCircleOnClick.setStroke (0, Color.WHITE);
            color[i].setTag ("0");
            ctr = 0;
            message = "";
        }
    }
});


背部:

Button btnBack = (Button) findViewById (R.id.btnBack);
btnBack.setOnClickListener (new OnClickListener () {

    @Override
    public void onClick (View v) {
        message = "";
        for(int i = 0 ; i < color.length ; i++){
             if(color[i].getTag().toString().equals("1")){
                  message = message + "#" + color[i].getContentDescription();
             }
        }
        if (ctr >= 1) {
            Toast.makeText (Filter.this, message, Toast.LENGTH_SHORT).show();
            message = "";
        }
        //finish();
    }
});
