Textview点击显示Imageview再次点击消失

实践要点：

①Imageview可见与不可见 textview.getVisibility(View.Visible)

②Textview点击事件监听 public void onClick(View v)

③Textview状态改变 textview.setTextColor(Color.WHITE)

                         textview.setBackgroundResource(R.drawable.image)    

                         textview.setBackgroundResource(R.color.black)  

这个代码实现的样式功能

1、点击一个背景是图片的textview出现对勾标记，再次点击对勾标记消失
2、当有一个及以上的对勾标记时确认按钮（textview）改变背景与文字颜色

3、当没有一个被标记时点击确定出现toast提示

代码如下

xml主体部分（两个圆形图片是textview，对勾标志是imageview，确认按钮是textview）

                    android:layout_alignParentBottom="true" />

            </LinearLayout>
        </RelativeLayout>
</RelativeLayout>

其中@drawable/fillet_bg是我在drawable里自定义的圆角矩形背景样式，代码如下
后面用到的fillet_bg2是改了背景颜色边框颜色的fillet_bg，代码没有什么区别

<?xml version="1.0" encoding="utf-8"?>
<selector
  xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="false">
        <shape android:shape="rectangle">
            <solid android:color="@color/gray" />
            <corners android:radius="10.0dip" />
            <padding android:left="2.0dip" android:top="2.0dip" android:right="2.0dip" android:bottom="2.0dip" />
        </shape>
    </item>
    <item android:state_pressed="true">
        <shape android:shape="rectangle">
            <solid android:color="@color/gray" />
            <corners android:radius="10.0dip" />
        </shape>
    </item>
</selector>

之后是MainActivity逻辑代码

import android.content.Intent;
import android.graphics.Color;
import android.support.v7.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {
    private ImageView bingo1;
    private ImageView bingo2;
    private TextView one;
    private TextView two;
    private TextView wancheng;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        bingo1 = (ImageView)findViewById(R.id.bingo1);
        bingo2 = (ImageView)findViewById(R.id.bingo2);

        bingo1.setVisibility(View.GONE);
        bingo2.setVisibility(View.GONE);//一开始设置图片不可见
        one = (TextView)findViewById(R.id.one);
        two = (TextView)findViewById(R.id.two);
        wancheng = (TextView)findViewById(R.id.wancheng);
        //  dog.setOnClickListener(this);
        ActionBar actionBar = getSupportActionBar();
        if (actionBar != null) {
            actionBar.hide();
        }
    }
    //点击事件监听
    public void onClick(View v) {
        switch (v.getId()) {
            case R.id.one:
                if ( bingo1.getVisibility() == View.GONE  ){
                    //当点击时对购标志由不可见变为可见
                    bingo1.setVisibility(View.VISIBLE);
                    break;
                }
                else
                    bingo1.setVisibility(View.GONE);
                break;
            case R.id.two:
                if ( bingo2.getVisibility() == View.GONE  ){
                    bingo2.setVisibility(View.VISIBLE);
                    break;
                }
                else
                    bingo2.setVisibility(View.GONE);
                break;

            case R.id.wancheng:
                //当至少有一个对勾标选时可以实现跳转
                if(bingo1.getVisibility() == View.VISIBLE || bingo2.getVisibility() == View.VISIBLE){
                    Intent intent = new Intent(MainActivity.this, Pet_information.class);
                    startActivity(intent);
                    break;
                }else{
                    //当没有对勾标选时toast提示选择
                    Toast.makeText(getApplicationContext(), "请点击选择至少一项", Toast.LENGTH_LONG).show();
                    break;
                }


        }
        //当有标选时改变确定按钮的背景颜色和字体颜色
        if(bingo1.getVisibility() == View.VISIBLE || bingo2.getVisibility() == View.VISIBLE){
            wancheng.setTextColor(Color.WHITE);
            wancheng.setBackgroundResource(R.drawable.fillet_bg2);//当背景是引用图片时为此，单纯颜色时用R.color
        }
        else{
            wancheng.setTextColor(Color.BLACK);
            wancheng.setBackgroundResource(R.drawable.fillet_bg);
        }
    }
