Question

例如，我的列表视图中有50个项目。列表视图的项目包含问题，当用户单击该项目时，它将转到下一个活动并显示答案。那怎么能这样做呢。请建议我任何可能有帮助的想法

Answer 1

在FirstActivity.java中

render() {
  return (
      <ListView
        style={styles.container}
        dataSource={this.props.dataSource}
        renderRow={this._renderRow.bind(this)}
      />
    )
}

在SecondActivity.java中

#wrapper {
    position: relative;
    background: url(http://planetbounce.m360.co.uk/wp-content/themes/planetbounce/assets/img/fabric-bg.png);
    background-repeat: repeat;
    z-index: 2;
  width: 100%;
  height: 2000px;
}

#wrapper:before {
    content: '';
    background: url(http://planetbounce.m360.co.uk/wp-content/themes/planetbounce/assets/img/trampology-left-bg.png) no-repeat;
    background-size: contain;
    display: block;
    width: 20%;
    height: 100%;
    position: absolute;
    left: 0;
  top:0;
}

#wrapper:after {
  content: "";
    background: url(http://planetbounce.m360.co.uk/wp-content/themes/planetbounce/assets/img/trampology-right-bg.png) no-repeat;
  background-size: contain;
    display: block;
    width: 20%;
    height: 100%;
    position: absolute;
    right: 0;
    top: 0;
  z-index: 10
}

Answer 2

为了使列表可以点击，请应用setOnItemClickListener。

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> listView, View view,
                                    int position, long id) {
            Intent intent = new Intent(YourCurrentActivity.this, NextActivity.class); 
            startActivity(intent);

        });
