java - 图像 Intent 不会随机打开。如果我按下图像以便 Intent 起作用

Question

我有六张图片。如果我按第一个图像 Intent 正在工作。但如果我先按第三张图片，它就不起作用了。它正在按顺序工作。

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    ImageView imageView = (ImageView) findViewById(R.id.indoor_activities);
    imageView.bringToFront();
    imageView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
    Intent myIntent = new Intent (MainActivity.this,indoorActivities.class);
    startActivity(myIntent);

    ImageView imageView = (ImageView) findViewById(R.id.outdoor_activities);
    imageView.bringToFront();
    imageView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
    Intent myIntent = new Intent(MainActivity.this, outdoorActivities.class);
    startActivity(myIntent);

Answer 1

您正在 R.id.indoor_activities 中设置其他 View 点击监听器

在上面的代码中，您是说如果用户首先点击 indoor_activities，则每次都将点击监听器分配给 outdoor_activities。

解决这个问题

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    ImageView imageView = (ImageView) findViewById(R.id.indoor_activities);
    imageView.bringToFront();
    imageView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
    Intent myIntent = new Intent (MainActivity.this,indoorActivities.class);
    startActivity(myIntent);
});// click listener for indoor activities
// click listener for outdoor activities when onCreated is called
    ImageView imageView = (ImageView) findViewById(R.id.outdoor_activities);
    imageView.bringToFront();
    imageView.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
    Intent myIntent = new Intent(MainActivity.this, outdoorActivities.class);
    startActivity(myIntent);
});
