Android 断章取义
我有fragment应用程序。但是fragment_home.xml有一个相对的布局和imageview。我开发了代码片段,但当我单击imageview时,它没有运行意图。图像视图需要-Android 断章取义,android,android-intent,layout,fragment,Android,Android Intent,Layout,Fragment,我有fragment应用程序。但是fragment_home.xml有一个相对的布局和imageview。我开发了代码片段,但当我单击imageview时,它没有运行意图。图像视图需要- public class HomeFragment extends Fragment { public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedI
public class HomeFragment extends Fragment {
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_home, container, false);
return rootView;
}
我写这里是为了通过ImageView运行intents。因为我发现java不支持多个extend。像extends片段一样,活动实现。。。等等
public class home extends Activity implements View.OnClickListener {
ImageButton firstModule;
ImageButton secondModule;
ImageButton thirdModule;
ImageButton fourModule;
ImageButton fiveModule;
ImageButton sx;
ImageButton seven;
@Override
public void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_home);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
//init buttons
firstModule = (ImageButton) findViewById(R.id.imageButton1);
secondModule = (ImageButton) findViewById(R.id.imageButton2);
thirdModule = (ImageButton) findViewById(R.id.imageButton3);
fourModule = (ImageButton) findViewById(R.id.imageButton4);
fiveModule = (ImageButton) findViewById(R.id.imageButton5);
sx = (ImageButton) findViewById(R.id.imageButto6);
seven = (ImageButton) findViewById(R.id.imageButton7);
firstModule.setOnClickListener(this);
secondModule.setOnClickListener(this);
thirdModule.setOnClickListener(this);
fourModule.setOnClickListener(this);
fiveModule.setOnClickListener(this);
sx.setOnClickListener(this);
seven.setOnClickListener(this);
}
public void onClick(View v) {
switch (v.getId()) {
case R.id.imageButton1:
startActivity(new Intent(home.this, MainActivitysld.class));
break;
case R.id.imageButton2:
startActivity(new Intent(home.this, xxx.class));
break;
case R.id.imageButton3:
startActivity(new Intent(home.this, xxx.class));
break;
case R.id.imageButton4:
startActivity(new Intent(home.this, xxxx.class));
break;
case R.id.imageButton5:
startActivity(new Intent(home.this, xxx.class));
break;
case R.id.imageButto6:
startActivity(new Intent(home.this, xxx.class));
break;
case R.id.imageButton7:
startActivity(new Intent(home.this, xxx.class));
break;
}
}
编辑:我添加了fragment_home.xml

什么是家。这是什么?
您的片段活动是什么?在startActivity中,您应该给出该活动和类对象的上下文。。
如果调用了onclick方法,请交叉检查..并尝试调试。
如果不是,则设置ImageButton.setclickable(true)。
查看上述选项是否有效。

是片段或活动只需查看片段的良好教程xxx.classes名称xxx.javaClasses在java中应以大写开头。记住这一点。因此,代码更清晰。我将在何处将此代码添加到公共HomeFragment扩展片段{}或者公共主页扩展活动实现OnClickListener?home。这是出于意图。实际上我看到了。我看到了ImageView和silder菜单,我可以更改导航抽屉上的布局,但当我第一次来到布局碎片时,请不要单击ImageView。单击方法是否有效??尝试打印日志..并查看是否正在调用它。。
firstModule = (ImageButton) findViewById(R.id.imageButton1);
firstModule .setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
startActivity(new Intent(home.this, MainActivitysld.class));
}});
// for n numbers
