}

当我点击cardview时，应该打开对话框。如何将Onclicklistener写入cardview。我没有使用任何Recyclerview。我很震惊。如何将Onclick写入cardview。 任何帮助将不胜感激。

Answer 1

试试这个...在你的onCreate写

  CardView c1 = (CardView) findViewById(R.id.c1);
  c1 .setOnClickListener(this);

和点击方法

 @Override
public void onClick(View v) {

    switch (v.getId()) {

        case R.id.c1:
         //call your dialog box method here
           Details();
            break;

    }
}

对话框的方法

  AlertDialog alert;
// Alert dialog box method
private void Details(){
    AlertDialog.Builder builder = new AlertDialog.Builder(this,R.style.MyAlertDialogStyle);

    builder.setMessage("Please subscribe to use the premium version")
            .setCancelable(false)
            .setPositiveButton( getResources().getString(R.string.ok), new DialogInterface.OnClickListener()
            {
                public void onClick(final DialogInterface dialog, int id) {

                }
            }
            );


    //dialog box details
    alert = builder.create();
    alert.setTitle("Enter Details");
    alert.show();
}

如果您没有主题

，请在style.xml文件中设置此主题

    <style name="MyAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
    <!-- Used for the buttons -->
    <item name="colorAccent">#FFFFFF</item>
    <!-- Used for the title and text -->
    <item name="android:textColorPrimary">#FFFFFF</item>
    <!-- Used for the background -->
    <item name="android:background">@color/colorPrimaryDark</item>
</style>

Answer 2

将此添加到您的活动onCreate。

findViewById(R.id.c1).setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View view) {
        // Open Dialog here.
    }
});

Answer 3

试试这个：

public class MainActivity extends AppCompatActivity implements 
OnClickListener {

final Context context = this;
private CardView mcardView;

public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mcardView = (CardView) findViewById(R.id.c1);

    mcardView.setOnClickListner(this);
}

@Override
public void onClick(View view) 
    {
        if (view == mcardView) {
            Details();
        }
    }

public void Details() {
    final Dialog dialog = new Dialog(context);
    dialog.setContentView(R.layout.first);
    dialog.setTitle("Enter Details");

    // set the custom dialog components - text, image and button
    EditText act_name = (EditText) dialog.findViewById(R.id.act_name);
    EditText act_age = (EditText) dialog.findViewById(R.id.act_age);
    EditText act_relation = (EditText) dialog.findViewById(R.id.act_relation);
    EditText act_occupation = (EditText) dialog.findViewById(R.id.act_occupation);
    //text.setText("Android custom dialog example!");
    //ImageView image = (ImageView) dialog.findViewById(R.id.image);
    //  image.setImageResource(R.drawable.ic_launcher);

    Button ok_btn = (Button) dialog.findViewById(R.id.okbtn);
    // if button is clicked, close the custom dialog
    ok_btn.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            dialog.dismiss();
        }
    });

    dialog.show();
}
}
