Question

我TextView内有CardView。我想在点击Textview时发生一些功能，但我的android:onClick没有响应点击，因为方法没有被调用。有什么问题？请帮帮我。

这是我的代码：

XML

 <android.support.v7.widget.CardView
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_margin="15dp">
                <LinearLayout

                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:orientation="vertical">
                    <TextView
                        android:layout_width="wrap_content"

                        android:text="Application info"
                        android:textAlignment="center"
                        android:layout_gravity="left"
                        android:layout_margin="10dp"/>
                </LinearLayout>

                <LinearLayout

                    android:layout_margin="30dp"

                            android:gravity="center"
                            android:clickable="true"
                            android:onClick="applicationValid"
                            android:padding="10dp"
                            android:text="Continue"
                            android:textColor="#fff" />
                    </LinearLayout>
                </LinearLayout>
            </android.support.v7.widget.CardView>

我还有两个以上，但是，onClick()正在运行，但不在此工作。在此setOnClickListener()正在运行，但我想使用android:onClick？

我做错了吗？

Answer 1

设置点击您可以关注的任何视图。

假设您有textview

<TextView
    android:id="@+id/tv"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Application info"/>

您可以按照

等java代码设置点击

public void setClick(){
    TextView textView = (TextView) findViewById(R.id.tv);
    textView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
      //                ... your code for click
        }
    });
}

如果您正在使用某个活动，那么您可以通过xml调用您的方法，如

<TextView
    android:id="@+id/tv"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Application info"
    android:onClick="yourMethodName..."/>

请记住，xml点击方式仅适用于活动。

为什么onClick不能在我的代码中工作？
