Android：按钮的onelment onclick（）
|
我有这个xml布局：
<?xml version=\"1.0\" encoding=\"utf-8\"?>
<LinearLayout android:orientation=\"vertical\"
xmlns:android=\"http://schemas.android.com/apk/res/android\"
android:layout_width=\"fill_parent\" android:layout_height=\"fill_parent\">
<LinearLayout android:orientation=\"vertical\" android:background=\"@color/white\" android:layout_width=\"fill_parent\" android:layout_height=\"200px\">
<TextView
android:layout_x=\"0dp\"
android:layout_y=\"10dp\"
android:layout_gravity=\"left\"
android:layout_width=\"wrap_content\"
android:layout_height=\"wrap_content\"
android:textSize=\"15dp\"
android:textColor=\"@color/white\"
android:text=\"Name: \" />
<EditText
android:layout_x = \"20px\"
android:layout_y = \"10px\"
android:layout_gravity=\"left\"
android:textSize=\"15sp\"
android:id=\"@+id/et_username\" android:textColor=\"@color/black\"
android:layout_width=\"150px\"
android:layout_height=\"50px\" />
<Button
android:layout_x = \"200px\"
android:layout_y = \"10px\"
android:layout_gravity=\"left\"
android:textSize=\"16sp\"
android:layout_width=\"96px\"
android:layout_height=\"50px\"
android:background =\"@drawable/login\"
android:id=\"@+id/btn_login\"
android:textColor=\"@color/white\"
android:text=\"next\"
android:onClick=\"onLoginClicked\" />
</AbsoluteLayout>
</LinearLayout>
public class ButtonAdapter extends BaseAdapter {
...
public View getView(int position, View convertView, ViewGroup parent) {
return LayoutInflater.from(mContext).inflate(R.layout.custom_keyboard, null);
}
public void onLoginClicked(View v) {
Button button = (Button) v;
String key = button.getText().toString();
anotherMethod(key, false);
}
...
}
GridView gridview = new GridView(context);
gridview2.setAdapter(new KeyboardAdapter(1, context));
java.lang.IllegalStateException: Could not find a method onLoginClicked(View) in the activity class MainActivity for onClick handler on view class android.widget.Button

<Button android:layout_x = \"200px\" android:layout_y = \"10px\" android:layout_gravity=\"left\" android:textSize=\"16sp\" android:layout_width=\"96px\" android:layout_height=\"50px\" android:background =\"@drawable/login\" android:id=\"@+id/btn_login\" android:textColor=\"@color/white\" android:text=\"next\" android:onClick=\"onLoginClicked\" />public void onLoginClicked(View v) { //toast, log, open activity, etc }赐黄
Button b=(Button)findViewId(R.id.btn_login); b.setOnClickListener(new OnClickListener(){ //perform your action here });抹持奠糙驰
Button button = (Button)findViewById(R.id.btn_login); button.setOnClickListener(new OnClickListener(){ String key = button.getText().toString(); anotherMethod(key, false); });
