Question

我正在尝试使用ViewFlipper，但我在setContentView(R.layout.activity_main);行收到此错误;

当我回溯时，我只在添加第二个LinearLayout时出现此错误。我查看了使用ViewFlipper的示例，我没有看到问题。

这是XML文件：

<LinearLayout

            </HorizontalScrollView>
        </ScrollView>
    </linearLayout>

</ViewFlipper>

</LinearLayout>

以下是活动：

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.ViewFlipper;

public class MainActivity extends AppCompatActivity {

private ViewFlipper viewFlipper;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    //viewFlipper = (ViewFlipper) findViewById(R.id.viewFlipper);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();

    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}

public void viewTimeSheet(View view){
    viewFlipper.showNext();
}
}

这是错误：

下面：

<linearLayout
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    ...

</linearLayout>

应该是：

<LinearLayout
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    ...

</LinearLayout>

（上限）
