本博文主要讲解怎么使用HorizontalScrollView实现左右滑动的效果。

HorizontalScrollView实际上是一个FrameLayout ，一般通过只放置一个LinearLayout子控件。如果要使其添加其他的控件，就使用LinearLayout子控件来添加其他的控件，最后达到丰富其内容的效果。其中，LinearLayout设置的orientation布局为Horizontal.HorizontalScrollView不可以和ListView同时用，因为ListView有自己的滚动条设置。类似TextView也一样。

下面通过一个实际的实例来讲解HorizontalScrollView:

1.效果：

2.实现代码

需求分析：主要实现一个父LinearLayout中包含代码创建的10个子LinearLayout,而每个子LinearLayout添加一个ImageView和TextView,超出的部分实现左右滑动

activity_main.xml

xmlns:tools="http://schemas.android.com/tools"

android:layout_width="match_parent"

android:layout_height="match_parent"

android:orientation="vertical" >

android:id="@+id/scroll_view"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:background="#00FF00"

android:scrollbarAlwaysDrawHorizontalTrack="false" >

android:id="@+id/linear"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:orientation="horizontal" >

scrollView = (HorizontalScrollView) this.findViewById(R.id.scroll_view);

linear = (LinearLayout) this.findViewById(R.id.linear);

createChildLinearLayout();

}

private void createChildLinearLayout() {

for (int i = 0; i < 10; i++) {

LinearLayout.LayoutParams linearLp = new LinearLayout.LayoutParams(

LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

LinearLayout myLinear = new LinearLayout(this);

linearLp.setMargins(5, 0, 5, 20);

myLinear.setOrientation(LinearLayout.VERTICAL);

myLinear.setTag(i);

linear.addView(myLinear, linearLp);

LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(

LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);

ImageView imageView = new ImageView(this);

imageView.setBackgroundResource(R.drawable.img);

myLinear.addView(imageView, lp);

LinearLayout.LayoutParams textViewLp = new LinearLayout.LayoutParams(

LayoutParams.MATCH_PARENT, LayoutParams.WRAP_CONTENT);

TextView textView = new TextView(this);

textView.setText(i + "");

textView.setGravity(Gravity.CENTER);

myLinear.addView(textView, textViewLp);

myLinear.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

Toast.makeText(MainActivity.this, v.getTag().toString(),

Toast.LENGTH_SHORT).show();

}

});

}

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.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();

if (id == R.id.action_settings) {

return true;

}

return super.onOptionsItemSelected(item);

}

}
