我使用引导程序并创建标题固定表和滚动高度。我想制作一张桌子,其中td将随着屏幕尺寸扩展。我在哪里错了?
当我使用IE dev工具分析整个内容时,我看到,如果td高度不包含数据,则td高度将略小于表格(***我不想在td中固定高度,因为我必须输入第三列中的长数据)。如何将div的高度设置为与桌子一样大? 谢谢您的帮助 编辑:我的源代码:
ListView listaCanciones;
List<String> list;
ListAdapter adapter;
MediaPlayer mp; ;
int posicion = 0;
Button play_pause, btn_repetir;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_explorador);
play_pause = (Button)findViewById(R.id.btnPlay_Pause);
listaCanciones = findViewById(R.id.lv);
list = new ArrayList<>();
Field[] fields = R.raw.class.getFields();
for (int i = 0; i < fields.length; i++){
list.add(fields[i].getName());
}
adapter = new ArrayAdapter<>(this, R.layout.list_view_configuracion, list);
listaCanciones.setAdapter(adapter);
listaCanciones.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
if(mp != null ){
mp.stop();
mp.release();
}
int resID = getResources().getIdentifier(list.get(i), "raw", getPackageName());
mp = MediaPlayer.create(Explorador.this, resID);
mp.start();
play_pause.setBackgroundResource(R.drawable.pausa);
//Toast.makeText(getApplicationContext(), "Reproduciendo", Toast.LENGTH_SHORT).show();
}
});
和CSS:
public void Next(View view){
mp.stop();
mp.release();
posicion = (posicion + 1)%list.size();
int u = getResources().getIdentifier(list.get(posicion), "raw", getPackageName());
mp = MediaPlayer.create(getApplicationContext(), u);
mp.start();
}
public void Anterior(View view){
mp.stop();
mp.release();
posicion = (posicion - 1 < 0)? list.size() - 1: posicion-1;
int u = getResources().getIdentifier(list.get(posicion), "raw", getPackageName());
mp = MediaPlayer.create(getApplicationContext(), u);
mp.start();
}
结果:
