Domanda
ciao a tutti,
Ho scritto qualcosa di simile nel file XML
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TableLayout
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:id="@+id/tl_splash_screen" >
</TableLayout>
</LinearLayout>
.
e in java file
TableLayout tl_splash_screen;
int int_scr_wd;
TableRow tr_test;
TextView txt_test;
TableRow tr_test1;
TextView txt_test1;
TableRow tr_test2;
TextView txt_test2;
TableRow tr_test3;
TextView txt_test3;
TableRow tr_test4;
TextView txt_test4;
TableRow tr_test5;
TextView txt_test5;
int int_tb_bk_col;
int int_black;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.x_splash_screen);
try
{
txt_test=new TextView(this);
txt_test1=new TextView(this);
txt_test2=new TextView(this);
txt_test3=new TextView(this);
txt_test4=new TextView(this);
txt_test5=new TextView(this);
LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(int_scr_wd+300, LayoutParams.FILL_PARENT);
tr_test = (TableRow) new TableRow(this);
tr_test1 = (TableRow) new TableRow(this);
tr_test2 = (TableRow) new TableRow(this);
tr_test3 = (TableRow) new TableRow(this);
tr_test4 = (TableRow) new TableRow(this);
tr_test5 = (TableRow) new TableRow(this);
tl_splash_screen = (TableLayout)findViewById(R.id.tl_splash_screen);
int_tb_bk_col = Color.rgb(211,211,211);
int_black = Color.rgb(0,0,0);
tl_splash_screen.setBackgroundColor(int_tb_bk_col);
txt_test.setTextColor(int_black);
txt_test1.setTextColor(int_black);
txt_test2.setTextColor(int_black);
txt_test3.setTextColor(int_black);
txt_test4.setTextColor(int_black);
txt_test5.setTextColor(int_black);
Display display = getWindowManager().getDefaultDisplay();
int_scr_wd= display.getWidth();
int as = display.getHeight();
Log.i("", String.valueOf(int_scr_wd));
Log.i("", String.valueOf(as));
txt_test1.setHeight(120);
txt_test2.setHeight(120);
txt_test3.setHeight(120);
txt_test4.setHeight(120);
txt_test5.setHeight(120);
txt_test.setText("TextViews");
txt_test1.setText("- TextView 1");
txt_test2.setText("- TextView 2");
txt_test3.setText("- TextView 3");
txt_test4.setText("- TextView 4");
txt_test5.setText("- TextView 5");
tr_test.addView(txt_test);
tr_test1.addView(txt_test1);
tr_test2.addView(txt_test2);
tr_test3.addView(txt_test3);
tr_test4.addView(txt_test4);
tr_test5.addView(txt_test5);
tl_splash_screen.addView(tr_test,new TableLayout.LayoutParams(layoutParams));
tl_splash_screen.addView(tr_test1,new TableLayout.LayoutParams(layoutParams));
tl_splash_screen.addView(tr_test2,new TableLayout.LayoutParams(layoutParams));
tl_splash_screen.addView(tr_test3,new TableLayout.LayoutParams(layoutParams));
tl_splash_screen.addView(tr_test4,new TableLayout.LayoutParams(layoutParams));
tl_splash_screen.addView(tr_test5,new TableLayout.LayoutParams(layoutParams));
}
catch(Exception ex)
{
Log.i("caught error","caught while loading main page");
}
}
.
Solo per dimostrare che ho pubblicato questo codice.Puoi vedere che ho menzionato TextView 5 in cui è scritto il testo "TextView - 5" che non è visibile sullo schermo perché non ho preso tabellayout in vista scorrevole.
Tutto quello che voglio chiedere perché il layout della tabella copre qualche area dello schermo anche se l'ho definito riempimento_parente.
Si prega di suggerire qualcosa.
Soluzione
<supports-screens
android:smallScreens="true"
android:normalScreens="true"
android:largeScreens="true"
