所以我一直在嘗試這樣做，它基本上說我試圖獲得的“內容”為空。這是我正在測試的代碼（注釋部分是我試圖讓它工作的實際代碼，我只是添加了 println 以查看獲取的數據是否正確，事實并非如此）public void FiltarBusqueda(String filtro) { int count=0; for (int r = 0; r < mTableLayout.getChildCount(); r++) { TableRow trow = (TableRow) mTableLayout.getChildAt(r); for(int c=0;c <= trow.getChildCount();c++){ System.out.println(""+trow.getChildAt(c)); /*if (trow.getChildAt(c).toString() != filtro) { count++; } if(count==3){ mTableLayout.removeView(trow); }*/ } }}public void onClickFiltro(View v){ EditText filtro = (EditText)findViewById(R.id.txtproducto); FiltarBusqueda(filtro.getText().toString());}*此外，為每個創建 tablerows 的東西在同一個類中 *LinearLayout Thing：final LinearLayout layCustomer = new LinearLayout(this); layCustomer.setOrientation(LinearLayout.VERTICAL); layCustomer.setPadding(0, 10, 0, 10); layCustomer.setBackgroundColor(Color.parseColor("#f8f8f8")); final TextView tv3 = new TextView(this); if (i == -1) { tv3.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.MATCH_PARENT)); tv3.setPadding(5, 5, 0, 5); tv3.setTextSize(TypedValue.COMPLEX_UNIT_PX, smallTextSize); } else { tv3.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.MATCH_PARENT)); tv3.setPadding(5, 0, 0, 5); tv3.setTextSize(TypedValue.COMPLEX_UNIT_PX, textSize); }

TextView#toString()不會在該 TextView 中獲取文本。它只打印類名和實例哈希碼。您需要使用TextView#getText()#toString().
用這個：
public void FiltarBusqueda(String filtro) {
for (int r = 0; r < mTableLayout.getChildCount(); r++) {
TableRow trow = (TableRow) mTableLayout.getChildAt(r);
boolean hasMatch = false;
for (int c = 0; c <= trow.getChildCount(); c++) {
String text = ((TextView) trow.getChildAt(c)).getText().toString();
hasMatch = text.equals(filtro); //when comparing Strings, use `equals()` not `==`
if (hasMatch) break;
}
if (!hasMatch) {
mTableLayout.removeRow(trow);
}
}
}
